ESG INTEGRATED PORTFOLIO CONSTRUCTION AND MANAGEMENT

A

ESG integration occurs on various different investment levels, each necessitating its own framework for analysis and implementation. Where previous chapters have described ESG integration at the underlying security level, this chapter examines different approaches, research and methodologies for integrating it, starting at strategic asset allocation, and moving on to portfolio construction and management.
Much of the existing evidence supporting ESG integration draws upon single security and issuer case studies. The fact that ESG integration is comparatively less developed as investors elevate the decision-making process to
higher levels – asset allocation, fund manager selection and portfolio investment – makes it an exciting area for innovation. This is particularly true as investors build more robust ESG capabilities outside of the traditional equities focus of ESG; these areas include:
▶ mixed asset;
▶ real assets; and
▶ sovereign debt.
Nonetheless, investors should recognise the trade-offs – both explicit and implicit – to risk-adjusted returns when integrating ESG screening approaches.
Accordingly, this chapter draws upon portfolio management theory complemented with examples of investment best practices to:
▶ discuss research, approaches and challenges to embedding ESG investing risk into global asset allocation models;
▶ examine how ESG investing can be applied to approaches across asset classes and different strategy types;
▶ consider how ESG can leverage quantitative research methods to understand risk exposure and performance return dynamics in portfolios; and
▶ differentiate between actively and passively managed ESG strategies.

Q

Approaches to integrating ESG

As the earlier chapters demonstrate, there is a rich diversity of approaches for integrating ESG at the individual securities level.

This heterogeneity is now carrying over to portfolio construction and management, where new methodologies and frameworks are leveraging ESG data sets with innovations that drive fundamental and quantitative, as well as active and passive, investment strategies.

The endgame for ESG integration is the combination of underlying ESG analysis to produce a more complete picture of ESG exposure and risk at the portfolio construction and management levels.

In this respect, ESG integration within
portfolio management

requires a different manner of explanatory power than integration at the individual security level:

it should embed ESG considerations into:

*portfolio exposure;
*risk management;
performance attribution;
and
at the highest level,
**
asset allocation decisions.

New methodologies are now working to combine multiple portfolios to produce a picture of ESG risk and exposure at the asset allocation level.

A

Nonetheless, it is important to acknowledge the notable misperceptions when applying ESG at the portfolio level.

Accordingly, this chapter will attempt to address the following questions:

How can we characterise interest and demand for investment strategies in this area?

What exactly do we mean by ‘ESG strategies’, and how can we understand this approach within the broader language of responsible investment?

What are the assumptions underlying the claim for alpha generation and how can we extend them to include portfolio management and construction more generally?

Perhaps because of its acronym form, ‘ESG’ has emerged as a catch-all term characterising responsible investment strategies.

However, this usage combines many distinct approaches that are often fundamentally different.

Hence, it is useful to understand that ‘responsible investment’ as a term provides a broader, more appropriate characterisation to describe the diversity of investment strategies this chapter addresses.

Q

An unfortunate consequence is that investors and the wider market often conflate the terminology of ‘responsible investment’.

Although a wide diversity of approaches and methodologies co-exist under this umbrella term, ‘responsible investment’ generally characterises three dominant approaches, which we will look at in further detail in this chapter:

A
  1. exclusions-based investing;
  2. ESG investing; and
  3. impact investing.

• Positive screening
• Reinforces engagement activities 
• Reporting capabilities

Impact investing

  • Framework-oriented (UN SDGs)
  • Measurable objectives and outcomes
A

Statistics published by the Principles for Responsible Investment (PRI) are often used to frame investor activities in ESG integration. But what do these statistics really reveal about ESG integration at the portfolio level?

Data compiled by Mercer Consulting (see Table 8.1), one of the largest global institutional investment advisers, suggests that progress in ESG integration is marked by a high degree of variation depending on asset class and investment strategy type.

What is perhaps more interesting, though, is that this data reinforces the notion that integration is broadly more advanced across managers despite being slower to manifest itself through formal- and dedicated sustainability-themed strategies.

Q

the role of portfolio manager is distinct from that of an investment research analyst.

The role of analysts

Analysts (particularly fundamental analysts) present and justify their views in ‘a story’ or ‘investment thesis’ of a security, which generally entails incorporating different factors. These factors often include:

the intrinsic value of the security;
credit analysis;
the potential for a rerating or derating in valuation;
potential risks;
short-term and long-term catalysts; and
an expectation on the security’s earnings growth and cash flow profile.

ESG is an increasingly recognised element within securities analysis and, if material enough, may likely carry meaningful implications that help the investment thesis.

A

The role of portfolio managers

The role of portfolio managers, on the other hand, is of much broader scope.

A portfolio manager constructs and manages a portfolio through a careful process that aggregates all of the individual, underlying risks.

And while portfolio managers often form their own views for a given security, their primary role is to weigh security- specific conviction against:

▶ macro- and micro-economic data;
▶ portfolio exposure; and
▶ sensitivities to potential shocks.

The treatment of ESG in a portfolio context – if properly and systematically integrated, regardless of whether in active or passive portfolio management – should be considered in the same light as these other factors.

The challenge that portfolio managers face is how to widen the focus of research and datasets largely optimised for security analysis into tools that can better inform portfolio and asset allocation analysis and decision-making, particularly in understanding where and how ESG contributes to risk-adjusted returns.

Q

To this end, the ESG framework should illustrate a continuity from micro- to macro-forms of analysis, including:

▶ the organising principles and methodologies for ESG analysis;

▶ the identification and analysis of financial and non-financial (ESG) materiality at the individual security level;

▶ the approaches to build a composite picture of risks and exposure at a single portfolio level; and

▶ the representation of ESG risks and exposure that informs a mixed asset strategy which may include many different, underlying strategies.

In addition, ESG integration should be considered in light of two approaches: discretionary and quantitative investment strategies.

A

Discretionary ESG investment strategies most commonly take the form of a fundamental portfolio approach.

A portfolio manager would work to complement bottom-up financial analysis alongside the consideration of ESG factors to reinforce the investment thesis of a particular holding.

The portfolio manager would then work to understand the aggregate risk at the portfolio level across all factors to understand correlation and event risks, and potential shocks to the portfolio.

Approaches may assume several forms when integrating ESG.

Traditionally, passive or index-based strategies have been the most popular investment vehicles.

These impose a custom index, typically with exclusion criteria.

However, quantitative approaches are now becoming more sophisticated and rigorous when integrated into ESG, from beta-plus funds to single and multi-factor ESG models.

ESG integration can focus on risks as well as opportunities.

A bias towards looking at one of these can lead to different return profiles at the portfolio level as the emphasis can shift from downside protection to upside participation.

Q

Developing a policy that reflects ESG-integrated portfolio management

As a matter of definition – to the market, clients and stakeholders –

an ESG policy should formally outline the investment approach and degree of ESG integration within a firm.

Particularly, asset managers should have ESG policies for asset classes and approach used.

The PRI provides guidance and templates to develop ESG policies.

A


There are well-established resources for developing a comprehensive ESG policy, though these have traditionally catered to the long-only equities and fixed income strategies.4 It is worth noting that investor organisations are now addressing policy development in alternative investment areas, including hedge funds.

Q

Broadly speaking, ESG external research and analysis can be categorised between

academic research and practitioner research.

Each of these resources offers their own unique advantages and disadvantages for investors.

While meta-analyses surveying more than 2,000 academic studies indicate an overall positive bias in the linkage between ESG and investment returns (see Figure 8.3), academic studies on an individual basis often end up disconnected from practice and are not widely or generally applicable.

While certainly additive to the overall discussion, these are often unhelpful for practitioners who tend to search for cross-regional and -temporal factors or frameworks that can be universally or generally applied to portfolios.

Practitioner research, on the other hand, is often less rigorous than academic work, and tends to be less conservative in its assertion to correlate ESG with investment returns, sometimes ignoring other causal factors at play.

A

As the ESG industry matures, institutional investors are finding an increasingly diverse universe of external research resources.

These resources now include not only ESG-specific research content, but also new quantitative techniques such as natural language processing, machine learning and even artificial intelligence to organise ESG data.

Indeed, the market for ESG content and indices is expected to grow from US$300 million in 2016 to almost US$1 billion by 2021.

These complement internal investment research as well as providing internal quantitative and performance analytics teams the opportunity to refine methodologies for managing ESG risk.

Just as external providers are innovating ESG datasets and producing research, so too are investors developing in-house capabilities to differentiate themselves across asset classes as well as investment strategy types.

Q

For most investors, the sheer breadth and diversity of external ESG research represents a difficult resource to replicate by internal research analysts. While research (such as ESG ratings from third-party data providers) comes at a cost, many of these other resources are openly available.

A

The list of practitioner resources, though by no means exhaustive, includes:

▶ sell-side research and analysis;
▶ academic studies;
▶ investment consultant research;
▶ third-party ESG data provider research;
▶ ESG-integrated fund distribution platforms;
▶ asset owner and asset manager white papers;
▶ investor initiative research;
▶ non-governmental organisations (NGOs) research;
▶ governmental agencies and central banks; and
▶ multilateral institutions and agencies.

Q

ecommendations by the Task Force on Climate-related Financial Disclosures (TCFD) provide an important example, for both a move towards ESG standards convergence and in elevating risk exposure metrics to the portfolio level from the underlying asset level.

Where carbon intensity was previously determined in the form of carbon footprint on a per company or per asset basis, portfolio managers may now treat carbon exposure on a portfolio-weighted basis.

Weighted-average carbon intensity measures a portfolio’s exposure to carbon- intensive companies on a position-weighted carbon exposure.

Calculated as the carbon intensity (Scope 1 + 2 Emissions ÷ US$ million revenues) weighted for each position within a portfolio, this metric can be employed by investors to

***tilt or overlay portfolios towards lower-carbon exposure.

Q

Investors should recognise the need to differentiate themselves irrespective of their approach to ESG integration.

Asset owners continue to rebase their expectations for the quality of proprietary ESG research that asset managers and consultants can provide to them.

In turn, investors complement external, off-the-shelf research and data analytics with internal, proprietary ESG research.

A

third-party ESG data provider
online platforms.

Whilst these platforms vary in sophistication, they do offer the first composite picture of a portfolio’s stock-specific risks on a number of potential ESG metrics.

Many of these platforms are capable of:

▶ illustrating a portfolio’s mean exposure and weighting towards low-, mid- or high-scoring companies on ESG metrics;

▶ producing a picture of the portfolio’s environmental and carbon exposure on an absolute-value basis (for instance, expressed as weighted-average carbon intensity; and

▶approximating an overall controversy or risk score for the portfolio).

Q

Asset owners and managers increasingly recognise the limitations of third-party ESG platforms, and the need to develop more sophisticated ESG analytics platforms that combine third-party and proprietary capabilities.

The rationale stems not only in the interest of safeguarding portfolio holdings – particularly with regard to clients’ segregated investment mandates – but also in demonstrating a differentiated approach to understanding and reporting portfolio data.

Given the subjectivity and divergence among ESG ratings providers, developing an approach that incorporates both third party and proprietary ESG data lowers an **overreliance to a single provider and creates greater context for discussion when reviewing the risk profile of a portfolio.

A

For example, a portfolio ESG analytics tool employed by an asset manager may aggregate a number of different data streams from ESG providers to produce a picture of ‘consensus’, rankings-oriented ESG scores and their variance alongside an internally-produced ‘proprietary’ ESG score in addition to a view of absolute values- based environmental fund metrics and exposures.

These analytics tools allow investment teams to decompose both their portfolios and benchmark indices, sort by ratings and understand the distribution curves across a number of ESG metrics.

They often provide drill-down capabilities that illustrate a more detailed picture of ESG characteristics on an underlying basis for positions.

Portfolio tools provide investors with the ability to stress test a portfolio against different ESG criteria (such as a sudden, hypothetical increase in the price of carbon emissions) to understand the sensitivity of the portfolio.

This exercise is no different to how current portfolio tools provide the means to stress test portfolios against simulations, such as interest rate or oil shocks.

▶ idiosyncratic exclusions.

Q

Universal exclusions
Universal exclusions represent exclusions supported by global norms and conventions like those from the UN and the World Health Organization (WHO). It could be argued that controversial arms and munitions (cluster munitions and anti-personnel mines), nuclear weapons, tobacco and varying degrees of exposure to coal-based power generation or extraction all qualify as universally accepted given normative support and the growing asset owner AUM they represent.

A

Arms and munitions exclusions
Exclusions governing investment in controversial arms and munitions are supported by multilateral treaties, conventions and national legislation:
Ottawa Treaty (1997), which prohibits the use, stockpiling, production and transfer of anti- personnel mines;
UN Convention on Cluster Munitions (2008), which prohibits the use, stockpiling, production and transfer of cluster munitions;
UN Chemical Weapons Convention (1997), which prohibits the use, stockpiling, production and transfer of chemical weapons;
UN Biological Weapons Convention (1975), which prohibits the use, stockpiling, production and transfer of biological weapons;
Treaty on the Non-Proliferation of Nuclear Weapons (1968), which limits the spread of nuclear weapons to the group of so-called Nuclear-Weapons States (USA, Russia, UK, France and China);
Dutch Act on Financial Supervision ‘Besluit marktmisbruik’ art. 21 a. 3. The Belgian Loi Mahoux, the ban on uranium weapons; and
UN Global Compact announced the decision (2017) to exclude controversial weapons sectors from participating in the initiative.

Tobacco exclusions
Although tobacco does not exhibit the same degree of universal acceptance that the exclusion over controversial arms and munitions does, it provides another example which can be said to be supported by:
WHO Framework Convention (2003) on Tobacco Control with 181 parties committing to implementing a broad range of tobacco control measures;
UN Global Compact (UNGC) announced the decision (2017) to exclude tobacco companies from participating in the initiative, as tobacco products are fundamentally misaligned with UNGC’s commitment to advancing business action towards SDG 3 and in direct conflict with the right to public health;
UN SDGs (2015) drive a collection of 17 global goals to eradicate poverty, protect the planet and improve prosperity; many of the goals touch on tobacco as an impediment to improved social and environmental outcomes.

Q

Mean-variance optimisation (MVO)

MVO results in the construction of an efficient frontier that represents a mix of assets that produces the minimum standard deviation (as a proxy for risk) for the maximum
level of expected return. It is based on defined asset class buckets and long- term expected returns, risks and correlations.

MVO is highly sensitive
to baseline assumptions, making it imperative
to fully understand any revised assumptions due to ESG considerations. MVO is highly dependent on historical data as the baseline with adjustments made to reflect future expectations. Volatility as a proxy for risk does not work well in cases of fat tail risk and large market swings.
ESG issues could impact on assumptions regarding expected return, volatility and correlation at the asset and sub-asset class level. ESG issues also have the potential to expand the regional and asset class mix and to add new sub- asset classes to align with the pursuit of positive real- world impact.

Factor risk allocation

Factor risk frameworks seek to build a diversified portfolio based on
sources of risk. Typically includes factors such as fundamental risks (GDP, interest rates and inflation) as well as market risks (equity risk premium, illiquidity and volatility).
The macroeconomic links to ESG issues are more difficult to quantify with precision from a purely top-down perspective. Market risk factors can be built from the bottom-up using asset and sector level analysis.
ESG issues could require a change to baseline factor risk assumptions. It offers the potential to build
in new ESG-related risk factors (such as climate change) to improve diversification (particularly across market risk factors).

Total portfolio analysis (TPA)

Similar to factor risk allocation, TPA allows for closer review and interplay between the strategy setting process and alignment of investment goals. Based on an
agreed risk budget, asset allocations are made on expected risk exposures and are less constrained by asset class ‘buckets’
as traditional MVO approaches.
TPA is relevant to consider ESG issues that require the interplay between judgment about the future and quantitative analysis. TPA requires specialist knowledge to make informed judgments about future risk.
TPA’s emphasis on risk budgeting and allocation of capital to opportunities within that budget (bringing alignment between top-down
and bottom-up) would provide greater flexibility to capture the potential winners and losers in scenario analysis that also incorporate ESG-related issues.

Dynamic asset allocation (DAA)26

DAA is driven by changes in risk tolerance, typically induced by cumulative performance relative to investment goals or an approaching investment horizon.
DAA could introduce
an additional source of estimation errors due to the need for dynamic rebalancing.
DAA has the potential to reflect changes in baseline assumptions over different time horizons.

A

Liability driven asset allocation

LDI seeks to find the
most efficient asset class mix driven by a fund’s liabilities. Simultaneously concerned with the return of the assets, the change in value of the liabilities, and how assets and liabilities interact to determine the overall portfolio value.
LDI encounters the same limitations as MVO, with high sensitivity to baseline assumptions.
Some ESG issues could potentially impact on inflation and alter liability assumptions.

Regime switching models28
Regime switching approaches model abrupt and persistent changes
in financial variables due to shifts in regulations, policies and other secular changes. Captures fat tails, skewness and time-varying correlations.
Regime switching approaches are relevant for considering ESG issues where an abrupt shift is expected over time. It is also typically based more on forward looking rather than historical data.
These approaches have the potential to capture dramatic shifts in the investment environment. Models are not yet widely utilised by investment practitioners.

Q

Within the asset allocation framework shown in Table 8.4, one of the most promising approaches may well be the Black-Litterman asset allocation model (BLM).

A

While the Markowitz-derived MVO approach has garnered significant academic support, mean variance theory faces a number of limitations. For it to function, MVO råequires estimates for asset returns across each asset class, which makes the model incredibly input-dependent and sensitive. Any adjustments (even minor ones) to these return estimates will produce a dramatic change in allocation output, so investors may find the model hard to practically implement.
By comparison, BLM represents a more intuitive approach. Anchored by the global equilibrium market and not requiring return estimates for each asset class, it can arguably better accommodate areas like pricing climate risk.3

Q

Despite the academic work supporting ESG’s effect on risk-adjusted returns, introducing ESG into the asset allocation process will undoubtedly carry exposure and weighting implications that must be considered relative to a standard, non-ESG asset mix strategy.

In other words, integrating a given ESG methodology (e.g. positive screening that tilts the overall assets mix to a higher than mean ESG rating) will introduce some diversification effect or skewness.

A

To be sure, this effect may well be intended.

In theory, managing a mixed- asset portfolio according to a carbon constraint or desired exposure level should reduce the risk to a carbon pricing shock through lower commensurate exposure to carbon-intensive, coal-reliant utilities and potential stranded assets.

Figure 8.5 illustrates the trade-offs that investors must consider when allocating to ESG or ‘sustainability’ more broadly.

Q

Traditionally, institutional investors have managed systemic, macro-economic factors by coupling asset allocation strategies (SAA) alongside asset/liability management (ALM).

Where strategic asset allocation establishes return targets across asset classes (equities, fixed income, real assets, etc.) and investment strategy types (i.e. alternatives), ALM provides investors the tools with which to match the cash flows of assets to payment of liabilities.

For example, both of these elements are vital for the sustainability of a pension funds’ risk-adjusted returns and its ability to pay out pension benefits for its beneficiaries

ASSET CLASS
Alternative investments

SUBTYPES
• Real estate investment trusts (REITs);
• commodities;
• currencies;
• private equity, venture
capital (VC) funds; and
• derivatives, hedge funds.

SAA/ALM IMPLICATIONS
• Attractive for diversification and for low or inverse correlation to market returns; and
• heterogeneous and wide-ranging risk/return profiles.

CLIMATE CHANGE CONSIDERATIONS
• Diversification offered by alternative assets may allow for greater hedging of climate risk; and
• climate risk exposure may be concentrated, opaque or difficult to assess.

EQUITIES: • Sensitive to climate impacts on macro-economic performance.

FIXED INCOME:
• Sensitive to fiscal policy related to climate challenges;
• sensitive to climate- related impacts on issuers’ creditworthiness; and
• many climate impacts fall within the tenor of long-term debt.

Q

It is also clear that climate change represents different risks across asset classes.

Accordingly, portfolio managers must recognise that a company’s capital structure will naturally reflect risk.

For example, carbon- intensive companies like coal-powered utilities without an adaptation strategy will be at risk in the transition to a low-carbon economy.

In such a scenario, equity shareholders (who are subordinate to creditors and bondholders in the capital structure) will be disproportionately impacted.

Hence, asset allocation strategies must recognise asset class sensitivity alongside systemic and company-specific risks.

A

As well as being one of the key recommendations of the **TCFD framework,

**climate scenario analysis is as important in the wider asset allocation process as it is in understanding the micro, macro and ESG sensitivities within a single investment portfolio.

What might that look like in an asset allocation context?

The asset allocator would work to sensitise the portfolio against different warming scenarios using the 1.5o Celsius (2.7o Fahrenheit) as promoted in the Paris Climate Agreement (2015) as a baseline.

Q

Different scenarios should stress test different asset classes across regions, sectors, time periods and temperature assumptions to understand risks that are now formally characterised as:

A

▶ Physical risks. These represent the physical risks manifested by climate change that may impact businesses’ operations, strategy, infrastructure, workforce or markets; it may carry wider implications across the investment value chain and to the financial system.

▶ Transition risks. These are the risks represented by legal, regulatory, policy, technology and market change in the transition to a low carbon economy. Stranded asset risk, for example, would qualify as a transition risk for a portfolio.

26
Q

It is also worth highlighting new literature that introduces the notion of the Inevitable Policy Response (IPR).

IPR assumes that, in the current environment where the policy response to climate change is inadequate
– perhaps best characterised as “business as usual” – governments may potentially respond to increasing climate-borne damage in a sudden reflex reaction.

A

IPR may take shape through the introduction of economic incentives, such as a carbon tax or the formation
of national carbon markets. It may also include other measures including more stringent environmental regulations requiring greater levels of mitigation-associated capital investment for highly exposed companies.

The nature and magnitude of IPR may carry considerable implications for an investment portfolio, particularly in the speed and scope of transition risk. Hence, the development of more sophisticated approaches designed to understand the sensitivity of an investment portfolio to climate policy-related shocks and simulations are warranted as risk measures.

27
Q

Climate-related portfolio analysis is nascent enough that it is worth highlighting the approaches of two practitioners, Mercer and Ortec Finance. Mercer has continued to refine its climate scenario model, now integrating it into a long-term, strategic asset allocation methodology that extends out to 2100.

Importantly, Mercer’s latest report, Investing in a Time of Climate Change, also addresses the need to enlarge asset allocation models beyond equities. The Mercer report formally extends its climate-informed asset allocation process to

sustainability-themed equity,
private equity and
real assets, including
natural resources and infrastructure.

A

Climate change modelling
and literature review

The modelling foundations
are provided by a third-party macroeconomic model, E3ME, which draws upon the “GENIE” integrated assessment model (IAM). IAMs combine climate science and economic data to estimate the costs of mitigation, adaptation and physical damages.

Risk factors and scenarios
Three climate change scenarios provide a framework for the relative impacts for identified climate change risk factors over time.

Asset sensitivity
The sensitivity to the climate change risk factors is determined for different asset classes and industry sectors.

Portfolio implications
The sensitivity and scenarios are integrated into Mercer’s investment modelling tool
to estimate the impact of climate change on investment portfolio returns.

Ortec Finance’s

approach integrates climate risks into financial scenarios, which include transition, physical and extreme weather impacts and pricing dynamics to cover all asset classes.

For example, Figure 8.7 illustrates the impact on a representative UK pension fund portfolio over two different investment horizons and against three simulations—Orderly, Disorderly and Failed—calibrated against the Paris Agreement.

A

In the nearer-term simulation (2020–2024), climate transition risks point to lower expected investment returns relative to the Paris-aligned pathways (Orderly and Disorderly).

While a Paris Orderly Transition gradually prices in lower earnings expectations across the 2020-2024 period, a Paris Disorderly Transition represents an earnings correction that produces a shock in 2024 and higher subsequent volatility.

In the later-term simulation (2025–2029), the average investment return in an orderly transition is similar to the climate-uninformed baseline where transition risk and physical risks are not modelled. In contrast, both the Paris Disorderly and Failed Transitions point to lower expected investment returns.

In the Paris Disorderly Transition pathway, the sentiment shock occurring in 2025 and subsequent increase in volatility remain until 2026.

The Paris Failed Transition pathway – characterising a business-as-usual-scenario that brings about a 4oC (5.4oF) temperature increase by 2100 – leads to diminishing investment returns as the impact of physical risk increases.

The portfolio impact of physical risk expected leads to diminishing investment returns over this period.

Q

Integrating ESG into manager selection

Within the wider asset allocation process, it is also worth highlighting that allocators are increasingly integrating ESG factors and expectations into their manager selection process.

The allocators range from traditional asset owners, such as pension funds to fund of fund (FoF) and multi-manager investment strategies.

Rather than investing directly into securities and issuers, multi-manager strategies focus on building a platform of strong individual fund managers. These platforms may either focus on internally-managed funds from the same investment firm or funds managed by external managers as well.

A

Due diligence in regard to manager selection combines qualitative and quantitative metrics that, within a framework, track the development, performance and improvement of managers.

Many of the larger multi- manager and fund of funds platforms typically track, monitor and assess between a hundred and several hundred individual portfolio managers.

These multi-manager platforms then review this long list of tracked managers in order to reduce this list to a short list or watch list, ultimately tightening this to a final focus list of managers to allocate capital. In this respect, due diligence focuses on establishing baseline metrics to valuate and compare managers.

30
Q

Metrics may include:

A

» the existence of an ESG policy;
» affiliation with investor initiatives such as the PRI;
» accountability in the form of dedicated personnel and committee oversight;
» the manner and degree in which ESG is integrated in the investment process;
» ownership and stewardship activities; and
» client reporting capabilities.

31
Q

Figure 8.8 depicts an example of a high-level manager selection process, in this case developed by BlackRock Alternative Advisors (BAA).

A
  1. SOURCING:
  • Maintain a veiw on “best practices” demonstrated by market leaders in the hedge fund space
  • Seek to identify market leaders (i.e. managers incorporating ESG considerations in a thoughtful and material way) within each individual hedge fund strategy peer group
  1. EVALUATION
    • Include ESG questions within its qualitative evaluation of a hedge fund manager during the initial meeting
    • Assess key areas of ESG integration as it pertains to a manager’s:
    – Investment philosophy
    – Investment strategy
    – Investment process – Team structure
  2. APPROVAL
    • Proprietary ESG scoring included in the manager tear sheet and reviewed by Manager Approval Group (MAG)
    • ESG considerations noted in due dilligence check list
    • ESG policy reviewed
    • Will not invest if the MAG determines
    that a material and relevant ESG risk cannot be sufficiently understood or qualified
  3. ONGOING MONITORING
    Research maintains an ESG score based on ongoing reviews
    • Risk team coordinates with relevant BlackRock teams to evaluate funds relative to various ESG criteria
    • Operational Due Diligence requests updates on the ESG policy & approach in its quarterly monitoring process
    • ESG considerations added to BAA’s qualitative heat map.
32
Q

As a whole, the due diligence process offers a more nuanced perspective into the degree of ESG integration and the investment approach adopted.

A formal monitoring and reporting framework also provides a picture into the progress and evolution of a manager’s ESG capabilities and resourcing.

While much of this process naturally focuses on investment facing capabilities, from ESG data integration to dedicated investment strategies – due diligence also commonly assesses operational risk of the investment manager, itself.

A

The operational risk portion of manager due diligence may examine what organisational framework and oversight exist at the firm level to support ESG activities at the fund level.

Has the manager instituted ESG and/or stewardship policies?

What compliance measures are in place to ensure that exclusion-oriented and/or ESG constraint-based investment mandates and strategies are observed?

And, because of growing regulatory requirements, they may also include examining the sophistication of ESG and climate risk reporting.

33
Q

Accordingly, multi-manager and fund of fund platforms are

increasingly integrating their own ESG capabilities into more formal scoring frameworks.

A

▶For some platforms, these frameworks represent a spectrum of capabilities across different strategies.

▶For more sophisticated platforms, these frameworks have gone beyond simply informing the manager selection process to now acting as a formal factor or weight in the overall manager selection and allocation process.

APPLYING ESG SCREENING INVESTMENT STRATEGIES WITHIN PORTFOLIOS AND ACROSS ASSET CLASSES

A

ESG screens across asset classes

The growth in third-party ESG datasets has driven a need for both innovation and differentiation across asset classes.

The emergence and diversity of ESG-oriented indices and benchmarking approaches is a clear proxy for this growth.

First originating with a heavy focus on equities, indices have quickly extended into other asset classes.

35
Q

This drive has been shaped by investor appetite as well as regulatory considerations in an effort to create a more uniform taxonomy of definitions in green bonds.

By almost all metrics, ESG integration continues to grow across asset classes as well as regions.

A

As shown in Figure 8.10, some investor types are clearly making greater progress than others.

That said, it is important to recognise that some asset classes and strategies face greater challenges than others.

This may be because of the lack of quality datasets in some markets, particularly for some private markets, where equities and corporate credit have benefited the most from greater data availability and applications.

It may also have to do with the slow formation of best practices for some alternative approaches.

There are active working groups in a variety of hedge fund investor initiatives including the PRI, the Alternative Investment Management Association (AIMA) and the Standards Board for Alternative Investments (SBAI),

but they have produced measurably less in terms of discussion papers and guides for ESG integration relative to other areas.

36
Q

Fixed income (government, sovereign, corporate and other)

Generally speaking, ESG integration in fixed income has experienced a good deal of catch up relative to listed equities.

A

However, there is still significant differentiation across the sub-asset classes.

In Figure 8.11, Mercer’s ratings for ESG integration within credit subclasses reveal a greater number of higher ratings – ESG1 and ESG2 –

in investment grade credit, emerging markets debt and buy-and-maintain strategies while government debt and high yield credit experience lower degrees of integrations.

As we will discuss, lower levels of ESG integration in areas like sovereign debt and high yield credit often reflect a **scarcity in ESG ratings and data sets and ratings, particularly in the ***unlisted credit markets.

37
Q

Corporate debt
Corporate debt is now enjoying greater levels of ESG integration. In some regards, this should not be surprising. Issuers of equity also tend to issue debt. Indeed, there is growing evidence of ESG-incorporated methodologies yielding meaningful performance differentials. First, it is worth briefly highlighting why debt is distinct from equities. The debt issued by a single corporate – or sovereign for that matter – often represents multiple credit risk profiles across bond issuances. These bond issuances represent different maturities, which refer to the payment date of a loan. In contrast, corporates issuing equity generally issue one common share class.iii The temporal dimension across multiple debt maturities and credit risk profiles arguably lends itself to a more granular comprehension of ESG issues and their materiality. For example, one method available to a credit portfolio manager seeking to manage the long-term climate risk effects of an issuer is to invest in the issuer’s shorter-dated maturing debt.

A

Figure 8.12 illustrates examples of two investment-grade bonds with an ESG tilt applied. Although the short times (August 2009 to April 2016) limit the ability to make a strong performance claim across multiple economic cycles, both bond portfolios suggest that high ESG portfolios outperform low ESG portfolios despite being driven by different ESG methodologies. However, it is important to bear in mind that after the global financial crisis of 2008-09, ‘quality’ as a factor outperformed while ‘value’ largely underperformed. Given the strong correlation between high ESG and ‘quality’ among ESG vendors, it is important to note that the ESG-driven performance returns are not necessarily causal.

▶The Fundamental ESG Risk Metric examines fundamental ESG risk at the issuer level.

▶The Investment ESG Score operates at the bond level, allowing for different credit risk sensitivity resulting from the ESG risks as a function of the bond features.

The ESG Score is unique in that it examines ESG both as risk and as opportunity within the overall score.

While useful at the issuer level, its value and differentiation for both its internal investment teams and investors lies in elevating the picture of ESG risk from the individual bond to the single issuer level, and ultimately understanding ESG risk within a given credit portfolio.

39
Q

ESG bond types

New forms of credit issuance have emerged, designed to raise funding to deliver social and environmental objectives alongside a financial return.

With the World Bank often playing a leading role in developing these markets and advising bond issuers, ESG-oriented bonds are typically organised around a few sustainable themes.

What distinguishes these from conventional bonds is their underlying use of proceeds and the greater transparency they provide towards their use of proceeds.

Investors include both asset managers and asset owners who may see these bonds as a way to advance sustainable finance as well as a means to diversify their asset mix.

A

Despite the development of ESG in fixed income, the absence of a universally recognised standards certification system for sustainable bonds should be recognised.

A number of standards have emerged, notably the ***European Union’s (EU) proposal for an EU green bond standard.

However, the absence of a universal standard is particularly urgent given the emergence of bond issues geared towards underlying sustainable themes, as shown in Table 8.6.

For instance, despite the green bond market emerging little more than a decade ago, labelled green bond issuance has ****increased by roughly 50% in the first half of 2019 to US$118bn (£91bn),

of which 19% represented certified climate bonds.

40
Q

Ooooo BOND TYPES

          ************Green bonds************ Green bonds are any type of bond instrument that funds projects that provide a clear benefit to the environment, such as renewable energy projects. 

Originating in 2007 with the issuance of the first green bonds from the European Investment Bank (EIB) and the World Bank, some green bond indices now track the development of issuance and offer investors a passive means of investing in green bonds.

Benchmark indices include:
• S&P Green Bond Select Index;
• Bank of America Merrill Lynch Green Bond Index; and
• the Bloomberg Barclays MSCI Green Bond Index.

              ************Social bonds************

Social bonds fund projects that provide access to essential services, infrastructure and social programmes to underserved people and communities.

Examples include projects providing:
• affordable housing;
• microfinance lending;
• healthcare; and
• education.

The Spanish Instituto de Credito issued the first social bond in 2015.

A

**Sustainable bonds**

Sustainable bonds offer issuers more broadly defined bonds that still create a positive social or environmental impact.

***In 2016, Starbucks issued the first US corporate sustainability bond of US$500m (£385m) that directly links the company’s coffee sourcing supply chain to ESG criteria.

              ************Blue bonds************

Blue bonds fund projects with clear marine and ocean-based benefits, such as sustainable fishing projects. The Seychelles and the World Bank jointly issued the first blue bond in 2018.

41
Q

**Sovereign debt***

ESG integration approaches that lend themselves well to equities and corporate debt run into a number of difficulties when applied to sovereign debt.

The number of governments issuing bonds, or sovereign debt, represent a much smaller investable universe than the number of corporates who issue corporate debt.

Should their credit profile be strong enough, any listed corporate could issue some form of credit, from investment grade to high yield.

Whilst there is no limit to the creation of new corporate entities that issue fixed income, the pool of governments that issue debt is small by comparison, and essentially finite.

A

By extension, the exclusion of countries (whether in the form of multilateral sanctions or economics sanctions limiting foreign direct investment (FDI))

will further reduce this pool and diversification potential.

For instance, US sanctions on Russia following its 2014 annexation of Crimea extended to Russian sovereign debt. US sanctions **effectively limited any participant in the US financial system from financing or dealing in debt of longer than 90 days maturity.

More recently, in 2019, the US government imposed sanctions on transactions tied to Venezuela, severely diminishing the trading liquidity of Venezuela’s secondary sovereign debt.

Credit rating agencies (CRAs) represent an important component for sovereign debt investors, and should be leveraged at both the issuer and the portfolio levels.

Research already points to a high correlation among CRA ratings, as well as between CRA ratings and sovereign yields. This is quite different relative to the ESG ratings which suffer with low correlation among ratings providers.

Fortunately, investors benefit from a growing pool of sovereign investment research resources.

Not surprisingly, many of these resources focus on governance.

Many ESG-focused sovereign debt investors begin by building and integrating an ESG framework based on the World Bank’s World Governance Indicators.

This World Bank dataset considers:

▶ a country’s governance score; and
▶ its rankings on:

» political stability;
» voice and accountability;
» government effectiveness;
» rule of law;
» regulatory quality; and
» control of corruption.

Although the World Bank data is slow-moving, it offers a near 20-year time series and a means for investors to identify improving or deteriorating trends across these metrics.

Investors can, in turn, examine either on a per sovereign basis or, as illustrated in Figure 8.14 with

**four of the six World Bank indicators,

reflect on the change in momentum in the context of a portfolio holding many sovereign debt positions.

43
Q

WGI

WORLD GOVERNANCE INDICATORS

A

ESG tools are increasingly more sophisticated in leveraging data sets like the World Bank’s WGI to draw out correlations between economic data.

Like equities, sovereign debt is just as susceptible to distortion effects based on ESG ratings.

These will be most notable in strategies that trade in both developed and emerging economies; ESG ratings and indicators like those of the World Bank tend to be structurally lower for emerging countries relative to developed economies, which enjoy higher standards of transparency, rule of law, regulatory authority and anti-corruption.

For instance, an emerging markets debt portfolio will benefit from a higher ESG score if it is underweight with emerging markets and overweight with defensive positions, like US treasuries or German bunds. Hence, it is critical to understand that this developed-emerging weighting is driving the overall ESG score.

44
Q

Ultimately investors should aim to embed ESG within their overall process, effectively normalising it alongside other risk factor criteria. Figure 8.16 shows an example where a Z-scored ESG indicator, reflecting a composite of World Bank governance data and JP Morgan ESG data, sits as one of the active inputs with a portfolio’s sovereign scoring tool.vi

A

The JP Morgan ESG suite of indices is a global fixed income index family which integrates environmental, social and governance factors in a composite benchmark. The ESG JPM index applies a multidimensional approach to ESG investing for fixed income investors. It incorporates ESG score integration, positive screening as well as exclusions of controversial sectors and UN Global Compact violators. ESG JPM Index Scores are calculated daily, using data from RepRisk, Sustainalytics and Climate Bonds Initiative (CBI) as inputs.

46
Q

Equities (listed or private)
Listed equities

Listed equities represent the most developed asset class in terms of ESG integration.

Equities has various advantages relative to other asset classes, notably the greatest amount of
*** transparency owing to its capital structure where creditors and shareholders coexist, albeit in a relationship that subordinates shareholders.

The listed nature of equities and their ownership structure provides shareholders with the ability to exercise their view through their voting rights on many aspects of operational and strategic direction of the company,

Including its board of directors. Shareholder rights and voting are one of the most prominent manifestations of stewardship where investors increasingly address non-financial objectives alongside financial issues.

Because of the enhanced nature of ESG disclosure among listed equities, all of the responsible investment strategies discussed in this chapter lend themselves to the asset class.

This ranges not only from passive to active investment strategies, but from long-only to hedge funds as well. For that reason, this section will not restate the nature and mechanics of those investment strategies.

A

Private equity

Like unlisted credit and real asset private markets, ESG integration in private equity faces several challenges, foremost being the lack of public transparency, established reporting standards, regulatory oversight and public market expectations around ESG.

The lack of compulsory non-financial reporting regulations like the European Commission’s Non-Financial Reporting Directive (**NFRD) for large European companies severely limits a
***private equity portfolio manager’s ability to leverage ESG data for relative ranking and scoring comparability.

In addition, smaller, private companies are often capacity-challenged by ESG reporting requirements.

The quality, consistency and continuity of strong integrated reports published by many public companies represents a high hurdle to achieve for smaller companies.

Early-stage companies also tend to operate with a much greater degree of freedom than more mature, listed companies.

As a consequence, the portfolio manager will have to weigh the company’s ESG trajectory (it may have established, but not yet met, ESG objectives) against the trajectories of more mature companies. This extends not only to the way the business or asset operates, but also to the board level-devised strategy.

In some cases, private equity investors must negotiate against a strong founder or founder team which, while a powerful internal motivator, may present long-term governance concerns.

At the same time, early investors and significant shareholders are often strategic and long-term oriented, creating a powerful incentive to establish a strong set of ESG KPIs early in the company’s life cycle.

It may be in the interest of the general partners (GPs) to set up specific, portfolio-wide metrics (obviously recognising geographic and sectoral differences) as a means to support the overall portfolio strategy and communicate portfolio alignment to the fund’s limited partner (LP) investors.

Table 8.7 illustrates several ESG metrics tracked across different industries for several funds to gain a static, high-level picture of exposure.

47
Q

REAL ESTATE

Real assets: real estate and infrastructure

Real assets like real estate and infrastructure carry certain advantages and challenges compared to the equities and corporate fixed income investment universe.

In many cases, investors are majority owners or own the asset outright. Majority or full ownership stakes offer investors much greater control over the definition, application and reporting of ESG data alongside or outside existing reporting standards like that of the Global Reporting Initiative (GRI).

Much like corporate unlisted fixed income, managing a portfolio of real assets requires building a picture of what the aggregate risk looks like as well as the correlation risk among all the underlying assets.

GRESB’s full benchmark report (Figure 8.17) provides a composite of:

▶ peer group information;
▶ overall portfolio KPI performance;
▶ aggregate environmental data in terms of usage and efficiency gains;
▶ a GRESB score that weights management, policy and disclosure;
▶ risks and opportunities, monitoring and environmental management system (EMS);
▶ environmental impact reduction targets; and
▶ data validation and assurance.

Nonetheless, this report depends heavily on companies, funds and assets participating in the GRESB reporting assessment process. For portfolios where a significant percentage of the fund’s holdings do not participate in the GRESB assessment, portfolio managers will need to supplement with their own ESG scoring.

A

Green Risk Premium

48
Q

Traditional residential housing model delivery had little regard for ESG factors. The primary model of delivery was concrete based, with inefficiencies among other building materials. Not surprisingly, the sector had
a significant carbon footprint focused primarily on environmental criteria on a short-term, new build and construction basis.

ESG and impact-oriented residential strategies now focus on much broader criteria, actively integrating all components – particularly social considerations – within their portfolio.

Besides reducing the carbon footprint of their housing stock through more efficient building materials, community housing strategies now make efforts to deliver affordable mixed tenure housing solutions that provide greater social segmentation to meet the needs of the community – young people, first-time buyers, key workers and seniors.

Investors with significant real estate exposure are increasingly leveraging the analytical modelling capabilities and historical datasets of insurance companies to understand weather risk generally and climate risk more specifically.

A

A joint study by Munich Re and PGGM, the Dutch pension fund, applies these analytics on PGGM’s private real estate portfolio.

A climate risk profile based on over 100 years of meteorological, weather and hazardous-event data, is capable of examining the climate risk of a diversified, global property portfolio across different dimensions, from overall hazard risk factor exposure to country and city (Table 8.9), and ultimately down to individual property level risk.

Capabilities now enable an extremely nuanced understanding of exact longitudinal and latitudinal data.

49
Q

Munich Re, one of the world’s largest reinsurers, produces climate risk assessments that model potential property impact scenarios based on a broader set of twelve natural hazard types, including:

earthquakes; 
volcanic eruptions,
▶ ▶ ▶ ▶ ▶ ▶ ▶ ▶ ▶ ▶
Table 8.9:
tsunami;
tropical cyclones; extratropical storms; hail;
tornadoes; lightning;
wildfires;
river floods;
flash floods; and storm surges.
A

With growing evidence of sea-level rises capable of impacting population-dense coastal areas and communities,

investors may also enhance the climate rate analysis of their portfolios by profiling a portfolio’s exposure to elevation and coastline proximity (Figure 8.18).

The effects of coastal erosion and flooding ultimately leading to managed retreats could carry meaningful consequences to property values and insurance premiums. Indeed,

a study already indicates that residential properties in the USA located in areas exposed to sea-level rises already reflect a 7% discount relative to unexposed, nearby homes.

50
Q

Integrating ESG screens within portfolios to manage risk and
generate returns

The effects and benefits of integrating ESG into portfolio management are an increasingly wide area of study.

Investors typically address the effects to risk-adjusted returns of ESG integration in portfolio management through two dimensions:

▶ risk mitigation; and
▶ alpha generation.

Integrating ESG to manage portfolio risk
Risk mitigation is the exercise of assessing and minimising the exposure of a portfolio to ESG risks.

Sometimes, these risks are often referred to as tail risks. In an ESG context, tail risks are generally long-term in nature and describe a significant change or move by several standard deviations in the risk profile of an asset.

Depending on the position size in a portfolio, the potential volatility of such an asset may carry significant implications for the portfolio’s overall risk profile and to its potential risk-adjusted returns.

For example, a real estate portfolio that is heavily invested in beachfront property at risk of coastal retreat should actively assess the potential impact to the portfolio’s risk-adjusted returns, and consider mitigating or minimising its exposure.

In another example, a portfolio with significant holdings in the European utilities sector should routinely assess its exposure to understand its short-term risk to carbon price volatility and, in the long term, to a potential stranded asset write-down risk.

Much scrutiny is required when linking correlation between ESG integration and investment returns. Fundamentally, any strong claim regarding ESG-driven performance requires a robust means to measure ESG. While firms may have certainly developed proprietary approaches to this problem, the ability to measure performance attribution for ESG does not commercially exist.

A

To this end, it is worth a short review of some general theory about risk within portfolio management and where ESG fits into the discussion.

Financial risk in the traditional sense is generally expressed as a number. This number could assume many different forms:

▶ a variance;
▶ volatility; or
▶ value-at-risk (VAR)

51
Q

Over the last half decade, numerous approaches have emerged to measure and price risk.

CAPM

The capital asset pricing model (CAPM) measures the proportional risk of a security or portfolio relative to market risk in the form of a premium.

A

More recently, Eugene Fama and Kenneth French introduced three-factor and, subsequently, five-factor models, which both describe how certain risk premia

(investment risk, market risk, size risk, profitability
risk and value risk)

are able to explain the probability distribution of investment returns.

Well-established evidence for these risk premia – the differential between market returns and the risk-free rate, or the differential between high- and low-valued companies on a price-to-book basis – exists, not only to drive factor- oriented investment strategies, but also to enhance risk factor portfolio attribution.

In short, these efforts have contributed to the manner in which financial markets can identify, assign and manage risk for single assets as well as portfolios.

52
Q

Risk also appears as either idiosyncratic or systematic risk:

A

▶ Idiosyncratic risk describes firm- or stock-specific risk. In an ESG context, idiosyncratic risk could be posed
by a company’s staggered board of directors or a mining company that is repeatedly fined for its untreated mine tailings. In order to reduce or mitigate this kind of idiosyncratic risk, a portfolio manager may diversify the portfolio, diluting the exposure to the mining company. The portfolio manager may instead simply exit the poor-performing company outright, eliminating the risk.

▶ Systematic risk represents market risk, such as economic recession, that cannot be resolved through portfolio diversification, alone.

53
Q

Studies demonstrating that almost 80% of alpha (returns in excess of market performance) can be attributed to

portfolio factor risk

rather than stock-specific risk, would seem to support research efforts to identify and define ESG as a standalone factor.

A

Despite the growing sophistication in ESG analysis across different asset classes and investment strategies, ESG is still largely characterised by its process-oriented approach for much of the investment management industry. This remains distinct from traditional approaches to risk which, although reductive in nature, are also quantitative and generalisable. Moreover, treating ESG within portfolio management solely as a process turns it into a qualitative exercise that is subjective and difficult to measure.

This not only increases the potential risk of greenwashing, but it deprives asset allocators the power of attributional analysis. It also means that, outside of absolute value-based metrics like weighted-average carbon intensity, subjective ESG scores and rankings will continue to represent the prevailing means to approximate ESG risk in a portfolio.

55
Q

one of the challenges that remains is how to measure ESG-attributed performance – not just risk – at a portfolio level.

A

Generally speaking, institutional investors apply two popular approaches towards decomposing performance attribution:

Brinson attribution and

risk factor attribution.

Brinson attribution decomposes performance returns based on a portfolio’s active weights. For a given time series, this generally represents performance returns attributed to regional, sector and stock-specific exposure.

Attribution models serve to quantify and demonstrate the effects of asset allocation and selection decisions on investment returns.

56
Q

Quantitative strategies shape and direct the portfolio
in aggregate or on a top-down basis rather than an individual issuer or asset basis.

A more sophisticated approach directly embeds ESG into the algorithmic model, driving the stock selection for the portfolio.

In effect, ESG operates much like any other factor within a multi-factor algorithmic investment strategy.

A

Quantitative managers build proprietary multi-factor models often based on a combination of well- established factors and more idiosyncratic factors. Each factor is prescribed an individual weight which in turn proportionally drives the multi-factor signal.

One of the advantages of a multi-factor model over a smart beta or beta plus strategy is diversification. Factors that are negatively correlated to one another are combined to produce greater portfolio protection against a potential reversal by any one given factor.

57
Q

illustrates the ESG ratings coverage gap of a high-yield credit portfolio where roughly 25% of the strategy’s positions are unrated.

Again, this coverage gap may be due to a number of reasons:

the corporate bond issuer may be too small for ESG ratings providers to score; the bond may be a new issuer that has not yet been scored;
or
it may be unlisted debt.

Regardless of the reason, it is an important example for why and how multiple ESG data sources should be considered when assessing the ESG exposure profile of a portfolio.

Noting coverage gaps when reporting to the investors of a portfolio is not only informationally helpful, but it preserves the integrity of the ESG screening process.

That said, no best practice currently exists in terms of how to treat ESG coverage gaps within a portfolio. However, there are two potential approaches to address this issue:

  1. The simplest approach is to simply rescale the scoreable portion of the portfolio to 100% by proportionally resizing each scoreable position.
  2. The second approach is to apply Bayesian inference to the coverage ratio, effectively grossing it up to 100% by probabilistic inference.

Note that both approaches are reasonable with coverage gaps of up to 25%. Although no hard rule or best practice exists, normalising for a gap in excess of 25% should be reviewed for whether it over- or under- represents a portfolio’s true ESG exposure. This potentially undermines the integrity of ESG analysis at the portfolio level for the manager and may misrepresent the ESG exposure of the portfolio to the fund’s investors.

illustrates the ESG ratings coverage gap of a high-yield credit portfolio where roughly 25% of the strategy’s positions are unrated.

Again, this coverage gap may be due to a number of reasons:

the corporate bond issuer may be too small for ESG ratings providers to score; the bond may be a new issuer that has not yet been scored;
or
it may be unlisted debt.

“sustainable investment” by Morningstar. The sustainable investment label indicates if the fund has prospectus language that explicitly calls out its focus on:
▶ sustainability;
▶ impact; or
▶ specific environmental, social and/or governance factors in its investment process.

Full ESG integration enlarges the scope of ESG analysis beyond the focus of risk mitigation. It recognises that

Q

For these reasons, full ESG integration strategies often take greater efforts to:

A

evidence internal and external research resources;
document how ESG is embedded, typically in a process slide;

track and report on engagement activities with company management;

include portfolio exposure and weightings into sustainability themes like the SDGs;

provide positive impact measurements of the portfolio against metrics like resource efficiency, water and energy consumption;

and
support the process with investment case studies.

Q

Passive investing approaches have evolved from the replication of established indices like the S&P500 or FTSE to more sophisticated strategies. Because of the ease of use and low cost, exclusions-oriented responsible investment approaches were early adopters of passive investing:
beginning with the MSCI KLD 400 Social Index;
graduating to more mainstream indices like the Dow Jones Sustainability Index; and now expanding to other asset classes and strategy types.

A

Investors’ willingness to deviate from the core index based on ESG and sector or security exclusions criteria will determine the degree of differential in tracking error.
