Environmental Factors Flashcards
How are the study of economics and environmental sustainability linked?
Both consider the trade-offs between present costs and future benefits i.e. the depletion of resources, especially those that are scarce such as natural resources.
According to the Stockholm Resilience Center 4 of the 9 planetary boundaries have been crossed, name them?
1) Climate Change
2) Loss of Biosphere Integrity
3) Land-system change
4) Altered Biogeochemical cycles ( phosphorous and NO2 loading aka ferts)
Other 5 include:
5) Ocean acidification
6) Chemical pollution
7) Freshwater withdrawals
8) Ozone layer depletion
9) Air pollution
Primary E factors relevant to how investors assess risks and opportunities?
A) climate change
B) pressures on natural resources
C) Pollution and waste
Define Climate Change (CC) and name 5 of its primary dimensions:
Defined as the change of climate directly or indirectly attributed to human activity, that alters the composition of the global atmosphere. Includes:
- Science
- Economics
- Society
- Politics
- Moral and ethical questions
What is the primary contributor to the warming effect on the planet?
Rising emissions of GHG’s - primarily CO2 (Two thirds) - most of which comes from Fossil fuels.
Other important GHGs include methane, N02, and other fluorinated gasses.
Potential tipping points - regardless of a decrease in energy emissions?
1) melting of permafrost in Northern Hemisphere
2) disintegration of the west Antarctic ice sheet
3) dying of Amazon rainforest
4) melting arctic changes water currents
Caveats of Economic Cost Models of CC?
1) Standard cost benefit analysis is inadequate to deal with catastrophic circumstances aka Dismal Theorem and discounting is hard to quantify
2) Many economic models fail to model sharp discontinuities and instead assume gradual negative impacts
Climate Mitigation and Adaptation Strategies for governments/economies/companies?
1) Deploying renewables i.e. wind, power, solar
2) Retrofitting buildings to be more energy efficient and using materials that reduce carbon footprint
3) Sustainable transportation and infrastructure
4) Reducing deforestation
5) Better land mgmt for crops/grazing
6) Carbon reduction policies that penalize heavy emitters
7) Develop more energy efficient processes as well as equipment for carbon capture, power storage, etc.
What does the UN Emissions Gap Report 2020 state?
That we are currently heading for world temp increase of 3.2 degrees C warmer by the end of this century even with full implementation of unconditional nationally determined contributions (NDCs) under the Paris agreement.
Fun fact: Covid pandemic induced largest recorded emissions drop ever of 7%. Estimated that we need this to occur each year to 2030 in order to achieve the 1.5 degree C target.
What is climate adaptation?
Adapting to a changing climate or expected future climate events thereby increasing society’s resiliency and reducing vulnerabilities
Examples include: Building flood defenses, drought resilient crops, clean cooling systems
Added Context:
Frontline of adaption are cities and municipalities due to high concentration of people, assets and economic activities. At the same time cities are a major contributor of GHG emissions because of transport and buildings.
Global commission of Adaptation claims a $2 Tn investment will yield $7Tn in avoided costs and benefits.
Name the natural resources and the causes of increasing pressures on them?
Land, biodiversity, forestry, marine resources, and non renewable commodities such as fossil fuels, minerals, and metals.
Increased pressure caused by
- population growth
- health improvement
- economic growth
- increased consumption from all type of economies
Primary land usage issues in modern society?
1) modern agriculture is dependent on phosphorus rock which is non renewable. Global reserves may be depleted in 50-100 years.
2) world is currently using half of its vegetated land for agriculture
3) issues compounded by changes in lifestyle including a global affluent middle class, increased use of rare earths and minerals for products like smart phones, higher standards of living, increasing meat and dairy consumption
What kinds of effects does technological innovation have on natural resources?
in short term there is a decoupling effect of increasing economic activity and use of resources but long term this decoupling is merely altered and not reduced.
Prime example is EV market - less gas, more precious metals
This is theorized in the Jevons Paradox
How is water demand interconnected in a way other resources are not?
Only 2.5% of water is freshwater and is used not only for human consumption for for a range of industries including agri, energy, manufacturing as well as recreational and environmental.
2 Billion people experience high water stress, 4 Billion experience severe water scarcity one month of the year.
Biodiversity underpins what ecosystem services? What is the term for this?
Natural Capital is defined as the world’s stock of natural assets including: geology, soil, water, air and all living things . Together they provide a wide range of things for humans.
- Food
- Clean water
- Genetic resources
- Flood protection
- Nutrient cycling
- Climate regulation
Companies with exposure to deforestation in their supply chain face what kinds of risks?
- Supply disruptions
- Cost volatility
- Reputational damage
What are some of the largest issues caused by air pollution?
1) Environmental effects
2) impacts human health- 1/10th of all deaths each year with greatest mortality in regions with substantial fossil fuel related PM ( particulate matter)
3) destroys ecosystems
4) impoverishes biodiversity
5) reduces crop harvests because of soil acidification
What are the 3 principles of the circular economy?
1) Design out waste and pollution
2) Keep products and materials in use
3) Regenerate natural systems
Difference between physical and transitional risks? What are some aspects of Transitional Risks?
Physical risks stem from inaction on CC whereas risks and trade-offs associated with climate action are called transitional risks.
This is acute for energy companies - If govt policies changed in line with Paris Agreement than 2/3rd of worlds known fossil fuels could not be burned and would lead to massive change in value of these assets affecting banks and insurance companies as well as companies that depend on these types of resources such as car makers, plane builders and manufacturers of steel and cement, etc.
Transition risks can be broken down into
Policy Risks
Legal Risks
Technology Risks
