Q

Tools and approaches for assessing social conditions

Page 3

A
  • Single site: Environmental Impact Assessment (EIA) and Social Impact Assessment (SIA) –> process within establishment and facility/plant/site within establishment
  • Enterprise: CSR type 1 and type 2 –> facility/plant/site within establishment and enterprise/management
  • Enterprise and a limited part of the supply chain: CSR type 3 –> facility/plant/site within establishment and enterprise/management
  • Product life cycle: E-LCA and S-LCA –> process within establishment and facility/plant/site within establishment

Q

Why should the social dimension be considered?

A

Renewable materials reduce Co2 emissions and economic costs, but can potentially increase social risks.

Q

S-LCA Guidelines

A
  • UNEP/SETAC Task Force on S-LCA:
    • under development to make it more practical
    • positive and negative socio-economic and social impacts considered
  • Social Life Cycle Metrics for Chemical Products - WBCSD
    • developed by key players of chemical sector
    • guide for chemical users through S-LCA
  • Round Table of Product Social Metrics
    • developed by companies
    • upgraded to include small scale entrepreneurs + more consistent performance indicators; qualitative impact assessment instead of quantitative

Q

Well-being definition

A
  • concept or abstraction used to refer to whatever is assessed in an evaluation of a person’s life, situation or “being”

Q

Roundtable of Product Social Metrics

A

A group of companies sit together and decide to develop a methodology for assessing social impact of a product along its life cycle.

They match the current literature with the companies´strategy to develop a feasible set of indicators.

Q

Social Hotspot Database and PSILCA

A

Database provides secondary data for social life cycle, hotspot or risk assessments.

Social Databases are based on Global Trade Input Output ” models → provide insights in industries and production processes of sectors and countries

Q

Challenges in S-LCA

A
  • Global supply chains normally include different suppliers and sub-suppliers
  • Database often lacking secondary data for different sectors, countries, products
  • Social issues/aspects are hardly covered by databases

Q

E-LCA & S-LCA

Similarities

A
  • …are based on the ISO framework
  • …iterative procedures;
  • …provide information for decision-making;
  • …do not have the purpose to provide information on whether or not a product should be produced;
  • …conduct hotspots assessments;
  • …huge need for data;
  • …request peer review when communication to the public or comparative assertions are planned;

Q

E-LCA & S-LCA

Differences

A
  • E-LCA does not provide all the information needed to make decisions in a sustainability perspective.
  • S-LCA provides complementary information by addressing social aspects leading to a more comprehensive understanding of the product’s life cycle impacts.
  • E-LCA assesses potential environmental impacts; S-LCA assesses social and socio-economic impacts
  • E-LCA collects information on physical quantities related to the product and its production/use and disposal, S-LCA collects additional information on organization related aspects along the LC

E-LCA analyzes impacts from a global perspective,
S-LCA analyzes impacts locally.

17
Q

E-LCA vs S-LCA - Structure

A

Stakeholder inclusion:
−E-LCA encourages involvement of stakeholders in the peer review of the study,
−S-LCA encourages that “external” stakeholders be involved in providing input on impacts, within the assessment itself.

• Relevant environmental / social issues to be considered in the case addressed have to be defined in Goal and Scope
−ELCA: defined impacts categories exist, are usually used in the studies
−S-LCA: 31 subcategories proposed, but yet not really field-tested −>Subcategories are classified both by stakeholder categories and by impact categories in S-LCA. InLCA they are classified only by impacts categories.

• Impact assessment: No LCA-LCIA method is site-specific. S-LCA often requires site-specific LCIA, and may also need information on social/political framework

18
Q

E-LCA and S-LCA -

Life Cycle Inventory

A

S-LCA has different data sources depending on the stakeholders

  • Mass balances are relevant for E LCA but not for S LCA
  • In S-LCA, qualitative data (and subjective information) are sometimes the most appropriate information to use.
19
Q

E-LCA and S-LCA

Life Cycle Impact Assessment

A

• E-LCA :

  • Inventory indicators are allocated into impact categories at midpoint or endpoint level
  • Areas of protection ( AoP )): human health, ecosystem quality and natural resources

• S-LCA:
- Inventory indicators are allocated to subcategories (= socially relevant issues) and later to impact categories or stakeholder groups → consistent characterization
models are missing!
- Area(s) of protection ( AoP): social or human well being or human dignity, sometimes
social justice and further

• The use of performance reference points is specific to S LCA, e.g. thresholds (targets)

20
Q

What should be defined in S-LCA?

A
  • Stakeholders
  • Impact categories
  • Subcategories
  • Inventory indicators for distinct impacts
21
Q

General approach and preparation for S-LCA

A
  • What are the relevant social issues?
  • What are the causes for social impacts?
  • How to classify the impacts?
  • What do we want to assess/measure?
22
Q

What are social impacts?

A

Positive and negative social consequences at the defined endpoint (e.g. human well being ) in relation to the stakeholder group.

23
Q

A
  • Workers:
    • Child labour
    • Fair salary

    • Local employement
  • Society
    • Prevention and mitigation of armed conflicts

24
Q

25
Q

Phases of S-LCA

A
  1. Goal and Scope
  2. Inventory Analysis: Phase where data are collected , the system boundaries are modeled and the LCI results are obtained
  3. Impact Assessment: Phase where data are related to the subcategories and impact categories
  4. Interpretation: Phase where results are critically reflected and optimization potentials are identified
26
Q

Functional unit

A

Definition and description of the utility thus the role that the product plays for consumers.

27
Q

What does the functional unit describe?

A
  • Functionality
  • Technical quality
  • Aesthetics
  • Costs related to purchase, use and disposal
  • Specific environmental and social properties of the product
28
Q

Reference flow

A

Measure of the required inputs and outputs of processes in a given product system to fulfill the function expressed by the functional unit

29
Q

Life Cycle Impact Assessment

A

Life Cycle Inventory Data –> Inventory Indicators –> Subcategories –> Impact categories
