First Stage AA

Chapter 1 – AA Framework • Two-Stage Process • Options • Appendix 1: Summary of Required Information for AA

Reports

Chapter 2 – Product Requirements and Alternatives

• Function, Performance, Legal • Identification of Alternatives

12

First Stage AA Chapter 3 – Relevant Factors

• Factors for comparison • A factor is relevant if:

– Factor makes material contribution to impacts – There is material difference in factor’s contribution

13

Factors to Consider for Relevance:

Adverse environmental impacts

Adverse public health impacts

Adverse waste and end-of-life effects

Materials and resource consumption impacts

Physical chemical hazards

Exposure pathways

Life cycle segments

…

14

Relevant factors are nested: Appendix 3-1

Exposure Assessment Considerations

Chemical quantity

Exposures to the hazardous chemical in the product

Household and workplace presence of the product

Exposures during the product’s life cycle

19

Methods for Potential Exposure Evaluation

Exposure Assessment Models Conceptual Model

• Graphical representation of exposure source and receptors • Identify exposure pathways

– Fate and transport – Exposure routes – Potential receptors

20

Conceptual Model – Exposure Pathways

Chapter 8 — Economic Impacts

Internal Costs External Costs

• public health and environmental costs • costs to governmental agencies and non-profit

organizations

Not about absolute value of costs

Approaches Presented – with Flexibility

26

Examples of Costs

Morbidity and mortality Costs

Cost of emissions

Ecosystem services
