Lesson 8: Impact assessment methods
Explore the commonly used methods for assessing environmental impacts in Life Cycle Assessments.
- LCA results depend on goals, scope, and chosen impact assessment methods.
- Popular methods may vary by region, industry, and study requirements.
COMMON IMPACT ASSESSMENT METHODS
- Eco-indicator 99:
- Covers various impact categories, including climate change, ozone depletion, and human toxicity.
- Suitable for assessing sustainability in diverse industries.
- Provides comprehensive insight into environmental stressors.
- ReCiPe (Relevance Calculation and Impact assessment of environmental indicators):
- Wide range of impact categories, from global warming to freshwater ecotoxicity.
- Preferred for overall environmental performance assessment, policy-making, and sustainability reporting.
- CML 2002 (Centre for Environmental Science):
- Assesses environmental performance in manufacturing and energy industries.
- Evaluates impacts related to climate change, resource depletion, and more.
- Comprehensive assessment of potential environmental burdens.
- TRACI (Tool for the Reduction and Assessment of Chemical and other environmental Impacts):
- Developed by the US EPA, focuses on human health and ecological risks.
- Addresses 10 impact categories, including global warming and ecotoxicity.
- Useful for assessing chemicals and industrial processes.
- IMPACT 2002+:
- Widely used in Europe, covering major environmental impact categories.
- Suitable for evaluating products, technologies, and policies.
- Provides insight into human health, ecosystem quality, and climate change.
- Impact assessment methods are essential for evaluating LCA results.
- Different methods address a wide range of impact categories.
- Selection depends on the study’s goals and the specific requirements of the assessment.
