Towards Uncertainty Management in LCA - Consensus Building and Practical Advice for Handling Uncertainty in LCA
1. Project title: Towards Uncertainty Management in LCA - Consensus Building and Practical Advice for Handling Uncertainty in LCA 2. Type of project: Group project 3. Number of participants: 10-15 4. Scope of the project: Global 5. Period: 4 years and started in 2008 6. Specific Goals: - Facilitate Management of uncertainty in all stages of an LCA study
- Establishment of recommended practice in uncertainty assessment and estimation within LCA
- Elaboration of Guidance for practitioners and developers on estimation, communication, interpretation and management of uncertainty
- Ensuring consistency and compatibility of approaches developed for inventory and/or impact assessment
- Development of a practical framework that describes how to get uncertainty estimates and how to model the uncertainty in LCA
- Provision of strategies for uncertainty reduction
- Improvement of communication and interpretation of uncertainty in LCA
- Provision of an information system on existing approaches with a distinction of LCI and LCIA for the level:
- input uncertainties
- uncertainty propagation,
- output uncertainties
- Provision of case studies on uncertainty management
- Recommend practice for method developers
- Minimize resources needed to perform uncertainty analysis in LCA
7. Activities: - Provision of existing approaches in a method library that will be accessible over the internet (wiki)
- Identification of suitable methods regarding input uncertainties
- Training courses for practitioners and stakeholders in uncertainty management
- Workshops/Conferences to provide discussion/exchange platforms for developers/experts
- Assess/estimate uncertainties within case studies
- Organize expert workshop or propose conference sessions aiming at an "expert consensus"
- Identification of suitable methods regarding input uncertainties, uncertainty propagation, and output uncertainties and derive specific advantages/disadvantages
- Dissemination of results developed
- Review by the TRC and the ILCB board
- Consultation of results with the Life Cycle Community
8. Output until now: - Guidance documents at an introductory level for practitioners
- Report including consensus on recommended practice for method developers
- Case studies with uncertainty management identified or carried out
- Wiki website available including existing/published approaches identified, suitable for LCA, including a discussion of advantages/disadvantages of each method in the context of LCA
- Project Group set up
- Proposal on various scenarios under discussion with the scientific community
9. Progress done so far: 10% 10. Leaders: Ralph Rosenbaum Technical University of Denmark
