34th LCA Discussion Forum

Life Cycle Assessment versus CO2 footprint? (in English)

Discussion forum on Life Cycle Assessment
13th March 2008 Lausanne, 9 h 00, Hôtel Alpha Palmier (in front of the railway station)

We are pleased to invite you to the 34th discussion forum on Life Cycle Assessment on March 13th 2008.

The forum will be followed by the 2nd International ecoinvent Meeting on Friday March 14th 2008 in Lausanne, at the Polydôme, EPFL.

Both events will be held in English.

The importance of the climate change issue has grown impressively these last months. Companies and authorities today deal with carbon footprint assessment, carbon labelling, carbon offsets and other instruments. Currently, there are two different approaches to assess the climate impact of processes and organisations: either with Life Cycle Assessment (LCA) methods, or based on the greenhouse gas protocol (www.ghgprotocol.org) and its 'partners' e.g. the GRI Global Reporting Initiative and the WBCSD World Business Council for Sustainable Development. The two approaches use different concepts and therefore may yield different GHG emission results. In addition, LCA is not limited to climate change but includes other impacts on the environment. Does the fact that climate change is the current prime subject allow or justify not to consider other impacts?

The DF 34 will discuss the following questions:

- Which are the relevant differences between the two approaches of LCA and GHG protocol concerning GHG accounting? Is GHG accounting an "LCA light"?
- In which cases is it useful to focus the environmental assessment on GHG emissions only?
- How should GHG emission certificates be considered in an LCA / Ecobalance?
- What are the implications of the GHG methodology development on the life cycle assessment methodology?

We hope that this forum will be of interest for you and we are looking forward to welcoming you in Lausanne.

Arthur Braunschweig, Sarra Harbi and Yves Loerincik
