Discussion Forum on Life Cycle Assessment

Mission and Organisation 

LCA practitioners working in industry, consulting companies and administration and LCA scientists. Each LCA forum is dedicated to a specific topic of immediate interest related to

  • experiences and challenges with LCA application in industry and administration
  • scientific questions in life cycle inventory and life cycle impact assessment metholodogy development
  • dissemination of new scientific findings and results of relevant LCA studies

The LCA Discussion Forum is a platform for the exchange between Internationally reknown speakers are invited according to the topic to present their work. Each forum offers an "open floor" session for short presentations. The LCA forum is dedicated to people interested in the field of LCA, working in Switzerland and abroad. Its content is defined by an advisory board.

Upcoming Meeting

DF 76 — The use of LCA as a development tool for emerging technologies / How to deal with forecasts in LCA? 

Thursday, 19 November 2020 – Online conference – Detailed access information will we communicated to all participants

(Change of location due to the Covid-19 pandemic.)

We cordially invite you to the 76th Discussion Forum on Life Cycle Assessment.
The official language of this event is English. 

In light of developing innovative technologies with better environmental considerations, LCA comes as one of the tools to steer and guide designs at its early phases. Introducing LCA and its implementation at this stage, however, is not a straightforward task as there are underlying challenges to be resolved. A valid assessment should take into account technology developments on maturity, upscaling and industrial learning, inventory data gaps and system changes for different sight years, e.g. energy transition, circular economy and emission regulation developments, which are involving changes in foreground as well as background life cycle inventory. We have seen many developments in the past few years on this topic and this DF will be the perfect platform where everyone shares insights, which might lead to future collaboration.

This DF will show state-of-the-art approaches that aim to perform prospective LCA for new and innovative technologies and how to communicate the results. Furthermore, some tools and frameworks that might support the modelling of future technologies and interpretation from various aspects will also be highlighted (e.g. scenario analysis and incorporation, open-source software, uncertainties handling, etc.). 

To summarize, this DF will culminate with discussion about applying prospective LCA methods and recommendations for improvements for accelerating prospective LCA joint practices on emerging technologies’ developments.

Future Meetings

Call for short presentations:

You work on a topic relevant to one of the announced Discussion Fora and wish to present your findings?

"Open floor" sessions for short presentations will be available in each forum. Please contact the LCA Discussion Forum secretariat – the sooner the better.

DF 75 (Jubilee DF) — Life Cycle Thinking = Lower Footprint? – Or: Is LCA relevant?

Due to the Covid-19 pandemic, the jubilee forum is moved to 2021.
It shall take place as a physical meeting at a later date. It will be assigned a new DF number. 

Cancelled date: Monday & Tuesday, September 14 & 15, 2020 (2 day jubilee forum), Zürich

If we compare the necessary large transformations (e.g. in GHG reductions, or land use patterns) with common LCAs, the question arises: Did LCA hitherto support big decisions and changes? Or are we using LCA mostly for minuscule optimizations? We're eagerly awaiting your abstracts for presentations and posters which answer one (or many) of these questions: 
   • How much does (did) LCA really help in reducing pressure on the environment? 
   • Which important decisions were based on LC thinking and analysis?
   • How can LCA become more effective for big issues?

Call for Abstract closed.
