Promoting global consensus on Life Cycle Impact Assessment Indicators

The Life Cycle Initiative’s flagship publication “Global Guidance for Life Cycle Impact Assessment Indicators Volume 1”  goes a long way in identifying the “current best practice”, and recommended characterization factors in a variety of impact areas:

  • climate change;
  • health impacts of fine particulate matter;
  • water use impacts; and
  • land use impacts on biodiversity.

What makes this guidance so unique is the global consensus-building process, and its endorsement by an international partnership. Such robust and international backing should make these indicators especially attractive to be used in policy and reporting frameworks requiring recognition and stability.

Global Guidance on Life Cycle Impact Assessment Indicators: Volume 2

The Global Guidance for Life Cycle Impact Assessment Indicators 2 is continuation of a series of reports addressing these issues. Aimed at life cycle assessment practitioners and method developers, it identifies the “current best available practice” in a variety of areas. This 2nd Volume focuses on Acidification & Eutrophication, Human Toxicity and Ecotoxicity, Mineral Resources, and Soil Quality. The global importance of these impact areas is also recognized in specific Sustainable Development Goals (SDGs), as well as in several resolutions of UNEA4.

The guidance also strengthens the position of the Life Cycle Initiative as a global body for the stewardship of impact assessment methods, delivering much-needed consensus-building among method developers and users at the interface between science and decision- and policy-making. It has been built with significant in-kind contribution of hundreds of experts in the last few years. More practically, it provides the necessary access to internationally endorsed, scientifically robust, and stable indicators so that life cycle assessment users can incorporate them in their studies.


Please note: we have not yet finalised with the curating of the Characterization Factors file for the Volume 2. We do not at the moment have an estimate of when the file will be uploaded, but certainly by the end of 2020.
