Impact assessment / characterisation methodology in One Click LCA

CML methodology

For all the tools targeting for European markets, the impact assessment methodology is CML –IA 2012, which is the methodology required by the European EN 15978 and EN 15804 standards. CML methodology was created by the University of Leiden in the Netherlands in 2001. Read more here.

TRACI methodology

For North American markets we use TRACI, short for “Tool for the Reduction and Assessment of Chemical and Other Environmental Impacts”, which was developed by the U.S. Environmental Protection Agency.

The TRACI impact categories of:
  • Ozone depletion
  • Global warming
  • Acidification
  • Smog formation
  • Eutrophication
Human health cancer, human health noncancer, human health criteria pollutants, and ecotoxicity were developed specifically for US conditions by using input data consistent with US locations. Read more here.
