IMPACT 2002+ is a methodology that was originally developed at the Swiss Federal Institute of Technology Lausanne (EPFL), Switzerland. Quantis made some updates to the original IMPACT 2002+ methodology version 2.1. These adapted versions are referred to as 'IMPACT 2002+ version Q2.21 (adapted by Quantis)' and 'IMPACT 2002+ version Q2.22 (adapted by Quantis)' (the later being a more updated version than the version Q2.21).
The life cycle impact assessment methodology IMPACT 2002+ proposes a feasible implementation of a combined midpoint/damage-oriented approach. The IMPACT 2002+ framework links all types of life cycle inventory results via several midpoint categories to four damage categories (human health, ecosystem quality, climate change and resources).
The main difference between IMPACT 2002+ v 2.1 (downloadable from http://www.impactmodeling.net) and IMPACT 2002+ vQ2.21 and vQ2.22 (adapted by Quantis and downloadable below) are
Overall scheme of the IMPACT 2002+ vQ2.21 and vQ2.22 (adapted by Quantis) framework, linking life cycle inventory results via the midpoint categories to damage categories, based on Jolliet et al. (2003a). Full arrows symbolize that a relevant impact pathway is known and quantitatively modeled. Dotted arrows represent impact pathways that are assumed to exist, but that are not modeled quantitatively due to missing knowledge, that are in development or that are double counted.
Detailed information on the construction of the methodology and the calculations behind are presented in the user guide. Here you can download the user guide and characterization factors for IMPACT 2002+ vQ2.21 and cQ2.22:
