Methods update SimaPro 7.3.3
We release this extra methods update to give our SimaPro users early access the ILCD recommended LCIA midpoint methods and important updates to the ReCiPe and TRACI methods
In this update known errors in the ILCD method are corrected.
This update contains:
- updated ILCD 2011 recommended LCIA midpoint method (v1.01)
- updated ReCiPe methods (v1.07)
- updated TRACI 2.1 (v1.00) method including normalization
- methods manuals
Download and run the MethodsUpdateDatabase733.exe file, a pdf file with update instructions will open. Please read and follow the instructions carefully. Make sure you remember where you installed the update database.
Make sure you use the "AppendSubstancesMethodsUpdate733.xls" file to append your subsance list. This file is installed in the same location where your update database is installed.
ILCD Method (v1.01)
The ILCD Recommended method is a result of a project for the European Commission that analyzed several life cycle impact assessment (LCIA) methodologies to reach consensus on the recommended method for each environmental theme, at both midpoint and endpoint. The endpoint methods, however, are not included in SimaPro because the list is far from complete. No method development took place in the development of the ILCD recommendations. The intention was to identify and promote current best practice. These recommendations do not include weighting across impact categories, nor normalization relative to a reference, e.g. impacts in a given region.
Since the first release of the method, a number of serious problems have been identified. These are corrected in version 1.01 (see the method comments for details). JRC will soon post an updated list of characterisation factors on http://lct.jrc.ec.europa.eu.
In the ReCiPe methods two errors were corrected, which will affect the results of your calculations. In the Fossil depletion impact category of the ReCiPe endpoint methods (I, H, and E), a conversion error was found, which leads to an overestimation of 10-30 percent of the impact for single score results. With the correction of this error, the endpoint characterisation factors for fossil fuel depletion ($/kg) are a factor 135 lower. The factors for mineral depletion ($/kg) remain the same; so they become relatively more important after normalisation and weighting. As the normalisation factors are recalculated as well, the single score values will change a lot less, except for precious metals; there the change can be significant. We recommend to recalculate critical results that were calculated using the ReCiPe endpoint methods.
Also errors in the Terrestrial, Freshwater and Marine ecotoxicity impact categories were corrected, which result in higher characterization factors in these categories (a factor 1.1, 3.3 and 220, respectively).
You can find more information about the ReCiPe method, the updated report and the Excel file with the factors on www.lcia-recipe.net.
The TRACI 2.0 method was updated to TRACI 2.1. In TRACI 2.1, Global warming was updated to match IPCC2007, toxicity impact categories were converted to the USEtox model and fossil depletion was added following Eco-indicator 99. This method now also contains normalisation factors for the US and US-Canada. For the US, the reference year for the inventory data collected is 2008, whereas for the US-Canada, Canadian data from Lautier et al. (2010) for 2005 was used and updated for relevant substances with data from 2008.
You can find more information about TRACI 2.1 in the user manual.
More information about the changes can be found in the comment field of each method, and in the methods manuals.
