Excel files: Idemat and Ecoinvent and ecocosts substances

There are four different datasets for students:

  • the Idemat dataset, based on a set of carefully selected LCIs from peer reviewed literature and scientific databases of universities, academic year 2021-2022: Idemat 2022RevA.xlsx
    (the versions Idemat 2022.xlsx and Idemat 2021RevA.xlsx of last academic year, are still available)
  • for electricity, a special beta dataset is available, see Idemat 2021 Global Electricity: it includes worldwide electricity data of  218 countries plus the  26 electricity regions in the US, 44 provinces in India, 13 provinces of Canada and 31 provinces in China
    Note 1: the emission data of the EU, USA, and Canada are more recent and accurate than the LCIs of Ecoinvent and Gabi, see for an explanation Electricity in LCA
    Note 2: the original calculation of the Idemat 2021 Global Electricity applies data from 12019. For 2020 and 2021 data were not stable because of covid-19. For 2022 data are not stable because of the war in the Ukraine. We will wait for 2023 data to make new calculations.
  • the Ecoinvent dataset with eco-costs (EI V3-7 with eco-costs.xlsx) behind password
  • the Eco-costs dataset for foreground (scope 1) calculations Ecocosts 2022 V1-1 midpoint tables.xlsx 

The Idemat 2022RevA dataset contain Simapro output on eco-costs, carbon footprint, ReCiPe points, CED and EF. Both datasets have more or less the same structure of LCI lines, so it is easy for students to check the differences. However, both datasets have differences in special areas:
Ecoinvent has more data on chemicals and chemical processes, Idemat is stronger in the field of product design and engineering. Both datasets are strong in types of electricity in different countries.
Specific features of Idemat are:

  • extra LCIs of alloys (frequently used by designers and engineers)
  • a correction of the “market mix” data of metals
  • extra LCIs of wood types (softwood types as well as hardwood types)
  • LCIs for electricity that are more up-to-date than other databases
  • newer data on sea and road transport
  • extra LCIs of End of Life (combustion, waste incineration, recycling)
  • the Agrifoodprint data on food
  • extra manufacturing processing data from CES Edupack

Simapro users can download an Import file of Idemat free of charge. Open LCA users pay a low fee for Idemat (but the software is free).
The Idemat excel file, with data on eco-costs as well as carbon footprint, CED and ReCiPe, is open access on this webpage. It is the basis for the Idemat App for Materials Selection on IOS and Android, as well as the IdematLightLCA App.

Note 1. the name changed from Idematapp to Idemat as of 2012
Note 2. older versions, back to 2007, are available on request (to check old graduation reports)

Previous versions of the Ecoinvent data set are:
Note. Because of license restrictions, the Ecoinvent data sets 2014, 2015, 2016, 2018 and 2020 (with Ecoinvent v3 data) are only available for students of the University with a net id, either via https://software.tudelft.nl/413/ , or click on the link below

The 2008 EI V2.0 file contains eco-costs 2007, Ecoindicator ’99, Ecological Scarcity 2006 and BEES 2008.

Calculations on “foreground processes”

For calculations on “foreground processes” the eco-costs 2022 V2.1 data on emissions (over 30.000 substances) and resource depletion can be found in the table below (open access at the internet).
