Excel files: Idemat and Ecoinvent and ecocosts substances

There are two different datasets for students:

  • the Ecoinvent dataset with eco-costs (previously called Idemat)
  • the Idemat dataset, based on a set of carefully selected LCIs from peer reviewed literature and scientific databases of universities (previously called Idematapp)

Both datasets contain Simapro output on eco-costs, ReCiPe points, and CED. 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 types of electricity in different countries,
Idemat is stronger in the field of engineering:

  • 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)
  • a specific selection of LCIs for electricity and heat
  • 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.
