Excel files: Idemat and Ecoinvent, and eco-costs midpoint tables

There are four different ‘background’ datasets (‘scope 2 and 3’):

  • The scope 3 Idemat dataset, with some scope 2 data for heat and electricity, is based on a set of carefully selected LCIs from peer reviewed literature and scientific databases of universities. The most recent version is
    Idemat 2024-V2-1.xlsx
    This dataset is designed for innovation in the technosphere.
    The Idemat datasets contain Simapro output on eco-costs, carbon footprint, ReCiPe points, CED and EF.
    A proxi LCI table, based on the ClassyFire system (subclasses)  has been added to cope with chemical substances that have no specific LCI data in literature.
  • The Scope 2 and 3 Ecoinvent dataset with eco-costs (EI V3-8 with eco-costs.xlsx) which is available behind password
    Note. Because of license restrictions, the Ecoinvent data sets are only available for students of the Delft University of Technology, with a net id, https://software.tudelft.nl/413/
  • The ‘embedded electricity‘ dataset of Idemat scope 3 data Idemat embedded Electricity excel, to correct Idemat data for regional electricity and renewable electricity. See for explanation on how to use these data Faq 2.17.
  • For the Dutch industry: eco-costs and carbon footprint estimates per kWh of the Dutch electricity providers.
    See Dutch electricity data 2021.
    This dataset is based on the actual purchases of electricity, rather than the GO’s
    (GOs are not suitable for LCA, as they are used for greenwashing, see this explanation).
    Note. please contact us in case you think that your company scores better at the moment.

the Idemat excel and Ecoinvent excel 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 a bit more data on chemicals and chemical processes, Idemat is stronger in the field of product design and engineering (e.g. plastics, textiles, alloys, and wood species). 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 Ecoinvent
  • newer data on sea and road transport
  • extra LCIs of End of Life (combustion, waste incineration, recycling)

Simapro users can download an Import file of Idemat free of charge.
Open LCA commercial users pay a low fee for Idemat (but the software is free). For Academic users, Idemat in Open LCA is free.
The Idemat excel file is CCBY NC open access . It is the basis for the Idemat App for Materials Selection on IOS and Android, as well as the IdematLightLCA App.

Previous versions (to check old reports, theses, and papers) are available on request.


Eco-costs midpoint tables on ‘foreground’ processes (‘scope 1’)

For calculations on “foreground processes” the eco-costs 2023 V1.0 data on emissions (more than 120.000 data lines) and resource depletion can be found in the table below (open access at the internet).

Social eco-costs

For calculations on social-eco-costs the eco-costs 2012 V3.3 data (which are applied in Simapro) can be found in:

s-eco-costs 2012 V3.3 data in Simapro.xlsx excel file (0,8 MB) (for s-eco-costs of other countries see OSH data)

Another dataset can be found in the S-LCA tool
