Eora66 MRIO factor set

With coverage dating back to 1990, EORA MRIO (Multi-region input-output) is a globally recognized spend-based emission factor set.

IBM has modified EORA concordance tables to align with Summary categories provided by the US EPA. This alignment provides a breakdown of 66 industries and commodities.

This factor set will be updated annually, usually in July or August, depending on data availability.

Summary

The Eora global supply chain database consists of a multi-region input-output table (MRIO) model that provides a time series of high-resolution input-output tables with matching environmental and social satellite accounts for 188 countries.

The IBM IBM® ESG Suite implementation of the factor set has taken the full Eora dataset and mapped national classification systems to a harmonized classification used by the US EPA across 66 categories. For the full list of national classifications before harmonization, see here.

The categorization of the 66 spend data types originates from the US Department of Commerce - Bureau of Economic Analysis. For more information see the BEA categorization, and review the Supply and Use tables provided on the BEA website here.

Currency options

All emission factors are stored in USD, therefore all spend data must also be stored in USD for the emissions calculation to work. To accomplish this we provide three options for capturing spend data.

Account styles can be configured to capture spend data in:

  • USD
  • The local currency of the location
  • A currency of the user's choice that is accessible by a list containing currency codes within the account style. A limited subset of currency codes can be selected when configuring account styles.
Geographical coverage 188 countries.

Effective and published dates

Country-level emissions data, input-output tables and country-level GDP take some time to tabulate. Therefore published dates are going to be set in 18-months after the effective period.

For example, in July 2023, emission factors were loaded for the calendar year 2022, and in July 2024, factors will be calculated and loaded for Jan - Dec 2023.

For more information on effective and published dates see this article.
