WifOR’s GHG Emission Factors enable companies to assess their Scope 3 emissions along the supply chain, applying the spend-based method recommended by the GHG Protocol. Emission factors for greenhouse gases are calculated using WifOR’s own input-output table. These are based on the European Commission’s Emissions Database for Global Atmospheric Research (EDGAR) and supplemented by metrics from Eurostat and the OECD.
WifOR’s GHG Emission Factors support companies in understanding and communicating their upstream Scope 3 emissions transparently, while enabling the development of targeted measures to enhance environmental performance.
- The data package provides spend-based emission factors for 10,528 data points across 188 countries and 56 sectors. The offered indicators, countries, and sectors are listed here.
