EXIOBASE is an comprehensive collection of processes that detail the environmental impacts of generic commodities worldwide. Similarly to USEEIO, it is also an input-output database, which was developed by harmonizing and detailing supply-use tables for a large number of countries, estimating emissions and resource extractions by industry.
Key features
Commodities (products): 200 (across 163 industries)
Geographies: 44 countries + 5 Rest of World (RoW) regions
Available functional units: EUR2020, EUR2022, EUR (€)
Conversion rate from EUR2020 to EUR2022: 1.1120
Conversion rate from EUR2020 to EUR2025: 1.2262
Environmental extensions: 417 emissions categories, 662 material/resource categories
Exiobase in Earthster
Earthster currently provides Exiobase datasets in a system-process format. The full unit-process data available in the original Exiobase database is not yet supported due to its size and complexity, but we are actively working on implementing this functionality.
These system-process datasets can be used for calculations and give the same results as the unit-process data.
Currency scaling
Exiobase 3.9.6 is by default specified in EUR2020. We have also provided EUR (base year 2025) and EUR2022 scale units, and their conversion factors were calculated using Eurostat HICP inflation indices (Euro area - 20 countries). The conversion factor is calculated by comparing yearly averages between either year 2025 or 2022 with the base year of 2020, respectively, reflecting the latest official data available at the time of release.
Methodology and impact assessment
