About this data
The Greenhouse Gas emissions Footprints Indicators are calculated by combining the OECD Inter-Country Input-Output (ICIO) Tables and other Greenhouse Gas Emissions databases, such as Air Emissions Accounts. Production-based emissions are estimated according to the residence principle. They refer to the GHG emitted from the resident economic activities and households of a country. Demand-based emissions encompass GHG emissions from the resident households of a country, as well as direct and indirect upstream emissions from its final expenditure of final goods and services. • Methodology: Measuring Greenhouse Gas Footprints in Global Production Networks • Note: Additional information on GHG FP indicators 2025 edition • Contact: icio-tiva.contact@oecd.org.
