Estimates of greenhouse gas (GHG) emissions by industry, based primarily on Air Emissions Accounts (AEA) and drawing on other sources of GHG emissions statistics, can be combined with OECD’s Inter-Country Input-Output (ICIO) tables to produce estimates of emissions from consumption (or demand) perspectives. This allows indicators of GHG footprints to be developed, revealing the emissions associated with intermediate consumption, final consumption and capital formation expenditures along global production chains. The use of emissions statistics compiled under the System of Environmental Economic Accounting (SEEA) framework, which is based on the resident principle, allows calculation of production-based emissions by industry that cover not only CO2 emissions from fuel combustion, but also non-fuel combustion emissions.
Building on earlier production‑based and demand‑based measures that focused solely on CO₂ emissions, the GHG footprint indicators capture emissions embodied along domestic and international production networks, and those associated with final demand at purchasers’ prices.
In line with the latest OECD ICIO tables, this edition introduces finer sectoral detail in agriculture, mining and quarrying, basic metal and other transport equipment manufacturing, enabling more detailed analysis of activities such as crop and animal production, coal and crude petroleum extraction, iron and steel production, and shipbuilding.
The database comprises five dataflows covering:
- production-based GHG emissions
- GHG emissions embodied in domestic final demand (at basic and purchasers’ prices)
- GHG emissions embodied in trade (including net exports, net imports and domestic emissions in exports)
- the split between domestic and foreign GHG emissions in final demand
- production-based and demand-based indicators expressed per capita and per US dollar of GDP.
