Database Specific
Database Specific Abstract AbstractOECD Indicators on Carbon dioxide (CO2) emissions embodied in international trade (TeCO2) are derived by combining the 2021 editions of OECD Inter-Country Input-Output (ICIO) Database and of International Energy Agency (IEA) statistics on CO2 emissions from fuel combustion. In this release of TeCO2, emissions from fuels used for international aviation and maritime transport (i.e. aviation and marine bunkers) are also considered.
Production-based CO2 emissions of each country are estimated by allocating the CO2 emissions from fossil fuel combustion to the resident industries and households. The fuel combustion by resident industries and households includes the emissions from fuel consumption in both domestic and foreign territories.
Demand-based CO2 emissions of each country embody are the sum of the emissions of fuel combustion by resident households and the emissions from the final products producing industries and all the upper stage industries in the production chains.
Demand-based CO2 emissions are calculated by multiplying the intensities of the production-based emissions (c) with the global Leontief inverse (I-A)(-1) and global final demand matrix (Y) from OECD ICIO, taking the column sums of the resulting matrix and adding residential and private road emissions (FNLC), i.e. direct emissions from final demand: colsum [ diag(c) (I-A)(-1) Y ] + FNLC.
