Air Transport CO2 Emissions

This database includes annual information on CO₂ emissions related to commercial passenger and freight flights, on both a territory and a residence basis, for 186 countries. These CO₂ emissions are estimated by the OECD, based on a consistent methodology across countries.

Air emissions - Greenhouse gas emissions Inventories

This dataset on air and climate presents trends in man-made emissions of major greenhouse gases and total emissions by gas and by source. National Inventory Submissions 2017 to the United Nations Framework Convention on Climate Change (UNFCCC, CRF tables), and replies to the OECD State of the Environment Questionnaire.

Air emissions - Air pollutants Inventories

This dataset presents trends in man-made emissions of major air pollutants by sources.

Air and greenhouse gas emissions by industry

Air Emission Accounts are available for European countries and a few non-European countries.

The System of Environmental-Economic Accounting (SEEA) Central Framework is an accounting system developed around two objectives: "understanding the interactions between the economy and the environment" and describing "stocks and changes in stocks of environmental assets". The SEEA combines national accounts and environmental statistics in a statistical framework with consistent definitions, classifications and concepts allowing policy makers to evaluate environmental pressures from economic activities at macro- and meso-levels.

Data refer to total emissions of CO2 (CO2 emissions from energy use and industrial processes, e.g. cement production), CH4 (methane emissions from solid waste, livestock, mining of hard coal and lignite, rice paddies, agriculture and leaks from natural gas pipelines), N2O (nitrous oxide), HFCs (hydrofluorocarbons), PFCs (perfluorocarbons), (SF6 +NF3) (sulphur hexafluoride and nitrogen trifluoride), SOx (sulphur oxides, NOx (nitrogen oxides), CO (carbon monoxide), NMVOC (non-methane volatile organic compounds), PM2.5 (particulates less that 2.5 µm), PM10 (particulates less that 10 µm) and NH3 (ammonia).

The OECD Air Emission Accounts present data based on ISIC rev. 4.

Air and greenhouse gas emissions by industry - OECD Estimates

The OECD methodology takes the emission data from the national greenhouse gas inventories submitted under the United Nations Framework Convention on Climate Change (UNFCCC) as a starting point. The emission data in the inventories are allocated to ISIC rev. 4 industries and households using the correspondence table proposed by Eurostat.

Carbon Dioxide Emissions embodied in International Trade (Edition 2021)

Indicators in the OECD database on Carbon dioxide (CO2) emissions embodied in international trade are derived by combining the 2015 version of OECD's Inter-Country Input-Output (ICIO) Database with International Energy Agency (IEA) statistics on CO2 emissions from fuel combustion.

Production-based CO2 emissions are estimated by allocating the IEA CO2 emissions to the 34 target industries in OECD ICIO and, to final demand for fuels, by both residents and non-residents.

Consumption-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.

The ICIO system includes discrepancies in the trade data (referred to as DISC). Emissions allocated to DISC are made explicit (e.g. in indicator FD_CO2). This ensures that global CO2 production equals global CO2 consumption.
