Abstract. The Emissions Database for Global Atmospheric Research (EDGAR) compiles anthropogenic emissions data for greenhouse gases (GHG) and for multiple air pollutants based on international statistics and emission factors. EDGAR data provides quantitative support for atmospheric modelling and for mitigation scenario and impact assessment analyses as well as for policy evaluation. The new version v4.3.2 of the EDGAR emission inventory provides global estimates, disaggregated to IPCC-relevant source-sector levels, from 1970 (the year of EU's first Air Quality Directive) to 2012 (the end year of the first commitment period of the Kyoto Protocol (KP)). Strengths of EDGAR v4.3.2 include global geo-coverage (226 countries), continuity in time, and comprehensiveness in activities. Emissions of multiple chemical compounds, GHG as well as air pollutants, from relevant sources (fossil fuel activities but also, for example fermentation processes in agricultural activities) are compiled following a bottom-up (BU), fully-traceable and IPCC-based methodology. This paper describes EDGARv4.3.2 developments with respect to three major GHG (CO2, CH4, and N2O) derived from a wide range of human activities apart from the land-use, land-use change and forestry (LULUCF) sector and apart from Savannah burning; a companion paper quantifies and discusses emissions of air pollutants. Detailed information is included for each of the IPCC-relevant source-sectors, leading to global totals for 2010 (in the middle of the first KP commitment period) (with 95 % confidence interval in parentheses): 33.6 (±5.9) Pg CO2/yr, 0.34 (±0.16) Pg CH4/yr, and 7.2 (±3.7) Tg N2O/yr. We provide uncertainty factors in emissions data for the different GHGs and for three different groups of countries: OECD countries of 1990, countries with economies in transition in 1990, and the remaining countries in development (the UNFCCC non-Annex I parties). We document trends for the major emitting countries together with the European Union in more detail, demonstrating that effects of fuel markets and financial stability have had greater impacts on GHG trends than effects of income or population. These data (DOI: https://doi.org/10.2904/JRC_DATASET_EDGAR) are visualised with annual and monthly global emissions grid-maps of 0.1° ×0.1° for each source-sector; these data can be freely accessed from the EDGAR website http://edgar.jrc.ec.europa.eu/overview.php?v=432&SECURE=123.

Short summary
In support of the Paris Agreement, EDGARv4.3.2 provides global annual estimates, disaggregated to IPCC-relevant source-sector levels, from 1970 to 2012. The anthropogenic CO2, CH4 and N2O emissions were calculated bottom-up with international statistics and emission factors for 226 countries and spatially distributed. EDGARv4.3.2 is input for the top down modelling of the Global Carbon Project and for EU policy-making, needing GHG emission estimates for each country at the climate negotiations.
