Emissions of CH4 - Total (Model Estimations, RIVM-MNP)

A global emissions source database called EDGAR has been developed jointly by TNO and RIVM to meet the urgent need of atmospheric chemistry and climate modellers and the need of policy-makers. The EDGAR database was to estimate the annual emissions of direct and indirect greenhouse gases (CO2, CH4, N2O; CO, NOx, non-methane VOC; SO2), including ozone-depleting compounds (halocarbons) for 1990 on a regional and grid basis. To meet the aim of establishing the global emissions from both anthropogenic and biogenic sources, a complete set of data would be required to estimate the total source strength of the various gases with a 1x1 degree resolution (altitude resolution of 1 km), as agreed upon in the Global Emissions Inventory Activity (GEIA) of the International Atmospheric Chemistry Programme (IGAC) Emissions of CH4 - Total (RIVM) include "Energy", "Agriculture", "Waste" and "Others" EDGAR subdivisions.

"Energy" comprises production, handling, transmission and combustion of fossil fuels and biofuels (IPCC category 1A and 1B); "Agriculture" comprises animals, animal waste, rice production, agricultural waste burning (non-energy, on-site) and savannah burning (IPCC category 4); "Waste" comprises landfills, wastewater treatment, human wastewater disposal and waste incineration (non-energy) (IPCC category 6); "Others" include industrial process emissions and tropical and temperate forest fires (IPCC categories 2 and 5).
