New approach to an inventory of CH4 and N2O emissions from agriculture in Western Europe
Agriculture accounts for 42% and 52% of the total methane (CH4) and nitrous oxide (N2O) emissions of the European Union in 1995 (EEA 1999). Due to their biogenic origin, these emissions show a large spatial and temporal variability not yet been accounted for in national inventories. Therefore within this paper, the sources and sinks of CH4 and N2O in agricultural soils, animals and manure in Europe are calculated by a new approach. This approach is partly based on an extension and adaptation of the IPCC/OECD 1997 method to European conditions. In comparison to the latter methodologies, the presented approach includes sources and sinks in agriculture missing in IPCC/OECD 1997 and allows to consider environmental and management controls of emissions from agricultural mineral soils.
