The largest sources of anthropogenic CH4 emissions are agricultural activities, managed waste disposal on land, public power and district heating plants (Figure 2.4). The emission from agriculture derives from enteric fermentation and management of animal manure. The increasing CH4 emissions from public power and district heating plants are due to the increasing use of gas engines in the decentral-ised cogeneration plant sector. Approximately 3% of the natural gas in the gas engines is not combusted. From 1990, the emission of CH4 from enteric fermentation has decreased due to the decrease in the number of cattle. However, the emission from manure management has increased due to a change in traditional stable systems towards an increase in slurry-based stable systems. Altogether, the emission of CH4 for the agriculture sector has decreased by approximately 7 % from 1990 to 2004. The emission of CH4 from waste disposal has de-creased slightly due to increases in the incineration of waste.
