The largest sources of anthropogenic CH4 emissions are agricultural activities contributing with 79.8 % in 2016, waste (14.8 %) and the remaining emission sources covers 5.3 %, see the figures below. The emission from agriculture derives from enteric fermentation and management of animal manure contributing with 53.5 % and 27.1 % of the national CH4 emission excl. LULUCF in 2015. The CH4 emission from public power and district heating plants increased in the nineties, mainly 1992-1996, due to the increasing use of gas engines in the decentralised cogeneration plant sector. Up to 3 % of the natural gas in the gas engines is not combusted. The deregulation of the electricity market has made production of electricity in gas engines less favourable, therefore the fuel consumption has decreased and hence the CH4 emission has decreased.

Over the time series from 1990 to 2016, the emission of CH4 from enteric fermentation has decreased 8.1 % due to the decrease in the number of cattle. However, the emission from manure management has in the same period increased 19.6 % due to a change from traditional animal housing systems (using solid manure management) towards an increase in slurry-based animal housing systems. Altogether, the emission of CH4 from the agriculture sector has decreased by 0.4 % from 1990 to 2016. The emission of CH4 from solid waste disposal has decreased 59.7 % since 1990 due to an increase in the incineration of waste and hence a decrease in the waste being deposited at landfills and a ban on depositing waste fit for incineration.
