The largest sources of anthropogenic CH4 emissions are agricultural activi-ties contributing in 2015 with 80.6 %, waste (14.0 %), public power and ener-gy industries (1.2 %), see Figure 2.4. 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 de-creased. Over the time series from 1990 to 2015, the emission of CH4 from enteric fermentation has decreased 9.2 % due to the decrease in the number of cattle. However, the emission from manure management has in the same period increased 20.1 % 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 ag-riculture sector has increased by 1.1 % from 1990 to 2015. The emission of CH4 from solid waste disposal has decreased 57.3 % since 1990 due to an in-crease 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.
