One of the important sources of greenhouse gas (GHG) emissions in the world is agriculture. The energy and climate policy of the European Union focuses on reducing greenhouse gas emissions and combating climate change in the non-ETS sectors, including agriculture. In Poland, greenhouse gas emissions from agriculture were 7.7 % of total greenhouse gas (GHG) emissions in 2015. Agriculture represented 30 % of total CH4 emission and 78 % of total N2O emission. The implementation of effective activities to reduce GHG emissions from agriculture should be preceded by an analysis of this sector. The aim of the study was to analyse greenhouse gas emissions (CH4 and N2O) from agriculture in Poland and its regional diversification and to identify the main areas of activity in agriculture to reduce GHG emissions. In the years 2007−2016, CH4 and N2O emissions from agriculture in Poland were at a similar level with neither rise trends nor downward trends. The annual average CH4 emission was 554 ± 7 Gg, and for N2O it was 52 ± 1 Gg. The emission of GHG expressed in CO2 equivalent from animal production covered average 53 % of the total GHG emissions from agriculture, and from crop production it was average 47 %. Cattle production had the largest share in emissions from livestock production, and the fertilization from the crop production. The GHG emission from agriculture per square kilometre strongly depends on the region (coefficient of variation = 46.8 %) and its average value in years 2007−2016 was 73 Mg CO2 eq•kmE-2. The highest were in the Podlaskie Province (143 Mg CO2 eq•kmE-2) and Greater Poland (134 Mg CO2 eq•kmE-2), where is intensive animal production.
