Greenhouse Gases

Volume 456: debated on Friday 2 February 2007

To ask the Secretary of State for Environment, Food and Rural Affairs what proportion of the UK’s output of greenhouse gases is accounted for by farm animals. (110495)

Total direct greenhouse gas emissions arising from the UK livestock sector (sheep, pigs, bovines and poultry) were 4.5 per cent. of the UK total emissions or 8.07 million tonnes of carbon equivalent (MtCe) in 2005. This was made up of: 5.03 MtCe of methane (of which 86 per cent. was from enteric fermentation in the animals digestive systems and about 14 per cent. from manure management); 0.96 MtCe of nitrous oxide emission from manure management; and 2.08 MtCe of nitrous oxide emissions from grazing and crop production for livestock feed.
