UK Greenhouse Gas Emissions by Sector
 
 
In the UK, GHG emissions arise from the following sectors:
 
Bullet Energy Industries
Bullet Industrial Processes
Bullet Solvents
Bullet Agriculture
Bullet Land-use, Land-use Change and Forestry (LULUCF)
Bullet Waste
 
Note: These broad source sectors comprise a series of sub-sectors as defined within the International Panel on Climate Change (IPCC) guidance on GHG inventories, which defines specific IPCC sector codes and provides the Common Reporting Format (CRF) used by all Kyoto parties in their reports to the United Nations Framework Convention on Climate Change (UNFCCC).
 
UK Direct GHG Emission Trends, 1990-2003
 
The largest contribution to greenhouse gas emissions arises from the energy sector. In 2003 this contributed 85% to the total emissions. Emissions of CO2, CH4 and N2O arise from this sector. Since 1990, emissions from the energy sector have declined by about 7%.
 
The second largest source of greenhouse gases in the UK is the agricultural sector. Emissions from this sector arise for both CH4 and N2O. Since 1990, emissions from this sector have declined by 14%, due to a decline in emissions from enteric fermentation and agricultural waste disposal (related to lower livestock numbers) and agricultural soils (due to changes in agricultural practices, including a decline in emissions from enteric fermentation, and a decline in the emissions from the use of synthetic fertiliser).
 
Industrial processes sector makes up the third largest source of greenhouse gases in the UK, contributing 4% to the national total in 2003. Emissions of all six direct greenhouse gases occur from this sector.
 
Land-use Change and Forestry contributes 2% to the national total in 2003. Emissions from this source occur for CO2, N2O and CH4. LUCF contains sinks as well as sources of CO2 emissions.
 
The remaining source that contributes to direct greenhouse gas totals is waste. In 2003 this contributed 1.7% to the national total. Emissions arise for CO2, CH4 and N2O, with emissions occurring from waste incineration, solid waste disposal on land and wastewater handling. Emissions from this sector have steadily declined, and in 2003 are estimated to have been 40% of those in 1990.
