" Figure 3: The most greenhouse gas (GHG) emitting industry in 2018 remained energy supply ","" "GHG emissions for the six most GHG intensive industries, UK (residency basis), 1990 to 2017 and provisional 2018","" "","" "Notes","1. Industry aggregations are based on the UK Standard Industrial Classification (SIC) 2007. Only those industries with the highest level of GHG emissions are shown. Names are shortened in this chart as follows: energy = electricity, gas, steam and air conditioning supply industry section; agriculture = agriculture, forestry and fishing section; water supply = water supply; sewerage, waste management and remediation activities industry section; transport = transport and storage industry section. 2. Environmental accounts estimates of total GHG emissions are produced on a residency basis in line with the United Nations System of Environmental-Economic Accounting and may differ from other estimates in the public domain. Differences are explained in the Air Emissions Quality and Methodology Information report.
