"Figure 2: Greenhouse gas emissions intensity for the five most intensive sectors, 1997 to 2016 and provisional 2017","" "UK residency basis","" "","" "Notes","1. Greenhouse gas emissions intensity is calculated by dividing the level of greenhouse gas emissions by Gross Value Added (GVA) in constant prices. This is the difference between output and intermediate consumption for any given industry/sector. This means the difference between the value of goods and services produced (output) and the cost of raw materials and other inputs which are used up in production (intermediate consumption). Data are in constant prices with 2016 defined as the base year. 2. Details on the nowcasting methodology used can be found in this article.  3. All figures are reported to two decimal places. 4. Total figures are based on raw data and therefore may not sum due to rounding. 5. All emissions intensity figures exclude consumer expenditure. 6. Estimates for 2017 are provisional. 7. Industry aggregations are based on the UK Standard Industrial Classification (SIC) 2007. Not all industries (SICs) have been included. Note: before 2017 data are provisional: All emissions intensity figures exclude consumer expenditure. Industry level greenhouse gas emissions intensity calculations cannot be summed to reach total greenhouse gas intensity because it is calculated as a ratio."
