"Figure 7: Carbon monoxide emissions intensity fell 84% between 1990 and 2018","" "Other pollutant emissions intensity, UK (residency basis), 1990 to 2017 and provisional 2018","" "","" "Notes","1. Other pollutants emissions intensity is calculated by dividing the level of emissions by gross value added (GVA). GVA data are chained volume measures, in constant prices, with 2016 as the base year. 2. Other pollutant emissions intensity is calculated excluding emissions from households (referred to as “consumer expenditure” emissions in the datasets accompanying this article)."
