The UK has made considerable progress decarbonising its economy, with total GHG emissions in 2018 at 42% below 1990 levels. The bulk of these emissions reductions has come from the power (-62% since 1990) and industry sectors (-49%), whereas transport (-3%), agriculture (-16%), and buildings (-18%) have lagged behind.
The steep emissions reductions in the power sector have come primarily from a shift away from coal-fired power, which supplied just 2% of total generation in 2019. Between 2012 and 2019, coal generation fell by 95%. This has coincided with, and been enabled by, a steep increase in generation from renewable sources (+210%, 2012-2019).
Since 2016, transport emissions have constituted the largest share of the UK’s total GHG emissions (27.5% in 2018).
