Adjusting emissions for external temperature does not change the long term trend 
 
Temperature adjusted emissions estimates remove the estimated effect of external temperatures Emissions are calculated for each quarter, with the preceding four quarters summed to create a rolling annual total The energy supply sector experienced the largest reduction in CO2 emissions from 2017-2018 
The reduction in power sector emissions has been driven by a shift away from using coal for electricity generation towards gas and renewables 
 
For the sectors not included here, provisional CO2 estimates for 2018 cannot be made as they cannot be derived from the energy statistics. Final 2018 estimates for all sectors will be published in February 2020, which will include total emissions by sector.
