UK CO2 emission cut by 38% Or only 10%

UK CO2 emissions cut by 38% since 1990  Carbon Brief has an in depth look.

Highlights

Domestic Cut in CO2 emissions of 38%,  ( called Territorial Emissions too) , or even as big 43% CO2e , if non-CO2 GHG are calculated [ banned CFCs & changes in CH4 NOx]

 Electricity Generation . The "Dash For Gas"  switch from Coal to Gas &  Renewable , biggest factor, But Bioenergy is 1/3 of "renewable"

Leaking natural gas  which is methane not counted, but believed to be falling, [ could fracking increase methane leaks?]

Average car MPG change from 33 mph in 1990 to 40 mpg in 2017 , which is actually terrible progress & that was driven by EU legislation.  A 1959 morris minor or a 1980s Skoda does 40 MPG, so real improvements in engine efficiency have been undermined by selling people bigger cars.

But Shifting Manufacturing over seas Increasing Imports is significant , China is still using coal electricity, so increasing imported stuff increase CO2, If this is factored in,  the cut in Consumption CO2 Emissions is only 10% .  Consumption Emissions, is defines as CO2 of UK emissions + CO2 footprint of imports - CO2 of exports. Perhaps this is a better measure, but does not incentivize decarbonizing  export manufacturing.
