No major country is doing enough. That’s why the world is currently heading towards catastrophic warming of almost 3°C. Doing more than our neighbours isn’t the answer. We need to do enough based on what the science tells us.
But we are not ahead of similar countries on many metrics, and a growing number of countries are banning exploration for new fossil fuels (France, Spain, Denmark, Ireland) whilst the UK commits to maximise recovery of oil and gas from the North Sea.
We have cut our territorial emissions considerably since 1990, but much of that improvement was thanks to offshoring UK manufacturing. That isn’t cutting emissions – it’s moving them.
