You have to admire her ability to talk so passionately about a subject she apparently knows nothing about.
The UK has one of the highest reduction in co2 emissions in the developed world and the current government has bought forward targets and introduced an unprecedented level of direct investment to make that continue.
In simple terms there are about 65 countries with a higher per capita co2 emissions than the UK. UK emissions have reduced by about 4% per year for several years running whereas countries like India and China are increasing in double digits.
UK should be applauded for doing more than it's fair share.
