As my right hon. Friend the Environment Secretary said yesterday, there is clearly more that needs to be done. All of us who are of an age to be here would probably recognise that our generations have not done sufficient to meet this challenge, but I think the hon. Lady underestimates how much work has been done by the United Kingdom. Since 2010, we have reduced CO2 emissions faster than any other G20 nation. Between 2010 and 2018, we reduced greenhouse gas emissions by about a quarter overall. Our renewable energy capacity has quadrupled since 2010, and the proportion of our electricity coming from low-carbon resources has increased from 19% to more than half in 2018, a record year for renewables. There is a lot more to do, but I think that that is a good record on which to base that future action.
