I am very grateful to my hon. Friend for raising this very important issue. He has also reminded people that it was a Conservative Prime Minister who was one of the first world leaders to raise the issue of climate change and to put it on the international agenda. He asked about some of the changes that have taken place. Between 2010 and 2017, we reduced the UK’s domestic greenhouse gas emissions by 23%; in 2018, nearly 50% of UK electricity came from low-carbon sources; and UK CO2 emissions have fallen for six years in a row. That is just a few of our achievements. That is our record as a Government. But of course we continue to work internationally to help to deal with this issue, and that is why we believe it is so important to adhere to and remain part of the Paris climate change agreement.
