The UK is to review its long-term target to cut climate emissions as part of global efforts to curb rising temperatures, the government has announced. The announcement by clean growth minister Claire Perry during the Commonwealth heads of government meeting (Chogm) raises the possibility the UK could implement a target to reduce emissions to “net zero” by 2050, tightening the existing goal to cut greenhouse gases by 80% by that date. After the report, she said: “We will be seeking the advice of the UK’s independent advisers, the Committee on Climate Change, on the implications of the Paris agreement for the UK’s long-term emissions reduction targets.” John Sauven, executive director of Greenpeace UK, said the review was extremely important and could provide a “valuable lead” for other countries.
