Boris Johnson to attack ‘corrosive cynicism’ on net zero at Cop27

Ex-PM to contrast optimism at Cop26 last year with failures of governments - including UK - to follow through

Boris Johnson will attack the corrosive cynicism" on net zero that is hampering UK, and global, efforts to tackle the climate crisis, in a speech at the UN Cop27 climate summit on Monday.

In a swipe at members of his own Conservative party, the former UK prime minister will contrast the success and spirit of optimism at Cop26 in Glasgow last November with the failures of governments - including the UK - to follow through on promises since.
