Cop26 ‘literally the last chance saloon’ to save planet – Prince Charles | Cop26

“And as the enormity of the climate challenge dominates peoples’ conversations, from news rooms to living rooms, and as the future of humanity and nature herself are at stake, it is surely time to set aside our differences and grasp this unique opportunity to launch a substantial green recovery by putting the global economy on a confident, sustainable trajectory and, thus, save our planet.

“And, from what they tell me, the private sector is already there, eager to work with you and ready to play a hugely significant and game-changing role. This is why I am so grateful to have this chance to talk to you here today, and to shine a light not just on how far we’ve come, but also on how far we still need to go.”

Charles’s intervention come as Johnson prepares to greet more than 120 world leaders at the start of the two-week Cop gathering on Monday, with the UK prime minister using much of his time at the G20 event to push home a similar message that concerted global action is required.

On his way to Rome on Friday, Johnson told reporters that the success of Cop remained in the balance, likening the world’s struggle against the climate emergency to a football team losing 5-1 at half-time.

In comments on Saturday, Johnson said a lack of progress in Glasgow could prompt “very difficult geopolitical events” including mass migration and global competition for food and water.

In his speech, Charles stressed what he called “our overwhelming responsibility to generations yet unborn”, arguing that he did now detect a change in attitudes and “the build-up of positive momentum”.

Stressing the need for the private sector to also tackle the issue, Charles said it would need trillions of dollars of investment every year to limit warming to the target maximum of 1.5C above pre-industrial levels.

“No government has those sorts of sums, which is why I have spent so much time over the past 19 months trying to form a global alliance amongst the private sector, as I have long believed it holds the ultimate key to the solutions we seek,” he said.

Governments in turn needed to provide long-term leadership on the issue, as well as regulatory and financial support, he added.
