Prince Charles has told climate activists such as Extinction Rebellion and Insulate Britain that their protests which include blocking roads “isn’t helpful”.

The Prince of Wales has said world leaders gathering at the Cop26 summit should take ambitious action on climate change rather than “just talk”, and take notice of how “despairing” many young people are about the issue.

The future king has suggested climate groups should reconsider their approach to tackling climate change.

“I totally understand the frustration,” he said in an interview with the BBC.

“But it isn’t helpful, I don’t think, to do it in a way that alienates people… The difficulty is, how do you direct that frustration in a way that is more constructive rather than destructive?”

He added: “The point is, people should really notice how despairing so many young are.”

Charles, a long-standing environmental campaigner, said it had taken “far too long” for the world to take the climate crisis seriously.

Prince Charles on government’s response to climate change

He is concerned that leaders gathering at the Glasgow climate change conference from October 31 to November 12 would “just talk”.

“The problem is to get action on the ground,” he said.

Charles is due to attend a series of events at Cop26, alongside the Queen, the Duchess of Cornwall, and the Duke and Duchess of Cambridge.

He warned of a disastrous outcome if negotiators fail to ratchet up efforts to combat climate change at the summit.

“The risks now are so great if you don’t make the right move,” Charles said.

“It’ll be catastrophic. It is already beginning to be catastrophic, because nothing in nature can survive the stress that is created by these extremes of weather.”

Asked if the UK Government, as the host of Cop26, was doing enough to fight climate change, Charles replied: “I couldn’t possibly comment.”

Prince Charles’ Aston Martin runs on wine and cheese

In the BBC interview, Charles discussed his own efforts to reduce his carbon footprint.

“I haven’t eaten meat and fish on two days a week and I don’t eat dairy products on one day a week,” he said. “If more did that, you would reduce a lot of the pressure.”

He said he had converted his car, an Aston Martin he has owned for five decades, to run on what he described as “surplus English white wine and whey from the cheese process”.

The vehicle now runs on a fuel blend made up of 85% bioethanol and 15% unleaded petrol.

Charles also said he has tried to heat the royal residences as sustainably as possible, using biomass boiler systems at Birkhall and installing solar panels at London’s Clarence House and on the farm buildings of Highgrove, his home in Gloucestershire.
