Charles has for decades warned about the dangers of climate change and the need to protect the environment, often earning him ridicule. The future king said that early criticism “wasn’t much fun as you can imagine” and said he had always been motivated by a desire to leave a better planet for future generations.When BBC climate editor Justin Rowlatt singled out Australia as a country “reluctant” to combat climate change and asked Charles what he would say to the Morrison government, the prince replied: “Well you gently try to suggest there may be other ways of doing things. In my case, anyway, otherwise you lot accuse me of interfering, don’t you?”Many federal Liberal MPs believe Morrison will confirm his attendance at the G20 summit in Rome and the Glasgow climate summit once a net zero by 2050 deal has been struck inside the government over the coming days.COP26 president Alok Sharma, the British cabinet minister in charge of the Glasgow event, has challenged Australia to nearly double its 2030 emissions reduction target and urged Morrison to attend the talks in person.“You’re some of our closest mates in the world, and we need you by our side to demonstrate the unity of purpose that is going to be really essential at this summit,” Sharma told The Sydney Morning Herald and The Age last week.LoadingCharles also told the BBC he had great sympathy for Swedish climate activist Thunberg and other young activists staging protests ahead of COP26.“All these young feel nothing is ever happening, so of course they’re going to get frustrated,” he said. But he warned the tactics of the Extinction Rebellion movement were counter-productive. “It isn’t helpful, I don’t think, to do it in a way that alienates people. I totally understand the frustration, the difficulty is how do you direct that frustration in a way that is more constructive rather than destructive?”In a lighter moment, Charles revealed the Aston Martin he has owned for 51 years has been converted to run on surplus English white wine and whey from the cheese-making process.LoadingHe also said he doesn’t eat meat or fish for two days a week and doesn’t consume dairy products one day each week. “That’s one way to do it. If more people did that you would reduce a lot of the pressure on the environment.”He also said unlocking the vast amount of capital and investment needed to transition to cleaner energy was a key goal of Glasgow, echoing a 2019 speech to the World Economic Forum in Davos in which he argued market-based solutions and tax reform were the best options to halt the damaging impacts of climate change.Get a note direct from our foreign correspondents on what’s making headlines around the world.
