Prince Charles will fly to Rome today, to warn leaders attending the G20 summit about the urgency of taking action on the climate crisis.
In recognition of his lifetime of environmental protection, he has been invited to speak at the international forum by the president of Italy.
And in a highly significant plea ahead of the Cop26 summit, the Daily Mail can reveal he will tell participants – including President Joe Biden of the US and, via video-link, president Vladimir Putin of Russia and president Xi Jinping of China – that while he feels ‘positive’ after devoting the last five decades of his life to the cause, immediate action is now crucial.

Prince Charles will fly to Rome today in order to warn leaders at G20 that it is too late to talk about the climate crisis. It is time to act now, not wait.

The invitation to address world leaders on such a prominent platform is unprecedented and is being considered a great honour.
Charles, 72, will say: ‘We must, now, translate fine words into still finer action.’
His words echo those of his mother who two weeks ago criticised world leaders’ inaction on addressing the climate change crisis at a reception following the opening of the Welsh parliament.
The Queen was overheard saying: ‘I’ve been hearing all about Cop… still don’t know who is coming. No idea. It’s really irritating when they talk but they don’t do.’
The Mail understands that both Charles and the Duke of Cambridge want to ‘do the Queen proud’ and ‘lead from the front’ in Glasgow next week.
The 95-year-old monarch’s ‘reluctant’ decision not to attend for health reasons has been a huge blow to the Royal Family, as well as the British Government.
Instead, she will be filming a video message at Windsor Castle this weekend that will be shown to delegates on Monday night.
She has also made clear that she wants the summit to be a success and see ‘meaningful action’ emerge as a result of it.
And the Royal Family will be rolling out the ‘big guns’ – with Prince Charles, the Duchess of Cornwall and the Duke and Duchess of Cambridge attending.
According to royal sources, the father and son are now closer than ever because of their common determination to tackle climate change.
‘Their passion for environmental issues [has] given them a new shared sense of purpose,’ a royal source revealed.
‘And they are determined to seize the unrivalled opportunities for consensus provided by Cop26 and make the Queen proud.’

Prince William, 39, hasn’t always had the easiest of relationships with his ‘workaholic’ father, spending much of his 20s and 30s at loggerheads with him.
But the pair have recently realised that they have more in common than they thought, especially after William’s first Earthshot Prize this month.
The awards help to solve the greatest environmental problems facing the world.
And one insider said: ‘The duke’s Earthshot awards, his growing admiration for his father’s clear-sighted thinking on this issue for more than half a century and the long run-up to Cop26 has been quite seismic for them.
‘The Prince of Wales is very proud of what his son has achieved and William, at long last, “gets” his father a lot better.’
On Monday, Charles and William, along with Kate, are due to co-host a joint reception for two of their personal environmental projects – the Earthshot Prize and the Sustainable Markets Initiative.

The second brings together business leaders to discover solutions that will aid the transition to a sustainable economy.
Along with Camilla, they will also attend an evening reception to mark the opening day of Cop26, at which the Queen’s recorded message will be played.
During the rest of the week, Charles and William will also be undertaking separate engagements in Glasgow.
The Prince of Wales will speak in Rome to G20 leaders before that. His role is being compared to King Edward VII’s, who was credited with pushing the Entente Cordiale agreement between Britain and France through the line in 1903.
In the same way, Prince Charles is being viewed as a unifying figure among disparate countries and interests on a topic with far reaching consequences for many others.
The future king will attend today’s reception and dinner hosted at The Quirinale Palace by president Sergio Mattarella, where he will also join other leaders for an official photo.
To deliver his key note speech, he will be attending the G20 Summit at La Nuvola conference center on Sunday.
The Prince intends to discuss his many years of often visionary – but sometimes ridiculed – work highlighting the environmental crisis. At the age of 19, he gave his first speech about the dangers of plastic.
Charles will also be discussing his shared ambitions regarding sustainability and advancements for the fashion industry.
