Last week, the Prince of Wales sent Mr Biden a letter to congratulate him for his inauguration and addressing the fight against climate change. The new US President re-joined the Paris Climate Agreement, the international treaty that aims to tackle environmental issues.
He did so within hours of his swearing in ceremony after former President Donald Trump withdrew from the accord claiming the agreement was not created to protect the environment but to “kill” the American economy.
A royal source told the Mirror Prince Charles was “encouraged” by Mr Biden’s decision to re-enter the agreement and is said to be “full of admiration” for the US President.
They said: “The Prince was hugely encouraged that one of the very first acts the new President undertook was to reinstate the United States to the Paris Climate Agreement.
“The two men share the same indisputable view, that the global climate crisis is the biggest threat to humankind and needs to be dealt with utter urgency.
“Together they would be a huge force for good, campaigning to governments and big business alike to join together to enter a more sustainable phase for the planet’s future and the future of generations after they have gone.”
Environmentalist Chris Packham told the news outlet the two men will be a “real force to be reckoned with on the global stage”, labelling them “unselfish” in their fight against climate change.
He said: “It’s very heartening that these two elder statesmen are showing a significant thirst for this issue.
“With the best will in the world it won’t be solved in their lifetime so this significant investment in other people, essentially trying to save the planet for their children and grandchildren, which is so wonderfully unselfish and we should all be very encouraged by their efforts.”
The Prince of Wales has long been an advocate for environmental causes and recently launched a new initiative to mark half a century of campaigning.
His recently launched Terra Carta project aims to persuade businesses to join a charter to help end climate change.
Last month, the Prince appeared virtually at the global One Planet Summit event hosted by French President Emmanuel Macron to introduce his latest campaign.
He told viewers: “Today, I am making an urgent appeal to leaders, from all sectors and from around the world, to join us in this endeavour, and to give their support to this ‘Terra Carta’ – to bring prosperity into harmony with nature, people, and planet over the coming decade.
“I can only encourage, in particular, those in industry and finance to provide practical leadership to this common project.”
The Terra Carta aims to raise £7 billion in green investment before 2022 through the Natural Capital Investment Alliance.
Royal commentators Omid Scobie and Maggie Rulli analysed how Charles’ new efforts might change the future.
Mr Scobie told listeners: “This is really a huge step for Charles, and what he considers to be really part of the final chapter of his legacy as an environmentalist.
“This journey began in the 70s and here we are in 2021, really starting out big.”
Ms Rulli pointed out Charles’ figurative comparison between the Magna Carta, which dates back to the 1215, and the Terra Carta.
She added: “What was really striking for me was the philosophical angle that he took.
“The Magna Carta was this historic document that’s come to symbolise human rights, and the rights that humans and democracy should have.”
