It comes after various climate groups staged protests across Cornwall to lobby G7 leaders on environmental issues this weekend.
In their conclusions from this weekend’s summit, G7 leaders are expected to include a pledge to almost halve their emissions by 2030 relative to 2010.

This will also include promises to end almost all direct government support for fossil fuels and the phasing out of petrol and diesel cars.

Ahead of his address to world leaders, Sir David said: “The natural world today is greatly diminished. That is undeniable.
“Our climate is warming fast. That is beyond doubt. Our societies and nations are unequal and that is sadly is plain to see.

“But the question science forces us to address specifically in 2021 is whether as a result of these intertwined facts we are on the verge of destabilising the entire planet?
“If that is so, then the decisions we make this decade – in particular the decisions made by the most economically advanced nations – are the most important in human history.”
The G7 is also set to endorse an agreement on halting and reversing biodiversity loss by 2030, including a target to conserve or protect at least 30% of land and 30% of ocean globally by the end of the decade.
Meanwhile, Prime Minister Boris Johnson has used the summit to launch a £500m fund to support countries, including Ghana, Indonesia and Pacific island states, to tackle unsustainable fishing, protect and restore coastal ecosystems like mangroves and coral reefs, and reduce marine pollution.
“Protecting our planet is the most important thing we as leaders can do for our people,” he said.

“There is a direct relationship between reducing emissions, restoring nature, creating jobs and ensuring long-term economic growth.
“As democratic nations we have a responsibility to help developing countries reap the benefits of clean growth through a fair and transparent system.
“The G7 has an unprecedented opportunity to drive a global Green Industrial Revolution, with the potential to transform the way we live.”
For their final day of discussions on Sunday, G7 leaders will once again be joined by guest nations Australia, South Korea, South Africa and India.

What is the G7?
On Saturday night, the leaders enjoyed a beach BBQ in Carbis Bay and witnessed a flypast by the Red Arrows.
Critics questioned the display by nine aerobatic jet aircraft amid the summit’s focus on climate change.
Three British men are being held in Taliban custody in Afghanistan – including so-called “danger tourist” Miles Routledge who returned to the country after being evacuated by British armed forces less than two years ago.
The other two men are charity medic Kevin Cornwell and another unnamed UK national who manages a hotel in Kabul. They are believed to have been held by Taliban secret police since January.
A Foreign, Commonwealth and Development Office (FCDO) spokesperson said: “We are working hard to secure consular contact with British nationals detained in Afghanistan and we are supporting families.”
Mr Routledge, 23, has gained fame – and attracted controversy – by travelling to dangerous countries and posting about it online.
In August 2021 he was on a “holiday” in Afghanistan when he was caught up in the chaos in the capital as the Taliban took control of the country.
He chose the war-torn country having looked up a list of the most dangerous places to visit in the world, despite the Taliban taking control of more and more of the country at the time.
Mr Cornwell, 53, was arrested at his hotel by officers from the Taliban’s General Directorate of Intelligence (GDI) on 11 January.
He is accused of having an illegal firearm in the safe in his room, but his family say he had been granted a licence for the firearm.
The FCDO continues to advise UK citizens against all travel to Afghanistan based on the security risks involved, including the possibility of detention by the Taliban authorities.
Two women in Iran who went into a store while not fully covering their hair had yoghurt thrown over them by a man, in an incident captured on video.
CCTV footage showing the “yoghurt attack”, believed to have taken place in the city of Shandiz in northeast Iran, has been spreading on social media.
Iran’s President Ebrahim Raisi insisted that the hijab is the law in the country, in response to the widely shared clip.
It shows a man in a chequered shirt getting increasingly animated as he speaks to one of the women.
He is then seen grabbing a pot of what is believed to be yoghurt and throwing it over the pair before being confronted by another man and pushed out of the store.
Following the incident, the two women have been arrested for not covering their hair, according to judicial authorities.
The man has also been arrested for insulting the women, public disorder and “unconventional promotion of virtue”.
Authorities said the owner of the dairy shop, who confronted the attacker, had also been warned.

Reports on social media showed his shop had been shut, although he was quoted by a local news agency as saying he had been allowed to reopen and was due to “give explanations” to a court.
President Raisi said: “If some people say they don’t believe [in the hijab]… it’s good to use persuasion…
“But the important point is that there is a legal requirement… and the hijab is today a legal matter.”
Women in Iran had already been warned by the regime’s judiciary chief that they will be prosecuted “without mercy” if they are seen in public without a veil.
Following protests in recent months, Gholamhossein Mohseni Ejei said on Saturday: “Unveiling is tantamount to enmity with [our] values.
“Those who commit such anomalous acts will be punished and will be prosecuted without mercy.”
Iran has been rocked by huge waves of protests following the death of Mahsa Amini in September.
The 22-year-old Kurdish-Iranian woman died while in the custody of Iran’s morality police.
Women will be prosecuted “without mercy” if they are seen in public without a veil, Iran’s judiciary chief has warned.
Following protests in recent months, Gholamhossein Mohseni Ejei said on Saturday: “Unveiling is tantamount to enmity with [our] values.
“Those who commit such anomalous acts will be punished and will be prosecuted without mercy.”
He did not specify what the punishment would be, but violations of state laws on hijabs have seen people face arrest, fines, imprisonment and even the death sentence.
Women across the country have been refusing to wear their headscarves following the death of 22-year-old Mahsa Amini in September.
Ms Amini had been arrested for allegedly breaking the law on headscarves and died in police custody.

Nationwide street protests were met with a severe police crackdown.
Human Rights Activists, a group that has been tracking the crackdown from inside Iran, has reported more than 19,700 people being arrested during the demonstrations.
Another group, Iran Human Rights (IHR) estimates that 500 of them, including 70 minors, were killed by the regime.

Previously, Mr Ejei said that 22,000 people arrested during recent protests have now been pardoned.

Iranian women have now moved their fight online, with many posting videos of themselves with their hair and bodies exposed.
Under Iran’s Islamic Sharia law, women are obliged to cover their hair and wear long, loose-fitting clothes to disguise their figures.
Describing the veil as “one of the civilisational foundations of the Iranian nation” and “one of the practical principles of the Islamic Republic,” the interior ministry said in a statement on Thursday that there would be no “retreat or tolerance” on the issue.
The authorities are encouraging people to confront women who break hijab laws – something that has previously seen religious extremists physically attack them in public.
