Rishi Sunak has addressed world leaders at the COP27 climate change summit in the Egyptian resort of Sharm El-Sheikh.
The Prime Minister began his national statement by referring to the late Queen, as he said he believes the world can deliver on its climate promises.
He told the conference hall: “When Her late Majesty Queen Elizabeth II addressed COP27last year, she reflected how history has show that when nations come together in common cause, there is always room for hope.
“I believe we found room for hope in Glasgow.
“With one last chance to create a plan that would limit global temperature rises to 1.5 degrees, we made the promises to keep that goal within reach.
“And the question today is this: Can we summon the collective will to deliver them?
“I believe we can.”
The Prime Minister was attending the conference following what opponents called a “screeching U-turn”, having planned to stay home to work on domestic financial issues.
Mr Sunak’s attendance at the gathering in the Red Sea resort alongside leaders such as US President Joe Biden and French President Emmanuel Macron, marks his first outing on the international stage since becoming Prime Minister last month.
At the start of the conference, UN secretary-general Antonio Guterres warned world is “on the highway to climate hell with our foot still on the accelerator”.
