Any pact agreed at Cop26 in Glasgow will “set the future for our children and grandchildren”, the conference’s president Alok Sharma has said.

He said: “I still have the intention for us to be able to close Cop26 at the end of Friday. Everyone must come armed with the currency of compromise.

“We all know what is at stake in these negotiations, and indeed the urgency of our task.

“In very human terms, what we agree in Glasgow will set the future for our children and grandchildren. And I know that no world leader or country will want to fail them.”

A top Cop26 figure has said the consensus among transport participants is “stronger than ever” on the pace of changes needed to hit the Paris goal of limiting warming to 1.5C.

Nigel Topping, the summit’s “high level champion”, told a news conference that “we often talk now about a systemic transformation” in sustainable transport.

He said: “We’ve got countries, cities, states, vehicle manufacturers, fleet owners and investors.”

Mr Topping later dodged a question from a Japanese reporter, however, who had asked why Nissan, Toyota and the Japanese government had not signed up, even though those two firms have factories in the UK. “You’d have to ask them,” he said.

The UK has once again ranked highly in the Climate Change Performance Index (CCPI), which rates the way each nation is tackling the climate crisis, writes Samuel Webb.

But does the nation deserve to be called a “leading country” by climate experts? Or does the ranking flatter the UK’s efforts?

One well-known politician has achieved success at Cop26, even as Boris Johnson struggles to get leaders to commit to improved climate targets.

Alexandria Ocasio-Cortez has completed her quest to obtain Irn-Bru.

The Democratic congresswoman has also said she wanted to “touch Harris tweed and see a castle” during her trip to Scotland, though said the intensity of work at the summit was high.

Boris Johnson’s aim on his latest trip to Glasgow is to persuade other world leaders to up their ambitions on climate, a minister has said.

Robert Courts, the minister for aviation and maritime, told BBC Radio 4’s World at One programme: “We’re entering that final hard-yard stage of the negotiation where everybody’s ambition comes to the fore and everybody urges each to do better.

“The one thing that you can really see when you’re here at Cop is the huge energy, the huge ambition that motivates every single person here from government, from NGOs, through to members of the public.

“We all know that this is the defining issue of our times, it’s the biggest challenge of our times, we’re determined to deliver and there’s all sorts of ways in which we already are.”

Brazil’s environment minister has demanded that richer countries provide the £74.1bn annual funding agreed upon to help developing countries switch to clean energy and handle the impact of climate change.

“The $100bn target has not been met,” Joaquim Leite said in a speech in Glasgow on Wednesday. “And this amount is no longer enough for the world to build a new green economy with a responsible transition.”

The minister added that “more ambitious volumes with easy access and agile execution are needed for inclusive transformation to take place in every territory around the world.”

The draft Cop26 pact published this morning does not do enough to help millions of people at risk from a warming climate, according to a leading charity.

Jonathan Farr, a senior policy analyst at WaterAid, said in a statement: “This draft agreement is not good enough. World leaders have just 72 hours to turn around the life chances of millions of men, women and children across the globe who are facing the deadly impacts of climate change.

“Poor communities are already picking up the tab for our collective failure to take action on climate change and they are paying that bill through increasing water scarcity. Young girls miss school to fetch water, days are lost to ill-health and lives are cut short because of impacts these communities have done the least to cause.

“They cannot wait while world leaders struggle to put their hands in their pockets to deliver on a decade old promise to provide funds to help poorer countries adapt.”

World leaders from 200 countries are in Glasgow for the Cop26 climate summit, along with 20,000 delegates and tens of thousands more protesters, campaigners and pressure groups all brought together in the latest international effort to thwart the worsening climate crisis, writes Harry Cockburn.

Boris Johnson has arrived in Glasgow by train for meetings at Cop26, a week after being criticised for flying home from the climate summit.

The PM arrived at Glasgow Central Station ahead of meetings at the climate summit.

Downing Street was previously forced to defend Mr Johnson’s decision to return from Cop26 by private charter jet after his first visit concluded last week.

His official spokesperson said it was important he was able to travel while facing “significant time constraints”.
