Thousands of protesters have come together to march for climate justice in Glasgow, the Scottish city playing host to COP26.
Organized by Fridays for Future — a movement made famous by teenage activist Greta Thunberg — the march is the biggest protest to take place outside the summit so far. Thunberg is expected to speak at the event later.
Some participants told the BBC on Friday that they were angry with world leaders for not taking enough action to limit global warming, with one saying: "We are choking."

5:03 a.m.: Biden ‘right to criticize’ China over absence from COP26, U.S. Energy Secretary says
U.S. Energy Secretary Jennifer Granholm has said President Joe Biden's criticism of China for failing to show up at COP26 is fair.
"Is it right to criticize? Yeah." she said in an interview with CNBC's Steve Sedgwick.
China and Russia, two of the world's biggest polluters, did not send delegations to the summit, but their leaders did send messages to delegates in writing and via video.
Granholm told CNBC: "We do believe that clean energy can be an area that all major countries agree upon. It is disappointing though that the biggest emitters are not committing to reduce their greenhouse gas pollution."

4:56 a.m.: Wealthiest 1% must reduce carbon footprints by 97% within a decade, Oxfam says
By 2030, the carbon footprints of the world's wealthiest 1% will be 30 times higher than what's needed to limit global warming to 1.5 degrees Celsius, a new study has claimed.
Published Friday, the Oxfam-commissioned study, carried out by the Institute for European Environmental Policy and the Stockholm Environment Institute, found that while the planet's wealthiest people are on track to increase their emissions, the poorest half of the global population will still emit far below the 1.5 degrees Celsius-aligned level in 2030.
According to the research, a person in the richest 1% would need to reduce their emissions by around 97% from today's levels in order to be aligned with the 1.5 degrees Celsius goal.

U.S. Energy Secretary Jennifer Granholm has told CNBC that U.S. President Biden is committed to the green energy transition despite not joining an international pledge to phase out coal.

She added that the administration believed "building out clean" was a critical component of what Biden was asking Congress to pass when it came to reducing emissions.
"That means deploy, deploy, deploy the technologies we already have while we're in this transition, and those technologies include decarbonization of fossil fuels."

3:04 a.m.: What happened at COP26 on Thursday?
Here's a summary of the biggest developments from the climate summit on Thursday:
U.K. lawmaker Alok Sharma, who is serving as COP President, told a press conference that around $18 billion had been pledged to assist with the transition from coal to clean energy. He claimed: "the end of coal is in sight."
Twenty-eight countries joined an international alliance dedicated to phasing out coal, but the world's biggest burners of the fossil fuel – China, the U.S. and India – were not among them.
Patricia Espinosa, the executive secretary of the United Nations Framework Convention on Climate Change, told CNBC there was reason to be "cautiously optimistic" about the commitments made so far at COP26.
The International Energy Agency said its models showed the world would be on a trajectory to limit global warming to 1.8 degrees Celsius if all the commitments made at COP26 were honored. Despite the IEA hailing its projection as "excellent," it would mean the Paris Agreement's key objective to keep temperature rises below 1.5 degrees Celsius was missed.
Indonesian lawmakers claimed an agreement they signed on deforestation did not include a pledge to end deforestation by 2030. In a statement on Facebook, Environment Minister Siti Nurbaya Bakar said "forcing Indonesia to zero deforestation in 2030 [is] obviously inappropriate and unfair."
