World leaders gathered in Glasgow, U.K., on Tuesday for the second day of the highly anticipated COP26 climate summit.
Delegates were asked to accelerate action on climate change and commit to more ambitious cuts in their countries' emissions, all in an effort to limit global temperature rises.
Here are some of the biggest developments Tuesday:
Henry Fernandez, chairman and CEO of MSCI and CNBC ESG Council member, told CNBC earlier on Tuesday that many publicly listed companies were still "not aligned to a 1.5 or a 2 degree world."
He said that MSCI had been tracking data from around 9,300 companies and found that in aggregate they were responsible for the emission of around 11 billion metric tons of carbon and that this was on track to rise to 17 billion metric tons.
"Currently a lot of these publicly traded companies are aligned on a path to a 3 degree world, not a 1.5 or a 2 degree world, " he said.

Costa Rica President Carlos Alvarado Quesada told CNBC earlier on Tuesday that the world was locked in a "false dilemma" on who should go first on delivering on climate targets, or wait for cooperation from other nations.
However, Quesada acknowledged that "the clock is ticking and we are all, all in danger" from the climate crisis.
He said that if countries pointed fingers on taking action on climate change, combating the crisis would become more of a "geopolitical game."
"It's a matter of life and death for your children and grandchildren, my children and future grandchildren, everybody's," he said.

UBS Chairman Axel Weber told CNBC earlier on Tuesday that developing a greener capital market was one area where Europe was ahead, "at least for now."
However, he added that there was a risk that Europe could build a capital market model that is not "exportable" and was too "inward looking" but was optimistic that this wouldn't be the case.

BlackRock CEO Larry Fink told CNBC's panel that the world needs to create new thought processes when it comes to the energy transition.
"We need to reimagine how we could rapidly deploy new capital into the greening of the world, but not the avoidance of hydracarbons in the short run or we're going to have $120, $140 oil, and that's not a fair or just transition," he said.

U.S. President Joe Biden has said one of the most important things the world can do is reduce methane emissions as quickly as possible.
"It's one of the most potent greenhouse gases there is," he told COP26 attendees at the launch of the Global Methane Pledge, a pact to cut methane emissions by 30% by the end of the decade. "It amounts to about half the warming we're experiencing today."
Biden said signatories to the pact "could probably go beyond" the pledge's 30% reduction target.
"Today [almost] 100 countries are signing on to the pledge, accounting for half of global methane emissions or 70% of global GDP," he said. "It's going to make a huge difference, not just when it comes to fighting climate change — it's going to improve health, improve food supply and boost economies."

Fink told CNBC's panel at COP26 that "we can't just ask public companies to move forward without the rest of society."
"It's going to create the biggest capital market arbitrage, and we're seeing that more hydrocarbons have been sold to private companies in the last two years than almost any time ever," he said. "That doesn't change the world at all, it actually makes the world even worse because it moves from public disclosed companies to opaque private enterprises. So, the mission is failing if that's all you're doing."
Fink added: "If we don't ask society to move forward, if we don't ask private companies to move forward alongside public companies, we're never going to get to a decarbonized world, we're fooling ourselves."

BlackRock CEO Larry Fink has said it's essential for the public and private sectors to come together in the fight against climate change.
The bank announced a partnership with the French and German governments today, which saw the company raise $670 million to invest in sustainability in the emerging world.
"If we're going to be serious about climate change in the emerging world, we're going to have to really focus on the reimagination of the World Bank and the IMF," Fink told a panel at COP26.
"They are the senior lender, and not enough private capital's coming into the emerging world today because of the risks associated with the political risk, investing in brownfield investments — if we are serious about elevating investment capital in the emerging world … I'm urging the owners of those institutions, the equity owners, to focus on how we reimagine these institutions and rethink their charter."

Addressing delegates at COP26, Japanese Prime Minister Fumio Kishida has said Japan "will be working in full force to take on climate change."
"To bring about a decarbonized society Japan will produce renewable energy as much as possible and lead the way in the clean energy transition with a focus on Asia," he said.
He announced that Japan would provide up to $10 billion in the coming five years to assist with decarbonization across Asia, and would double its funding to help other nations adapt to climate change to more than $14 billion.

Billionaire Amazon founder Jeff Bezos has pledged $2 billion in funding for restoring nature and transforming food systems.
The funding, which will come from the Bezos Earth Fund, is part of Bezos' commitment of $10 billion to be spent on fighting climate change this decade.
"Nature is beautiful but it is also fragile," Bezos told COP26 delegates. "I was reminded of this in July when I went into space with Blue Origin. I was told seeing the earth from space changes the lens through which you view the world, but I was not prepared for just how much that would be true."

Irish Taoiseach Micheal Martin is optimistic that climate discussions are going well at the COP26 summit.
"We're making progress and I think there's a real strong sense of momentum here in relation to the whole agenda around climate change," Martin told CNBC's Steve Sedgwick in Glasgow.
"With the major commitments made by individual countries but also collectively, the tone was very strong yesterday at the opening," he said. Nonetheless, Martin added that there needed to be more progress made in the arena of climate finance.
"[We need to see] concrete reality to the pledges around finance," he said.

Speaking to delegates in a recorded video message, Russia President Vladimir Putin said the conservation of forests was crucial to limit global warming.
On Monday, Russia pledged its support for a landmark deal between more than 100 countries to end deforestation by 2030.
In Russia's objective to be carbon neutral by no later than 2060, Putin said, the country was relying on its "unique resource of forest ecosystems."
"Russia supports the draft joint declaration on forests and land use," he told the climate summit on Tuesday. "We expect its implementation to facilitate closer partnerships between all the stakeholders."

President of Guyana Mohamed Irfaan Ali has said countries must provide $100 billion a year to fight climate change.
"Climate change affects us all, but its effects are most severe on the poorest and most vulnerable – especially small island developing states and low-lying coastal states," he said during an address to delegates. "For us, it's a question of survival."
Ali urged countries to honor the pledge made as part of the Paris Agreement to spend $100 billion per year on climate action.
"Dishonored pledges are a recipe for disaster," he said.

Chinese leader Xi Jinping had to deliver his message to COP26 in writing as he was not given the option to speak to the summit via video, Beijing has reportedly claimed.
Xi is not in Glasgow for the climate summit and sent a written message to world leaders participating in the talks on Monday.
"As I understand it, the conference organizers did not provide the video link method," Chinese foreign ministry spokesman Wang Wenbin said on Tuesday, according to Reuters.

Bank of America President Brian Moynihan has told COP26 that the bank is working toward net zero emissions by 2050.
"To get there, we will provide $150 billion in financing through 2030 over $1 trillion, to the effort," he told the climate conference.
Moynihan said he is also serving as co-chair of Prince Charles' Sustainable Markets Initiative – a private sector-led effort to accelerate the transition to a low carbon economy.

Hyginus 'Gene' Leon, president of the Caribbean Development Bank (CDB), has said that small island developing states are facing some of the worst impacts of climate change.
"For the past 40 years, islands have been battered by natural hazards, yet access to finance remains completely inadequate," he said at a COP26 plenary session on Tuesday. "To better finance our development needs, we need to address economic recovery, climate action and human welfare. Partnerships will be critical."
The CDB, along with the Inter-American Development Bank and the Green Climate Fund, is proposing the creation of a multi-donor financing facility to enable private and public investments into Caribbean states.
