(CNN) - The mood in Glasgow was optimistic this Tuesday when world leaders concluded their high -level summit at the COP26 climate conference.Several important ads illuminated the perspective on whether the meeting can achieve significant results.

This is what happened on the second day.

The great promise on methane in Cop26

Around 100 nations and parties have signed a global commitment to reduce methane emissions by 30% of 2020 levels by 2030, the president of the European Commission, Ursula von der Leyen announced Tuesday in Glasgow.

Methane, which is the main component of natural gas, is an extremely powerful greenhouse gas.Invisible and toilet, it has 80 times more short -term heating power than carbon dioxide.

Von der Leyen said that reducing methane emissions "will immediately slow down climate change.".

Helen Mountford, vice president of Climate and Economics of the World Resources Institute, an environmental research organization, said that reducing methane emissions was essential to prevent the planet from heating beyond 1.5 degrees Celsius, a key threshold identified by the scientists.

"This promise...It establishes a solid floor in terms of the ambition we need worldwide, "Mountford said in a statement."The energetic and rapid action to reduce methane emissions offers a variety of benefits, from limiting short -term heating and curbing air pollution to improving food safety and public health".

The president of the United States, Joe Biden, said that the impulse to reduce methane emissions is both an economic and environmental opportunity.

"This is not just something we have to do to protect the environment, our future," Biden said Tuesday."It is a huge opportunity, a huge opportunity for all of us, all our nations, to create jobs and make significant climatic objectives a fundamental part of our world economic recovery".

China would sign up for '1.5 degrees'

China's special envoy for climate change, Xie Zhenhua, said Tuesday that his country "did not resist" the objective of limiting global warming to 1.5 degrees Celsius above pre -industrial levels.

China has been reluctant to strictly commit to the 1.5 degree figure and has preferred to say that they will commit to maintaining the heating "below 2 degrees and as close as possible of 1.5 degrees".

But Xie seemed to be preparing for the goal this Tuesday.

"I don't resist the 1.5 degree target.That is part of the objectives of the Paris agreement, in reality.Talk about global climatic objectives should be based on rules.Since 1.5 degrees Celsius is part of Paris's objectives, we are certainly not against this goal, "he said.

China is the largest pollutant in the world, so its support for the objective is vital.Xie is China's main climate negotiator and, as such, it could be said that she is one of the most powerful people attending the Cop26 Summit in Glasgow.Earlier this Tuesday, he criticized the West for "not fulfilling" his commitment to provide annual climate financing of US $ 100.000 million for developing countries.

"Recientemente hablé con el máximo presidente de la COP26, Alok Sharma, y ​​con (el enviado de Estados Unidos para el clima) John Kerry y ministros de muchos otros países.And they told me that we have to wait until 2022 or even 2023 to achieve the objective of US $ 100.000 million, the objective set by 2020, "he told reporters.

Meanwhile, speaking with Christiane Amanpour of CNN this Tuesday, Kerry said that the United States was working with China "without challenging them in any personal way".

"China has said 'let's strictly limit coal," Kerry said."What we are trying to do is work with China in a cooperative way to show how they could accelerate the transition".

Helping South Africa in the transition of coal

The United States, the United Kingdom, France, Germany and the European Union have announced that they will help finance the transition from South Africa to the use of coal.

The United Kingdom Prime Minister Boris Johnson said the initial association of US $ 8.500 million would help South Africa decarbonize its carbon intensive energy system.The details of the financing have not yet been announced, and the diplomats hope that the small print will be resolved in the coming months.

Climate scientists and some diplomats say that the South Africa Agreement could pave the way for similar agreements with other developing countries that are great polluting, a critical step to contain global warming and avoid a full -fledged climate catastrophe.

Developing Nations politicians will notice the promise to finance a coal transition because South Africa is among the most dependent nations in the world in the world.

Vulnerable countries ask for help

The second day of the leaders' Summit at COP26 saw a series of emotional speeches from leaders from African and small island countries.

The Vulnerable Climate Forum (CVF), a group that joins the 48 countries with the highest risk of climate change, summoned a meeting at COP26 on Tuesday, asking the rich world to help them in the transition to green economies and deal with theimpacts of temperature increase.

The CVF ambassador and former president of Maldives, Mohamed Nasheed, urged large and small countries to remain united and "not give up".

"It is extremely naive for leaders to say that people's jobs will save by limiting themselves to fossil fuels," he said."Now everyone is vulnerable, not just us, the small islands".

Group leaders had a similar refrain: although their countries are among the least pollutants in the world, they are in the first line of the climatic crisis.

"The IPCC shows that Africa is heating faster than any continent in the world, although we are the least emitters," Ghana president Nana Akufo-Addo said in the forum, referring to the intergovernmental panel on climate change of the climate change of theUN."That is why we support the African group and the CVF to ask developed countries to lead emissions mitigation.".

Kerry also attended the meeting.Although he recognized the difficulties faced by vulnerable countries, he also urged them to act on the weather and reduce their own emissions.

"I will be very direct with you.Your complaint about what brought us here is legitimate.The future will be defined, but what we choose to do, "Kerry said."If we are going to be responsible before ourselves in the world, we have to reduce emissions and we also have to be responsible doing enough for adaptation to repair the damage and help countries to work on that".

More details about the plan against deforestation in COP26

The great promise of the COP26 to end deforestation by 2030, announced by more than 100 countries on Monday, began to take a clearer form when several governments announced concrete commitments.

The EU has promised € 1.000 million (US $ 1.100 million) to help protect the forests of the world over the next five years, a quarter of which will be reserved for the commitment of the Congo basin, an established background to protect the second largest tropical jungle in the world against threats.raised by industrial logging and mining.

The United Kingdom said that it would compromise £ 1.500 million (US $ 2.000 million) for five years to support the promise, including £ 350 million (US $ 475 million) for tropical forests in Indonesia and up to £ 300 million (US $ 408 million) destined for the Amazon.

And Biden promised US $ 9.000 million in the name of the United States.

"This plan is the first of its kind, adopts a complete government approach and works in our case with Congress to use up to US $ 9 billion in US funds until 2030 to preserve and restore our forests and mobilize billion billion more of our millions of ourpartners, "he said.
