Those of us who are concerned about the escalating climate crisis may be surprised that the world’s major oil powers agreed to increase production last week.OPEC Talk about “Strengthen market fundamentals.” In the short term, maybe. But the cartel’s latest transaction cannot conceal the continuous destruction of its business case in the medium term.

Senior Market Analyst Mark Lewis debate Last year, we saw a peak in oil demand. Other experts have reached the same conclusion. We have seen the devastating effects of burning oil, natural gas and coal on our planet and humanity. Extreme weather events in the United States, Canada, Europe and other regions mean that the rich world that has been obsessed with oil for decades is now feeling the uncertainty that developing countries have suffered for years.

Heat waves and catastrophes call for a calm political mind to prevail. The good news is that we already have a plan. The Paris Agreement adopted by 196 countries in 2015 is a comprehensive framework for governments to cooperate in the greatest cause of mankind: to shift the global economy from fossil fuels to a cleaner, safer and healthier future.

In 100 days, the same 195 governments will hold COP26 in Glasgow, which is a necessary critical moment. According to the Paris Agreement, all countries must implement new and stricter emission reduction measures. This moment is full of challenges, but many people will remember the uncertainty that led to the finalization of the Paris Agreement. Collective interests prevail, not because it is easy, but because stubborn optimism unites world leaders against the common threat of climate change.

This stubborn optimism is why I will not be put off by the opposition of those with vested interests in expiring fossil fuels. We know that the window of opportunity is closing, and the only option is to do scientific requirements: eliminate fossil fuels and rebuild a flattened global economy.

The success of COP26 depends on three elements: First, all G20 countries must commit to reducing emissions At least 45 percentage. For the leaders of China, India, and Australia who have not yet achieved the 2030 goals, what I want to say is: It is in your economic self-interest to accelerate the transition from coal-fired power and start tackling looming traffic emissions. The green economy is the growth story of the 2020s: 35 million new green jobs It is expected to be 2030.

Second: The richest countries in the world must fulfill their promises. The United States, the European Union, the United Kingdom, Japan, and other G7 countries must propose financial delivery plans before the UN General Assembly in September to support fragile states.

Third: The CEOs of the world’s leading companies must face the reality that only by preventing crises can there be business continuity. For a long time, big companies have been talking about a good game while opposing decarbonization behind the scenes.We need them to appoint climate experts to their boards, disclose the climate risks they face, clean up their supply chains and read the International Energy Agency’s New net zero strategy. This must be their script for the next ten years, because this will be their government’s regulatory manual.

100 days is not long. British Prime Minister Boris Johnson must deploy all the means he can find to encourage large emitters to achieve goals consistent with the 1.5C trajectory. Now is not the time to doubt-we have to believe that No. 10 will do all these things that are needed.Signs of progress are everywhere-from a series of new carbon emission reduction policies in the United States and the European Union, to Climate Prosperity Plan From the finance ministers of the weaker 20 countries, as well as the ongoing innovations in the real economy.

The solution already exists today because the “Paris effect” has already begun. The next 100 days are all about timely delivery, and as promised, bold and decisive leadership is required. Every day is important.
