If that happens, the U.S. will catch up. Under the Paris agreement, the United States has promised to cut emissions by about 25 percent from 2005 levels by 2025, but the country is only on track to cut about 17 percent, analysts said. So if it becomes the only country to withdraw from a global solution to a global problem, it raises questions of trust. The United States is now the only country to withdraw from the pact. After years of negotiations, the signatories of the Paris agreement have decided to try to limit global warming to less than 2 degrees Celsius by the end of the century and aim for an even more ambitious target of 2.7 degrees Fahrenheit (1.5 degrees Celsius). Exceeding these thresholds, suggested mountains of science, would lead to catastrophic changes in the climate system, which would have dangerous and costly consequences for billions of people around the world. Since the agreement, a continuous stream of research has shown that even the goal of lowering temperatures should produce unwelcome effects. Many of them are already evident, from busy tropical cyclones to record wildfires. Last year, according to the EPA, the United States recorded a 10% decrease in emissions compared to 2005, far from the Paris targets. This year, the significant impact of the pandemic has already significantly reduced U.S. emissions, which appears to be a country close to its goal.
But the costs were enormous. The U.S. withdrawal has not only harmed climate protection in the United States, but also the agreement as a whole. “It has created a leadership vacuum, leaving doors open for more reduced voices [in UN climate talks] with some actors strengthened by the Trump administration,” Kizzier says. It has also helped to reduce the ambitions of some of the Paris signatories, she adds, as many countries have failed to shift their emissions targets as they had planned this year. Nevertheless, achieving the goals of the Paris climate agreement remains an important task. 30 years later today, it is one thing to set a pole of goals and make another, to start implementing plans. Each country will still have to deal with its own domestic policy problems, and other major countries, such as India, the world`s third largest emitter of greenhouse gases, will have to set more aggressive limits for carbon dioxide. But with the U.S. on board, the world has a better shot to contain climate change. But the idea of the Paris agreement was to encourage everyone to agree on a common goal and strengthen their commitments over time, with regular international meetings to see where all are and to develop the painful rules for measuring progress. So far, this has not been enough to keep the world on track to achieve the goals of the agreement.
Not quite. In response to Trump`s exit from the agreement, other players have stepped up to make climate commitments. More than 500 cities and counties in the United States and 25 state governors have formed a coalition with thousands of businesses, universities and others that, in accordance with the Paris agreement, are working to reduce emissions at the local level. This group now accounts for “nearly 70 percent of U.S. GDP” and 65 and “more than half of U.S. greenhouse gas emissions,” according to the U.S. promise, the coalition that brings these units together.
