World leaders have announced new goals to reduce greenhouse gas emissions at the United Nations, aiming to revive global climate efforts. This comes just a day after Donald Trump dismissed climate change as “the greatest con job ever perpetrated upon the world.”
On Wednesday, 120 countries and the European Union pledged to cut emissions in New York. Notably, China, the world’s largest emitter, committed to reducing its emissions by 7–10% from their peak by 2035.
UN Secretary-General António Guterres, who organized the special summit, urged nations to act “much further, much faster,” as most are falling behind in meeting agreed temperature targets. He warned that the goal of limiting global warming to 1.5°C (2.7°F) is at risk of collapsing.
Guterres called for the upcoming UN climate talks in Brazil, known as COP30, to produce a credible global plan to get back on track. “The science demands action, the law commands it, the economics compel it, and people are calling for it,” he said, referencing a recent international court ruling.
So far, few countries have submitted updated emission reduction plans ahead of the November COP30 talks, which are intended to set new targets to combat worsening heatwaves, droughts, and floods. Current projections show the planet is headed for up to 3°C (5.4°F) of warming—far beyond the 1.5°C limit set in Paris—which would have catastrophic consequences.
The global effort has been further complicated by the United States, historically the largest carbon emitter. In a speech to the UN on Tuesday, Trump spread misinformation, rejected climate science, and criticized the shift to clean energy. He claimed the “green energy agenda” is destroying countries, called climate science a “hoax,” and described wind turbines as “pathetic.” He also revealed he has urged countries like the UK to drill for more oil.
“Your country is going to fail if you don’t get away from this green scam,” Trump said. “You need strong borders and traditional energy sources to be great again.”
Trump’s long-standing denial of climate change—evidenced by his rollback of environmental regulations, withdrawal from the Paris Agreement, and blocking of clean energy projects—was quickly condemned. Manish Bapna of the Natural Resources Defense Council responded, “Anyone looking outside their window knows climate change is here. The real question is why any responsible leader would try to convince us otherwise.”
Climate advocates at the UN General Assembly and Climate Week events in New York emphasized that the world must move forward with or without U.S. leadership under Trump, accelerating the transition to renewable energy. Last year, global investment in renewables like solar and wind reached $2 trillion—double the amount spent on fossil fuels.
Rachel Kyte, the UK’s climate envoy, encouraged focus on the benefits of clean energy: “All of the jobs, all of the opportunity is there. Don’t get distracted by the noise. Follow the signal, and I think we’ll get there.”195 countries have ratified the Paris Agreement, and with one withdrawal, that leaves 194 still committed—not zero. While some may try to undermine or threaten the agreement, 194 countries are coming to Belém to keep the effort moving forward.
Among these nations, China will be a major focus. It accounts for about a third of global emissions but has also become the world’s leading clean energy superpower. On Wednesday, President Xi Jinping announced that China plans to install more than six times as much wind and solar capacity by 2035 compared to 2020 levels.
Former US Vice President Al Gore expressed concern, saying, “It’s a great tragedy that the United States is holding itself back and allowing China to take the lead in addressing the climate crisis.” However, Gore remains optimistic that the world will choose clean energy over the fossil-fuel revival supported by Trump. “We are going to win this struggle,” he said. “The only question is whether we will do it in time to avoid the worst consequences.”
Despite recent emissions reduction pledges, known as nationally determined contributions (NDCs), the world is still on track to exceed the 1.5°C warming limit—a threshold that vulnerable countries view as an existential threat. Tina Stege, climate envoy for the Marshall Islands, noted that many pledges fall short: “There has to be an honest assessment that they won’t be enough. We already know these efforts won’t get us where we need to be.”
In November, governments will meet in Belém, Brazil, to address this gap, though attendance may be limited due to a shortage of hotel rooms in the Amazon city. Juan Carlos Navarro, Panama’s environment minister, described the logistics of COP30 as “a nightmare” and expressed little hope for a positive outcome. “To be frank,” he said, “I’ve seen a lot of hot air and very little progress.”
