Presidents, politicians, diplomats and scientists descended on Brazil this week to open the international climate summit known as COP30. Although California’s governor made headlines with his remarks, there is no official U.S. delegation, marking the first time that the world’s largest economy — and historically the world’s largest carbon emitter — has refused to participate in global efforts to reduce the harm of climate change.
On one level, America skipping out on the multilateral talks places a ceiling on just how much effect any commitments made at the conference will have on reducing carbon emissions globally. But in Trump’s second term, America has transformed from a potential roadblock during climate talks into an aggressive antagonist. By pulling back from the discussions underway in Belém, President Donald Trump may have given them a greater chance of success than otherwise would have existed.

It was clear before Trump returned to office that clean-energy technology was not part of his agenda. A centerpiece of his campaign was denouncing the “Green New Scam,” as he called it, promising to roll back the Biden administration’s climate achievements and investments in renewable energy. In its place would be a set of policies campaign officials described as working to “maximize fossil fuel production” — or, in Trump’s words, “drill, baby, drill.”
Two years ago, as another round of climate talks began, I described those Trump campaign proposals as plans to “kill us all even faster.” Amazingly, that might have been an understatement, because for the Trump administration’s strategy for American energy dominance to succeed, global moves away from fossil fuels must be kneecapped. Rather than merely ignoring the rest of the world’s efforts to forestall rising temperatures as we make polluters great again at home, what little progress other countries have made must also be rolled back.
Accordingly, U.S. diplomats have begun impeding multilateral efforts to address climate issues. Last month, the United States tanked an International Maritime Organization deal that would have required global shipping vessels to reduce their emissions or be forced to pay a fee. The treaty was all but done when the Trump administration swooped in, threatening economic sanctions against countries that agreed to the pact as well as pledging to turn away their ships from American ports. Similarly, long-running discussions to set a limit on global plastic pollution were scuttled this summer in the face of administration obstinance. As The Washington Post noted, the plastics industry has become “a crucial growth market for fossil fuel companies at a time when solar power and electric vehicle uptake is expected to eat into demand.”
