On power plant emissions, Fervo, and a UK nuclear plant
Current conditions: A week into Atlantic hurricane season, development in the basin looks “unfavorable through June” • Canadian wildfires have already burned more land than the annual average, at over 3.1 million hectares so far• Rescue efforts resumed Wednesday in the search for a school bus swept away by flash floods in the Eastern Cape province of South Africa.
EPA
The Environmental Protection Agency plans to announce on Wednesday the rollback of two major Biden-era power plant regulations, administration insiders told Bloomberg and Politico. The EPA will reportedly argue that the prior administration’s rules curbing carbon dioxide emissions at coal and gas plants were misplaced because the emissions “do not contribute significantly to dangerous pollution,” per The Guardian, despite research showing that the U.S. power sector has contributed 5% of all planet-warming pollution since 1990. The government will also reportedly argue that the carbon capture technology proposed by the prior administration to curb CO2 emissions at power plants is unproven and costly.
Similarly, the administration plans to soften limits on mercury emissions, which are released by burning coal, arguing that the Biden administration “improperly targeted coal-fire power plants” when it strengthened existing regulations in 2024. Per a document reviewed by The New York Times, the EPA’s proposal will “loosen emissions limits for toxic substances such as lead, nickel, and arsenic by 67%,” and for mercury at some coal power plants by as much as 70%. “Reversing these protections will take lives, drive up costs, and worsen the climate crisis,” Climate Action Campaign Director Margie Alt said in a statement. “Instead of protecting American families, [President] Trump and [EPA Administrator Lee] Zeldin are turning their backs on science and the public to side with big polluters.”
Fervo Energy announced Wednesday morning that it has secured $206 million in financing for its 400-megawatt Cape Station geothermal project in southwest Utah. The bulk of the new funding, $100 million, comes from the Breakthrough Energy Catalyst program.
Fervo’s announcement follows on the heels of the company’s Tuesday announcement that it had drilled its hottest and deepest well yet — at 15,000 feet and 500 degrees Fahrenheit — in just 16 days. As my colleague Katie Brigham reports, Fervo’s progress represents “an all too rare phenomenon: A first-of-a-kind clean energy project that has remained on track to hit its deadlines while securing the trust of institutional investors, who are often wary of betting on novel infrastructure projects.” Read her full report on the clean energy startup’s news here.
The United Kingdom said Tuesday that it will move forward with plans to construct a $19 billion nuclear power station in southwest England. Sizewell C, planned for coastal Suffolk, is expected to create 10,000 jobs and power 6 million homes, The New York Times reports. Sizewell would be only the second nuclear power plant to be built in the UK in over two decades; the country generates approximately 14% of its total electricity supply through nuclear energy. Critics, however, have pointed unfavorably to the other nuclear plant under construction in the UK, Hinkley Point C, which has experienced multiple delays and escalating costs throughout its development. “For those who have followed Sizewell’s progress over the years, there was a glaring omission in the announcement,” one columnist wrote for The Guardian. “What will consumers pay for Sizewell’s electricity? Will it still be substantially cheaper in real terms than the juice that will be generated at Hinkley Point C in Somerset?” The UK additionally announced this week that it has chosen Rolls-Royce as the “preferred bidder” to build the country’s first three small modular nuclear reactors.
The European Union on Tuesday proposed a ban on transactions with Nord Stream 1 and 2 as part of a new package of sanctions aimed at Russia, Bloomberg reports. “We want peace for Ukraine,” the president of the European Commission, Ursula von der Leyen, said at a news conference in Brussels. “Therefore, we are ramping up pressure on Russia, because strength is the only language that Russia will understand.” The package would also lower the price cap on Russian oil to $45 a barrel, down from $60 a barrel, von der Leyen said, as well as crack down on Moscow’s “shadow fleet” of vessels used to transport sanctioned products like crude oil. The EU’s 27 member states need to unanimously agree to the package for it to be adopted; their next meeting is on June 23.
The world’s oceans hit their second-highest temperature ever in May, according to the European Union’s Earth observation program Copernicus. The average sea surface temperature for the month was 20.79 degrees Celsius, just 0.14 degrees below May 2024’s record. Last year’s marine heat had been partly driven by El Niño in the Pacific, so the fact that the oceans remain warm in 2025 is alarming, Copernicus senior scientist Julien Nicolas told the Financial Times. “As sea surface temperatures rise, the ocean’s capacity to absorb carbon diminishes, potentially accelerating the build-up of greenhouse gases in the atmosphere and intensifying future climate warming,” he said. In some areas around the UK and Ireland, the sea surface temperature is as high as 4 degrees Celsius above average.

The Pacific Island nation of Tonga is poised to become the first country to recognize whales as legal persons — including by appointing them (human) representatives in court. “The time has come to recognize whales not merely as resources but as sentient beings with inherent rights,” Tongan Princess Angelika Lātūfuipeka Tukuʻaho said in comments delivered ahead of the U.N. Ocean Conference in Nice, France.

Facing the threat of legal challenges from the Trump administration, California’s South Coast Air Quality Management District, a regional agency that regulates pollution, voted on Friday to reject proposed rules to reduce sales of gas-fired furnaces and water heaters. The rules would have required manufacturers to gradually increase the proportion of zero-emissions appliances like heat pumps that they sell to 90% by 2036, and put surcharges on gas equipment. The standard took two years to draft and bring to a vote but was fiercely attacked by the gas lobby, which labeled it a “gas ban.”
The Department of the Interior approved the expansion of the Bull Mountains coal mine in Montana on Friday, cutting short its environmental review process and allowing the mine to operate for nine more years. Interior Secretary Doug Burgum cited Trump’s energy emergency declaration, saying that it “is allowing us to act decisively, cut bureaucratic delays and secure America’s future through energy independence and strategic exports.” The mine exports its coal to Japan and South Korea. My colleague Jael Holzman has covered the administration’s efforts to speed mining approvals, including for projects that may not be economically viable.
Trump signs executive orders related to nuclear in May.in McNamee/Getty Images
In an interview published Sunday, Dan Sumner, the CEO of Westinghouse, told the Financial Times that the company is talking to the Trump administration about building 10 new AP1000 nuclear reactors. The news follows an executive order Trump issued in May setting a goal of starting construction on 10 such large, conventional reactors in the next five years. The last AP1000 built in the U.S., at the Vogtle Electric Generating Plant in Georgia, took 15 years to complete. As my colleagues Matthew Zeitlin and Katie Brigham explained in a recent piece, however, between the complex licensing process and an underdeveloped workforce and supply chain, it will be tough to speed things up.
The third United Nations ocean conference kicks off today in Nice, in the South of France, and the U.S. is not in attendance. Delegates, scientists, and environmental advocates from around the world are gathering to advance global cooperation to protect the ocean from global warming, plastic pollution, and overfishing. During a pre-conference event on Sunday, French prime minister Emmanual Macron called for global moratorium on deep-sea mining, and said 30 countries were ready to commit to it. “I want us to reach an agreement for the entire planet,” he said. “It’s completely crazy to go and exploit, to go and drill in a place we don’t know. It’s frenzied madness.”
A raft of provisions for Trump’s budget bill put out by the Senate Commerce Committee last week included a rollback of the Corporate Average Fuel Economy Standards. The proposal would eviscerate “one of the federal government’s longest-running programs to manage gasoline prices and air pollution,” writes Heatmap’s Robinson Meyer, by setting all fines levied on noncompliant automakers under the program to zero dollars. But Ann Carlson, a UCLA law professor who led the National Highway Traffic Safety Administration from 2022 to 2023, told Robinson that she doubted the change would make it through the Senate’s strict rules that enable it to pass the budget with a simple majority.
Senators Bill Cassidy, Shelley Moore Capito, and Susan Collins are among the more than four dozen members of Congress who have stayed at a Lake Como villa owned by the Rockefeller Foundation to talk climate change and energy policy — on the nonprofit Aspen Institute’s dime, reports NOTUS.
