• EPA to stop calculating money and lives saved by curbs on air pollution

  Agency to focus rules for fine particulate matter and ozone only on cost to industry, aligning with Trump approach

  The Environmental Protection Agency says it will stop calculating how much money is saved in healthcare costs avoided and deaths prevented from air pollution rules that curb two deadly pollutants.

  The change means the EPA will focus rules for fine particulate matter and ozone only on the cost to industry, part of a broader realignment under Donald Trump toward a business-friendly approach that has included the rollback of multiple policies meant to safeguard human health and the environment and slow climate change.

• US carbon pollution rose in 2025 in reversal of previous years’ reductions

  Study from research firm finds that US greenhouse gas emissions grew faster than economic activity last year

  In a reversal from previous years’ pollution reductions, the United States spewed 2.4% more heat-trapping gases from the burning of fossil fuels in 2025 than in the year before, researchers calculated in a study released on Tuesday.

  The increase in greenhouse gas emissions is attributable to a combination of a cool winter, the explosive growth of datacenters and cryptocurrency mining, and higher natural gas prices, according to the Rhodium Group, an independent research firm. Environmental policy rollbacks by Donald Trump’s administration were not significant factors in the increase because they were only put in place this year, the study authors said. Heat-trapping gases from the burning of coal, oil and natural gas are the major cause of worsening global warming, scientists say.

• Red-state Republicans seek climate ‘liability shield’ for fossil fuel industry

  If enacted, Utah and Oklahoma measures would restrict litigation against oil companies over role in climate crisis

  US lawmakers in two red states are attempting to shield the fossil fuel industry from climate liability.

  In Oklahoma, a newly introduced bill would bar most civil lawsuits against oil companies over their role in the climate crisis, unless plaintiffs allege violations of specific environmental or labor laws. A similar proposal in Utah would block lawsuits over climate-warming emissions, unless a court finds the defendant violated a statute or permit.

• US judge lets Danish firm resume Rhode Island offshore wind project halted by Trump

  Ørsted and other wind developers have faced repeated disruptions to multibillion-dollar projects under Trump

  A federal judge on Monday cleared the Danish offshore wind developer Ørsted to resume work on its nearly finished Revolution Wind project, which Donald Trump’s administration halted along with four other projects last month.

  The ruling by US district judge Royce Lamberth is a legal setback for Trump, who has sought to block expansion of offshore wind in federal waters.

• Trump’s move to pull US from key UN climate treaty may be illegal, experts say

  President’s memo stating US ‘shall withdraw’ from UNFCCC marks first time any country has tried to exit the agreement

  The Trump administration’s long-anticipated decision this week to pull the US from the world’s most important climate treaty may have been illegal, some experts say.

  “In my legal opinion, he does not have the authority,” Harold Hongju Koh, former head lawyer for the US state department, told the Guardian.
