US senators call on big oil to disclose suspected lobbying over Trump plan to axe key climate rule | Environment

In the wake of the Trump administration’s announcement, which he will cancel the rule that underlies almost all American climate regulations, a senatorial committee has launched an investigation into an alleged lobbying thrust that led to the decision.

On Tuesday, the Senate Environment and Public Works Committee sent letters to two dozen companies, including oil giants, thinktanks, law firms and commercial associations. The missives ask each company to submit documents concerning the 2009 Declaration, known as the endangering conclusion, that the Environmental Protection Agency (EPA) said in July that it would disilter.

The observation has devoted that carbon dioxide and five other greenhouse gases harm the health of Americans.

“Canceling the endangerment at the request of the industry is irresponsible, legally doubtful and deeply out of step with the main mission of the EPA to protect human health and the environment, and the American public deserves to understand your role in the advancement of the dangerous decision of the EPA,” wrote the senator of Rhode Island Sheldon Whitehouse, the committee member. “I am concerned about the role that fossil fuels companies, certain manufacturers, professional associations, groups supported by polluters and others with greatly benefit from the repeal of the conclusion of endangerment – including your organization – played in writing, preparation, promotion and lobbying on the proposal.”

Fossil fuel companies and their allies are threatened by the conclusion of endangering because it confirms in law that carbon dioxide, which their products produce, are dangerous, Whitehouse told Guardian. It also gives EPA the power to regulate these emissions under the Clean Act Act.

The letter, which requests all relevant private communications between the day Trump was re -elected in November until the day when the EPA announced its intention to cancel the conclusion of endangerment in July, was sent to the oil giants Exxon, Chevron, Shell and BP, as well as coal producers, a rail giant and two car manufacturers, whose affairs provide fossil foods.

“The only interests that benefit from the cancellation of the conclusion of endangerment are the interests of polluters, and in particular the interests of fossil polluters,” said Whitehouse.

It was also sent to professional associations and law firms representing large oil and automotive companies. And it was sent to the extreme right and to fuel fuel thinktanks Competitive Enterprise Institute, to New Civil Liberties Alliance, at the Heartland Institute, to the America First Policy Institute and to the Heritage Foundation, each dispute the authority of the federal agencies, and some of which have directly congratulated the proposal to endanger.

The Guardian contacted each recipient to comment.

Because the Republicans control the Senate, the Democrats on the Environment and Public Works Committee do not have the power to assign the documents. But the senatorial committee always expects companies to comply with their request.

The letter could send a signal to polluting sectors and right-wing companies that they are monitored, and could prepare the ground for a continuous investigation if the Democrats are watching a Congress Chamber in the mid-term elections next November.

The interests of fossil fuels rejected the conclusion of the endangerment during his first writing, but we know little about the more recent plea to overthrow him. Immediately after the Rollback EPA announcement, the New York Times reported that the groups had not “asked in recent years for its overthrow”. But Whitehouse thinks it changed since Trump was re -elected in November 2025.

When Joe Biden was president and the Democrats checked at least one Congress Chamber, Whitehouse said that “a request to cancel the endanger conclusion would have just looked like unnecessary and useless madness.

“But now that they can really do it in their despair and with the moderation mask made, I think it is very clear that they were directing this,” he said.

Under Trump, former lobbyists and lawyers for polluting industries such as petroleum, gas and petrochemicals have held management positions at EPA.

“The fossil fuels industry has and controls the Trump administration on all questions related to their industry, and they have subordinate republicans controlling both the room and the Senate,” said Whitehouse. “The change of power has allowed a change in tactics and attitude.”

Two environmental non -profit organizations continued the Trump administration for having “secretly” summoned a group of climatic opposites in order to strengthen its efforts to overthrow the conclusion of endangerment.

The update proposed by the EPA of the crucial legal conclusion is part of a more important war against the environment by the Trump administration, which killed dozens of climatic rules since its return to the White House in January.

“The reason is to help fossil fuels to survive,” said Whitehouse.
