Scrapping the Engagement Finding: Payback for the Billionaire Climate Criminals

The February rollback of the "endangerment finding"—which provides the legal basis for regulating climate change—was many years in the works. It's the ultimate payback for a politically engaged fossil fuel industry and the climate criminals who use their wealth, power, and position to block efforts to help us transition to a post-oil, gas, and coal era.

Who's responsible for rolling back the endangerment finding? We believe it is time to name names so future generations—and future climate justice tribunals—will know who is responsible for incinerating our futures. Researchers at the Climate Accountability Research Project have tracked several of the key individuals working to undermine climate protection for the last two years

On February 12, 2026, Lee Zeldin, the head of the Environmental Protection Agency (EPA), announced the rescission of the 2009 Greenhouse Gas Endangerment Finding, repealing regulations for GHG emissions of motor vehicles. According to The New York Times, a small group of fossil fuel-funded right-wing operatives have pushed to roll back government regulation of greenhouse gases for the past 16 years and have finally succeeded. Myron Ebell, a leading climate denier and fellow at the libertarian think tank Competitive Enterprise Institute, stated that “no amount of public support would have done anything if there hadn’t been those four people: Russ and Jeff and John and Mandy.”

So who the heck are “Russ and Jeff, and John and Mandy?” Russell Vought, Jeffrey Clark, Mandy Gunasekara, and Jonathan Brightbill are well-known operatives within right-wing circles. For example, Russell Vought, President Donald Trump’s director of the US Office of Management and Budget, and Jeffrey B. Clark, former acting administrator of the Office of Information and Regulatory Affairs, are veterans from the first Trump administration.

Rolling back the endangerment finding will have devastating and irreversible consequences to the planet.

Clark has been fighting the government’s ability to regulate greenhouse gases since 2005. In 2022, Vought was vice president of the Heritage Foundation and managed Project 2025, the blueprint for many Trump initiatives. Vought hired Clark to draft executive orders for a future Republican president to easily reverse President Joe Biden’s climate initiatives. In 2023, Clark described climate change regulation as part of a plot to “‘meta control’ Americans.” Following the 2024 election, Vought and Clark were both asked to serve in Trump’s second administration where they were able to push for the repeal of the endangerment finding.

The “Mandy and Jonathan” are lesser known right-wing operatives. Mandy Gunasekara is an environmental attorney, former chief of staff for the EPA during the first Trump administration, and author of the Project 2025 report chapter on reforming the EPA. Gunasekara fought against policies from the Biden administration regarding emission reduction and self-identified as the “chief architect” behind Trump’s withdrawal from the Paris Agreement. The Climate Accountability Research Project identified Gunasekara as a Climate Criminal in 2024 because of her historical role in rolling back greenhouse gas regulations.

In 2015, Gunasekara infamously handed the late Sen. James Inhofe (R-Okla.) a snowball to use as a prop on the Senate floor as “proof” that climate change wasn’t a real threat. Gunasekara was serving as an aide to Sen. Inhofe, who was considered to be one of Congress’ most outspoken climate skeptics at the time. Gunasekara was also a former visiting fellow with the Heritage Foundation’s Center for Energy, Climate, and Environment, where she helped draft a policy agenda that “unleashes American energy production, and reduces barriers to economic freedom.”

Following Gunasekara’s resignation from the EPA in 2019, she founded the Energy45 Fund, a 501(c)(4) nonprofit organization “to promote the Trump energy agenda” and inform the public on the "environmental and economic gains made under the Trump administration.” The sources of funding for this organization have remained anonymous, and the organization has even been dubbed as a “dark money group” by Open Secrets.

In 2023, the Heritage Foundation published Project 2025, which featured Gunasekara’s 32-page chapter “Mandate for Leadership,” outlining a conservative agenda to move the EPA away from its focus on climate change. Key policy proposals outlined in her chapter include resetting scientific advisory boards, scaling back greenhouse gas regulation programs, and updating the 2009 endangerment finding. Gunasekara’s chapter also included the “Day One Executive Order,” which included a list of immediate actions to be taken on the first day of President Trump’s second term, with orders like “stop all grants to advocacy groups and review which potential federal investments will lead to tangible environmental improvements” and “revise guidance documents that control regulations such as the social cost of carbon.”

Jonathan Brightbill is currently the general counsel of the US Department of Energy. Brightbill argued against Obama-era climate policies while serving in the Justice Department in the first Trump administration.

In 2022, Gunasekara and Brightbill began their secret campaign to end the endangerment finding, in which they secured $2 million in funding from right-wing groups like the Heritage Foundation. The funding allowed Gunasekara and Brightbill to draft regulatory documents that would simplify the abandonment of the endangerment finding. Over the years, the two collected an “arsenal of information” to dispute the scientific evidence of climate change. The evidence collected along with their detailed plans of attack helped the Trump administration end the endangerment finding.

Rolling back the endangerment finding will have devastating and irreversible consequences to the planet. There will come a day, maybe sooner than we think, when climate criminals like “Russ and Jeff and John and Mandy” will be held to account.
