A Times investigation revealed a coordinated effort by state treasurers to use government muscle and public funds to punish companies trying to reduce greenhouse gases.

Nearly two dozen Republican state treasurers around the country are working to thwart climate action on state and federal levels, fighting regulations that would make clear the economic risks posed by a warming world, lobbying against climate-minded nominees to key federal posts and using the tax dollars they control to punish companies that want to reduce greenhouse gas emissions.

Over the past year, treasurers in nearly half the United States have been coordinating tactics and talking points, meeting in private and cheering each other in public as part of a well-funded campaign to protect the fossil fuel companies that bolster their local economies.

Last week, Riley Moore, the treasurer of West Virginia, announced that several major banks — including Goldman Sachs, JPMorgan and Wells Fargo — would be barred from government contracts with his state because they are reducing their investments in coal, the dirtiest fossil fuel.

Mr. Moore and the treasurers of Louisiana and Arkansas have pulled more than $700 million out of BlackRock, the world’s largest investment manager, over objections that the firm is too focused on environmental issues. At the same time, the treasurers of Utah and Idaho are pressuring the private sector to drop climate action and other causes they label as “woke.”

And treasurers from Pennsylvania, Arizona and Oklahoma joined a larger campaign to thwart the nominations of federal regulators who wanted to require that banks, funds and companies disclose the financial risks posed by a warming planet.

At the nexus of these efforts is the State Financial Officers Foundation, a little-known nonprofit organization based in Shawnee, Kan., that once focused on cybersecurity, borrowing costs and managing debt loads, among other routine issues.

Then President Biden took office, promising to speed the country’s transition away from oil, gas and coal, the burning of which is dangerously heating the planet.

The foundation began pushing Republican state treasurers, who are mostly elected officials and who are responsible for managing their state’s finances, to use their power to promote oil and gas interests and to stymie Mr. Biden’s climate agenda, records show.
