The Achilles’ Heel of Biden’s Climate Plan? Coal Miners.

Unions representing other workers affected by climate legislation have struck deals, but opposition from coal miners has persisted, complicating the path to enactment.

For years, environmentalists have sought compromises with labor unions in industries reliant on fossil fuels, aware that one of the biggest obstacles to cutting carbon emissions is opposition from the unions’ members.

States like Washington, New York and Illinois have enacted renewable-energy laws that were backed by unions representing workers who build and maintain traditional power plants. And unions for electricians and steelworkers are rallying behind President Biden’s climate and social policy legislation, now in the Senate’s hands.

But at least one group of workers appears far less enthusiastic about the deal-making: coal workers, who continue to regard clean-energy jobs as a major risk to their standard of living.
