"The environmental group gave up its singular focus on climate change for a broader agenda. The ensuing internal strife left it weakened as it takes on the Trump administration."

"The Sierra Club calls itself the “largest and most influential grass roots environmental organization in the country.” But it is in the middle of an implosion — left weakened, distracted and divided just as environmental protections are under assault by the Trump administration.

The group has lost 60 percent of the four million members and supporters it counted in 2019. It has held three rounds of employee layoffs since 2022, trying to climb out of a $40 million projected budget deficit.

Its political giving has also dropped. Federal campaign-finance records show $3.6 million in donations from the Sierra Club during the push to defeat Donald J. Trump in 2020, but none as Mr. Trump stormed back to the presidency in 2024.

And this year, as the Trump administration returned better organized and better prepared than in its first term, the Sierra Club was the opposite. While Mr. Trump boosted coal power, canceled wind farms and rolled back pollution limits, the club was consumed by internal chaos, culminating when the board fired its executive director, Ben Jealous, a former president of the N.A.A.C.P."
