The Oakland-based Sierra Club is suddenly battling in court as well as in the climate arena, after a former foundation director filed suit accusing the group’s charitable arm of systematically forcing out Black leaders. The complaint drops into an already tense moment for the organization, following a series of disputed leadership departures, including the 2025 firing of Executive Director Ben Jealous. Together, the turmoil has stoked sharp questions about who holds power inside one of the country’s oldest environmental groups and how it wields that power. Community and labor leaders are already calling for outside scrutiny.
The complaint and who filed it
According to AP, Pedro da Silva, former head of the Sierra Club Foundation’s Shifting Trillions program, filed a lawsuit in Alameda County on Jan. 29, 2025. The complaint lists 13 causes of action, including discrimination, retaliation and wrongful termination. Da Silva says he worked for the foundation from May 2023 until he was fired in February 2025, and alleges he was promised staff and resources that never materialized while his role was steadily sidelined. The foundation has rejected his claims, and the case is now moving through California state court.
What the suit alleges
The lawsuit portrays what it calls a broader pattern of institutional behavior that allegedly left Black professionals isolated and ultimately pushed out through internal investigations and personnel procedures. E&E News reported that the filing argues these investigations became a mechanism to remove employees of color. The complaint cites specific staff members and incidents that it claims illustrate that pattern.
A string of contested exits
The legal fight lands on top of a messy run of leadership changes inside the Sierra Club. The board put Executive Director Ben Jealous on leave in July 2025 and then voted to fire him in August 2025, according to the Los Angeles Times. Around the same time, a senior strategy officer resigned in early 2025 after reporting revealed he was registered as a lobbyist for a cryptocurrency firm, a departure covered by Inside Climate News. Together, the shakeups pulled what might have been internal HR drama into the realm of a very public governance brawl.
Board rules and low-turnout elections
Some leadership changes can be chalked up to standard board churn and three-year terms. But the club’s internal rules and voting habits have raised the stakes for every open seat. A 2022 inspectors’ report showed that 52,924 valid ballots were returned out of about 695,607 sent to members, or roughly 7.61% turnout, according to Grassroots Choice. That thin participation, layered on top of organized candidate slates and overlapping roles between the club and its foundation, has made each director’s chair unusually powerful, a dynamic described in reporting republished by Atlanta Daily World.
Voices calling for review
Labor and civil-rights figures are pressing for an independent look under the hood. The Progressive Workers Union, which represents a large share of Sierra Club staff, has issued public statements calling for accountability and arguing that the leadership shakeup should open the door to stronger worker-management relations. Civil-rights leader Rev. Al Sharpton has also urged outside mediation in the wake of Jealous’s firing, according to Black Enterprise.
Legal implications
If the lawsuit moves ahead, it could lead to depositions and document discovery that pull back the curtain on internal decision-making at both the foundation and the club, according to coverage in E&E News. The foundation has denied that it discriminated, and the case will continue in Alameda County Superior Court unless the parties reach a settlement.
For Oakland and the broader environmental world, the outcome may reveal whether the Sierra Club can deliver clear answers while keeping its advocacy work on track. Observers say the key things to watch now are any new filings in state court, whether the organization agrees to an independent review or mediated process, and how local chapters and rank-and-file members react to potential governance changes, as recently reported by Inside Climate News.
