Support the Maryland Sierra Club

Clean Energy Rally MD Sierra Club group shot

We need your financial support in our fight to ensure all Marylanders have access to clean air, clean water, a healthy climate, vibrant sustainable communities, and access to the outdoors.  In today's political climate, state-based action is the best way to move towards zero waste, clean transportation and 100% renewable energy.   


Join the Sierra Club!

Donate to the Maryland Sierra Club Political Action Committee

There has never been a more important time to elect leaders who will fight for bold environmental solutions.  Through the Sierra Club PAC, we work to interview, endorse, and help elect state and local officials who will make the environment a top priority, to fight for clean air, clean water, and environmental justice. Every dollar given to the PAC is amplified by our amazing network of volunteers who contribute hundreds of hours of time organizing for strong leaders. The Maryland Sierra Club’s Political Program has a strong track record of helping elect dozens of environmental champions, informing candidates of critical issues, and raising money to elevate critical issues.
