Sierra Club Washington State Chapter

The Sierra Club's members and supporters are more than 3.8 million of your friends and neighbors. Inspired by nature, we work together to protect our communities and the planet. We’re America's oldest, largest and most influential grassroots environmental organization.

The Sierra Club Washington State Chapter is a team of staff and volunteers working to empower our communities to tackle a broad array of environmental challenges across the state. The work we do ranges from protecting wilderness to fighting climate change; from advocating for clean water for people and fish, to rallying our neighbors to stop new fossil fuel projects in their tracks. We organize diverse activities such as hikes, community rallies and political campaigns to achieve our goals. Join in and help us protect our air, land and water throughout our beautiful state!
