Throughout Orange and Los Angeles Counties groups of Sierra Club members work together on many conservation projects and environmental concerns and give voice to efforts to protect open spaces and wild habitats.


Clean Air, Water & Energy

We will continue to organize and mobilize to restore the right to clean air and clean water and build sustainable communities powered by clean, renewable energy.

Coastal Preservation

Our coastal campaigns and committees work with state and local agencies to protect and preserve our coastal habitats and communities from the threats of pollution, development, and a changing climate.  

Open Space & Habitat Preservation

We play a pivotal role in developing the sustainable and just solutions necessary to protect our home’s natural beauty, wild creatures, and scenic landscape from the climate and extinction crisis
