Sustainable Claremont engages people in education and action to create a more sustainable community – environmentally, socially, and economically — in Claremont and beyond.

Who We Serve

Sustainable Claremont serves more than 37,000 residents of the City of Claremont as well as the neighboring cities of La Verne, Montclair, Pomona, Upland, and Rancho Cucamonga, and the greater Southern California region.

What We Do

Sustainable Claremont achieves its mission through education and action. Our community-based programs seek to engage those we serve and alleviate environmental injustices. These efforts create sustainable solutions that conserve, restore and protect resources such as climate, air, energy, trees, food, water, and wildlife. Our programs and services include:

  • The C. Freeman Allen Sustainability Resource Center
  • Green Crew Urban Forestry and Beautification Program
  • Environmental Education and Community Engagement Programs
  • Community Advocacy


The City of Claremont Sustainability Plan, adopted on October 28, 2008, recommended for the formation of a citizen group that would work with the City government – independently but in cooperation – on issues of environmental, social, and economic sustainability. In March 2009, Sustainable Claremont was formed as an independent 501(c)3 nonprofit organization. We’ve been working hard ever since to see our community grow and prosper as a Green City!
