Why Invest In Us. Even $5 Helps!

Since 2002, we have been the only California-wide group led by college students and alumni to collaboratively and nonviolently transform our colleges and communities into models of ecological, economic, and social sustainability.  We coordinated with more than 36 campuses and has trained thousands of students. 

Starting in 2017, we updated our mission to pressure decision-makers in any sector to act on the urgency of the climate crisis and prioritize equitable resiliency.

Your tax-deductible donation will be used wisely because we are a 501(c)(3) nonprofit project of the Earth Island Institute (EII).  EII provides governance and financial oversight for many activist organizations.  EII received the highest rating from Charity Navigator, America’s largest independent evaluator of non-profit organizations, for their efficient use of funds.

We Get Measurable Results

We Create Leaders

Before Emili Abdel-Ghany found CSSC, she came to the University of California (UC) Davis excited about environmental and social justice.  But she had never taken a leadership role.  At CSSC, she was really inspired to see older students invest in the leadership of younger students.   

So she created the CSSC Solidarity Organizing Program to train students to create a more equitable and sustainable world by being in solidarity with movements that create equality for people that are oppressed because of their race, gender, sexuality, or class.

Adopt A College Student

$30 provides one student with housing and food for a weekend at one of our semi-annual leadership retreats. 


If you donate $20 or set up a recurring donation, you’ll get a free subscription to the Earth Island Journal, an award-winning quarterly journal investigating many global environmental and social issues.
