CELF, a 501(c)3 not-for-profit corporation, was founded in 2003 to promote awareness of the importance of sustainability education and to help schools and school districts make sustainability an ongoing part of education.
We do this by providing consulting services for schools and school districts, training for teachers and administrators and sustainability education programs for students. We work with all kinds of schools—urban, suburban and rural, public and private. Our professional development programs are led by some of the most highly regarded authorities in the field.
