Children's Environmental Literacy Foundation(CELF)

CELF is establishing sustainability as an integral part of every child’s K-12 learning experience. CELF has reached more than 1 million students by training more than 14,000 teachers in over 4,000 schools.

CELF was founded in 2003 on the principle that education for sustainability is essential for today’s K-12 students. Education for sustainability is a teaching methodology that develops critical thinking skills necessary to understand complex, interconnected issues. Students today face unprecedented challenges and an imperative to balance economic, social and environmental problems. They need to feel inspired and be prepared to innovate new solutions. CELF programs use real-world problem solving to prepare students with the holistic thinking skills and motivation to become agents of change for a healthier and sustainable future.
