Who We Are

We are united by a desire to activate the potential of America’s K-12 public school sector to respond to the challenge of climate change and are undaunted by the scale of the challenge. We believe the current moment offers an opportunity for bipartisan action to address longstanding inequities, stimulate the economy, enhance critical public infrastructure, and position America to lead the world in the transition to clean energy-driven commerce and community.

Our Vision

Every dollar spent on K-12 infrastructure is aligned with building an equitable, zero-carbon, climate-resilient future. Every education leader recognizes that rapidly changing climate threatens their core mission. Every student is prepared to build a sustainable future in a rapidly changing climate.
