Climate activists protesting in Germany


We are a diverse group of over 3,800 passionate individuals who have come together to solve the greatest challenge of our time: the climate crisis.

Our Mission

We believe real change comes from the ground up. We know that a small-but-committed critical mass of activists can not only transform society, but change the world.

That’s why we recruit, train, and mobilize people to become powerful activists, providing the skills, campaigns, and resources to push for aggressive climate action and high-level policies that accelerate a just transition to clean energy.

Our Campaigns

We train and mobilize people around Europe with four global campaigns to accelerate climate action this decade and help us reach true net zero by 2050 - the point where global warming can stop in as little as three-to-five years and the Earth behind to heal.
