A community of developers, engineers, and builders using their tech skills to fight the climate crisis. No suits. No greenwashing. Just code.
Every line of code that models emissions, optimizes energy, or helps communities adapt — matters. Build in the open. Share what you learn.
We expose greenwashing, hold polluters accountable, and build tools that make the invisible visible. Data as activism.
Skills compound when shared. Mentorship, sprints, and real projects — a mycelium network of climate technologists worldwide.
The systems destroying our climate — energy grids, supply chains, financial markets — are deeply technical. So the people fixing them need to be too. We believe technologists have a moral obligation to apply their skills to the hardest problem humanity has ever faced.
Climate Hacktivists is not a non-profit. Not a think tank. Not a conference. It's a network of people who ship things. People who believe that the right pull request, deployed at the right moment, can be as powerful as any protest.
You bring the skills. We provide the network, the projects, and the urgency.
Sign up, tell us your stack and interests. Instantly connect with hacktivists in your city and discipline.
Browse open projects — from wildfire detection models to grid optimization APIs. Find where you can contribute most.
Join sprint cycles, pair with mentors, ship real software used by real organizations fighting the climate crisis.
Every project tracks real-world outcomes. Know exactly how many tons of CO₂ your code has helped avoid.
Be part of the community that's building the tools, models, and systems the planet needs. Earth Day 2026 — no better time to start.
