Our Mission

Cities and companies are under increasing pressure to deliver Net Zero. 

But how can they accelerate their GHG emissions reductions and be held accountable with estimated, self-reported carbon data?

At Everimpact, we measure emissions precisely and in real time with satellites, sensors and AI.

This game-changing, certified data empowers cities and businesses to identify reduction opportunities and finance them through trusted carbon markets.

Our Story

Our three co-founders Mat, Alain and Jan have 80 years of cumulated experience in the United Nations. 

From setting up the first UN satellite agencies, capturing data for 50+ presidential elections, to advising the Green Climate Fund, they have managed complex projects on the most challenging global issues. ​

On the front line of war, food, health, flood, and drought crises, they also realised the urgency to tackle the root cause of climate change.

They set up Everimpact to collect the most accurate data on greenhouse gas emissions and help solve the greatest challenge of our times.
