2025 IN REVIEW
Two million people, one shared mission
In 2025, ClimateHero passed a milestone we once only dreamed of: more than two million people have now used our climate calculator to understand their footprint and commit to reducing it, on average by around 30% each. Together, that adds up to 4 million tonnes of CO₂e reduced annually through real behavior change. Available in seven languages and used across 165 countries, the movement is only growing.
