A free online simulator that shows how policy and technology choices change global temperature, energy use, health and GDP.
For students, teachers, campaigners and anyone who wants to test which climate solutions matter most.
Why it’s listed
It's built by Climate Interactive with MIT Sloan (1), with a public technical reference updated in September 2026 (2). New model releases come most months, the latest on 2 September 2026 (3).
The trade-off
It models the whole world, so it won't tell you your personal footprint; Climate Interactive's legal form wasn't verified today.
Price
