About this game

The clock is ticking - as disasters rage, how will you stop the climate crisis? Unite the world through consensus or take aggressive action. Guide unique political factions with their own pros and cons. Reach global net zero or go it alone in this grand strategy game set on an Earth-like planet.

Climate Countdown

Global emissions are high.  Over time, disasters will only get more and more severe.  While you work to decarbonize, take measures to adapt and limit the damage.

Congress of Nations

Lead the world with your vision - propose global solutions and undertake complex negotiations to see them through.  Build alliances and influence unfriendly countries to see things your way.

Strategic Drawdown

There are many paths to net zero.  Research advanced technology to build clean energy and remove carbon from the atmosphere. Alternatively, take a more ecological route by bolstering natural carbon sinks and cyclical production.

Marketplace of Ideas

16+ different political factions compete for control in your nation.  Which will you favor and which will you push aside? Each has bonuses and limitations that make every playthrough a unique challenge.
