The Carbon Doctrine
Shape the world through 2050
Free · Designed for iPad. Not verified for macOS.
Govern a great power through climate crisis, geopolitical rivalry, and the hard trade-offs that shape the world of 2050.
You govern one powerful region. You do not control the world.
Lead the United States or European Union from 2026 to 2050 in a geopolitical climate strategy game about power, money, technology and force.
Every crisis response and governing action strengthens an emerging doctrine. Delay hard choices. Protect fossil growth. Decarbonize at home. Spend where each dollar removes the most carbon. Gamble on technological salvation. Or use trade and military power to coerce burden-sharing.
Five autonomous world blocs pursue their own development, energy and security interests. They react to your financing, credibility, tariffs, technology and threats—but they do not obey you.
