Capture City 2050

How to play, in one minute.

2050
Your goal

You run the power company of a coal-and-gas town. Keep the lights on every month until December 2050 while the law cuts the CO₂ you may emit, year after year, toward net zero.

CO₂
Watch out 1: the CO₂ limit

Keep the orange bar inside the green box. The box shrinks every year. Go over and the red limit-breach meter fills; at 100 % you lose your licence. Add CO₂ capture to your plants in time: it takes a year to build.

Watch out 2: public anger

High electricity prices, blackouts and smog make people angry. At 100 % you are voted out. Capture eats power, so plan spare plants for the summer or winter peak.

$
And keep some money

Electricity bills pay for everything: capture plants, research, CO₂ storage. Below −$500M you go bankrupt. The price board in the town sets the bill.
