Who Pays for the Warming?

Climate change is a shared problem with unequal causes and unequal effects. Rich countries have burned most of the fuel that warmed the planet, while some of the poorest places face the worst floods and droughts. Climate justice asks how the burdens should be shared.

Three common principles compete. The polluter-pays principle says those who caused the harm should bear its cost. The ability-to-pay principle says those with more should carry more. The beneficiary-pays principle says that those who gained from the pollution should pay.

Each principle has strengths and gaps, and many writers combine them. A fair plan can be tested with the question from The Veil of Ignorance: would you accept it if you did not know whether you would live in the valley or on the hill?

The flooded valley

Two neighboring towns share a river. The upstream town built a factory whose outflow floods the lower valley each spring. The valley town has little money.

At the regional meeting, the upstream mayor says the valley should build its own walls. A delegate asks which principle he is using. Under polluter-pays, the factory owner should pay, and the delegates agree on a fund paid by the upstream town.
