About Personal Carbon Ledger
Personal Carbon Ledger treats emissions the way a retail bank treats money: a monthly quota, a ring that fills as you spend it, and a running statement where every flight, train ride and grocery basket is debited in kg CO2e.
It draws on the real product surfaces of Doconomy, the 2030 Calculator, Klima and Plan A — white pages, a single brand green, figures set in a monospace grid — and pushes them to 2035, when the allowance is statutory and the balance can be traded.
