To meet the Paris agreement, the world would have to eliminate 53.5 billion metric tonnes of carbon dioxide each year for the next 30 years. This column proposes a plan to meet the costs of this in an equitable way. Countries that contribute most to the stock of GHGs could issue an instrument that gives investors in projects anywhere in the world that reduce emissions the right to borrow from them at their overnight interest rates – which are currently near zero – and to roll over this borrowing for as long as the project delivers some minimum rate of reduction in emissions per dollar invested. Luckily, such an instrument already exists in the form of the IMF’s Special Drawing Rights.
