What is RGGI?
The Regional Greenhouse Gas Initiative (RGGI) is a carbon cap and trade system. RGGI regulates the amount of CO2 the power plants in the Northeast United States are allowed to emit. RGGI reduces emissions by requiring power plants to hold a permit for each ton of CO2 they emit. Over time regulators reduce the number of permits available, thereby tightening the cap.
