Cap-and-Trade:A system where the government sets a limit (cap) on the total amount of a pollutant that can be emitted, and then issues a limited number of permits or allowances that allow the holder to emit a certain amount. Entities can then buy and sell these permits on a market.
Emissions Trading:A market-based approach to controlling pollution where companies or other entities are given or can buy and sell emissions permits. The total number of permits is limited, creating a market price for the right to emit pollution.
Pollution Permits: Permits or allowances issued by the government that give the holder the right to emit a certain amount of a pollutant. These permits can be traded on a market, allowing companies to buy and sell the right to pollute.
