Environmental Politics and Policy
Cap-and-trade systems are market-based environmental policies that set a limit (cap) on greenhouse gas emissions while allowing companies to buy and sell allowances for those emissions. This approach incentivizes companies to reduce their emissions by creating a financial motive—firms that reduce emissions below their allowance can sell their excess permits, while those that exceed their limits must purchase additional allowances. By establishing a clear limit and facilitating trade, these systems aim to reduce overall pollution effectively and efficiently.
