Allowance trading is a market-based approach that allows firms to buy and sell permits or allowances for emissions, enabling them to meet regulatory limits on pollution in a cost-effective manner. This system incentivizes reductions in emissions by allowing entities that can cut emissions at a lower cost to sell their excess allowances to those facing higher costs, thus promoting economic efficiency and flexibility in achieving environmental goals.
