The Economics of Controlling Stock Pollutants: An Efficient Strategy for Greenhouse Gases
应用最优控制理论,提出控制温室气体等存量污染物的有效策略:任何时刻的边际减排成本应等于未及时减排排放的边际损害现值,且随时间推移减排力度应逐渐减轻。当前需适度减排,未来需更大努力。
Optimal control theory is applied to develop an efficient strategy to control stock pollutants such as greenhouse gases and hazardous waste. The optimal strategy suggests that, at any time, the marginal costs of abatement should be equated with the present value of the marginal damage of timely unabated emission. The optimal strategy calls for increasingly light abatement over time as the pollutant stock accumulates. The optimal policy applied to greenhouse gases suggests moderate abatement efforts, at present, with the potential for much greater future efforts.
