好像是和碳排放權(quán)交易類似的概念,英文不太好![]() bubble concept :Pollution control concept that the atmosphere may be thought of as a glass bubble over a single source of air pollution. Therefore, the thinking goes, a facility may increase the amount of its emissions if another facility decreases its emissions by the matching amount. See also emissions trading. emissions trading :Tradable-permit system in which a greenhouse gases emitter (firm or country under obligation to limit its total air pollution emissions to a specified level) can buy/sell permission to emit a certain amount of emissions from/to other emitters (who are below/above their limit). The market price of these permits (called 'pollution credits') reflects the marginal cost of emission reduction and gives an emitter the incentive to install and manage a cost effective pollution control system as an income producing asset. Accumulating emissions reductions for trading is called 'banking.'
