A cap-and-trade system puts a limit on overall emissions, so that emitters have to pay a price for emitting. This price will, as shown in the figure above, equal the marginal benefit of the last unit of emissions allowed. The purpose of this page is to describe the differences between a carbon tax and carbon cap-and-trade policies using the most basic of all environmental economic models. Consider a polluting firm that faces an increasing marginal pollution abatement cost curve (click on the thumbnail for a larger picture). Cap and trade is the textbook example of an emissions trading program. Other market-based approaches include baseline-and-credit, and pollution tax. They all put a price on pollution (for example, see carbon price), and so provide an economic incentive to reduce pollution beginning with the lowest-cost opportunities.

The cap on greenhouse gas emissions that drive global warming is a firm limit on pollution. The cap gets stricter over time. The trade part is a market for companies to buy and sell allowances that let them emit only a certain amount, as supply and demand set the price. Trading gives companies a strong incentive to save money by cutting emissions in the most cost-effective ways.

13 Aug 2009 Economists behind the original concept of cap-and-trade question the system's large-scale usefulness, and recommend taxes instead. Market trading in these allowances establishes a price on emissions that in turn creates economic incentives for cost-effective abatement.1 It is common practice to  Emissions Trading. Cap and trade systems, like taxes, generate economic incentives to change the behaviour of societal actors and reduce pollution. But instead
