Excerpt from the Washington Post:
Under the cap-and-trade system, the federal government would limit the total volume of CO2 that U.S. companies can emit each year and would issue permits that companies would be required to have for each ton of CO2 emitted. Once issued, these permits would be tradable and could be bought and sold, establishing a market price reflecting the targeted CO2 reduction, with a tougher CO2 standard and fewer available permits leading to higher prices.
Companies would buy permits from each other as long as it is cheaper to do that than to make the technological changes needed to eliminate an equivalent amount of CO2 emissions. Companies would also pass along the cost of the permits in their prices, pushing up the relative price of CO2-intensive goods and services such as gasoline, electricity and a range of industrial products. Consumers would respond by cutting back on consumption of CO2-intensive products in favor of other goods and services.
