CP solves better than the aff – it does all emissions not just carbon

Under a cap-and-trade program, laws or regulations would limit or ‘cap’ carbon emissions from particular sectors of the economy (or the whole economy) and issue allowances (or permits to emit carbon) to match the cap. For example, if the cap was 10,000 tons of carbon, there would be 10,000 one-ton allowances. A declining emissions cap would help reduce emissions over time.
Every source of emissions subject to the cap (for example, power plants or refineries) would be required to hold allowances equal to the emissions they produce. Power plant operators could acquire allowances through an auction (where they bid for the allowances they need) or allocation (where they are given a set number of allowances for free).
Once these entities have allowances, they would be able to trade or sell allowances freely among themselves or other eligible market participants. Because the allowances are limited and therefore valuable, those subject to the cap will try to cut their emissions as a way to reduce the number of allowances they have to purchase. The resulting interaction between the demand and supply of allowances in the market determines the price of an allowance (also known as the carbon price).
