The California cap-and-trade system covers emissions from utility and industrial facilities, which emit more than 25,000 tonnes of carbon each year, and from entities that opted into the program. Those facilities must purchase either carbon allowances or carbon offsets to account for their annual emissions under the annual emissions cap. The cap is reduced annually until the 2020 target is reached.
