California is the first state with a mandatory comprehensive cap-and-trade program. The program was introduced in 2012 to help the state lower its greenhouse gas emissions, by having businesses purchase permits for each metric ton emitted. Large companies that emit over 25,000 metric tons of carbon dioxide must comply with the cap-and-trade program. The permits companies have to purchase once they fall under the program are called allowances, and for every additional ton, an allowance must be purchased.

All of the allowances available under the program is equal to the cap for that year and every consecutive year the cap declines, and allowances become scarcer.
