Cap-and-Trade Resources
Find out how OPIS handled Cap-and-Trade regulations.

On August 1, 2014, OPIS began providing price discovery for the California carbon market in its U.S. West Coast Spot Market Report, estimating the impact of the state's cap-and-trade regulations on transportation fuels delivered at the rack level. This includes daily price discovery for California Carbon Allowances (CCA) and a daily California Cap-at-the-Rack (CAR) assessment. On October 1, 2014, OPIS began publishing CAR price assessments for gasoline, diesel fuel and biodiesel in the OPIS California Rack Reports.
