CO2 Emissions Washington Carbon Allowance
The Washington Carbon Allowance (WCA) is the tradable compliance unit in Washington State’s Cap-and-Invest Program, with each allowance equal to one metric ton of CO₂-equivalent. Allowances enter the market through state auctions and limited free allocations. Regulated entities — including refineries, fuel suppliers, utilities, and major industrial emitters — must obtain enough WCAs to cover their emissions. The index reflects the price of a WCA credit per day.
