Washington’s New Cap-and-Trade Program: A Costly and Badly Flawed Climate Mandate

New program is 3x more costly than predicted

Washington’s newest climate mandate is the most expensive Cap-and-Trade program of its kind in the nation. The cost to comply with this program is estimated to be $1.3 Billion in the first year alone.1 This is 3 times more expensive than originally predicted when the program was passed by the legislature.2

Many experts are highly skeptical about the long-term feasibility of this program. In Washington’s rush to become the “greenest” state in the nation, the program doesn’t consider whether there is even a realistic way to comply with the aggressive goals that have been set by the program or what the cost impacts will be for Washington’s economy and consumers.3
