Date: 2021

On 17 May 2021, Washington Governor [Jay Inslee](/people/env-jay-inslee) signed the Climate Commitment Act, establishing an economy-wide cap-and-invest program that sets a declining limit on greenhouse-gas emissions and requires major polluters to buy allowances. The program launched in 2023, and in November 2024 Washington voters rejected Initiative 2117, which sought to repeal it, leaving the law intact.
