Climate Commitment Act
History
History
The Climate Commitment Act stands as a remarkable example of effective state-level policy aimed at mitigating climate pollution and fostering a fair and sustainable future.
Back in 2021, Washington State took a pioneering step by passing the Climate Commitment Act (CCA), a groundbreaking cap-and-invest legislation. This forward-looking law places a gradual limit on climate-warming emissions and allocates resources to implement solutions that promote equity, prosperity, and resilience across the state. Working hand-in-hand with other robust state policies, the CCA is projected to achieve an impressive 95% reduction in emissions by 2050. Moreover, it fosters stronger consultations with tribal nations, enhances air quality and environmental justice, bolsters climate-focused initiatives, and bolsters the state’s economy.
The journey toward passing the CCA holds valuable insights that can be adapted by other states seeking to address climate change. Prior to this achievement, numerous attempts to implement carbon pricing had faltered over the course of more than a decade. However, the CCA triumphed with the collective backing of a diverse coalition of stakeholders, representing a broad spectrum of interests within the state. This inclusive collaboration ensured that the law not only met science-based emission reduction targets but also brought about positive co-benefits for Washington’s environment, businesses, and marginalized communities.

Could it work as well on the climate crisis?
California was the first state to put Cap-and-Trade to work on greenhouse gas (GHG) reduction. Results there show targets achieved ahead of schedule, with a healthy economy.
Now, just as we in Washington state followed California’s lead but improved upon their program, we anticipate other states will follow our lead. Already, the state of New York is beginning the process of implementing a similar Cap-and-Invest system. California is considering improvements to their system by referencing Washington’s CCA.
