Washington State House Bill 1050 - 2021-22
Washington builds on earlier state legislation and the AIM Act in an effort to reduce greenhouse gas emissions.
Washington's Department of Ecology (Ecology) adopted into law two sets of rules—Chapters 173-443 WAC, Hydrofluorocarbons (HFCs) and other Fluorinated Greenhouse Gases and 173-445 WAC, Air Quality Fee Rule—which went into effect on January 31, 2024.
The information below is to provide awareness of these regulations, and we recommend you work with your internal regulatory teams to ensure you have the right plan for your organization.
