Chapter 173-446 WAC – Cap-and-Invest Offsets
We propose to update Chapter 173-446 WAC, Climate Commitment Act Program Rule. This rulemaking may consider amendments to address new and revised Cap-and-Invest offset protocols, including WAC 173-446-505 and WAC 173-446-580.
Offsets are projects or programs designed to reduce the amount of greenhouse gases in the atmosphere. In the Cap-and-Invest Program, offset projects must also provide direct environmental benefits to Washington state. Offsets allow businesses to balance out the negative impacts of their emissions by funding a project that benefits the environment, such as capturing methane on dairy farms or planting trees in urban areas.
This proposed rulemaking updates the ozone depleting substances (ODS) protocol and will increase technical standards, decrease obstacles to project development, and reflect policy advances. Ecology has entered the second phase of this rulemaking which opens the formal public comment period.
