Ecology is considering amendments to Chapter 173-446 WAC to address new and revised cap and invest offset protocols. Offsets are projects or programs designed to reduce the amount of greenhouse gases (GHGs) in the atmosphere. In Washington’s cap-and-invest program, offset projects must also provide direct environmental benefits to our state. Offsets allow businesses to balance out the negative impacts of their emissions by funding a project that benefits the environment. The scope of this rulemaking will include consideration of updates to the US Forest protocol to increase the potential variety of offset projects that can be developed within the cap-and-invest program, as directed by RCW 70A.65.170(4)(b). This statute directs Ecology to conduct rulemaking that ensures that any updates or additions to the offset program are both based in the best available science, and support the needs of landowners and communities in Washington state. For this EJA, we are focusing specifically on the US Forest offset protocol rulemaking.
