HB2073– Reducing greenhouse gas emissions from anesthetics and studying alternatives for reducing those from a pesticide.
Prime Sponsor – Representative Slatter (D; 48th District; Bellevue) (Co-Sponsor Fitzgibbon, D)
Current status – Had a hearing in the House Committee on Environment & Energy January 11th. Replaced by a substitute postponing the designation of sulfuryl fluoride as a greenhouse gas and making some other changes that are summarized by staff at the beginning of it; passed out of committee January 23rd. Scheduled for a hearing in Appropriations at 10:30 AM on Thursday February 1st.
Next step would be – Action by the committee.

Summary
The bill would require the Department of Ecology to commission a study that analyzes the evidence supporting the treatment of sulfuryl fluoride (a fumigant pesticide) as a greenhouse gas. It would determine the potential sources of sulfuryl fluoride and of other gases with a high global warming potential that are used for anesthetic purposes in Washington, including Sevoflurane, desflurane, isoflurane, halothane, and nitrous oxide; and determine how they’re used in Washington and estimate the emissions from them. It would recommend potential points of regulation for each of them and measures for reducing or eliminating their emissions. The study would be due by July 1st, 2025.

Ecology would also be required to consult with a list of medical and environmental stakeholders in developing a guidance document intended to reduce the greenhouse gas emissions of anesthetic gases with a high global warming potential, without unduly limiting the judgment or needs of medical, dental, or veterinary professionals in providing safe and effective care. The Department would be required to consider:
(a) the efforts of other jurisdictions to restrict the use of such gases or otherwise reduce greenhouse gas emissions associated with the use of anesthesia;
(b) the guidance documents or best practices prepared by national and international anesthesiology professionals and guidance documents published in peer-reviewed medical journals; and,
(c) existing practices in place at facilities and by practitioners in Washington to limit greenhouse gas emissions associated with anesthesia use.
After July 1, 2026, facilities at which anesthetic gases were used, and the medical, dental, or veterinary practitioners that use such gases, would have to use anesthesia in a manner consistent with the guidance document.

Producers or suppliers of sulfuryl fluoride would be included in the Climate Commitment Act’s annual report if their greenhouse gas emissions exceeded 10,000 metric tons of CO2e. Ecology would also consult with the Department of Agriculture and stakeholders and report to the Legislature on the availability of alternative chemicals or practices that would be less hazardous to humans or the environment than the current uses of sulfuryl fluoride. By October 1st, Ecology would consult with the Department of Health and stakeholders, considering these studies, and recommend any further statutory changes needed to appropriately and effectively reduce these emissions.
