Concerning emissions of greenhouse gases used for anesthetic purposes.

Washington's SB 5236 requires the Department of Ecology to study emissions from medical anesthetic gases like sevoflurane, desflurane, and nitrous oxide - potent greenhouse gases used in hospitals, dental offices, and veterinary practices - by July 2026. It mandates developing public guidance by April 2027, consulting health departments and medical groups, to help facilities reduce emissions without restricting clinical judgment for patient safety. Facilities must follow this guidance by January 2028, though the bill explicitly states no penalties will apply for non-compliance. The law focuses on voluntary adoption of best practices, referencing efforts in Scotland and medical associations, while ensuring medical professionals retain authority over patient care decisions.
