The bill S.171, introduced by Senator White, aims to establish a Clean Fuels Program in Vermont by directing the Commissioner of Environmental Conservation to adopt rules that set low carbon fuel standards for gasoline, diesel, and alternative fuels. The proposed legislation includes a new chapter, Chapter 43, which defines key terms such as "greenhouse gas" and "low carbon fuel standards." The Commissioner is tasked with creating a phased implementation schedule to reduce greenhouse gas emissions from fuels by 10% below 2018 levels by 2030, while also considering the standards of other states. The bill outlines various provisions, including exemptions for small fuel importers and specific standards for biodiesel fuels.

Additionally, the bill mandates a public engagement process before rulemaking, requiring at least six public meetings across diverse counties to gather input on the Clean Fuels Program. The Commissioner is also required to submit interim reports to the General Assembly by specified dates and to file final proposed rules by January 15, 2029. The act is set to take effect on July 1, 2026.
