Northeast States Enact New Biodiesel Blending Requirements

Governors in Connecticut and Rhode Island signed legislation into law earlier this month that will require higher blends of biodiesel in home heating oil in the coming years. Consistent with previous changes to fuel specifications, the implementation dates fall on July 1 in each respective year.

  • On Monday, July 12, Connecticut Governor Ned Lamont signed HB6412, a bill to require B5 in 2022, B10 in 2025, B15 in 2030, B20 in 2034, and B50 in 2035. Details from CEMA can be found online here. Contact Chris Herb ( for more information.
  • On Tuesday, July 13, Rhode Island Governor Daniel McKee signed H5132A, which moves beyond the existing B5 requirement to B10 in 2023, B20 in 2025, and B50 in 2030. Contact Diane Quesnelle of EMARI ( for more information.

Also of note, the New York state legislature passed a bill (S3321A/A7290) in late May that expands the existing downstate B5 requirement statewide in 2022 and requires B10 in 2025 and B20 by 2030. Unlike the bills passed in Connecticut and Rhode Island, this legislation has not yet been enacted. It is currently pending Governor Cuomo’s signature. Contact Rocco Lacertosa of NYSEC ( for more information.

Heating oil volumes affected by legislation passed in these three states comprise around 40 percent of all gallons sold across the nine-state Northeast.
