MassDEP has proposed amendments to its greenhouse gas emissions reporting amendments at:

  • 310 CMR 7.71 to improve consistency with federal requirements, reflect the program's transition to a new electronic reporting platform, and remove requirements that are burdensome to facilities; and
  • 310 CMR 7.75 to add a reporting option for municipally-owned electricity sellers and clarify MassDEP authority to require certain reporting be directly to the Massachusetts Department of Energy Resources.
