STIP GHG Appendices
MassDOT and the Commonwealth’s Metropolitan Planning Organizations (MPOs) have been assessing and publishing Transportation Improvement Plans’/State Transportation Improvement Programs’ (TIP/STIP) greenhouse gas (GHG) impacts since the 2013-2016 STIP process in an effort to better understand how project programming and funding decisions increase or decrease transportation sector GHG emissions. A STIP appendix reports these impacts each year.
