Milton's greenhouse gas emissions grew 3.6% over five years, reaching 292,120 metric tons of CO2 equivalent in 2022, according to a town-commissioned inventory. That works out to about 10.2 metric tons per resident every year — a number that puts real weight behind a climate goal residents already said they want to hit.

Where the pollution is actually coming from.

The inventory puts a price tag on what's driving those numbers: transportation accounts for 52.8% of the town's total emissions, buildings for 45.4%, and waste just 1.8%. Those shares have barely budged since 2017, when transportation and buildings sat at 52.2% and 45.3% — meaning the same two sources have driven Milton's emissions for years, and any real progress will have to target cars and buildings directly.

A goal residents already backed, decisively.

Milton Town Meeting members gave this effort a strong mandate at the Fall 2025 Special Town Meeting, approving climate reduction goals with more than 92% support — targets calling for a 36% cut from 2017 levels by 2030, a 68% cut by 2040, and an 87% reduction by 2050, according to Sustainable Milton. That kind of near-unanimous support means this isn't a fringe priority — it's something the town has already told itself it wants to do.

The committee turning that mandate into a real plan.

The 11-member Climate Action Planning Committee, formed by the Select Board in 2023, is using the emissions inventory to shape a draft Climate Action Plan now posted for public review on the town's website. Its members include Dr. Alexander Hasha of Sustainable Milton, Arthur Doyle from the Conservation Commission, Maggie Oldfield representing the Planning Board, residents Anna Morgan-Barsamian, J. Hale Smith and Dr. Stephen Popkin, Kim Johnson as the Town Administrator's designee, and Sharese "Stevie" Caldwell representing the School Committee — with three seats still open, including one reserved for a Milton High School student.

Money already on the table.

Milton has already checked several boxes toward the state's Climate Leader Communities program, which offers grants up to $150,000 for decarbonization support and up to $1.15 million for larger accelerator projects. The town adopted the Specialized Stretch Energy Building Code in 2024 and has held Green Community status since 2010. Town Administrator Nick Milano has also approved the committee's application for state Planning Assistance Grants, according to the Milton Times, which help towns rezone for land conservation and regulate emissions through sustainable building.

A plan that admits it has to compete for attention.

The committee's draft plan is refreshingly honest about the tension it faces: zoning changes, school building maintenance, overcrowding, and budget stabilization all carry their own sustainability dimensions, and the committee says all of it needs to factor into the town's decisions together, not in isolation.

Want to be part of it?

The committee meets the third Thursday of each month at 6 p.m., open to the public with a Zoom option. Residents interested in joining can contact Dr. Hasha at [email protected]. The next meeting is Thursday, Aug. 20, at 6 p.m.
