Cambridge committee reviews draft Net‑Zero Transportation Plan and outlines near‑term priorities

At a virtual meeting of the Cambridge City Council Health and Environment Committee, members and staff reviewed the draft Cambridge Net Zero Transportation Plan (NZTP) and discussed next steps for finalizing the report and beginning implementation.

The plan, presented by Stephanie Groll, director of transportation planning in the Community Development Department, lays out a mix of strategies intended to cut transportation-related greenhouse gas emissions by shifting trips to walking, biking, micro‑mobility and transit, and by electrifying the remaining car and truck trips. “This plan will be critical to creating measurable and accountable goals so that we have the ability to track our progress over time and make changes and adjust if necessary,” Councillor Nolan said at the hearing.

Staff told the committee that technical modeling and current programs already in motion account for roughly 68% of the reductions needed to reach net‑zero in the transportation sector; the plan focuses on the additional measures required to close the remaining gap. Groll said the plan used national best practices, local greenhouse‑gas inventories and more than 50 structured community conversations to shape recommendations.

Community feedback, staff said, coalesced around two themes: people do not want to be “punished” for owning a car, and they want more and better options to avoid driving. “Don’t punish me for owning and using a car; make it easier for me not to,” staff summarized from the outreach. Public commenter Ethan Frank urged the city to prioritize reliable transit, saying, “The only proven way of reducing traffic is by giving people alternatives to driving with reliable public transit.”

Recommended strategies are grouped in six categories: community engagement; bus and shuttle improvements (including bus priority treatments such as signal priority, queue jumps and lanes); walking, biking and micro‑mobility investments; measures to reduce car trips and ownership; expansion of publicly accessible electric vehicle (EV) charging (including charging for e‑bikes); and targeted programs to support equity and accessibility. Staff identified four near‑term priorities for the next one to two years: intensified outreach to help residents navigate options and discounts, bus priority projects on key routes, improved bike access and Bluebikes expansion, and increased publicly accessible EV charging and fast charging infrastructure.

Staff also detailed programs and existing tools that will support the plan. Examples discussed included the PTDM (parking and transportation demand management) requirements negotiated through special permits for new development, the Electrify Cambridge program (which offers an approximately $1,500 rebate for household EV charger installation), partnerships with Bluebikes and efforts to coordinate shuttle and private‑operator data into common transit feeds so riders can find services in mapping apps. Groll and Suzanne Rasmussen, director of climate initiatives for the Office of Sustainability, said the final report will include more technical detail and assumptions and will be published in May 2025; the plan is intended to be updated every five years.

Committee members pressed staff for detail on several operational items. Councillors asked for the breakdown of the items that comprise the 68% projection, recent trends in EV registration (staff noted EVs rose from about 1% of registered passenger vehicles five years ago to about 4% in the city’s RMV data), and documentation on how frequently developers have provided EV‑ready parking through the special permit process. The committee also discussed resident parking permit rules (a recent limit of four permits per person was enacted; staff said the city will collect and provide data on permit distribution) and accessibility issues around installing curbside charging across sidewalks.

Members and staff discussed regional coordination. Staff described ongoing coordination with neighboring municipalities and MBTA partners, noted the city’s interest in participating in regional conversations about congestion pricing, and said the plan recognizes many implementation factors (fuel and tax incentives, MBTA finances, regional infrastructure) are outside Cambridge’s sole control.

The committee discussed next steps for the plan: incorporate committee and advisory‑group feedback, finalize a technical appendix with assumptions and emissions calculations, publish the final report in May 2025, and move to implement the four near‑term priorities over the following 1–2 years. The city will also continue advisory‑group review and community outreach before the final plan is adopted by the council.

The meeting closed with a roll‑call motion to adjourn, which passed 4–0.
