This month, we celebrated 10 years of regional climate action through MAPC's Metro Mayors Coalition (MMC) and committed to goals for the next 10 years. Since 2015, the MMC's 17 cities and towns in our region have built an inter-governmental Climate Taskforce, adopted a regional "Net Zero by 2050" goal, implemented hundreds of policies and actions to reduce greenhouse gas emissions, and developed a first-of-its-kind regional heat preparedness and adaptation plan.


This newsletter also highlights an upcoming symposium on heat and health, the start of the 2025 Peak Demand Notification Program, grant opportunities, and more!

Celebrating 10 Years of Climate Work by the Metro Mayors Coalition


On Monday, May 12 the mayors and managers from the Metro Mayors Coalition (MMC) came together at the Museum of Science in Boston to celebrate the ten-year anniversary of the adoption of the 2015 MMC Climate Commitment, and the work accomplished to date. At the event, MMC members also signed an updated 2025 MMC Climate Commitment, recommitting to their shared goals of advancing regional climate efforts.

Fostering Collaborations: A Symposium to Advance Equitable Heat Health Actions

MAPC, in partnership with the Center for Climate and Health at Boston University School of Public Health (BUSPH), is hosting an in-person regional symposium titled Fostering Collaborations: A Symposium to Advance Equitable Heat Health Actions on Wednesday, June 18, 2025. By bringing together experts and leaders from academic, state and municipal governments, healthcare institutions, community-based organizations, foundations, and advocacy groups in the region, the symposium aims to help bridge the gap between research and practice. Learn more and view the agenda. The Symposium is part of Strengthening Pathways: a national conversation about health research.

MAPC 2025 Peak Demand Program

MAPC runs a free Peak Electricity Demand Notification program for our municipalities to learn how to reduce demand and the costs and emissions associated with capacity charges. MAPC can also help connect you to other demand management opportunities offered by ISO-New England (ISO-NE), National Grid, and Eversource.

Every morning from Tuesday, June 3 through mid-September, MAPC will send out an email that assesses the risk that the annual peak could occur that day and, if so, at what time. The notifications also include an outlook for the next week so municipalities can plan ahead. MAPC develops this assessment by analyzing data provided by the grid operator, ISO-NE.


  • Sign up for notifications.
  • Learn more about the ConnectedSolutions Active Demand Reduction initiative which provides utility payments for reducing energy usage during peak periods.
  • Join MAPC and Eversource on Monday, June 16 from 12-1 pm to learn more about the Peak Demand Notification Program and other ways to manage demand and costs this summer. Register now!

Solar Smart Permitting: SolarAPP+ Demo and Testimonial

Residential solar permitting in Massachusetts continues to be inefficient, adding delays and costs to solar installations that are passed onto customers and constraining the capacity of municipal officials. The U.S. Department of Energy's Solar Energy Technologies Office, National Renewable Energy Laboratory, and other stakeholders teamed up to develop Solar Automated Permitting Processing (SolarAPP+), a tool that makes it easier for municipalities to quickly and safely approve standardized rooftop solar projects. Available at no cost to cities and towns, SolarAPP+ has revolutionized permitting for typical residential solar installations: adopted by over 280 jurisdictions in 15 states, NREL estimates that SolarAPP+ saved municipal officials over 15,400 hours in staff time and accelerated solar permitting by 150,000 business days in 2023. SolarAPP+ works with jurisdictions to customize the platform for local requirements. The process requires no downloads and takes about two weeks to set up.


Interested in learning more—or becoming one of the first Massachusetts municipalities to adopt SolarAPP+? Join MAPC and partners on Thursday, June 26 at 11 am for an introduction to and demo of SolarAPP+ by Bronson Bast, the Community Engagement Lead from the SolarAPP+ Foundation. The webinar will also include insights from Kimberly Norman-Rosendam, the Chief Building Official for the Town of Guilford, CT. Guilford is an early adopter of SolarAPP+. 


Register for the June 26 webinar. Interested in SolarAPP+ but can't make the webinar? Email cleanenergy@mapc.org for more information.

Webinar Recording: E-Cargo Bikes: Small-Scale Deliveries for Big Impact

On Thursday, May 15, MAPC, in partnership with the City of Boston, Massachusetts Clean Energy Center (MassCEC) and NetZero Logistics, hosted an interactive webinar titled Small-Scale Deliveries for Big Impact.
