In April 2026, Mayor Michelle Wu released Boston's 2030 Climate Action Plan — the city's roadmap for cutting carbon emissions and preparing neighborhoods for a changing climate.
It's the successor to the 2019 plan, but with a different character: where past plans focused mostly on what City government itself would do, this one is built as an all-of-city effort, meant to coordinate action across City departments, institutions, businesses, and residents alike.
- Mitigation: Slashing greenhouse gas emissions (50% reduction by 2030, full carbon neutrality by 2050).
- Resilience: Adapting local infrastructure to handle extreme weather, coastal flooding, and urban heat island impacts.

Cut citywide carbon emissions by 50% by 2030 on the path to total carbon neutrality by 2050.

Focus areas include building retrofits, clean grid transition, and bike infrastructure (like Bluebikes and electric bus fleets).

Lowering household energy bills through Community Choice Electricity, expanding urban tree canopies to reduce summer heat islands, and creating green job pipelines (such as PowerCorps Boston).

Cut community-wide greenhouse gas emissions 50% by 2030 and reach carbon neutrality by 2050
Protect 10,000 residents from coastal flood pathways by 2030
Add 300 acres of "greened" land (parks, permeable surfaces, rain gardens) to absorb stormwater
Cut municipal (City government) emissions 60% by 2030, 100% by 2050
Reduce heat-related emergency room visits by 25%
Bring tree canopy coverage up in the neighborhoods that currently have the least — some are below 20%, compared to a citywide average of 27.2%

Home energy Programs like Boston Energy Saver help weatherize and electrify homes (insulation, heat pumps) — directly supporting the buildings-sector target and cutting utility bills in the process.

Trees and green space Requesting a street tree, supporting local greening projects, or simply not removing yard trees supports both the heat-reduction and stormwater targets — tree canopy does double duty, cooling neighborhoods and absorbing rain.

The plan's climate justice language isn't just framing — it reflects a real, decades-old pattern in Boston. Neighborhoods like Roxbury, Chelsea, Chinatown and East Boston carry disproportionate environmental burdens: Roxbury's childhood asthma hospitalization rate runs roughly six times the state average, largely a legacy of highway construction, diesel bus depots, and industrial siting decisions made without those residents at the table.
These are also, not coincidentally, neighborhoods with lower tree canopy and higher heat exposure today. This is the history the City's Climate Justice Framework is responding to, and it's why the plan directs resources toward "environmental justice communities" first rather than distributing them evenly citywide.
Much of that history — and the pressure that produced today's policies — came not from City Hall but from resident-led organizing. Check out the Community & Culture section for more information on the organizations that are doing this important work in Boston.
Boston’s Office of Climate Resilience works directly on the frontlines to protect our neighborhoods from the physical impacts of climate change: rising sea levels, severe stormwater flooding, and dangerous urban heat waves. Through major initiatives like Climate Ready Boston, the office designs nature-based coastal defenses, expands urban tree canopies to cool hot pavement, and equips residents with neighborhood preparedness tools.
