The purpose of this report is to assess Boston’s progress toward achieving net-zero emissions and becoming resilient to future climate disruptions in an equitable manner. It has been six years since the publication of the Boston Research Advisory Group Report on Climate Change and Sea Level Rise Projections for Boston and four years since the publication of Carbon Free Boston. While the main findings from Boston’s reports remain relevant, our understanding of resilience needs and mitigation strategies has become much clearer. Thus, our assessment of progress asks: How well is Boston—as a civic community—driving forward system transformations to meet climate, resilience, and equity goals?Explore the Section
The next section of the report looks more closely at our collective progress toward commonly-accepted goals necessary to rise to the challenge of climate change. These goals include Boston's expressed goal to bring greenhouse gas emissions to net zero by 2050, to enhance resilience significantly, especially for communities of color that have had disproportionate exposure to environmental harm and economic disinvestment, and to ensure that environmental justice is prioritized in allocating the benefits of climate action initiatives. While city government can play a key role in advancing on these goals, it cannot do it alone. State and federal policy, the private sector, and even individual actions can all have critical impact on Boston's progress.Explore the Section
To eliminate emissions, build durable resilience, and achieve climate justice, we must transform a broad set of deeply ingrained energy, infrastructure, and human systems. To that end, the report highlights 12 outcomes that are considered necessary to make progress toward the climate goals. Many of the outcomes touch on two or all three goals. The intention in this section is to advance the conversation by expanding understanding of each outcome and where we stand, rather than to grade any single entity on progress.

Boston must generate and be supplied with electricity sourced from renewable and other low-carbon generation resources.
Phase out the use of non–zero emissions vehicles and deploy accessible charging infrastructure.
Build more housing near transit and within the urban core. Accelerate strategies to reduce vehicle reliance and ownership by growing alternative travel modes and reshaping the street to prioritize the needs of people over vehicles.
Electrify buildings while updating them for energy efficiency, comfort, and resilience.
The utility-owned electric distribution grid must be modernized to support electrification, share the solar power generated on its roofs, and ensure resilience. Simultaneously, developing and sharing alternative thermal energy resources—such as the earth, water bodies, and waste heat—can efficiently displace fossil-fuel heating.
Fossil fuel use must drastically decline by 2050; however, modest judicious use of fossil or alternative fuels (e.g., bioenergy) will be needed to support low-cost reliability and resilience.
The amount of waste produced needs to decline even as we shift to more sustainable waste treatment practices. These practices include locally-sited material and energy recovery processes such as composting and technologies that convert organic waste to gas, electricity, or liquid fuels.
Appropriately support the scaling of carbon dioxide removal (CDR) technologies to extract carbon from the atmosphere and permanently store it in geologic or natural stocks.
Boston must better manage its trees and natural spaces to ensure they grow and provide enhanced benefits to their communities in a changing climate.
Maintain ongoing implementation of coastal resilience strategies across Boston’s and the region’s coastline to reduce the risk of coastal and riverine flooding, with the aim of protecting all neighborhoods.
Prepare the infrastructure systems that support life in Boston for future climate conditions and create new resilient systems. These include stormwater, energy, transportation, and emergency support systems in both public and private spaces.
Act with an acknowledgment that frontline communities have experienced a history of discriminatory practices, neglect, and outright damage.
Our collective response to climate change will require more than just discrete or incremental projects. The report highlights four "big lifts," multidecade, multi-platform projects that would play critical roles in helping the city align with its climate and equity goals. These projects are not the only paths, but they represent the kind of well-funded, coordinated public and private sector partnerships that can make significant impact in our energy consumption and efficiency, our climate resiliency and the equitable protection of all people in the city and region from climate-related challenges.

70,000 single- and small multifamily homes need to electrified by a new industry, powered by a workforce that represents the communities it serves.
Energy planning must be rapidly modernized to meet the increasingly local needs of the energy transition and the communities that host energy infrastructure.
Boston needs to be part of the decision-making process and creation of a governance structure for managing the Massachusetts coastline.
Boston must run with its “Green New Deal” vision to integrate climate action with reparative planning (and become a national leader in the process).
