Acknowledgment & Dedication This report is dedicated to the hundreds of Cambridge residents who have worked over the years to push Cambridge to address the climate crisis in a meaningful way. From convening climate congresses and plenaries and seminars to volunteering hundreds of hours engaging in thoughtful comprehensive educational efforts to strong and forceful advocacy, these residents have consistently worked to make the city a leader. Some people have been writing and speaking for decades, others for far shorter. All share a passion for change, a conviction that Cambridge must stand up and be a role model, and a deep- seated and growing concern about the implication for our city (and the world) of our lack of progress in reducing emissions and mitigating the impact of the already changed and changing climate. The crisis is with us; it is accelerating. The CCWG seeks to accelerate Cambridge’s effectiveness in climate action and become a leader in impact, not only intent. The CCWG honors all the work that has been done and the people who demand greater urgency and bold action. 1

Introduction The Climate Crisis Working Group was convened by Mayor Sumbul Siddiqui with Councillor Patty Nolan to build on the city’s work on climate. The main goal of the group is to increase the urgency of our climate actions and the impact of that work by providing guidance on how Cambridge can better address the climate crisis. The need for greater urgency was made exceedingly clear by the recent Net Zero Action Plan 5-year Impact Evaluation Report, released in December of 2020, which concluded that the City will have to accelerate emissions reductions twentyfold over the next ten years in order to meet our goals. That sobering assessment means immediate action is needed. Despite more than twenty years of climate efforts, with multiple worthy initiatives, citywide greenhouse gas emissions have remained relatively unchanged since 2003. Though some of this can be accounted for in Cambridge’s growth, other entities with similar expansion have had some success in reducing emissions. It was time to take stock and see if a group of relative outsiders - most of whom had not been directly involved in city climate efforts - could come up with some useful ideas. Our goal was to provide input and guidance to the City Council and the administration by reviewing climate work within the city, building on existing efforts, consulting with community advocates, and soliciting input from the group members. The working group sought to identify ways to accelerate progress and develop a list of targeted actions for the City to implement. From the beginning, the goal was to make sure the output of the group was not a report to put on a shelf, but a guide for a new approach to climate work. The city has enough reports and lists of actions to take. We need a culture shift, and financial investment to match the need. We see the value added of the CCWG to the stellar climate work done over the last two decades is our willingness to call out and identify lapses in program implementation, effectiveness and the general lack of progress. In response a key recommendation is to propose a culture shift. The CCWG met six times during the fall of 2021, all remotely due to the COVID-19 pandemic. Find short meeting summaries below, with full meeting slides available in the appendix. Meeting 1 - September 1, 2021 The first meeting started with a welcome message and an introduction of the members. Meeting discussion covered: an overview of the CCWG’s goals, a quick review of the City’s previous climate actions, successes, and failures, and a discussion of future meetings and next steps. 2

Meeting 2 - September 15, 2021 The meeting began with a review of the CCWG work plan and discussion of any necessary edits. Then, the rest of the meeting was devoted to identifying key actors in Cambridge’s climate goals, actions they may take, and discussion ended up centered on the concept of focusing on potential barriers to carrying out climate actions. Meeting 3 - October 13, 2021 During this meeting, the CCWG reviewed the City’s past and current climate actions, focusing on where they succeeded or failed to meet the goals. The CCWG then reviewed why certain initiatives succeeded or failed, which barriers they faced, and brainstormed ideas to overcome these barriers. Meeting 4 - October 27, 2021 At this meeting, the discussion started with a review of the recently released Net Zero Action Plan 5-Year Report, then summarized the CCWG’s top ideas to date. The group discussed and narrowed down feasible goals to 3-5 ideas, then broke into smaller groups to create action plans for these ideas. Meeting 5 - November 17, 2021 At the beginning of this meeting, the Group reviewed the goals that had been established at Meeting 4, then reviewed the Building Energy Use and Disclosure Ordinance (BEUDO) draft amendments (with presentations by city staff and CCWG members) and discussed reactions. The meeting concluded with compiling a list of smaller, simpler action items to complement the main goals. Meeting 6 - November 30, 2021 The last meeting was largely devoted to discussing and refining some recommendations with acknowledgement that the work was not done, but that the conceptual framework of barriers and focus on ensuring impact was helpful. There was some discussion of the final product and next steps. 3

Cambridge Climate History & Next Steps Cambridge declared a climate emergency over a decade ago and has been actively working to address the climate crisis for more than twenty years. The city has taken some important steps, yet is behind on overall climate goals and has consistently missed the mark on both citywide goals and deadlines. CCWG group members, all of whom have a strong awareness and understanding of the climate crisis, believe Cambridge can and should be a leader on climate action and climate justice. And the city is not living up to its potential. Over the course of six meetings, the CCWG covered a lot of ground and wrestled with the question of how to make the extensive climate work in the city more effective. The starting point and inspiration for the CCWG was a sense that the city is underperforming in terms of its climate goals, but has the potential to be a climate leader. Reviewing the data on citywide climate goals, projects, and plans leads to the conclusion that despite a lot of good work, Cambridge is not doing enough and is not working effectively or smartly. To date, the city’s impact on the reduction of citywide emissions has not been sufficient; therefore, a critical review of the overall body of work is warranted, with an attempt to understand the necessary change for greater effectiveness. Our goal was to review the major areas for potential impact, seek to affect the sense of urgency, and produce recommendations for the City. During the course of our work, three questions guided our thinking: What are the city’s greatest successes and what facilitated them? Where is there a lack of progress or unmet goals and how can our understanding of certain barriers help re-shape the city’s actions, policies, priorities, and culture? What can the city do to make more progress? The CCWG was formed and members agreed to serve because of a shared belief that the city’s efforts have not been effective enough. The city administration has many sound plans and has committed substantial talent and resources to them. However, we are still falling behind our targets and failing to reach our goals. Our central question asks why, and is there some way to address that shortcoming - or is it inevitable given the scope and scale of the challenge? In some areas Cambridge has been a leader and used as a model by other cities and towns. In other areas other cities and towns are ahead of Cambridge and can serve as a model for our future actions. The consensus of the group is that in order to make progress - and for the CCWG to deliver on the promise of positive impactful disruption - it is 5

critical to avoid the trap of collecting ideas and creating yet another plan that, although solidly full of good ideas and intentions, still does not move the needle. Cambridge has many reports and plans related to climate action including many with specific action steps and deadlines. Based on our discussions and work, the recommendations come at two levels. First, an overarching primary recommendation is to address barriers to success. These barriers are: the cultural mindset around climate, lack of funding, an aversion to mandates, and structural challenges. The second level of recommendations are specific recommendations for actions to take, many of which are already underway in the city. The seven identified recommended action areas build on existing work and urge more decisive action, with accelerated timelines. To sum up the approach that needs to be taken: Cambridge - all parts of the city and the community - needs to act as though the climate crisis is the emergency the city declared a decade ago. The COVID-19 response showed that rapid change can happen when facing an emergency, and the city’s recent response to the affordable housing situation also provides a model: direct funding for affordable housing doubled to over $30 million in the last two years and almost tripled over the last decade. It is in keeping with these models of how to act in the face of an emergency that we present these recommendations to the City Council. Without addressing the barriers that have stymied effective action, progress will continue to be slower than what is possible and desired. That means working to change a mindset that has contributed to slower progress than is possible and desired, use mandates - along with stronger incentives - to achieve results, and fund climate efforts commensurate with the need. The recommended actions to be taken are feasible, although some will engender pushback (especially in terms of timelines and breadth). The City - both the City Council and the administration - will have to stand firm if Cambridge’s climate leadership is to be asserted. 6

Identifying & Addressing Barriers to Success The original goal of the CCWG was to be bold and disruptive in coming up with an action plan which could lead to impact on the city’s multifaceted and deep work on climate issues. It was clear from the first meeting that many climate actions and steps were already underway, being discussed, studied, proposed and/or prioritized by several groups. For the last twenty years. So why hasn’t there been more progress? Of course there are many reasons that are real: the issue is daunting, the challenge great and moving the needle on reducing emissions and changing the trajectory of climate disaster is monumentally difficult. However, there are signals and some evidence that more progress could have been made - based on the experience of some players, notably the city itself in its operations and two major institutions in the city - Harvard and MIT. All three of those entities have reduced emissions and made more progress towards meeting climate goals than the city as a whole. There is something the CCWG identified that could help: our value added from our work is a recommendation to put as much focus on WHY things haven’t panned out - as on identifying and prioritizing actions to take. That approach of directly addressing the roadblocks and barriers - in order to understand and remove, not to dwell on them - has not been as central to climate work as we think it should be. The CCWG kept coming up against the need to identify and directly address barriers if the city is to successfully meet the climate crisis challenge. There are structural barriers that limit ability to make changes - many of which can only be resolved at the state or even federal level. The CCWG acknowledges those and encourages the City administration and City Council to push for changes whenever possible to address the structural barriers at those levels. In addition to recognizing the importance of addressing structural barriers, the CCWG identified three other sets of barriers that collectively inhibit effective climate action. At the heart of the discussions were two themes: Cambridge needs tangible results with a focus on environmental justice, since the climate crisis in all its manifestations most adversely impacts vulnerable populations. And a key to success over the next few years is to consciously and intentionally address the barriers the City can affect directly: Mindset, Mandates and Money. 7

Mindset: A culture change is needed. ◊ The acknowledgement of failures is as important as the celebration of successes. • Too often, failure to meet goals is not acknowledged, leading to continuation of a status quo which hasn’t worked. • Not communicating lapses leads people to not knowing that change is needed and thus less urgency to adjust actions. ◊ Accountability and oversight are needed. And full transparency. • Timelines - the City must create a mechanism to monitor deadlines since climate deadlines have been consistently missed. Adjusting goals is sometimes necessary, yet deadlines should not be ignored. And when a goalpost is adjusted, it should be public, which builds trust. • Implementation - there should be a way to measure if implementation occurred as planned, so we can celebrate the climate successes and adjust when off course. • Results/outcomes measuring - there should be a centralized system to monitor and measure results of climate initiatives in more depth than the Sustainability Dashboard, which has few goals and outdated results. Limitations in data access and measuring outcomes should be fixed. Responsibility for results must be clear. Outcomes must be consistently reviewed and updated. • Openness - A lack of transparency has hindered progress and participation. ◊ Inclusive open process of gathering and using input from all stakeholders must become standard - required. • The Climate Protection Action Committee (CPAC) has been underutilized, left out of key discussions and has no authority to effectively oversee the areas it is charged with overseeing. • Engage and use community experts - respecting, listening to, and following advice from a larger group will improve outcomes. • The authority of certain groups, like the Net Zero Action Plan Task Force (NZAPTF), activists, and residents should be better defined ◊ Evaluation of program design and effectiveness needs to be clear, timely, open and honest. Many programs have been started and time spent on climate initiatives which then fade away with not even a report that can inform future work [Example: the Georgetown Climate Prize effort.] 8

Mandates: Carrots need to be bigger and more flavorful AND used with sticks to get the desired results. ◊ BEUDO is a prime example of how there was not much incentive to change behavior, or direct support in the form of funding or recognition. And exposure of emissions wasn’t sufficient - and climate leaders were not recognized. Now requirements are needed and should be enforced through rules and regulations along with strong incentives. Effort went into the collection of data and time spent by the city and property owners to report, with BEUDO itself having little impact on reducing emissions - those property owners working on reduction were already engaged. [See below for update to BEUDO.] ◊ Examples of necessary mandates include: • Transition point electrification: This could be a game-changer and should be developed as soon as possible. • EV use and charging, bicycle, and public transit infrastructure should be required more widely. Money: Investment needs to match the challenge. ◊ Major investmentment is needed to make the city an environmental leader ◊ Ideas with potential for meaningful impact: • Fund and leverage Eversource programs to create a GeoGrid demonstration in Cambridge. Cambridge should explore how to be a pilot site by partnering with Eversource or outside funders. Perhaps use a third-party installer who funds the project and owns the infrastructure. HEET is hosting a meeting with interested municipalities in April or May to allow them to consider both options. Invest in a Virtual Power Purchase Agreement (VPPA, as MIT did in 2016). • Use PACE or another mechanism to enable financing for heat pumps and/or solar panels for residents, especially low income residents. If city funding mechanisms cannot be used, pursuing outside funding should be a priority. • Invest in EV, bicycle, and public transit infrastructure and incentives across city operations and for all residents, visitors and employees. 9

Recommendations Below are seven recommendations - which are appropriate areas of focus for and action by the city in the near term. These actions are mostly items drawn from the work of other city climate groups, notably CPAC and the offshoots of NZAP and CRZTF and Mothers Out Front, Green Cambridge and 350MA Cambridge. Some actions were identified through the CCWG and have not been part of the CPAC work - although the city has worked on some items outside of CPAC and other climate groups. There are many other ideas, actions, and initiatives identified by CCWG members as worthy of effort and pursuing which could be included in future climate work. The CCWG could not cover them all in the short amount of time. There may be some possibility for group members to continue the work in some form. It is important to note, though, without the changes in mindset, mandates and money summarized above, these actions are not likely to yield the desired impact. 1. BEUDO Amendments Performance Requirements: strengthen, implement: In the City of Cambridge, energy use in buildings accounts for the majority of greenhouse gas emissions -- about 80%, compared to most cities where buildings represent about half of emissions and less than half nationally and globally. In response to growing concerns about energy use and climate change, the Building Energy Use Disclosure Ordinance (BEUDO) was enacted by the Cambridge City Council on July 28, 2014. This ordinance requires owners of larger buildings to monitor and report annual building energy use to the City. This data is then categorized and made available on the Cambridge Open Portal. The intention of this ordinance was to make energy and water use data publicly available, so that various users such as potential property buyers, tenants, realtors, and others can make informed decisions, hopefully incentivizing building owners to reduce energy usage in their building stock. However, it is now clear that energy use disclosure is not enough, and ordinance amendments1 to introduce performance requirements are currently under consideration by the City Council as contemplated in the original ordinance. The proposed ordinance amendments require not only disclosure of building energy use, but establish a schedule 10 1 See appendix for ordinance amendment text

for reductions in GHG emissions. As written the CCWG believes the draft recommendations fall short of the actions necessary to meet the challenges of the climate crisis. Currently, the amendments require each BEUDO property to comply with Greenhouse Gas Emissions requirements over a course of 6 compliance periods, resulting in net zero emissions in 2050. The CCWG recommends that this timeline be accelerated, with net zero reached by 2040 at the latest. And that all new buildings within the scope of BEUDO be required to be net zero immediately. This goal is in line with a policy order passed by the City Council in 2017, calling for 100% clean and renewable energy in the building and transportation sectors by 2035. Additionally, the amendments should be changed to add a requirement that outliers which use significantly more energy than other buildings must reach a certain baseline within the first few years. In other words, there should be a threshold that all BEUDO covered buildings must meet by 2025, then start their emissions reductions plans from there. This would ensure that buildings which already meet the threshold are not exempt from reducing emissions -- they will still stick to the emissions requirements under the compliance period schedule -- but large emitters will need to catch up to them. RECOMMENDATION: Amend BEUDO along the lines of the city proposal, with stronger elements: Shorten the timeline for net zero, ensure the highest alternative payment is required, bring outliers’ emissions down faster. 11

2. CCE Changes: higher RPS for the standard offering, including community shared solar: The Cambridge Community Electricity Program (CCE) is an electricity aggregation program authorized under MGL XXII, Ch. 164, §164 that opts-in residents to electricity supply selected by the City via City procurement process. CCE provides consumers with two options:, Standard Green and 100% Green Plus. Residents and businesses on Basic Rate are automatically enrolled in Standard Green, which meets the minimum Massachusetts renewable energy requirements, including 20% from “premium” renewable energy sources in New England (MA Class I RECs). In contrast, 100% Green Plus offers 100% of electricity from “premium” renewable energy sources in New England (MA Class I RECs), while also purchasing MA Class I RECs to achieve 100% renewable energy. Customers can also choose not to participate in the CCE program and opt down to Eversource basic service or dozens of other suppliers. Cambridge CCE participation rates show that most people stay in the default program option - Standard Green. Very few people opt out of the supply selected under CCE by the City. One issue is that for all new accounts, it takes a while for the account to be part of CCE. Only about 5% opt up to 100% Green Plus. Given inertia and the fact that it takes action, no matter how easy, that low percent is not surprising. However, since Cambridge perceives itself as a climate leader and enormous effort went into trying to get people to opt into 100% Green Plus, this program is an example of a communication and action strategy that did not achieve the desired result. The communications efforts on this have yet to be evaluated and assessed, which might help guide future efforts in other areas. Other cities and towns have different program offerings; conversations with representatives from the cities of Somerville, Natick, Newton and Boston have documented that most customers stay in the default option, while a small number opt up or down. The difference, though, is that Cambridge’s default option has a low percentage of renewable energy compared to other municipalities (see Fig. 1, Fig. 2 in Appendix B). The city touts that the number opting in to 100% renewable option has doubled, but with only 5% participating, the city’s use is not significant enough to be making as much difference as other municipalities with a much higher RPS. Cambridge’s current standard offering is the minimum percent renewable energy required by law. While there is an addition of 0.2¢ (2/10 of a cent) that goes to onsite renewable energy in Cambridge, this adder generates relatively little funds - about $650K/ year. RECs in New England are priced at the point where they make a difference to the greening of the grid - 12

which is the point of RECs. Collectively the community aggregation programs in municipalities across Massachusetts are affecting the addition of renewables onto the grid. Cambridge can and should do more to contribute to that effort. In fact, Cambridge’s first CCE plan was described as greenwashing in a report published by the Green Energy Consumer Alliance review in 2020 of community electric aggregation in Mass[ page 19]: The CCWG recommends that the CCE program amend the default program option and follow the lead of other cities and have three tiers. A standard offering (“Standard Green”) which is the default with a much higher RPS than the minimum, a basic offering meeting the minimum Massachusetts renewable requirement, and a 100% renewable offering. The Standard Green should at least match surrounding municipalities. Standard (default) offers for other cities as of summer of 2021 are as follows: ● Lexington - 100% renewable ● Newton - 80% renewable ● Watertown - 53% renewable ● Worcester - 38% renewable ● Natick - 31% renewable ● Boston - 28% renewable ● Somerville - 28% renewable ● Cambridge - 18% renewable = state minimum required In addition to being able to opt-in residents to City-selected electricity supply, state rules governing CCE also allow the City to opt-in residents to Community Shared Solar (CSS) under the Solar Massachusetts Renewable Target (“SMART”) program. The CSS program delivers electricity to the grid from solar farms across Massachusetts creating new sources of clean electricity and supporting development of the solar industry in Massachusetts. CSS reduces electricity costs and the SMART program makes additional savings available to low income households. LICSS is currently operating and details are being worked out with DPU on including in aggregation programs. It is expected that soon the City can opt-in low income households without any outlays on the part of the City or residents, no use of space within the City, no use of City land, and no installation on the property of the City or its residents. City of Boston is working with DOER and DPU to use its CCE program to enroll 20,000 low income households in Boston in CSS. CCWG recommends that City of Cambridge join with City of Boston working with DOER and DPU to take advantage of this opportunity provided to municipalities under state law (M.G.L Title XXII Ch. 164 §134). RECOMMENDATIONS: 1) For Cambridge to be a climate leader, we must offer a higher percentage of MA Class I RECs in our Standard Green option. The CDD should either increase the default (standard) RPS to 80% renewable or copy Lexington’s 13

model of a standard offer at 100% renewables not in New England which is very close to Cambridge’s 18% renewable price, and an opt-up option of 100% Renewables in New England. 2) Follow Boston’s example by using CCE to opt-in low income households to develop new clean energy sources and simultaneously reduce energy burden for low income households without outlay on the part of the City. 14

3. Solar: City should invest in a VPPA, expand community solar: The Cambridge Community Development Department is currently exploring the possibility of signing a Virtual Power Purchase Agreement (VPPA) as a way to off-set the city’s emissions. With a VPPA, Cambridge would invest in a distant, off-side solar installation that reduces carbon emissions by displacing dirty energy in the host region, and may result in a positive economic return to its owners/ financers from the sale of electricity. MIT and many other institutions have done VPPAs - even if a VPPA is just one step towards 100% renewable energy, it is a proven way to move the needle and contribute to a greener grid. The CCWG enthusiastically supports this idea. The CCWG notes that on-site solar generation for all city properties - residential and commercial - is an important way every resident can be part of the solution. The CEA has been working to make headway in getting 1-4 family homes to install solar, and a report on the CEA’s effectiveness is underway and could be valuable in determining how to ramp up those efforts. The installation of solar is challenging, and those homes collectively generate less 15% of citywide emissions. However, with the need for electrical capacity and the inevitable huge increase in demand for electricity, every possible clean-energy addition to the grid, including small- scale onsite solar should be pursued. And, it is a solid way for those residents to contribute to solutions. Cambridge should support the development of clean energy and reduce energy burden on low income households at no cost by enrolling low income households in community solar. By having all low income households be automatically enrolled, all would benefit. RECOMMENDATION: For City properties, the CCWG recommends that all City properties utilize on-site solar power generation. Additionally, City meters should be enrolled in the Community Shared Solar (CSS) available across the State since 2014 and now operated under the State’s’ SMART program - this would both save money and increase energy efficiency of municipal properties. Additionally, the City should opt- in low income households to CSS under CCE as described above... This way, Cambridge would benefit from facilities that have already been built by private companies under the State’s SMART program without any investment or installation. 15

RECOMMENDATIONS: See below for a list of actions that were discussed by transportation experts within the CCWG: Transition to an all electric municipal fleet with an aggressive timeline. ◊ Strengthen and codify the current Green Fleet Policy in ordinance. ◊ As soon as an EV is available, all new purchases should be EV - with an expected complete replacement for passenger vehicles and light commercial vehicles by 20302; the city’s medium and heavy duty fleet should transition by 2035. Ensure that all leased and owned school buses are electric vehicles are EVs. Electrification ◊ Create an aggressive plan for the expansion of EV charging infrastructure. • Build off of other cities with EV goals, like Boston. ◊ Utilize all existing options - light pole charging, public lot chargers, right to charge, allow private residences to lease their chargers to the public. ◊ 100 more publicly available EV chargers should be installed in the next 5 years and goal established for next 5 years • Create a comprehensive plan with community input. • Require consideration of equity in terms of the placement of chargers. Reduce vehicle traffic and expand bike and pedestrian infrastructure to ensure safe cycling and walking for citizens. ◊ Bike parking infrastructure that provides bikes protection from elements 4. Transportation: incentivize non- auto transportation and EVs and accelerate adoption: Transportation is the second largest source of emissions in Cambridge and the largest source statewide. In addition to emissions reduction, reforming transportation in Cambridge would reduce noise and air pollution (which has a disproportionate impact on low income neighborhoods), congestion, and deaths and injuries resulting from crashes. It is critical to expand mobility options for all citizens of Cambridge to promote alternatives to private vehicles. While Cambridge does not control every road within the city limits and many commuters simply travel through Cambridge, there are concrete steps that can be taken in the immediate term that would reduce transportation emissions and make Cambridge a safer, greener, healthier, and more equitable City. 16 2 NYC, with the largest municipal fleet in the country, has set this goal.

enables more residents to own bikes. • Public bike parking should be installed in residential neighborhoods. • Explore options like secure bike parking pods. ◊ Provide options including rebates and funding to make bikes, e-bikes, and bike shares more affordable to low income residents • Include concrete initiatives for expansion of e-bike use • Review bike-share use and expand access and establish targets to serve all residents with station proximity ◊ Bus and bike lane infrastructure - work with city and MBTA to expand past efforts and provide a fare free transit pilot by the summer of 2022. Engaging all stakeholders, explore vehicle free and low and zero emission zones to reduce emissions and inequity in air quality; make this a priority in working with the state to move forward and seek funding to implement ◊ Example3: delivery and curb management. Heavy duty vehicle Deliveries increases air pollution, traffic, safety risks, and idling, - consider if there are emission free ways to deliver, like the utilization of cargo bikes, increase anti-idling efforts Fare free transit: support city efforts to expand on pilot and work with state to extend to more public transit, including microtransit, and enhancing pedestrian and cycling opportunities connecting with transit. End parking minimums and encourage parking maximums. ◊ End parking minimums and institute parking maximums to move Cambridge towards a less car-oriented city. 17 3 Urban deliveries are projected to increase 78% by 2030, increasing emissions by 30%

5. GeoGrids: Cambridge should actively pursue and install a demonstration: The transition to electrification is an urgent need to meet climate goals. Currently the only way to decarbonize is to electrify and have renewable electricity. With buildings the largest contributor to GHG emissions, heating and cooling buildings have been a focus of efforts. The Cambridge-based Home Energy Efficiency Team (HEET), led by co-executive directors Audrey Schulman and Zeyneb Magavi, has provided a potential way to accomplish this goal. HEET proved its capability by mapping thousands of dangerous gas leaks across the state, highlighting that the need to move away from natural gas as quickly as possible is both a matter of climate emergency as well as public safety. Networked ground source heat pumps represent a viable path towards transitioning away from natural gas. HEET’s GeoGrid4 : a system of networked ground source heat pumps, structured like a gas system to provide heat to an entire district, was reviewed by the CCWG. The infrastructure is installed in the street, with pipes going into every building. The only emissions come from electricity used, so any building connected would immediately reduce emissions and as the grid was greener, get to net zero or zero emissions. This type of system could meet 100% of energy needs - in some cases, even resulting in excess energy the initial results of installations show where it has been installed the system is cleaner, cheaper in the long-term, and healthier for residents. The impact of implementing wide scale GeoGridsis potentially monumental. The CCWG asked Councillor Nolan and the Mayor to push for Cambridge as a pilot site for Eversource to install a GeoGrid, and a policy order resulted. RECOMMENDATION: Since Cambridge was not selected for the first Eversource demonstration installation, the city should find a way to do a pilot installation, either using city funds for one or more sites in Cambridge or having a third party company install, own, and maintain the system. A pilot site should be chosen to maximize impact and equity - the densest parts of the city deserve the potential financial savings and health benefits of eliminating gas with its attendant adverse health effects. The idea is to work with Eversource and HEET to structure a pilot. 18 4 https://heet.org/geomicrodistrict-introduction/

6. Use all means possible to limit new fossil fuel infrastructure: The CCWG has endorsed an idea to amend the special permit process in Cambridge, making it more difficult for new construction to use fossil fuel infrastructure. Since the CCWG concluded this work, the Attorney General has opined that this approach was not in line with the state building code. The question is whether there is any path for Cambridge to incentivize developers and builders to have no new fossil fuel in their buildings through the special permit process. This proposal from Brookline activists, who had tried to institute a ban on all new gas or fossil fuel connections in 2019, appeared feasible until very recently when the AG ruling was issued. Despite a well reasoned, clear legal rationale that it could work, in light of the AG ruling, Cambridge would need to file a home rule which may or may not be approved. Attention on this question of requiring no new fossil fuel infrastructure is now directed to the stretch energy code update in draft [straw] proposal form. The current climate actions as written into ordinance and the Net Zero Action Plan are not sufficient to reach our emissions reduction goals, and new buildings are in planning now, making new and more aggressive plans crucial in the climate emergency. The state has released the net zero stretch energy code draft, and it will not do enough. The City Council and the City have advocated for a better code and should encourage all stakeholders to follow suit. RECOMMENDATION: Pursue the Special Permit route to ending new fossil fuel infrastructure in large buildings, and work with the legal department on whether there is a way to craft an incentive system that could pass legal review. And advocate at every level for a strong, true net-zero stretch code that would allow municipalities to mandate all new buildings and major renovations decarbonize. 19
