The toolkit addresses 'green gentrification,' where green infrastructure investments increase property values and spur real estate speculation, leading to the displacement of vulnerable populations. It proposes a multi-layered approach combining tenant protections, land-use regulations, funding alignment, economic opportunity enhancement, community ownership, and inclusive design to ensure that the benefits of urban greening are shared equitably without harming existing residents.

The Carol Avenue Apartments in Boston are undergoing a deep energy retrofit scheduled for completion in late 2024. The project focuses on transitioning a 33-unit, 1910-era property from fossil fuel-based systems to a fully electric infrastructure. By combining interior wall insulation, roof upgrades, and the installation of a Variable Refrigerant Flow (VRF) system, the property is estimated to reduce energy use by 55 percent. The addition of 65.3 kW of rooftop solar PV is projected to further increase total energy reduction to 64 percent and reduce greenhouse gas emissions by 41 percent.

The Hano Homes project in Boston aims to transform a multifamily residential building constructed in 1888 into a net-zero energy property through a deep energy retrofit planned for 2023–2024. The strategy involves wrapping the building in a superinsulated exterior shell, replacing gas boilers and water heaters with all-electric heat pump systems, and installing a 100–110 kW rooftop solar PV system. These measures are expected to reduce energy usage by 69% and eliminate operational greenhouse gas emissions, while the use of bio-based insulation is intended to store carbon and reduce embodied emissions.

The paper examines the historical relationship between human settlements and their environments, contrasting traditional sustainable systems with modern industrial disengagement. It proposes a new regionalism in architecture that uses climatic data to inform design and advocates for 'ecological utilities'—buildings designed primarily to repair and rebuild the environment by providing ecosystem services such as carbon sequestration, water remediation, and soil regeneration.

The report identifies a significant gap in energy efficiency within US affordable housing, noting that public housing is 38% more inefficient than private residential buildings. It categorizes barriers into programmatic (regulatory and information gaps), financial (funding backlogs and complex mixed-financing), technical (lack of integrative design and energy modeling), and operational (tenant incentives and lack of retro-commissioning). To address these, the report recommends streamlining HUD's Energy Performance Contract (EPC) processes, adopting life-cycle cost analysis, utilizing a 'whole-building' design approach, and implementing retro-commissioning, which can reduce energy consumption by a median of 16% with a fast payback period.

The Stockholm Environment Institute (SEI) is an international non-profit research organization that integrates scientific research with policy analysis to promote sustainability. Operating through eight global centers, SEI focuses on climate change, water, air, and land use, while incorporating perspectives on governance, economics, gender, and human health. Its regional centers provide specialized expertise in areas such as sustainable urbanization in Africa, climate adaptation in Asia, and environmental governance in the Baltic region and European Union.

Since 1970, the Northeast has seen an average temperature increase of 2°F, leading to longer growing seasons and reduced snowpack. Future high-emissions scenarios project further warming, significant reductions in winter snow seasons, and increased frequency of extreme heat and flooding. These changes threaten the dairy and fruit industries, particularly cranberries, and risk substantial damage to coastal infrastructure in cities like New York and Boston. Additionally, the region's $7.6 billion winter recreation industry and specific fisheries, such as cod and lobster, face disruption due to warming waters and reduced snow cover.

A WWF study of 46 US schools found that students waste an average of 39.2 pounds of food and 28.7 cartons of milk annually. This translates to an estimated $1.7 billion in national annual losses. The report highlights that milk waste is particularly high due to misconceptions about USDA reimbursement rules and the use of cartons over dispensers. It proposes that reducing waste—even by a conservative 3%—could provide significant funding for initiatives like Farm to School (F2S) and the Good Food Purchasing Program (GFPP), which improve student nutrition and support local economies.
