The report finds that electrification retrofits for mid-sized commercial office buildings are cost-effective when tailored to regional climate conditions and gas utility rates. By analyzing a prototypical 50,000 square foot building, the study demonstrates that combining heat pump replacements with complementary measures—such as ventilation efficiency, peak demand management, and rooftop solar—can result in positive net present value compared to replacing gas equipment in kind.

The guide explains that Community Project Funding (CPF), a form of discretionary spending available to U.S. senators and representatives, provides a flexible alternative to competitive federal grants for local climate action. It highlights the case of Cohoes, New York, which used $3 million in CPF to build a 3.2 MW floating solar array, and provides strategic advice for communities to secure similar funding by engaging representatives early and focusing on shovel-ready, community-supported projects.

The guide outlines five strategies for cities to leverage utility franchise agreement renegotiations: incorporating climate strategies, planning for equity, investing in resilient infrastructure, embracing collaboration, and understanding negotiation leverage. It highlights specific examples, such as San Diego's climate equity fund and Colorado's powerline undergrounding, to demonstrate how cities can align utility operations with community-wide clean energy goals.

The document catalogues endorsements of the term 'climate emergency' across different sectors. It notes that nearly 14,000 scientists from 156 countries have signed a warning stating 'planet Earth is facing a climate emergency'. In the media, The Guardian updated its style guide to recommend terms like 'climate emergency, crisis or breakdown', and Noticias Telemundo adopted 'climate emergency' over 'climate change' in 2019. Politically, 23 national governments, including Japan, South Korea, New Zealand, and the European Union, have declared a climate emergency, alongside 2,060 towns, cities, and counties globally. Additionally, the UN Secretary General and Pope Francis have called for emergency declarations, and a 2021 poll indicated that two-thirds of the global population views climate change as a 'global emergency'.

Cincinnati is developing a local electric transportation ecosystem involving the manufacturing of electric step vans by Workhorse and their adoption by Servall Electric. Servall is transitioning its fleet of 25 to 30 vehicles to electric and participating in the Run on Less – Electric (RoL-e) demonstration. The transition has resulted in a 75 percent reduction in daily fuel costs, dropping from approximately $60 for gas to $15 for electricity. Beyond financial savings, the electric trucks offer driver benefits such as 'one pedal driving' via regenerative braking and a lower vehicle architecture that reduces physical strain on drivers. The document also notes that urban last-mile delivery emissions in the top 100 global cities could increase by over 30 percent by 2030, reaching 25 million tons of CO2 annually.

The document contends that continued investment in US gas distribution infrastructure is counterproductive to climate goals, as the transition to electric appliances will likely leave these systems underutilized. It argues that low-carbon gases like hydrogen and biomethane are too expensive for residential and commercial use and should be reserved for industrial applications. Furthermore, it suggests that electrification and targeted leak detection are more cost-effective ways to reduce methane emissions than massive pipeline replacement programs, which risk creating stranded assets and imposing high costs on consumers.

Climate Central developed an Urban Heat Intensity Index for 159 U.S. cities, finding that New Orleans, Newark, New York City, Houston, and San Francisco have the highest intensity scores. The report identifies albedo, lack of greenery, population density, and building height as primary drivers of the UHI effect. These conditions exacerbate heat waves, worsen air quality through ground-level ozone formation, and disproportionately affect vulnerable populations, particularly those in formerly redlined neighborhoods. Proposed solutions include short-term emergency cooling measures and long-term infrastructure changes such as planting trees, installing green and cool roofs, and deploying solar energy.

Climate change is intensifying wildfires in the United States by raising temperatures and drying out forests, while a century of fire suppression has increased fuel loads. These fires cause significant loss of life, property destruction, and high federal costs, while simultaneously releasing greenhouse gases that further accelerate global warming.

The document details how climate indicators from the Copernicus Climate Data Store (CDS) are integrated into the SAVi tool to improve the analysis of infrastructure resilience. It covers a literature review of climate impacts on energy, irrigation, wastewater, buildings, roads, and nature-based infrastructure, providing specific equations to link climate variables to asset performance. The report includes simulation results for Johannesburg, South Africa, demonstrating how climate variables like temperature and precipitation affect load factors, thermal efficiency, and maintenance costs, ultimately impacting the economic viability and societal costs of these assets.

The document details how authoritative climate data from the Copernicus CDS is integrated into the SAVi model for nature-based infrastructure. It provides a literature review on the impacts of precipitation, vegetation, and temperature on assets like green roofs, wetlands, and urban forests. The report demonstrates the model's application through simulations in Johannesburg, showing how temperature affects phosphorus removal in wetlands and how increasing vegetation cover can mitigate heat-related labor productivity losses.

The document highlights that older adults are disproportionately affected by extreme heat due to physiological vulnerabilities and social isolation. It argues that while air conditioning is critical, it can be inaccessible due to poverty or power failures, and its use contributes to further warming. The report emphasizes that social connection is a primary defense against heat deaths and details successful community interventions in cities like Philadelphia and Phoenix, while warning that the COVID-19 pandemic exacerbates risks by increasing isolation.

The report documents a crisis where approximately 77,000 people in federally assisted housing live on or near Superfund sites, arguing that environmental racism has historically driven the siting of affordable housing in contaminated areas. It identifies critical failures in interagency coordination between HUD and the EPA, including a lack of resident notification and inadequate housing inspections. Through case studies in East Chicago, Portsmouth, and other cities, the report illustrates the health impacts of lead and arsenic exposure and the struggle for community-led relocation. It concludes with comprehensive recommendations for interagency accountability, mandatory hazard disclosure, and the integration of health interventions for exposed residents.

The brief supports the Bag Waste Act's ban on plastic carryout bags but challenges specific DEC regulations that exempt 'reusable bags' made of plastic thicker than 10 mils. Amici argue this contradicts the legislative intent to ban 'any plastic carryout bags' and is arbitrary and capricious based on evidence that thickness thresholds fail to reduce plastic waste. The brief also rejects claims that the COVID-19 pandemic justifies invalidating the Act.

The policy brief contends that the COVID-19 pandemic accelerated existing vulnerabilities in the U.S. fossil fuel industry, making a fair transition for workers urgent. It advises against using federal stimulus for fossil fuel assets, suggesting instead that investments be directed toward low-carbon infrastructure, which creates more jobs per million dollars spent. The author proposes a four-part framework for a fair transition: accounting for automation and digitization, planning proactively across all carbon-intensive industries, recognizing that clean energy jobs may not be a direct replacement for all fossil fuel roles due to geographic and skill gaps, and employing bottom-up, community-led investment strategies.

The author advocates for integrating urban forests into Canada's national tree-planting goals, highlighting their role in carbon sequestration, heat reduction, and flood mitigation. The text emphasizes that urban tree success depends on biological diversity, connectivity, and long-term maintenance rather than just the number of trees planted.

The report finds that ride-hailing typically increases climate pollution and urban congestion because it displaces lower-carbon travel modes and adds 'deadheading' miles. It argues that the industry must rapidly electrify its fleet and increase ride-pooling to mitigate these effects, while governments should prioritize multimodal transportation and mass transit over car-centric models.

The report analyzes the climate impact of transportation network companies (TNCs) in seven major U.S. cities. It finds that non-pooled ride-hailing trips emit 47% more than private vehicle trips of the same length, largely due to 'deadheading' (driving without passengers). When accounting for the modes of transport that ride-hailing displaces—including mass transit, walking, and biking—typical ride-hailing trips are approximately 69% more polluting than the trips they replace. The analysis suggests that a transition to electric vehicles and an increase in pooling rates to 50% could reduce these emissions by 52% relative to displaced trips.

The briefing introduces 'hours-of-safety' to measure how long a home remains at a comfortable temperature after power is lost during extreme weather. It highlights the life-threatening risks of heat waves and polar vortexes, particularly for vulnerable populations in poorly insulated housing. The author advocates for passive design strategies—such as improved insulation, tighter envelopes, and cool roofs—combined with islandable solar PV and battery storage to increase passive survivability and community resilience.

The Union of Concerned Scientists and a coalition of stakeholders established six policy principles for energy storage to ensure the transition to clean energy benefits disadvantaged and frontline communities. These principles focus on reducing emissions, improving disaster resilience, promoting local economic development through job training, accelerating renewable energy deployment, protecting consumers from high costs, and ensuring transparent community participation in project planning.

The document outlines a systemic approach to urban freight management, combining a set of Key Performance Indicators (KPIs) with a library of global best practices. It argues that urban logistics efficiency is driven by a combination of land-use planning, infrastructure investment, and regulatory flexibility. Key strategies discussed include the use of ring roads to divert through-freight, the implementation of urban consolidation centers, and the transition to zero-emissions vehicles. The report emphasizes the necessity of data-driven decision-making through GPS logs and stakeholder engagement via Freight Quality Partnerships to reduce the high costs of the 'final mile' and improve city livability.
