The document outlines a four-step process for utility climate risk planning: identification, quantitative assessment, mitigation, and risk distribution. It emphasizes the need for utilities to move beyond siloed resilience plans by incorporating both physical risks (e.g., extreme weather) and transition risks (e.g., carbon taxes, policy changes) into core planning documents like Integrated Resource Plans (IRPs). The authors advocate for the use of high-resolution, long-term climate datasets (30+ years) to accurately model extreme events and argue that clean energy portfolios reduce financial volatility for residential customers compared to fossil-heavy portfolios. Finally, it provides actionable recommendations for regulators to mandate risk assessments, create financial incentives for transitioning away from fossil assets, and explore self-insurance funds to protect low- and middle-income customers from catastrophic costs.

The document explores the 'climate-crime nexus,' detailing how environmental stresses drive rural petty crime, urban violence, drug use, gender-based violence, hate crimes, trafficking, and white-collar crime. It highlights how climate-induced economic collapse and extreme heat increase desperation and aggression, while the green transition creates new opportunities for organized crime and corruption.

The Community Guide to Cumulative Impacts explains how to identify and quantify the combined effects of multiple pollutants and social stressors on public health. It details existing state and city laws in the US that allow regulators to deny permits based on cumulative impacts and provides a framework for community organizing, including drafting model legislation and using environmental justice mapping tools.

A coalition of advocates argues that the EPA's disparate impact regulations under Title VI of the Civil Rights Act of 1964 are essential for protecting marginalized communities from disproportionate environmental harms. The document details systemic environmental racism, provides case studies of both successful and failed civil rights enforcement, and urges the EPA to strengthen rather than roll back these protections.

A late summer heat event in the eastern United States, affecting approximately 120 million people, has been made significantly more likely by human-caused climate change. The event is characterized by record-breaking temperatures, high humidity, and heat indices reaching 115°F, posing severe health risks to vulnerable populations, particularly children.

Climate Central analyzed the urban heat island (UHI) index across 65 major U.S. cities, finding that 68% of the 50 million residents in these cities live in areas where the built environment increases temperatures by 8°F or more. The study identifies albedo, green space, and population density as the primary drivers of this effect. It also highlights a link between historical redlining and current heat disparities, noting that in 84% of 179 analyzed cities, historically redlined areas experience hotter summers than non-redlined areas.

Wisconsin taxpayers will need to spend at least $16.7 billion through 2040 to protect communities from climate change, with municipal governments bearing the vast majority of these costs ($14.1 billion). The most significant expenses include improving stormwater management ($6.67 billion) and proactive road maintenance ($5.09 billion). The report highlights that these costs fall disproportionately on high racial minority areas and low-education rural communities, potentially consuming a significant portion of local public works budgets. It argues that fossil fuel companies should be held legally accountable for these damages.

RMI analysis indicates that Illinois households could save over $2,800 annually by implementing a combination of vehicle electrification standards, climate-driven agency planning, and renewed transit investments. These strategies could reduce pollution by up to 305 million metric tons between 2024 and 2050 and prevent thousands of deaths annually through reduced crash fatalities, improved air quality, and increased physical activity. While Illinois has received federal funding via the Bipartisan Infrastructure Law and Inflation Reduction Act, the report notes the state has yet to adopt clean vehicle standards or integrate climate metrics into infrastructure project scoring.

Analysis by Climate Central indicates that carbon pollution significantly increased the likelihood of abnormally warm winter days across the U.S. from December 2023 to February 2024. Approximately 85% of the U.S. population experienced at least one day where warm temperatures were at least twice as likely due to climate change. The Midwest experienced particularly strong climate fingerprints, with Minneapolis showing the largest warm departure from normal temperatures among 487 global cities with populations over 1 million. San Juan, Puerto Rico, recorded the highest number of days influenced by climate change at Climate Shift Index level 2 or higher.

The Great Lakes have seen a 25% decrease in basin-wide ice cover since 1973, with all five lakes experiencing shorter ice durations. This trend, mirrored across the Northern Hemisphere, is linked to warming winter air and contributes to increased lake-effect snow, altered fish species competition, and risks to cultural heritage and safety. While natural patterns like El Niño cause year-to-year variability, long-term projections suggest further ice loss and surface water warming this century.

The guide outlines how state, local, and tribal governments can utilize CPRG funding to reduce methane emissions by implementing upstream organic waste diversion and downstream landfill gas controls. It emphasizes the use of 20-year global warming potential (GWP) for GHG inventories to highlight the urgency of methane action and details specific policy measures, such as organic waste bans and advanced monitoring technology, to achieve rapid emissions reductions and community benefits.

The Great Lakes region—comprising Illinois, Indiana, Michigan, Minnesota, Ohio, Pennsylvania, and Wisconsin—is positioned to drive US aviation fuel targets due to its strong industrial networks and feedstock availability. While the region possesses significant strengths in ethanol supply chains and logistics, a policy gap analysis reveals that no state currently has a comprehensive, coordinated approach to SAF demand and supply. The brief argues that leveraging existing infrastructure, such as the O'Hare International Airport hub and the St. Lawrence Seaway, alongside federal incentives from the Inflation Reduction Act, can catalyze a regional bioeconomy and reduce aviation emissions.

The document argues that the U.S. transition to electric vehicles risks leaving behind low-income, rural, and minority communities due to 'charging deserts' and financial barriers. It outlines five strategies for local governments to ensure equitable access: utilizing community input for siting, prioritizing multifamily housing and charging deserts, expanding urban curbside charging, increasing pricing transparency, and supporting diverse e-mobility modes. The guide emphasizes that overcoming disparities in homeownership and energy burdens is essential for a just energy transition.

The Private Equity Stakeholder Project (PESP) argues that private equity ownership of rental housing increases risks to tenants, citing examples of steep rent hikes, inadequate maintenance, and abusive eviction practices by firms like CIM Group, The Blackstone Group, and Progress Residential. PESP recommends that the FHFA establish a public rental registry for beneficial owners, cap annual rent increases at 3%, mandate habitability standards, and codify tenant rights, including just-cause eviction and the right to organize.

Climate Central analyzed 18,945 census tracts across 44 major U.S. cities, finding that 41 million people (approximately 55% of the analyzed population) live in areas where the urban heat island (UHI) effect increases temperatures by 8°F or more. The study identifies albedo, green space percentage, and population density as the primary drivers of this effect, with New York City exhibiting the highest average UHI index. The analysis categorizes cities by heat patterns—concentrated cores, diffused zones, or sprawling intensity—and highlights that structural inequities often lead to disproportionate heat exposure for people of color and low-income populations.

The report details how Pipeline Health, backed by firms including Stanton Road Capital, Davidson Kempner Capital Management, and Deerfield Management, utilized sale-leaseback transactions and complex subsidiary structures to monetize hospital real estate. It highlights the closure of Westlake Hospital in Illinois, which occurred despite promises to regulators, and the sale of Weiss Memorial Hospital's parking lot for luxury housing. The document concludes that these practices led to Pipeline's own Chapter 11 bankruptcy in 2022 and recommends stricter state and federal oversight of private equity acquisitions of safety net hospitals.

The report details how Pipeline Health utilized sale-leaseback transactions to monetize hospital real estate and employed a complex web of subsidiaries to obscure ownership. It specifically highlights the closure of Westlake Hospital in Illinois, which the report claims was planned prior to acquisition despite assurances to regulators, and the sale of Weiss Memorial Hospital's parking lot for luxury housing development.

The policy brief advocates for linking the U.S. Department of Energy's (DOE) Regional Clean Hydrogen Hubs with clean transportation corridors for heavy-duty trucking and marine shipping. It argues that while hubs provide localized production, corridors act as 'spokes' that expand the market beyond industrial off-takers and improve the economic viability of zero-carbon fuels. The author suggests that coordinating these programs will create a synergistic ecosystem, reduce conventional air pollutants in environmental justice communities, and position the U.S. as an exporter of low-emissions ammonia.

The guide advises consumers to first consider car-free alternatives to reduce costs and carbon emissions. For those who need a vehicle, it recommends the lowest-emission option, noting that EVs produce less than half the lifetime heat-trapping emissions of gasoline cars. It discusses the trade-offs between battery size and cost, explains three levels of charging (Level 1, Level 2, and DC fast charging), and addresses the impact of cold weather on battery range.

The Pembroke-Hopkins Park Energy Efficiency Pilot (PEEP) provides an alternative to fossil fuel infrastructure in rural Illinois by implementing energy efficiency and electrification upgrades in low-income homes. The project, led by the Community Development Corporation of Pembroke and Hopkins Park (CDC-PHP) in collaboration with RMI and other partners, replaces propane and wood heating with electric air source heat pumps and induction stoves while improving insulation. Early results show reduced energy bills and improved indoor comfort for participants. The project aims to serve as a transferable model for other disenfranchised rural communities across the United States by focusing on community trust and relatable examples of clean energy success.
