Analysis of cooling degree days (CDD) shows that 97% of 241 major U.S. cities experienced increased cooling demand since 1970, with an average increase of 37%. This trend, combined with a 31% rise in residential electricity prices between 2020 and 2025, increases the financial burden on households, particularly low-income families. In 2020, the ten states with the highest cooling costs saw average household expenditures between $378 in Hawaii and $712 in Arizona. Future projections suggest U.S. household cooling demand will rise 43% by 2050. The report also highlights systemic risks, including electricity grid strain, increased carbon emissions from fossil-fuel-reliant cooling, and the urban heat island effect caused by waste heat from air conditioners.

The report introduces Green Economic Populism (GEP), a framework that argues the affordability crisis is a structural challenge intensified by the climate crisis. It posits that reducing dependence on volatile fossil fuels can lower costs for working people across energy, food, health, housing, and transportation. The document provides polling data showing that 70% of US voters believe economic policy can simultaneously lower costs and reduce emissions, and 55% want coordinated policies to address both. It highlights successful political campaigns and labor actions in cities and states such as New York City, Seattle, New Jersey, Georgia, and Missouri that centered the intersection of climate action and material needs, such as rent stabilization, utility price controls, and decarbonized public infrastructure.

The report finds that anthropogenic climate change has significantly increased the probability of dangerous humid heat during the 2026 FIFA World Cup compared to 1994. Using Wet Bulb Globe Temperature (WBGT) as a metric, the analysis indicates that more games are expected to exceed the 26C and 28C thresholds recommended by FIFPRO for cooling breaks and postponement, respectively. While air-conditioned stadiums may mitigate risks for players, spectators at outdoor events remain vulnerable. The study concludes that without substantial adaptation and rapid mitigation of fossil fuel use, hosting summer tournaments in the northern hemisphere will become increasingly hazardous.

Washington State faces escalating risks from drought, wildfires, extreme heat, and coastal flooding, which threaten its economy, ecosystems, and critical US military installations. While federal agencies like NOAA and FEMA provide essential forecasting, funding, and disaster recovery services, the report argues that recent and proposed budget cuts for FY2026—including the termination of key research laboratories and the reduction of grant programs—significantly degrade the state's capacity to prepare for and respond to these hazards.

Climate Central analysis of 221 marathons indicates that the probability of optimal, cool race-day temperatures is decreasing due to global warming. For recreational runners in the U.S., the current average chance of optimal temperatures is 27%, and this is projected to decline in 46 of 51 analyzed U.S. marathons by 2045 if high levels of heat-trapping pollution continue. The analysis highlights regional disparities, with the Northwest having the best current odds (55%) and the Southwest the worst (14%). Beyond performance, the document notes that rising heat and humidity increase risks of heat-related illness and that climate-driven air quality issues, such as wildfire smoke, further threaten runner health.

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 Private Equity Stakeholder Project and United Farm Workers argue that Instar Asset Management has violated the PRI's integrity by ignoring labor abuses at Windmill Farms, including wage theft, gender discrimination, and union-busting, despite Instar's public ESG policies.

Climate Central analyzed cooling degree days (CDD) across 243 U.S. locations, finding that 95% experienced increased cooling demand during the back-to-school period (July 17 to September 8) since 1970. Over the last decade, human-caused climate change increased this demand by approximately 34%. The report highlights that extreme heat negatively impacts children's learning and health, while many U.S. schools lack the necessary HVAC infrastructure to adapt to these rising temperatures.

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 report advocates for a strategic shift in US state transportation policy, moving away from highway expansion toward the reduction of vehicle miles traveled (VMT). It highlights that while vehicle electrification is progress, it is insufficient on its own to meet climate goals. RMI analysis suggests that a 20% reduction in per-capita VMT by 2050 could prevent 6,000 annual fatalities, save $259 billion in annual costs, and avoid 2.3 gigatons of carbon dioxide equivalent. The document urges states to utilize funding from the Bipartisan Infrastructure Law (BIL) for transit, micro-mobility, and 'complete streets' rather than projects that induce more traffic.

The document argues that limiting global temperature rise to 1.5°C requires an immediate stop to burning fossil fuels, urging governments to halve global fossil fuel use by 2035 and stop new fossil fuel project investments. It highlights the role of cities and businesses in this transition, noting that solar and wind are already cheaper than new fossil gas electricity in most C40 city locations. Examples of city-level action include fossil gas bans in new buildings in several US cities and renewable energy targets in Los Angeles, Mexico City, and Seoul. Additionally, over 200 companies with nearly US$1.5 trillion in revenue are calling for clear phase-out timelines, 100% decarbonised power, and the reform of fossil fuel subsidies.

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.

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 document details a multi-stakeholder approach to ending plastic pollution, emphasizing source reduction, reuse systems, and Extended Producer Responsibility (EPR). It advocates for a full life cycle approach that integrates environmental justice and data transparency to inform policy at local, state, and federal levels in the United States, while aligning with an upcoming global plastics treaty.

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 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 document examines the dual role of U.S. ports as both victims of climate change (facing sea level rise and extreme storms) and contributors to it through significant greenhouse gas and pollutant emissions. It details mitigation strategies such as electrification of machinery, shore powering for berthed ships, and the adoption of renewable energy. It also discusses adaptation measures, contrasting 'gray infrastructure' like seawalls with nature-based solutions such as mangrove restoration and living shorelines. The brief highlights specific initiatives at ports in Los Angeles, Long Beach, Savannah, Miami, and others, while noting the role of EPA programs and international certifications in driving sustainability.

The document examines the dual role of U.S. ports as both significant emitters of greenhouse gases and vulnerable infrastructure facing climate threats like sea level rise. It details mitigation strategies, including electrification of machinery and shore powering for ships, and adaptation methods, such as nature-based shoreline protection and improved stormwater management. The brief highlights specific initiatives at ports in California, Georgia, and Florida, while noting the importance of federal resources like the EPA Ports Initiative in supporting these transitions.

The report identifies 90 advertising and PR companies working for the fossil fuel industry, highlighting a conflict between the sustainability pledges of major holding companies and their continued representation of high-polluting clients. It details specific case studies of disinformation and lobbying efforts in the US, Australia, and the EU, while warning that the term 'Net Zero' is being used as a primary tool for greenwashing ahead of the 2021 Glasgow climate talks.

The briefing highlights that transportation is the largest source of greenhouse gas emissions in the US, driven by a reliance on personal vehicles and sprawling land use. It asserts that reducing vehicle miles traveled (VMT) by 20% by 2030 is necessary to limit warming to 1.5°C, regardless of electric vehicle adoption. The author proposes a combination of smart growth development, transportation pricing signals, and roadway redesign to achieve these reductions, noting that an integrated transportation demand management (TDM) plan can compound these benefits.
