The report proposes optimizing the limited supply of sustainable aviation fuel (SAF) by targeting its use at airports with the highest contrail and particulate matter (PM) impacts. Analysis of 16.6 million flights in 2024 reveals that 2% of flights generate 80% of contrail-related warming. In the U.S., JFK, LAX, and O'Hare are identified as primary targets, while Heathrow, Istanbul Airport, and Paris CDG are the top candidates in Europe. The study finds that a 50% SAF blend can reduce LTO particulate emissions by 26-28% and contrail-related warming by 30-40%. While airport-wide targeting is simplest, time-based and flight-based strategies are more fuel-efficient. Implementation faces logistical hurdles, particularly at airports using hydrant fuel systems, but the report suggests these can be overcome through policy incentives and infrastructure investment.

The guide outlines ten ways US cities can advance electric mobility through permitting reform, building codes, targeted public charging, and shared e-mobility services to ensure an equitable transition.

Climate Central analysis indicates that climate change increases the probability of performance-impairing heat (above 28°C) for 97 out of 104 scheduled 2026 World Cup matches. Nearly half of the matches face at least a 50% chance of such heat, with the highest impact seen in the June 26 match in Guadalajara. To mitigate health and performance risks, organizers have implemented mandatory hydration breaks and increased evening matches, though only three stadiums (Atlanta, Dallas, and Houston) are fully climate-controlled.

Climate Central analysis shows that 14 of the 16 host stadiums for the 2026 World Cup are experiencing more extremely hot days during the June-July tournament period than in 1970. Human-caused climate change is responsible for an average of 49% of these extreme heat days across all stadiums, with the highest impact seen in Miami and Mexico City. In 10 repeat host cities, the frequency of extremely hot days has tripled on average since they last hosted the tournament.

The Multi-Family Housing Tracker documents the significant increase in private equity ownership of U.S. apartment complexes, noting that 228 identified firms own nearly 3 million units, or approximately 13% of the national total. The report highlights a heavy concentration in Sunbelt states and metropolitan areas, correlating these regions with sharp increases in 'cost-burdened' renters. It details a business model focused on rapid value increases through rent hikes and additional fees, while documenting widespread tenant complaints regarding poor maintenance, aggressive evictions, and the use of algorithmic pricing software like RealPage. The document concludes with recommendations for landlords, public officials, and institutional investors to implement rent caps, just-cause eviction protections, and responsible investment standards.

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.

The report finds that rents for the lowest-cost unsubsidized market-rate housing (workforce housing) increased by 20.2% nationally between 2021 and 2025, more than double the 9.2% increase for luxury (discretionary) housing. This trend is most pronounced in the Sunbelt region, where corporate landlords, including private equity firms, target workforce housing as a low-risk, high-cash-flow investment. The document highlights a crisis of evictions and 'self-evictions' driven by these price hikes and argues that government-sponsored enterprises (GSEs) like Fannie Mae and Freddie Mac facilitate this corporate takeover by providing easy financing with few tenant protections. It recommends policy interventions such as rent control, just cause eviction laws, and the adoption of investment standards for public pension funds.

The E-Bike Rebate Program Guidebook by RMI outlines a five-step process for establishing e-bike incentive programs: identifying goals, designing funding and incentive structures, partnering with bike shops, conducting community outreach, and managing program launch and evaluation. It emphasizes equity through income-tiered rebates and point-of-sale models, while highlighting the importance of supportive infrastructure and diverse funding sources such as general funds, grants, and utility partnerships.

The report argues that the Opportunity Zone program, created by the 2017 Tax Cuts and Jobs Act, serves as a subsidy for private equity firms rather than a tool for community redevelopment. PESP identified $16.2 billion raised for Qualified Opportunity Funds (QOFs) by approximately 200 firms, with Bridge Investment Group Holdings, CIM Group, and Griffin Capital Company among the top beneficiaries. The document details how firms profit via capital gains tax deferrals and annual management fees, often ranging from 1.25% to 2%. Case studies in Los Angeles, Atlanta, and Arizona suggest the program encourages the development of luxury housing and the displacement of low-income residents through 'substantial improvement' requirements that necessitate evictions. The report also highlights political ties between major QOF investors and the Trump administration, and criticizes the lack of federal reporting requirements to track the program's actual impact on poverty.

The report examines the 'Gulch' redevelopment project in downtown Atlanta, where the city provided significant tax breaks to the LA-based private equity firm CIM Group. It highlights that CIM Group reneged on its affordable housing commitments in October 2024, opting instead to pay an $8 million fee that advocates claim was based on outdated figures. The text frames this as part of a broader pattern of private equity infiltration in Atlanta's housing market and calls for greater city official accountability in vetting corporate partners.

The report examines the 'Centennial Yards' (formerly the Gulch) redevelopment project in Atlanta, where the City provided nearly $2 billion in tax breaks to the LA-based private equity firm CIM Group. It highlights CIM's decision in October 2024 to renege on affordable housing promises by paying an $8.5 million 'in-lieu' fee, which critics argue is based on outdated 2017 data. The document further details CIM's controversial track record in other cities, including allegations of predatory behavior at Southern Towers in Alexandria, Virginia, and driving gentrification in the West Adams neighborhood of Los Angeles.

Climate Central's analysis of 198 U.S. cities shows that 87% have experienced longer freeze-free growing seasons since 1970, increasing by an average of 20 days. This trend, driven by carbon pollution and warming, extends the period plants release pollen, worsening seasonal allergies for millions, including approximately 19% of U.S. children. The report highlights that CO2 levels also boost pollen production, potentially increasing it by 200% by the end of the century, with disproportionate health impacts on Black and Puerto Rican children who face higher asthma risks.

The report examines the link between urban sprawl and high energy consumption, arguing that current energy policies overlook the role of urban design. It advocates for "complete communities"—dense, walkable, mixed-use neighborhoods—as a primary strategy for emissions reduction. Using the Sustainable Asset Valuation (SAVi) methodology, the report compares car-centric and sustainable transportation scenarios in Winnipeg, finding that sustainable shifts offer significantly higher net benefits and a superior benefit-to-cost ratio. It identifies key barriers such as NIMBYism, flawed municipal governance, and the financial instability caused by sprawl, while proposing solutions including zoning reform, parking policy changes, and new municipal revenue tools.

The report argues that private equity firms prioritize high returns (at least 15%) over short timelines (3-5 years), leading to deferred maintenance and increased tenant instability. It proposes a toolkit of interventions, including rental registries with beneficial ownership disclosure, just cause eviction protections, landlord licensing with portfolio caps, and right of first refusal legislation. The document also examines federal legislative attempts to curb consolidation through tax penalties and transfer taxes, while highlighting the challenge of state preemption of local housing justice measures.

The Infrastructure Investment and Jobs Act (IIJA) and Inflation Reduction Act (IRA) provide substantial funding for U.S. public transit and clean energy, including $91.9 billion for transit via the IIJA and $12.3 billion for transportation via the IRA. Key programs include the Urbanized Area Formula Grants, the State of Good Repair Formula Grants, and the Neighborhood Access and Equity (NAE) program. However, the analysis suggests a continued reliance on car-centric infrastructure, with $307 billion of combined transportation funding directed toward roadway planning and development, potentially undermining climate goals and equity through induced demand and the prioritization of personal electric vehicles over mass transit.

The guide outlines strategies for educators to embed climate change solutions into diverse subjects, from K-12 to graduate school. Key recommendations include utilizing local examples, inviting diverse guest speakers to demonstrate various career pathways, using simulations and games, and encouraging student-led projects and engagement with local government. The author emphasizes the importance of science-informed optimism and helping students find their personal purpose within the climate movement.

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.

The United States saw a 60% increase in major weather-related power outages during the heat season between 2014-2023 compared to 2000-2009. The South region experienced the highest number of these events, with Texas and Michigan recording the most outages at the state level. These outages compound health risks for vulnerable populations, such as the elderly and children, particularly when overlapping with extreme heat waves. Proposed solutions for grid resilience include the implementation of microgrids, smart grid technologies, and physical hardening of infrastructure.

The document argues that current EV charging infrastructure is concentrated in high-income areas, creating a barrier to adoption for lower-income multifamily housing residents. Based on engagement in Portland, Atlanta, and Phoenix, it recommends that stakeholders prioritize community engagement, affordability, multimodal solutions, and inclusive local partnerships to ensure an equitable transition to transportation electrification.

WWF's 2024 review highlights efforts to combat climate change and biodiversity loss through targeted programs. Key achievements include expanding the Food Waste Warriors program to 15 new cities, enrolling 1 million acres in the Ranch Systems and Viability Planning network, and contributing to a global tiger population increase to 5,574. The report also details human-wildlife conflict mitigation in the KAZA region, elephant tracking in India, and the establishment of the Tribal Buffalo Lifeways Collaboration in North America.
