Analysis of USA National Phenology Network data shows that first spring leaves now emerge earlier in 88% of 242 major U.S. cities, shifting by an average of six days since 1981. This trend, combined with a freeze-free growing season that has stretched 21 days longer on average across 173 cities between 1970 and 2025, extends allergy seasons and increases the risk of 'false spring' crop losses. Ecological disruptions include potential mismatches between bird migration and the peak abundance of food sources.

Climate Central's analysis of 65 major U.S. cities reveals that approximately 76% of the 6.2 million K-12 public school students in these areas attend school in 'extreme urban heat zones,' where the built environment adds at least 8°F of additional heat. The average student in these cities attends school in a neighborhood that is 8.3°F hotter due to the built environment, with the highest average additional heat found in New York City (9.6°F). The report highlights that children are particularly vulnerable to heat-related health risks, which can impair academic achievement and development, while noting that 41% of public school districts need to update or replace HVAC systems in at least half of their schools.

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.

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.

The Ironbound community in Newark, New Jersey, is a vibrant immigrant neighborhood facing significant economic distress, characterized by low median household incomes, high housing cost burdens, and a job market dominated by low-paying service and logistics roles. While employment and average wages have grown since 2015, the community suffers from a mismatch where high-paying jobs are largely filled by non-resident commuters, and residents often work in low-barrier 'Tier 3' occupations that do not provide a living wage. The area also faces environmental burdens from chemical contamination and diesel truck traffic, compounding the social and economic isolation of its residents.

The report analyzes how the energy and transportation sectors drive air pollution in the U.S., noting that while the Clean Air Act has significantly reduced overall emissions since 1970, severe exposure disparities persist. It highlights that people of color and low-income populations are more likely to live in areas exceeding health standards, often near 'pollution hot spots' that current monitoring networks may miss. Through case studies in California, New Jersey, and Indiana, the document illustrates the specific health burdens—including asthma and cancer—borne by marginalized communities living near ports, incinerators, and coal plants.

The report examines the DOE's Community Benefits Plan (CBP) process, which requires grant applicants to commit to equitable community and workforce strategies. While the CBP is credited with forcing developers to prioritize equity and job quality, the report identifies significant challenges, including limited DOE capacity, rushed timelines, and growing stakeholder fatigue. Community surveys reveal deep skepticism due to unfulfilled past promises and a preference for environmental quality improvements over clean energy funding. The report recommends that the DOE improve accountability, provide seed funding for commitments, and leverage other federal agencies to support under-resourced community groups.

The document combines findings from community surveys in New Jersey, Louisiana, and the Navajo Nation with stakeholder interviews to evaluate the Community Benefits Plan (CBP) required for most U.S. Department of Energy (DOE) funding. While the CBP is seen as a tool to improve worker and community outcomes, survey data reveals deep skepticism due to unfulfilled past promises and a preference for environmental quality improvements over clean energy expansion. Implementation challenges include limited DOE capacity, stakeholder fatigue, and a need for greater accountability and resources for under-resourced community groups.

The report examines various legislative attempts to curb the growth of corporate landlords in the US, focusing on strategies to deconsolidate the housing market. It analyzes proposed and enacted measures such as ownership caps in North Carolina, excise taxes in California and Ohio, and right of first refusal laws in California and Colorado. While many of these bills failed in committee due to political opposition, the report highlights successful examples like Los Angeles's 'mansion tax' and Colorado's protections for manufactured housing residents as models for future housing justice efforts.

The analysis concludes that for long-haul heavy-duty trucking, hydrogen fuel cell vehicles (FCEVs) outperform battery electric vehicles (BEVs) in terms of refueling stops, total dwell time, and cargo capacity. While BEVs offer higher energy efficiency, their heavy batteries significantly reduce payload and require a more extensive and larger infrastructure buildout. Infrastructure modeling indicates that a full transition to BEVs would require stations approximately 10 times the size of current diesel stations, whereas FCEV stations, while still larger than diesel, are more comparable, especially if updated safety regulations are adopted. The report suggests that while BEVs will be important for the broader transition, FCEVs are the most efficient strategy for the specific challenges of long-haul heavy-duty transport.

A coalition of environmental justice advocates, including Earthjustice and the New Jersey Environmental Justice Alliance, submitted comments on the New Jersey DEP's proposed Environmental Justice (EJ) rules. The coalition argues for a narrow interpretation of the 'compelling public interest' exception, specifically opposing the use of economic benefits or job creation as justifications for permitting new polluting facilities in overburdened communities. They recommend expanding public notification radii to five kilometers, refining the definitions of 'new facility' and 'incinerator' to include technologies like pyrolysis and gasification, and adopting more sensitive air quality metrics based on WHO guidelines rather than EPA NAAQS. The document also emphasizes that race is the strongest predictor of pollution burden in New Jersey, citing historical redlining and systemic failures in DEP's permitting and enforcement processes as drivers of environmental racism.

The document analyzes the resource requirements and potential externalities of direct air capture (DAC) at both a single-plant (1 MtCO2/year) and a system-wide (0.5 GtCO2/year) scale. It finds that while on-site emissions are low, significant impacts arise from energy demand, land use, and the materials supply chain. The authors argue that responsible scaling requires project-specific social and environmental impact assessments, robust community engagement, and the use of legal agreements like Community Benefits Agreements to ensure equitable distribution of benefits, such as job creation.

The document argues that the EPA's Draft Strategy to Reduce Lead Exposures and Disparities in U.S. Communities is too tentative and fails to commit to the necessary regulatory changes to protect public health. The authors demand the strengthening of the Lead and Copper Rule, the adoption of health-based lead hazard standards for dust and soil, the phase-out of leaded aviation gasoline, and more rigorous cleanup of Superfund sites. They emphasize that lead exposure disproportionately affects communities of color and low-wealth populations, constituting a significant environmental injustice. The coalition calls for a 'whole of government' approach involving the FDA, HUD, and CDC to address lead in food, housing, and pediatric testing.

Climate Central analysis shows that 72% of 246 evaluated U.S. locations have seen an increase in the amount of rain falling on their annual wettest day since 1950, with the most significant increases occurring in the Gulf Coast and Mid-Atlantic. The document links these trends to rising temperatures, noting that for every 1°F increase, the atmosphere holds approximately 4% more moisture. It highlights the severe impacts of these events, including $43 billion in flood damages from 2016-2020 and disproportionate risks for Black, Brown, Indigenous, and poor communities, particularly in redlined areas where flood risk is 25% higher.

The report details how systemic racism in Kansas City has led to the disproportionate siting of polluting industries in communities of color and low-income areas, resulting in severe health disparities. It highlights the failure of federal and state air monitoring networks to capture local pollution 'hot spots' and describes the efforts of CleanAirNow to implement community-based monitoring. The document concludes with recommendations for stricter emissions standards, real-time fenceline monitoring, and the transition to zero-emissions transportation to protect vulnerable residents.

The briefing advocates for a 'Clean Trucks New Jersey' program, combining the Advanced Clean Truck (ACT) and Heavy-Duty Omnibus (HDO) rules to replace diesel trucks with zero-emission vehicles (ZEVs). Based on an MJ Bradley & Associates study, the program is projected to deliver $11.6 billion in societal benefits by 2050, including significant reductions in NOx and PM2.5, avoided premature deaths, and nearly 19 million metric tons of avoided CO2-equivalent emissions. The authors emphasize that while these rules are a start, additional targeted measures are necessary to protect environmental justice communities, particularly in areas like Camden County, Newark, and Elizabeth, which suffer disproportionate pollution impacts.

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 Central's analysis of U.S. weather data from 1970 to 2018 reveals a broad warming trend, with 91% of assessed stations seeing winter temperatures rise by at least 1°F. This warming threatens the winter sports economy, which supported over 191,000 jobs and contributed $11.3 billion to the national economy in the 2015-16 season. The report highlights a decline in below-freezing days and divergent snowfall trends, with significant decreases in the Western U.S. and increases in the Great Lakes region. Future projections suggest that unchecked emissions could rob states like Colorado of more than a month of below-freezing days by midcentury.

The Union of Concerned Scientists identifies numerous New Jersey communities facing 'chronic flooding'—defined as high tides flooding 10% or more of usable non-wetland area at least 26 times per year. Under an intermediate scenario, 21 communities will face this by 2035, increasing to over 100 by 2100. Under a high scenario, 73 communities are exposed by 2060 and 131 by 2100, including Newark and Elizabeth. The report argues that reducing global warming could save 28 or more communities by 2060 and 45 to 73 by 2100. Recommended actions include updating flood risk maps, reforming insurance premiums, funding FEMA programs, and implementing population relocation strategies.

The Clean Air Task Force (CATF) has launched the Climate Equity and the Clean Energy Transition Project to address the historical trend of placing clean energy infrastructure in low-income neighborhoods and communities of color, which often exacerbates existing injustices. The project aims to move from adversarial relationships to cooperative engagement between environmental justice communities, the energy sector, and climate advocates. Key activities include on-site community research, analyzing best practices for clean energy siting to protect public health, and developing a roadmap to modernize federal government programs and budgets to make them more accessible to underserved populations. Additionally, CATF is piloting an online capacity-building tool for community engagement and hosting workshops with environmental justice organizations to redefine decision-making processes and address air quality health impacts. The project focuses on various U.S. rural, tribal, and urban locations, including the Navajo Nation and the Ironbound Community, to produce recommendations for equitable project development and federal program implementation.
