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 paper evaluates Detroit's first-of-its-kind Community Benefits Ordinance (CBO), which requires developers of projects valued at $75 million or more receiving significant city subsidies to negotiate benefits with local communities. While the CBO has provided communities a 'seat at the table,' the authors identify significant flaws in the selection of Neighborhood Advisory Councils (NACs), insufficient resources for community negotiators, and weak enforcement of agreements. The report recommends lowering the investment threshold to trigger the CBO, increasing community-elected NAC membership, and adopting environmental justice frameworks to ensure a just energy transition.

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 report identifies seven key vulnerabilities—health disparities, poverty, low educational attainment, poor infrastructure, housing insecurity, environmental harm, and lack of political voice—that characterize disenfranchised U.S. communities. It highlights how these factors compound, particularly for 'doubly vulnerable' populations, and argues that historical exploitation has created a legacy of mistrust that can hinder clean energy projects. The document also critiques current environmental justice screening tools for failing to account for cumulative risks and warns that energy transitions can inadvertently create new underserved communities if not managed equitably.

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 World Resources Institute analyzes CEJST 1.0, finding that while it identifies more disadvantaged populations than the beta version, it lacks a mechanism to prioritize communities facing multiple overlapping burdens. The analysis reveals that non-white populations are disproportionately exposed to higher cumulative burdens, yet the tool treats all disadvantaged communities as equal for funding purposes. The authors recommend incorporating cumulative burden metrics, adjusting low-income eligibility for severely burdened areas, and establishing a rigorous monitoring framework for the Justice40 Initiative.

The report argues that US democracy is in peril due to election subversion, restrictive laws, and a dysfunctional party system. It advocates for a bottom-up approach to reform, emphasizing the role of local community organizations in relational organizing to engage underrepresented voters. Key recommendations include securing election integrity through data transparency, reducing voter suppression via institutional reforms like universal vote-by-mail, and expanding representation by increasing the size of legislative assemblies and adopting more proportional electoral systems.

Earthjustice has developed the Better Lead Policy toolkit to shift the approach to lead poisoning from reacting to blood tests to proactive primary prevention. The toolkit includes a Policy Generator for rental inspection programs, a Cheat Sheet for program elements, and a Deep Dive section featuring examples from over two dozen communities. The document highlights the disproportionate impact of lead poisoning on Black and Latinx children and cites the success of prevention programs in Rochester, New York, and Cleveland.

District energy systems provide centralized heating and cooling to multiple buildings via underground pipes, utilizing sources such as combined heat and power (CHP) plants, waste heat, and renewables. In the United States, over 700 such systems exist, offering benefits like reduced fuel consumption, lower peak electrical demand, and decreased greenhouse gas emissions. While high upfront infrastructure costs can be a barrier, examples from universities and city centers demonstrate significant energy savings and carbon reductions.

The Clean Air Task Force (CATF) supports the EPA's proposed Transport Rule to replace the judicially invalidated Clean Air Interstate Rule (CAIR) but argues it should be strengthened to further reduce sulfur dioxide (SO2) and nitrogen oxides (NOx). CATF specifically advocates for the passage of S. 2995, the Clean Air Act Amendments of 2010 (CAAA of 2010), asserting it would deliver greater emissions reductions, save more lives, and provide more regulatory certainty than the Transport Rule alone. The testimony details the severe health and environmental impacts of power plant emissions, including premature death from fine particulate matter, acid rain damage to eastern ecosystems, and ozone-related crop losses.

The report projects that Ohio will face significantly hotter summers, increased flooding, and agricultural disruptions if current emissions trends continue. It highlights severe risks to public health from heat waves and ozone pollution, and warns of crop and livestock stress. The document advocates for a transition to clean energy through stronger renewable electricity standards, updated building codes, and federal cap-and-trade legislation.

The Clean Air Task Force argues that the EPA's proposed particulate matter (PM2.5) standards fail to provide an adequate margin of safety, potentially resulting in 10,000 more avoidable deaths per year than a more stringent 12 ug/m3 annual standard. The testimony asserts that protective standards are achievable through affordable technologies, specifically targeting sulfur dioxide (SO2) from power plants and carbon emissions from diesel fleets. It criticizes the Clean Air Interstate Rule (CAIR) for providing reductions that are "too little, too late" and for creating regulatory barriers that discourage states from pursuing additional cost-effective power plant reductions. The document advocates for a national SO2 cap of 2 million tons per year and the full funding of the Diesel Emission Reduction Act of 2005 to facilitate the retrofit of existing diesel engines.

The report outlines a comprehensive approach to revitalizing the Cuyahoga Valley by treating environmental restoration as an economic driver. It proposes specific interventions for the 5.5-mile ship channel, including the implementation of low-impact development (LID) for stormwater, the creation of aquatic habitats like pocket wetlands and green bulkheads, and the establishment of an industrial symbiosis network called 'Waste = Revenue'. The document argues that moving away from traditional 'gray' infrastructure toward 'green' solutions will improve water quality, attract investment, and create new local business opportunities in restoration services.

The document examines the intersection of land use and energy efficiency, proposing a framework based on 'how' and 'where' we build to reduce fossil fuel dependence. It advocates for 'energy smart' growth, which combines compact, mixed-use development with green building standards and renewable energy. The author provides recommendations for funders to support this merger through research, integrated planning tools, policy incentives, and innovative financing like location-efficient mortgages.

The document analyzes the carbon footprint of a typical American single-family home, which it estimates emits 26,028 lbs of CO2 annually. It proposes a tiered strategy of no-cost, low-cost, and long-term investments—such as improving the building envelope, upgrading appliances, and purchasing green power—to reduce these emissions. The author argues that a combination of efficiency retrofits, solar water heating, and carbon offsets can lead a household to net zero emissions, potentially reducing emissions by 68% before applying offsets.

The report proposes a comprehensive regeneration strategy for the Cuyahoga River Valley, centering on a 'Regenerative Development Zone' to pilot sustainable business and ecological practices. Key recommendations include implementing industrial symbiosis to redefine waste as a resource, restoring watercourses through 'daylighting' buried streams, adopting green building standards, and diversifying the energy mix with renewables and cogeneration. The authors argue that a whole-system approach—integrating water, energy, and industrial processes—will create synergistic economic and environmental value, transforming the region into a global model for industrial brownfield restoration.

The report identifies energy efficiency as the most cost-effective strategy for cutting U.S. carbon emissions, focusing on the industrial and building sectors which together account for two-thirds of U.S. carbon emissions. It details technical opportunities such as combined-heat-and-power (CHP) systems, building envelope improvements, and high-efficiency appliances. The document proposes a 'Blueprint' of policies—including efficiency standards, resource standards (EERS), and updated building codes—that could reduce total U.S. energy consumption by 29 percent by 2030. It highlights that while technical potential is high, barriers such as 'split incentives' and high up-front costs persist, requiring coordinated federal and state intervention.

The report projects substantial warming and shifting precipitation patterns for the US Midwest, with extreme heat events and heavy rainfall becoming more frequent. Under a higher emissions scenario, end-of-century temperatures could rise by up to 10°F, significantly increasing the frequency of severe heat waves and reducing snow cover. While annual precipitation may only increase slightly, winter and spring are expected to become wetter, while summer precipitation may decrease under higher emissions. These changes are projected to increase heat-related mortality and flooding risks across the region.
