As of August 2021, fewer than 1% of U.S. school buses are electric, with adoption heavily concentrated in California and suburban areas. While 33 states have committed to electric buses, the report emphasizes that targeted public funding is essential to ensure these benefits reach vulnerable communities and rural areas, which currently lag in deployment despite the health risks posed by diesel emissions to students.

As of December 2021, 1,828 electric school buses were committed across 36 US states, representing a 57% increase since June 2021. California is the primary leader in adoption, holding nearly half of all commitments. While adoption correlates with high median household income, it is more evenly distributed across different poverty levels. The report notes that the vast majority of the US school bus fleet (95%) still relies on diesel, and that the Infrastructure Investment and Jobs Act has allocated $5 billion over five years to accelerate the transition to lower-emission buses.

Phosmet is a U.S. registered pesticide used in 40 states, primarily on orchards and grapes, and is currently under registration review. It is associated with serious health effects, including cancer, neurodevelopmental harm, and reproductive toxicity, with exposure occurring via food, drinking water, and occupational contact. The pesticide is applied to a significant percentage of several common crops, including peaches (55%) and nectarines (50%).

The document contends that continued investment in US gas distribution infrastructure is counterproductive to climate goals, as the transition to electric appliances will likely leave these systems underutilized. It argues that low-carbon gases like hydrogen and biomethane are too expensive for residential and commercial use and should be reserved for industrial applications. Furthermore, it suggests that electrification and targeted leak detection are more cost-effective ways to reduce methane emissions than massive pipeline replacement programs, which risk creating stranded assets and imposing high costs on consumers.

ClientEarth argues that Ofgem's current statutory objectives are outdated and prioritize competition over decarbonisation, hindering long-term climate investments. The submission proposes narrowing Ofgem's principal objective to focus on security of supply and greenhouse gas reduction, introducing sector-specific carbon budgets, and requiring the Department for Business, Energy and Industrial Strategy (BEIS) to issue periodic Strategy and Policy Statements. Additionally, ClientEarth highlights a failure to regulate and verify non-carbon dioxide emissions, specifically methane and sulphur hexafluoride (SF6), and advocates for a consumption-based emissions accounting approach to include extraterritorial emissions from imported energy.

The report analyzes the role of hydrogen in the energy transition, contrasting 'green hydrogen' (produced via renewable-powered electrolysis) with the current industry standard of steam methane reformation (SMR) from fossil fuels. It warns that the oil and gas industry uses hydrogen rhetoric to justify continued fossil fuel infrastructure and delay electrification. The authors argue that green hydrogen should be reserved for 'hard-to-electrify' sectors like maritime shipping and high-heat industrial processes, while being rejected for use in passenger vehicles, home appliances, and gas-fired power plants due to energy inefficiency, high costs, and pollution risks.

The report examines the rise of Dental Services Organizations (DSOs) in the United States, noting that 27 of the top 30 DSOs are owned by private equity firms. It argues that the private equity model, which seeks high returns over short horizons, creates perverse incentives leading to overtreatment, Medicaid fraud, and deceptive marketing. Through case studies of Aspen Dental, Benevis, and North American Dental Group, the document illustrates how revenue targets can lead to medically unnecessary procedures, such as root canals on infants, and highlights a lack of regulatory oversight in the industry.

The document argues that substituting portland cement with SCMs—such as fly ash, ground glass, natural pozzolans, and blast furnace slag—is a cost-effective way to reduce the embodied carbon of concrete. It highlights that up to 40% substitution is possible in the US, potentially saving 27 Mt CO2e per year and reducing emissions for specific applications by up to 80%. However, it notes that supply for some SCMs is geographically constrained or declining due to the phase-out of coal power, suggesting the reclamation of stored fly ash and the use of natural pozzolans as viable future alternatives.

The text highlights the human costs of plastic pollution, noting that production and incineration facilities are often sited in marginalized communities without adequate consultation. It links plastic production to respiratory and immune system health issues and climate change, while calling for extended producer responsibility and federal legislation to protect vulnerable populations.

Fossil-fuel burning appliances in the US contribute significantly to outdoor and indoor air pollution, climate change, and public health disparities. Gas appliances are particularly problematic, emitting more than twice as much NOX as gas power plants. RMI proposes that the EPA implement a NOX standard of performance under Clean Air Act Section 111(b), requiring all new appliances to be electric by 2030. This transition could avoid over 500,000 tons of NOX and 14,400 tons of PM2.5 annually by 2045, potentially saving over 3,750 lives per year and providing $21 billion in annual economic benefits. The document emphasizes that electric appliances are cost-effective and that policies should include incentives to ensure low-income consumers can access these technologies.

The North American GSS debt market reached USD 311bn by Q1 2021, dominated by the US and primarily driven by green-labelled instruments. While the US is the largest single-country source of GSS debt, the market is heavily concentrated in agency mortgage-backed securities (MBS) and municipal bonds, with limited participation from the real economy's heavy-emitting sectors. Canada's market is smaller but characterized by larger average deal sizes and a strong focus on hydropower. Both nations are seeing a shift toward more ambitious climate targets and enhanced disclosure requirements, though the US lags in post-issuance reporting quality compared to Canada.

The document outlines a comprehensive modeling framework designed to assess the impact of three policy scenarios—the California Advanced Clean Truck (ACT) Rule, the NOx Omnibus Rule, and a '100 x 40 ZEV + Clean Grid' scenario—on the U.S. medium- and heavy-duty (M/HD) vehicle fleet. The framework integrates five analyses: fuel use and emissions, health impacts, economic and jobs effects, utility impacts, and infrastructure gaps. It utilizes tools such as the STate Emission Pathways (STEP) Tool, EPA's MOVES3 and COBRA, and IMPLAN software to quantify changes in greenhouse gases, criteria pollutants (NOx and PM), and macroeconomic metrics like GDP and employment. The report details specific assumptions regarding battery cost trajectories, charging infrastructure requirements, and the social cost of greenhouse gases to ensure a standardized approach for subsequent state-specific reports.

The document examines the technological, economic, and environmental aspects of transitioning the U.S. transportation sector to electric vehicles. It highlights the role of falling battery costs, the necessity of expanding charging infrastructure, and the potential for significant public health improvements, particularly in marginalized communities. It also addresses challenges related to the sourcing of critical minerals like lithium and cobalt and the impact of regional climates on vehicle range.

The U.S. experienced significant growth in wind electricity generation between 2000 and 2020, with wind turbines accounting for 8.4% of total utility-scale electricity generation. Research from Net Zero America's 'High Electrification (E+)' scenario suggests that by 2050, Texas could lead the country with over 180 gigawatts of installed capacity, while Missouri, Iowa, Illinois, and Nebraska could each exceed 100 gigawatts. Offshore wind potential is particularly high along the East Coast, with Environment America estimating a potential for over 7,200 terawatt-hours of electricity per year. The document also highlights job growth potential, noting that Texas could support over 130,000 wind energy jobs by 2050, and rural states like Wyoming, Nebraska, Montana, and Iowa could see more than 200 jobs per 10,000 residents.

The report estimates that retiring four nuclear plants in Illinois would lead to 1,200 to 2,700 premature deaths and $10 to $24 billion in monetized damages over ten years. Retiring two plants (Byron and Dresden) would result in 500 to 1,100 premature deaths and $4.4 to $10 billion in damages over the same period. These impacts are driven by increased PM2.5 emissions from fossil fuel plants used to offset the loss of zero-emission generation.

The document details how the Huntley Alliance, a coalition of labor, environmental, and community groups, responded to the closure of the Huntley Generating Station in Tonawanda, New York. It highlights the successful lobbying for the Electric Generation Facility Cessation Mitigation Fund to offset tax losses and the development of the 'Tonawanda Tomorrow' economic action plan to diversify the local economy and redevelop waterfront property.

The document argues that U.S. nuclear policy is currently operating in an "information vacuum," with the Nuclear Regulatory Commission (NRC) often prioritizing licensee cost-savings over public safety and environmental data. It highlights systemic risks in "fast-track" decommissioning, the vulnerability of thin-walled spent fuel canisters to corrosion and failure, and the lack of scientific evidence supporting 80-year license extensions for aging plants. The authors further caution against the deployment of small modular reactors (SMRs) and the establishment of consolidated interim storage facilities (CISFs) without comprehensive risk and cost analyses. The briefing concludes with ten recommendations to policymakers, including mandating ASME N3 standards for waste containers, requiring "hot cells" for repackaging damaged fuel, and reforming NRC oversight to reduce regulatory capture.

The document reports that infrastructure is responsible for 9-17% of tropical and subtropical deforestation, while mining contributes to approximately 7% of global forest loss. Data from CDP's forest module indicates that while many regional governments have forest policies, there is a lack of operational management plans and risk assessments. The most frequently reported impact of mining and infrastructure-related forest loss is increased greenhouse gas emissions, which governments attempt to manage through integrated land-use planning, afforestation, and policy enforcement. Case studies highlight the Piura Region in Peru, where mining has driven deforestation and indigenous displacement, and New York State, where infrastructure and agriculture are primary drivers of forest loss.

The briefing outlines a strategy for the U.S. federal government to support fossil fuel workers facing displacement due to the energy transition and the economic impact of COVID-19. It proposes three immediate federal interventions: employing workers to rehabilitate abandoned coal mines and plug orphan oil and gas wells, expanding funding for existing economic development programs like the POWER Initiative and the EDA ACC program, and utilizing innovative financial mechanisms such as securitization to lower costs for ratepayers and fund community support. For long-term stability, the author advocates for a comprehensive federal energy transition adjustment assistance program modeled after the Department of Labor's Trade Adjustment Assistance, providing retraining, relocation allowances, and wage insurance.

New York City is ranked first among U.S. cities for the most affordable housing at risk by 2050, with projected annual risk increasing by 248% to 4,774 units. New York State's affordable housing stock is the second most vulnerable in the nation, with 5,293 units projected to be at risk by 2050, representing a 236% increase from current levels.
