The report analyzes the transition of Illinois's medium- and heavy-duty (M/HD) vehicle fleet to zero-emission vehicles (ZEVs) under three scenarios: the Advanced Clean Trucks (ACT) Rule, the ACT plus NOx Omnibus Rule, and a highly ambitious '100 x 40 ZEV + Clean Grid' scenario. The most aggressive scenario is projected to yield cumulative net societal benefits of over $44.6 billion by 2050, including 878 avoided premature deaths and 995 fewer hospital visits. While ZEVs currently have higher purchase costs, the analysis projects that the average ZEV will reach lifetime cost parity with combustion vehicles by 2030. The transition is expected to have positive macroeconomic effects, including net national job gains and increased GDP by 2035, although these gains depend on the development of U.S.-based component manufacturing. Significant infrastructure investment is required, with the 100 x 40 ZEV scenario requiring an average of $130 million annually for depot charging and $169 million for public charging networks through 2050.

The report analyzes the transition of New Mexico's medium- and heavy-duty (M/HD) vehicle fleet to zero-emission vehicles (ZEVs) under three policy scenarios: the Advanced Clean Trucks (ACT) Rule, the ACT Rule plus NOx Omnibus Rule, and a highly ambitious '100 x 40 ZEV + Clean Grid' scenario. The analysis finds that while ZEVs currently have higher purchase costs, they are projected to reach lifetime cost parity with combustion vehicles by 2030. The most aggressive scenario results in cumulative net societal benefits of over $6.7 billion by 2050, including 65 avoided premature deaths and 59 fewer hospital visits. Macroeconomic modeling suggests the transition would lead to national net job gains and increased GDP by 2035, with new jobs in electrical component manufacturing and infrastructure construction offering wages nearly twice as high as the jobs they replace. However, the report notes that increased electricity demand could potentially raise residential and commercial electricity rates in New Mexico by up to 2% by 2050 without effective utility planning.

The analysis examines the transition of Nevada's medium- and heavy-duty (M/HD) vehicle fleet to zero-emission vehicles (ZEVs) under three scenarios: the California Advanced Clean Trucks (ACT) Rule, the ACT Rule plus the NOx Omnibus Rule, and a highly ambitious '100 x 40 ZEV + Clean Grid' scenario. The most aggressive scenario projects cumulative net societal benefits of over $9.6 billion by 2050, including 98 avoided premature deaths and 71 fewer hospital visits. While ZEVs currently have higher purchase costs, the report finds that average ZEVs in Nevada are projected to reach lifetime cost parity with combustion vehicles by 2030, eventually providing significant fuel and maintenance savings. The transition would reduce petroleum dependence, increase electricity demand, and potentially lower residential and commercial electricity rates due to increased utility net revenue. Macroeconomic modeling suggests national net job gains through 2035, with new jobs in electrical component manufacturing and infrastructure construction offering wages nearly twice as high as the jobs they replace.

The Union of Concerned Scientists and partner organizations provide a guide for science advocates to combat voter suppression and disinformation during the 2022 US elections. The document outlines three primary actions: 'tripling the vote' through peer reminders, running voter registration and vote plan drives using tools like TurboVote and BallotReady.org, and volunteering as poll watchers or workers through the Lawyers Committee on Civil Rights. It emphasizes that protecting democracy is essential for achieving science-based solutions to environmental and public health challenges.

The document is a formal request from a group of scientists and engineers to President Biden, outlining four primary recommendations for the Nuclear Posture Review to reduce the risk of nuclear conflict and fulfill disarmament obligations under the Nuclear Non-proliferation Treaty.

The adoption of the ACT and HDO rules in Massachusetts is projected to significantly reduce toxic air pollutants and carbon emissions from medium- and heavy-duty vehicles, leading to substantial health savings and net societal benefits by 2050.

The adoption of the Advanced Clean Trucks (ACT) and Heavy-Duty Omnibus (HDO) rules in Oregon is projected to significantly reduce toxic air pollutants and greenhouse gas emissions from medium- and heavy-duty (M/HD) vehicles. By 2050, these regulations are expected to reduce NOx emissions by nearly 90% and PM2.5 by over 80%, preventing approximately 156 premature deaths and 118 hospital visits. Economically, the shift is projected to generate $21.2 billion in cumulative net societal benefits by 2050, with electric truck operators seeing an estimated $60,000 in net lifetime savings per vehicle by 2040 due to lower fuel and maintenance costs.

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 document details the impact of Washington adopting the Advanced Clean Trucks (ACT) rule, which requires an increasing percentage of new medium- and heavy-duty (M/HD) vehicle sales to be zero-emissions starting in 2024. It highlights that while M/HD vehicles make up only 10% of vehicles on Washington roads, they contribute disproportionately to pollution, including 30% of global warming emissions, 60% of NOx, and 50% of PM2.5 from on-road vehicles. The transition is projected to eliminate nearly 47 million metric tons of carbon dioxide by 2050 and generate $24.9 billion in cumulative net societal benefits by the same year.

The document challenges the notion that wind curtailment results from an oversupply of wind, using analysis of the Southwest Power Pool (SPP) to show that higher-cost coal plants often remain online while wind is curtailed. It identifies three primary drivers of this waste: inadequate transmission capacity, the practice of coal plants 'self-committing' to avoid being turned off, and a lack of battery storage. The author argues that addressing these infrastructure and operational shortcomings would reduce costs for consumers and lower carbon emissions.

Ethylene oxide (EtO) is a colorless, flammable gas used primarily for sterilizing medical equipment and as a chemical building block. Classified as a carcinogen by the EPA and other bodies, chronic inhalation is linked to white blood cell cancers and breast cancer. The document highlights that EtO emissions disproportionately affect low-income communities and people of color, with some areas in Louisiana experiencing cancer risks over 200 times the EPA's acceptable levels. While the EPA has updated the Miscellaneous Organic Chemical Manufacturing (MON) rule, the document argues that current regulations fail to require fenceline monitoring or a complete phaseout of the chemical, calling for stronger enforcement and the adoption of less toxic alternatives.

The Union of Concerned Scientists documents how the fossil fuel industry in Colorado employs four primary disinformation tactics—The Fix, The Diversion, The Screen, and The Fake—to maintain political control and undermine public health and safety. The report details the industry's use of front groups, lobbying, and misleading economic claims to thwart regulations and ballot initiatives, while highlighting the disproportionate impact of pollution on communities of color and low-income residents. It concludes with recommendations for state regulators to prioritize science and community voices over industry profits.

The report analyzes how Highland Park, Michigan, can transition to 100 percent locally generated clean energy to achieve energy sovereignty. It identifies a total average annual electricity demand of approximately 86,200 MWh and proposes a mix of rooftop solar, community solar, energy efficiency, distributed solar, and a community water and energy resource center (CWERC) to meet this need. The analysis highlights that current utility restrictions and state policies create long payback periods for solar investments, but a proposed policy scenario—including full retail-rate net metering and state tax credits—could increase rooftop solar's contribution from 13 percent to nearly 30 percent of the city's energy needs. The document concludes with recommendations for Michigan policymakers to eliminate distributed generation caps and for Highland Park leaders to enact solar ordinances and establish local financing mechanisms.

The document outlines the use of HOMER Grid software to optimize energy systems in Highland Park, MI, assuming investments made in 2023. It details building stock estimates, electricity rate tariffs from DTE Energy, and the impact of policy incentives like net metering and SRECs on payback periods for residential and commercial solar installations.

The report examines the historical and current trends of coal ash reuse, distinguishing between encapsulated uses (such as concrete and wallboard) and unencapsulated uses (such as mine reclamation and structural fill). While encapsulated reuse can reduce CO2 emissions, unencapsulated reuse is flagged as a high-risk practice that may serve as a loophole for unregulated disposal, potentially contaminating groundwater. The document advocates for the precautionary principle and legal classification of unencapsulated reuse as disposal to protect public health.

The analysis evaluates the economic output, value added, labor income, and employment generated by two different coal ash remediation strategies at two power plants in the Ohio River Valley. Using IMPLAN models, the study finds that 'clean closure' scenarios consistently produce higher economic output and employment than company-proposed plans, with the vast majority of job creation occurring during the initial construction and excavation phases.

The report compares utility-proposed closure plans with 'clean closure' alternatives at two US power stations. It finds that while clean closure—which involves the full excavation of coal ash from unlined ponds—requires higher initial capital investment, it provides superior groundwater protection and creates significantly more direct construction jobs. At the J. M. Stuart station, clean closure would cost $279.3 million and create 277 FTEs, compared to $224.4 million and 223 FTEs for the utility plan. At the Sebree station, clean closure would cost $125.7 million and create 138 FTEs, compared to $65.2 million and 63 FTEs for the utility plan.

The document examines the environmental and health risks of coal ash, one of the largest industrial waste streams in the US, and advocates for 'clean closure' (full remediation and excavation) over limited cleanup plans. Using case studies from the J. M. Stuart plant in Ohio and the Sebree Generating Station in Kentucky, the authors demonstrate that comprehensive cleanup generates significantly more jobs and economic output than utility-proposed plans. The report highlights that coal ash sites disproportionately affect low-income communities and communities of color, particularly in the Ohio River Valley, and recommends stronger EPA enforcement, polluter-pays funding, and the prioritization of dislocated workers in hiring.

The report examines the hazards of coal ash disposal, particularly in the Ohio River Valley, and advocates for 'clean closure' (excavation) over 'cap-in-place' methods. Through case studies of the Sebree Generating Station in Kentucky and the J. M. Stuart Station in Ohio, the authors demonstrate that comprehensive cleanup generates significantly more jobs and economic output than utility-proposed plans. The document highlights the disproportionate impact of coal ash pollution on low-income communities and people of color, and calls for stronger EPA enforcement and state-level regulations to ensure the safe removal of toxic waste.

The document serves as a how-to guide for scientists seeking employment in the US federal government. It highlights a current shortage of federal scientists and provides practical advice on using USAJobs.gov, tailoring resumes and cover letters to meet strict agency requirements, and preparing for civil service interviews. It also emphasizes the importance of federal science in addressing global climate change and protecting underserved communities, noting that 28 agencies have scientific integrity policies to prevent political interference.
