The document details how oil and gas emissions, including ozone smog and toxic air pollutants, cause asthma attacks in children and restricted activity in adults across Indiana, while highlighting the proximity of schools and residents to active oil and gas sites.

The document details how oil and gas emissions, including ozone smog from across the central and western US and local toxic pollutants, cause significant health issues in Ohio. It highlights that nearly 30,000 children in Ohio suffer annual asthma attacks due to industry-linked ozone, with high concentrations in the Cleveland-Akron, Columbus, and Cincinnati areas. Additionally, it notes that over 160 tons of hazardous toxic air pollutants were emitted from more than 90,000 sites in Ohio in 2011, and over 2,500 schools are located within a half-mile of these operations.

The report details how the US oil and gas industry emits methane, toxic air pollutants (such as benzene, formaldehyde, and acetaldehyde), and ozone precursors that cause cancer and respiratory illnesses. It provides state-specific data for Arizona, Colorado, Indiana, North Dakota, Ohio, Pennsylvania, South Carolina, Tennessee, Texas, and West Virginia, highlighting that ozone pollution travels across state borders, affecting residents even in states with little to no local industry activity. The document emphasizes the vulnerability of children and low-income communities and argues for the necessity of strong federal standards from the EPA and the Bureau of Land Management to protect public health.

The document reports significant job growth in the U.S. clean energy sector as of early 2016. It highlights that solar and wind industries are expanding rapidly, with solar jobs growing 17 times faster than the overall economy and wind-turbine technicians projected as the fastest-growing occupation. Energy efficiency employs the largest volume of workers at 2.2 million. Geographically, Texas leads in wind jobs, while California leads in solar and energy efficiency jobs.

Agricultural runoff of nitrogen and phosphorus is a primary driver of water contamination and eutrophication in the U.S., particularly affecting the Great Lakes and the Gulf of Mexico. While the Clean Water Act does not regulate water leaving farmers' fields, various state-level initiatives and federal programs, such as the USDA's Regional Conservation Partnership Program (RCPP), promote voluntary best management practices to reduce nutrient loading. Climate change is expected to worsen these issues by increasing the frequency of extreme weather events that trigger higher runoff.

The Union of Concerned Scientists argues that US farm and food policies are uncoordinated and often work at cross-purposes, leading to economic stagnation in rural areas, environmental degradation, and high public health costs. The brief urges the Trump administration to realign these policies to ensure access to healthy, sustainably produced food while supporting the livelihoods of farmers and food system workers.

The briefing explains that measuring electricity emissions through average factors often misrepresents the actual environmental impact of energy use. By adopting technology that tracks marginal emissions—the rate at which emissions change with a small change in load—consumers and corporations can optimize the timing and location of electricity use to maximize carbon reductions. The author highlights that harnessing end-use flexibility can make devices run 15 percent cleaner on average without cost or quality impacts. Practical applications include timing electric vehicle charging to avoid peaking plants and valuing renewable energy projects based on their specific carbon reduction potential rather than treating all megawatt-hours as equal.

Agricultural runoff of nitrogen and phosphorus is a primary driver of water contamination, leading to eutrophication and hypoxic zones in the Gulf of Mexico and Great Lakes. Climate change is expected to worsen this by increasing the frequency of heavy rains and subsequent nutrient runoff. While the Clean Water Act does not regulate water leaving farmers' fields, various state-level voluntary and mandatory programs, alongside the federal Regional Conservation Partnership Program (RCPP), aim to reduce nutrient loading through best management practices like cover crops and no-till operations.

The paper examines the adoption of Biodiversity Offsetting in England, highlighting a significant gap between policy implementation and research on its impacts. Through stakeholder interviews, the authors identify critical failures in both ecological compensation—such as the oversimplification of biodiversity metrics—and social compensation, specifically the marginalization of local communities and the loss of public access to nature. The study argues that the current 'no net loss' framework is a normative construct that often fails to account for the irreplaceable nature of certain habitats and the distributive justice concerns of affected populations.

The report finds that millions of Latinos in the US are disproportionately exposed to toxic air pollutants and ozone from oil and gas infrastructure, leading to significant health burdens. It highlights that 1.81 million Latinos live within a half-mile of such facilities and 1.78 million live in counties where cancer risks exceed EPA concern levels. The document argues that poverty and lack of health insurance exacerbate these risks, and calls for the EPA to regulate existing facilities, not just new ones, to protect public health and address climate change.

The report finds that millions of Latinos are exposed to toxic air pollutants and ozone smog from oil and gas facilities, leading to elevated cancer risks and childhood asthma attacks. These health threats are exacerbated by higher poverty rates and lower health insurance coverage within Latino populations. The authors argue for comprehensive EPA regulations covering both new and existing oil and gas infrastructure to reduce methane and toxic emissions.

The report estimates that oil and gas emissions will cause over 750,000 summertime asthma attacks in children under 18 across the U.S. in 2025. It identifies volatile organic compounds (VOCs) and nitrogen oxides (NOx) as the primary precursors to this ozone smog, noting that pollution travels far downwind to affect all 48 contiguous states. The analysis highlights Texas, Oklahoma, Colorado, and Pennsylvania as states with the highest number of asthma attacks. To mitigate these effects, the report recommends implementing leak detection and repair (LDAR) programs, replacing high-emitting pneumatic equipment, and using vapor recovery units on storage tanks.

The document traces the evolution of octane sources in the U.S., from the use of tetraethyl lead to petroleum-based aromatics (BTEX) and ethanol. It details the health risks associated with lead and BTEX, the regulatory phase-outs mandated by the EPA under the Clean Air Act, and the potential for mid-level ethanol blends (E25 to E40) to enable more fuel-efficient engines and lower greenhouse gas emissions.

The document traces the evolution of octane boosters in the United States, from the early use of tetraethyl lead to the current reliance on the BTEX complex and ethanol. It details how health concerns—such as lead poisoning in children and groundwater contamination from MTBE—led to regulatory phase-outs under the Clean Air Act and its amendments. The author argues that increasing ethanol blends (specifically mid-level blends between E25 and E40) can enhance engine efficiency, lower greenhouse gas emissions, and reduce the health risks associated with petroleum-based aromatics.

Five years after the Fukushima disaster, the Union of Concerned Scientists argues that the US Nuclear Regulatory Commission (NRC) has failed to implement critical safety upgrades, often favoring industry-led voluntary initiatives over enforceable regulations. The report highlights significant gaps in the 'FLEX' emergency equipment program, the rejection of a comprehensive new regulatory framework, and the failure to mandate filtered containment vents or expedited spent fuel transfer, leaving US nuclear plants vulnerable to beyond-design-basis events.

The Union of Concerned Scientists (UCS) analysis finds that two-thirds of U.S. states may be exposing electricity consumers to financial risks due to overreliance on natural gas. These risks include price volatility, potential carbon pricing costs, and the possibility of stranded assets such as underused plants and pipelines. The report rates states across five categories, identifying Florida as the only state with a "High" risk rating in all five. To mitigate these risks, the report advocates for prioritizing renewable energy and energy efficiency over natural gas as a primary solution for carbon reduction under the federal Clean Power Plan.

The report outlines a toolkit for local governments to manage the rapid expansion of unconventional oil and gas development, such as hydraulic fracturing. It details regulatory options like zoning and setbacks, non-regulatory strategies including community engagement and contractual agreements, and fiscal tools such as severance taxes and road maintenance agreements. The document emphasizes the challenge of state-level preemption and the need for local officials to act as 'honest brokers' between industry and concerned residents.

A coalition of 290 organizations and individuals opposes H.R. 1734, asserting that the bill would weaken the U.S. Environmental Protection Agency's (EPA) 2014 coal ash rule. The signatories argue the legislation would delay health protections, eliminate public access to information, and remove national standards for drinking water protection, thereby increasing risks to vulnerable communities and the environment.

The document contrasts a 1995 ALEC claim that global warming predictions were theoretical and lacked scientific consensus with the 1995 IPCC Assessment Report, which identified a "discernible human influence on global climate." It details ALEC's role in distributing "model" legislation to state legislators to oppose EPA carbon standards and repeal renewable energy standards, noting that ALEC's Energy, Environment, and Agriculture Task Force has included members such as BP, Chevron, ExxonMobil, Peabody Energy, and Shell.

The document contrasts scientific consensus on anthropogenic climate change with the activities of the American Legislative Exchange Council (ALEC). It asserts that ALEC, funded by fossil fuel interests, promotes misinformation to state legislators to block EPA regulations and repeal renewable energy standards.
