The Union of Concerned Scientists (UCS) reports widespread PFAS contamination at US military bases, with many sites exceeding risk levels established by the Agency for Toxic Substances and Disease Registry (ATSDR). The document highlights the health risks of these 'forever chemicals', the history of industry disinformation, and the failure of the US military to transition to fluorine-free firefighting foams.

The report analyzes how electoral rules—including registration eligibility, voting processes, and districting—impact voter turnout, particularly in environmental justice communities. It finds that socioeconomic distress and poor air quality are significant depressors of turnout, and that states with biased districting plans tend to have higher levels of air toxin exposure. The authors argue that restrictive election laws insulate powerful interests and weaken environmental protections, citing the Flint water crisis as an example of legislative dysfunction resulting from gerrymandering. The document recommends reforms such as automatic voter registration, nonpartisan redistricting, and proportional representation to improve government responsiveness and public health outcomes.

The document details how climate change is increasing the frequency and severity of heat waves in the United States, leading to higher mortality rates and significant disruptions. It highlights the disproportionate vulnerability of children, the elderly, low-income and minority populations, and outdoor workers. Beyond health, extreme heat damages transportation infrastructure, reduces agricultural yields, and strains the electricity grid, necessitating a transition to low-carbon energy solutions and adaptive urban design to mitigate these risks.

The report warns that sea level rise puts hundreds of thousands of US coastal properties at risk of chronic inundation, potentially leading to a collapse in real estate values and a significant erosion of local tax bases. Using a high sea level rise scenario, the analysis projects that by 2100, nearly 2.5 million properties valued at $1.07 trillion today will be at risk. The authors argue that current financial markets and government policies mask these risks, creating a 'narrowing window of opportunity' for communities to adapt. The report highlights particular vulnerabilities for low-income populations, the elderly, and specific states like Florida and New Jersey, while advocating for updated flood maps, transparent risk disclosure, and a shift away from subsidized insurance and disaster aid that encourages rebuilding in high-risk areas.

The report details research and stakeholder discussions regarding the under-utilization of specialty crops in the US. It highlights significant in-field losses—such as 50% for fresh tomatoes and 36% on average for crops in North Carolina—driven by strict cosmetic standards and economic barriers. The document outlines four envisioned future states: implementing full-cost accounting for food, increasing ubiquitous access to healthy produce, integrating regional food systems with industrial agriculture, and removing food safety barriers to donation. It concludes with a practical example of 'concurrent harvesting' used by Imperfect Produce to create markets for 'seconds'.

The report quantifies the health risks faced by millions of African Americans living near oil and gas infrastructure, highlighting elevated cancer risks and asthma attacks. It details the role of systemic oppression in siting polluting facilities in communities of color and calls for stricter EPA regulations and a transition to a clean energy economy.

Federal fuel economy and vehicle emissions standards have saved North Carolina $1.2 billion to date and are projected to make the average household $3,300 richer by 2030. These standards are expected to create 22,500 new jobs in the state and eliminate global warming emissions equivalent to more than those produced by providing electricity to Charlotte.

A coalition of environmental and animal welfare organizations urges the National Marine Fisheries Service (NMFS) to withdraw proposed incidental harassment authorizations (IHAs) for five industrial seismic surveys off the U.S. East Coast. The document argues that NMFS used outdated scientific thresholds to underestimate the 'take' of marine mammals, failed to account for cumulative impacts of multiple surveys, and ignored significant harm to prey species and acoustic habitats. It specifically highlights the risk to the critically endangered North Atlantic right whale, asserting that the proposed activity could be a "tipping point" for the species' survival. The coalition further claims that the proposed mitigation measures, such as seasonal closures and visual monitoring, are insufficient and not based on the best available science.

The Union of Concerned Scientists (UCS) defines 'chronic inundation' as tidal flooding affecting 10% or more of a community's usable land at least 26 times per year. Under a moderate (intermediate) scenario, nearly 170 communities will reach this threshold by 2035, increasing to over 270 by 2060 and nearly 490 by 2100. A high scenario projects up to 670 communities affected by 2100, including over 50 populous cities such as New York City (four boroughs), Boston, and Oakland. The report highlights that socioeconomically vulnerable neighborhoods are disproportionately affected and argues that aggressive emissions reductions aligned with the Paris Agreement could spare hundreds of communities from this fate. Adaptation options include defending (seawalls, levees), accommodating (elevating homes, pumps), and managed retreat.

The Union of Concerned Scientists (UCS) identifies numerous North Carolina communities facing 'chronic inundation'—defined as high tide flooding 10% or more of usable, non-wetland area at least 26 times per year—by 2035 and 2100. Under an intermediate scenario, 13 communities will face this by 2035 and 36 by 2100; under a high scenario, 43 will be affected by 2060 and 63 by 2100. The report emphasizes that curtailing warming could spare between 23 and 37 communities from chronic inundation by the end of the century. Recommended actions include updating flood risk maps, reforming insurance, enhancing FEMA funding, and creating programs for managed retreat and relocation.

The report finds that Americans are more likely to engage in consumer activism than political activism to address global warming, though many underestimate its effectiveness. While consumers often rely on individual purchasing decisions, the text argues that public communication and bad publicity are more effective at changing corporate practices than sales decreases alone.

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.

The Cape Hatteras Lighthouse in North Carolina was moved inland in 1999 to prevent it from being lost to the sea due to coastal erosion and sea level rise. The structure, weighing over 4,800 tons, had seen its distance from the ocean shrink from 1,500 feet at construction to 120 feet by the end of the twentieth century. This relocation serves as an example of the 'hard choices' required to protect historic sites as sea levels in the Outer Banks rise two to three times faster than the global average and Category 4 and 5 hurricanes in the North Atlantic have roughly doubled since 1970.

The briefing provides a historical analysis of nuclear waste siting in the United States, asserting that the Department of Energy (DOE) has consistently failed to secure long-term consent for high-level waste (HLW) and spent nuclear fuel (SNF) repositories. The author highlights a pattern of broken promises, litigation, and the failure of both the Nuclear Waste Policy Act (NWPA) and the 'volunteer' process managed by the Nuclear Waste Negotiator. Key examples include the legal battles over the Waste Isolation Pilot Plant (WIPP) and the non-consent of the Nevada state government regarding Yucca Mountain. The document concludes that the DOE's lack of reliability makes it unlikely that future consent agreements for consolidated storage or repositories will be trusted or successful.

A coalition of organizations wrote to Governor Patrick McCrory of North Carolina advocating for the expansion of energy efficiency programs as the most cost-effective way to comply with the Clean Power Plan. The letter argues that efficiency measures—including updated building codes and combined heat and power—could meet 56 percent of the state's 2030 compliance goal, saving residents $652 million and avoiding 8.9 million tons of carbon dioxide emissions.

The Union of Concerned Scientists proposes a "Clean Path" for Virginia to comply with the Clean Power Plan by transitioning from voluntary to mandatory renewable energy and energy efficiency targets and implementing a mass-based carbon emissions-trading program. The analysis suggests this approach would reduce CO2 emissions by 77 million tons through 2030 compared to a reference case, lower typical residential electricity bills by 5% by 2030, and generate an average of $241 million in annual auction revenue for state investments. The report highlights Virginia's current underutilization of its renewable potential, noting that non-hydro renewables accounted for only 2.8% of electricity generation in 2014.

The document provides a comprehensive overview of offshore wind energy as of early 2016, contrasting the advanced capacity in Europe with the nascent industry in the United States. It details the technical advantages of offshore wind over onshore wind, such as stronger and more consistent winds and proximity to coastal population centers. The text outlines U.S. government initiatives, including Department of Energy funding and Bureau of Ocean Energy Management leasing, while highlighting the United Kingdom, Germany, and Denmark as global leaders. It also discusses the economic impact of the sector, specifically the 'additional employment effect' in European ports and shipyards.

The report examines 13 watershed investment programs in the U.S., focusing on how natural infrastructure—specifically forests—can be used to protect drinking water quality and quantity. It provides a framework for program development across three phases: building momentum, designing the program, and implementing the action plan. Key findings emphasize the importance of collaborative partnerships, scientifically informed planning, and diverse financing mechanisms, such as municipal bonds and water rate surcharges, to overcome barriers like insufficient funding and lack of outcome data.

Fuel cells generate electricity through a chemical reaction between oxygen and hydrogen, offering a high-efficiency, low-emission alternative to combustion engines and batteries. While they excel in reliability, scalability, and energy density, widespread adoption is hindered by high costs—particularly the need for platinum in PEM cells—and the lack of hydrogen fueling infrastructure. Applications range from portable electronics and stationary power (including combined heat and power systems) to transportation. In the U.S., the Department of Energy and various state-level policies, such as Renewable Portfolio Standards and tax credits, are working to reduce system costs and expand infrastructure to make fuel cells more competitive with gasoline-powered vehicles.

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.
