The document outlines the technical approaches used to estimate children's exposure to chlorpyrifos and PFAS, the process for tracking children's product recalls, and the use of EPA Regulatory Impact Analyses to quantify the health benefits lost when air pollution standards were weakened or repealed.

The Union of Concerned Scientists projects that without reductions in carbon emissions, US military installations will face a significant increase in days with a heat index above 100°F by midcentury, potentially increasing the rate of heat-related illnesses (HRIs). The report highlights that basic training recruits are particularly vulnerable and that installations in Florida are projected to be among the most affected. To address these risks, the memo recommends increased funding for HRI research, the establishment of an expert working group, improved training on acclimatization, and a transition toward renewable energy to limit future warming.

The report finds that 91% of analyzed coal plants have unsafe levels of coal ash constituents in their groundwater. It highlights systemic failures in the 2015 Coal Ash Rule, such as the exemption of older dumps and inadequate monitoring of 'upgradient' wells. The analysis identifies the ten most contaminated sites in the U.S., noting that many impact low-income communities and communities of color. The authors argue that current regulations are insufficient and recommend regulating all ash dumps, requiring 'high and dry' storage, and increasing transparency and drinking water testing.

The document details the systemic contamination of groundwater by coal ash at 91% of monitored U.S. coal plants, highlighting the toxicity of substances like arsenic and lead. It describes legal actions and community advocacy used to challenge the Trump administration's attempts to weaken the 2015 coal ash rule and discusses the implementation of the Coal Ash Pollution Prevention Act (Senate Bill 9) in Illinois to ensure financial assurance and transparency in cleanups.

The report finds that while global warming is generally ranked lower than immediate issues like terrorism and healthcare, its importance as a voting priority varies significantly by political affiliation and geography. Liberal Democrats rank it as the fourth most important issue, whereas conservative Republicans rank it as the least important of 28 issues. Regional differences are evident, with high priority in states like New York and Hawaii, and lower priority in states like Alabama and West Virginia. However, the broader issue of environmental protection is a higher priority for about half of registered voters.

The document provides a comprehensive overview of the coal industry in the United States, detailing the transition from underground to surface mining and the shift toward low-sulfur coal. It highlights the severe ecological damage caused by mountaintop removal and the public health risks associated with coal combustion, including the emission of sulfur dioxide, mercury, and carbon dioxide. The guide also discusses the economic decline of coal due to the rise of natural gas and renewables, while noting the energy-intensive nature of carbon capture and storage (CCS) technologies.

The document argues that federal light-duty vehicle standards set by the EPA and NHTSA provide significant financial and environmental advantages to Kentucky. It highlights that by 2030, the average Kentucky household will be $3,150 richer due to gas savings, and the state has already saved $540 million. Environmentally, the standards eliminate global warming emissions equivalent to half of those produced by providing electricity to Louisville. The report also links these standards to broader national economic growth, including an expected increase in GDP by up to $30 billion and the creation of 650,000 full-time jobs by 2030.

The report analyzes the challenges facing Shanxi province as it transitions away from coal, highlighting the tension between national environmental goals and provincial economic dependence. It uses international case studies to argue that successful transition requires a comprehensive approach combining economic diversification, infrastructure investment, and social welfare to prevent long-term regional decline.

The report examines the challenges of coal transition in Shanxi, China, where high economic dependence on coal conflicts with national environmental goals. It analyzes international experiences—specifically South Wales (UK), Asturias (Spain), and Kentucky (USA)—to suggest a comprehensive approach that balances economic diversification, infrastructure improvement, and social protection to mitigate unemployment and community decline.

The document analyzes the U.S. home energy financing landscape, distinguishing between traditional lenders (e.g., FHA, Fannie Mae) and nontraditional options (e.g., PACE, on-bill financing). It argues that consumer choice is driven more by the timing of improvements and ease of origination than by interest rates or terms. Key barriers include manual underwriting for traditional products and a lack of standardization and securitization for nontraditional products. The brief recommends automating underwriting for traditional lenders and creating standardized, poolable programs for nontraditional financing to enable scaling.

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.

A coalition of organizations advocates for Kentucky to expand energy-efficiency programs, arguing they are the cheapest method to reduce emissions and lower consumer costs. The authors suggest that adopting specific policies, such as updated building codes and combined heat and power, could meet 43 percent of the state's 2030 Clean Power Plan compliance goal, potentially saving over $1.6 billion and avoiding nearly 13 million tons of carbon dioxide emissions.

The document outlines strategies for US states to ensure that the Clean Power Plan does not disproportionately burden low-income communities and communities of color. It emphasizes the need for 'high impact' engagement, the conduct of formal Environmental Justice (EJ) analyses, and the avoidance of carbon trading mechanisms that may allow power plants to avoid on-site pollution reductions. The guide also advocates for a 'Just Transition' that provides economic development and job training in communities heavily dependent on fossil fuels.

The document analyzes how carbon taxes or cap-and-trade programs affect U.S. households through expenditures, income, and revenue allocation. While carbon pricing can be regressive in terms of energy expenditures—disproportionately affecting low-income households and coal-dependent regions—the authors argue that the overall impact is determined by how the government uses the revenue. By targeting a small portion of revenue (approximately 10-12%) toward low-income households and coal communities, policymakers can offset burdens and ensure these vulnerable groups are not driven deeper into poverty. The brief compares various revenue uses, such as lump-sum rebates, labor tax swaps, and capital tax swaps, concluding that the policy is not inherently regressive and can be designed to be progressive.

The Union of Concerned Scientists proposes a green bank for Michigan, estimating that an initial public investment of $105 million could leverage $3.3 billion in total clean energy investments by 2030. This financial mechanism would support the deployment of 685 MW of solar capacity and reduce annual carbon dioxide emissions by 3.9 million tons, contributing 13% of the emissions reductions required for the state to meet Clean Power Plan targets. The document outlines various financial products the bank could offer, such as credit enhancements and warehousing, and identifies existing Michigan programs that could be integrated into this structure.

The Union of Concerned Scientists analyzes how a hypothetical Pennsylvania green bank, with an initial $135 million capitalization, could leverage $4.2 billion in total investment by 2030. This initiative would support 780 MW of wind and solar capacity, save $375 million annually on electricity bills, and reduce CO2 emissions by 4.8 million tons per year, contributing 11% of the state's required reductions under the Clean Power Plan.

The Union of Concerned Scientists analyzes how a hypothetical Virginia green bank with $90 million in initial capitalization could leverage $2.8 billion in total investment by 2030, significantly reducing carbon emissions and supporting the deployment of 575 MW of wind and solar capacity.

The document is a formal comment letter from a coalition of environmental groups regarding the proposed Stream Protection Rule. The authors argue that the rule fails to adequately protect stream channels from direct damage, particularly in Central Appalachia, and relies on unproven stream restoration techniques. They contend that OSMRE ignored critical factors in its analysis, including the structural decline of coal demand, the net economic drain of mining on the region, and severe public health impacts. The coalition urges the agency to retain the 1983 stream buffer zone, strengthen water quality standards, and incorporate the social cost of carbon into its environmental impact assessments.

The report examines clean energy financing tools used by six U.S. states and Germany to scale up renewable energy and energy efficiency investments. It highlights the role of 'green banks' and other mechanisms in reducing financial risks for the private sector and overcoming barriers like high upfront costs and limited technical understanding among financiers. Case studies include Connecticut and New York's green banks, Pennsylvania and Kentucky's use of the Warehouse for Energy Efficiency Loans (WHEEL), Iowa's revolving loans, and Massachusetts's Mass Save HEAT Loan. The report concludes that these tools can help states achieve Clean Power Plan targets by leveraging limited public funds to attract significant private capital.

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.
