The Union of Concerned Scientists (UCS) finds that over one-third of US nuclear plants are unprofitable or scheduled to close due to cheap natural gas and falling renewable costs. Without carbon-reduction policies, early retirements could increase US power sector emissions by 4% to 6% by 2035. The report recommends adopting carbon pricing or low-carbon electricity standards and conditioning any nuclear subsidies on strict safety performance and consumer protections.

The document argues that Northeast and Mid-Atlantic states can significantly reduce CO2 pollution and consumer fuel spending by transitioning to electric vehicles and low-carbon fuels. It highlights specific targets for emissions cuts and emphasizes the need for equitable investments that prioritize polluted communities and marginalized populations.

The document consists of a series of data tables (Appendix F) detailing the financial and environmental impacts of transportation decarbonization across several US states. It tracks costs such as incremental vehicle costs and charging infrastructure against benefits like gasoline and diesel fuel savings, as well as monetized greenhouse gas (GHG), NOx, and PM2.5 reductions. The data is split between 'MID' and 'HIGH' scenarios for each state, projecting outcomes through 2050.

Climate Central analyzed temperature data from 244 U.S. cities to determine the increase in days falling within the 61-93°F range suitable for disease transmission by Aedes and Culex mosquitoes. The analysis found that 94% of these cities are experiencing an increase in these 'disease danger days' since 1970, with significant increases noted in California, the Southwest, and some northern cities. While most areas face higher risks, some locations like Phoenix may become too hot for mosquito survival. The report also highlights that warmer temperatures shorten the Extrinsic Incubation Period (EIP) of viruses, potentially increasing the number of infectious mosquitoes and expanding the range of species like Aedes albopictus.

The research note analyzes a U.S. Department of Energy proposal to subsidize uneconomic power plants to maintain grid reliability. It estimates that keeping six FirstEnergy coal and nuclear plants online for two years would cost approximately $2 billion. The author contends that these funds would be better spent on locally-led economic diversification and workforce development, noting that grid operators and reliability bodies do not believe such interventions are necessary for stability. The document suggests that redirecting these funds could provide over $300 million per affected community to support a just transition.

The oil and gas industry emits over 8 million tons of methane and toxic pollutants annually, contributing to ozone smog and respiratory issues in rural America. Case studies in Texas, Utah, Pennsylvania, Ohio, and New Mexico highlight increased rates of asthma, cancer risks, and other respiratory ailments among residents living near facilities. The report advocates for federal standards to reduce methane emissions by half through leak detection, reduced venting, and gas capture.

The Union of Concerned Scientists proposes a transportation-based cap-and-invest program for New York State, citing the success of the Regional Greenhouse Gas Initiative (RGGI) in the power sector. The document highlights that transportation is the largest source of emissions in New York and a major cause of health issues in New York City. It suggests that such a program could raise over $1.2 billion annually to fund electric vehicle infrastructure, public transit, and climate resilience.

The Clean Air Task Force welcomes Pennsylvania's action to reduce methane emissions from new natural gas equipment, noting the state's position as the second-largest gas producer. The organization advocates for the state to next address emissions from existing equipment and contrasts Pennsylvania's approach with the federal government's policies, which it describes as rolling back safeguards intended to control methane waste and address climate change.

The document examines how a warming atmosphere increases the frequency and intensity of extreme precipitation, contributing to higher inland flood risks in parts of the United States, particularly the Midwest and Northeast. It highlights that while climate change is a driver, land-use changes—such as development in floodplains and the removal of wetlands—significantly exacerbate flood risk. The report argues that current FEMA flood maps are inadequate because they rely on historical data rather than future projections. To mitigate these risks, the authors recommend reforming the National Flood Insurance Program, increasing funding for river gauge networks and flood mapping, and implementing nature-based infrastructure and stricter zoning regulations to discourage floodplain development.

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 concludes that the proposed Thabametsi Power Plant's coal ash dump is unsuitable and its mitigation measures are insufficient. Key concerns include the siting of the dump atop fault zones, which could facilitate rapid contaminant transport and hinder monitoring, and a groundwater monitoring program that omits numerous critical trace elements. The author also notes significant discrepancies in the applicant's estimated coal combustion residue (CCR) production and argues that the proposed liner system may not meet accepted safety standards, increasing the risk of hazardous waste leaking into water resources used by local populations.

Lone Star Funds acquired DFC Global Corp in 2014, a company operating as a payday lender, pawnshop operator, and check-cashing provider. DFC has faced significant regulatory actions, including a CFPB order to refund $3.3 million to US military servicemembers due to deceptive auto loan practices and a UK Financial Conduct Authority order to refund £15.4 million to customers for unaffordable lending and poor debt collection. The company charges extremely high Annual Percentage Rates (APRs), ranging from 214% in California to 33,465% in Poland, and has actively lobbied against interest rate caps in Hawaii.

The report examines the transition from traditional gray infrastructure to green infrastructure (GI) for stormwater management. It argues that because the benefits of GI are collective while costs are private, public intervention via economic instruments—specifically stormwater markets—is necessary to bridge the investment gap. The document details various price-based and quantity-based instruments, such as stormwater retention credits and environmental impact bonds, and analyzes their application in cities like Washington D.C., Philadelphia, and Halifax.

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.

The brief, submitted by Earthjustice on behalf of community members, contends that medical monitoring is essential for detecting and treating health effects linked to PFC exposure, such as various cancers and autoimmune issues. It argues that the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) does not bar private state-law claims for medical monitoring against potentially responsible parties, even while a federal clean-up is ongoing. The document highlights the severe health impacts suffered by residents near the Naval Air Station Joint Reserve Base Willow Grove and the Naval Air Warfare Center Warminster, and asserts that the District Court erred in applying CERCLA's 'Timing of Review' provision to block these health-related claims.

The document argues that federal light-duty vehicle standards set by the EPA and NHTSA provide significant financial and environmental benefits to Pennsylvania, including $1.2 billion in savings to date and the projected creation of 26,400 new jobs by 2030.

Goldman Sachs became the first U.S. bank to sign a large-scale, off-site renewable energy PPA for a 68 MW wind project in Pennsylvania. The bank utilized a virtual PPA structure within the PJM grid to align clean energy generation with its U.S. consumption while managing commodity risks through its J. Aron business. This deal supports the firm's goal of 100 percent renewable electricity by 2020 and a target of $150 billion in clean energy investments by 2025.

Amory B. Lovins of RMI argues that subsidies for distressed nuclear plants are unjustified because closing high-cost nuclear units and reinvesting their operating expenses into energy efficiency can reduce more carbon than maintaining the plants. He contends that 'baseload' power is not a grid requirement and that variable renewables are more resilient and cost-effective than central thermal plants.

The report argues that California's carpet stewardship program, led by the industry-controlled Carpet America Recovery Effort (CARE), has failed to meet recycling goals and instead increased the incineration of carpet waste. It contends that incineration—including Waste-to-Energy (WTE), cement kilns, and Carpet as Alternative Fuel (CAAF)—is a wasteful practice that violates the California Public Resources Code's waste management hierarchy. The document highlights significant environmental and health risks, noting that burning carpets containing PVC releases dioxins and unregulated nanoparticles. Financially, it claims WTE is the most expensive energy generation method in the U.S. and can lead to municipal bankruptcy. From a climate perspective, it cites CalRecycle data showing that WTE incineration adds approximately 26,000 metric tons of CO2, whereas recycling saves about 36,000 metric tons. The authors recommend that CalRecycle reject CARE as the stewardship organization and mandate an industry-funded program with enforceable recycling targets.

The document criticizes the Trump administration's "one in, two out" executive order, which Earthjustice claims is illegal and prioritizes corporate profits over public health. It highlights the role of the EPA in preventing pollution-related illnesses and argues that the economic and health benefits of environmental regulations far outweigh their costs to industry.
