The report argues that the Trump administration has systematically undermined science-based decision-making, which exacerbates existing environmental and health inequities for marginalized communities. It documents rollbacks in air and water pollution enforcement, the suppression of scientific data, and the dismantling of social safety nets and community participation programs. The document provides specific examples of these failures, such as the refusal to ban the pesticide chlorpyrifos and the suppression of PFAS contamination data, while highlighting state and local victories where communities have successfully pushed back against these trends.

The study finds that the extreme two-day rainfall during Tropical Storm Imelda in September 2019 was made more likely and more intense by anthropogenic climate change. Observational data suggests the probability of such an event has increased by a factor of 2.6 since 1900, while climate model synthesis indicates a probability increase of 1.5 to 3.1 times and an intensity increase of 9% to 21%. The report also notes that rapid urban expansion and loss of impervious cover in Southeast Texas have exacerbated flooding risks for approximately 6.6 million people in the impacted counties.

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 provides a comprehensive overview of 'green jobs', highlighting that the U.S. energy efficiency sector employs over 3 million people and the global renewable energy sector employed 11 million people in 2018. It details specific employment figures for various technologies—such as solar, wind, and biofuels—and identifies China as the global leader in renewable energy employment. Additionally, it notes the emergence of climate adaptation and resilience jobs, though standardized data collection for these roles remains limited.

The report analyzes future extreme heat in the US, finding that a 'no action' emissions scenario would lead to a staggering increase in dangerously hot days, particularly in the Sunbelt and Midwest, while rapid action could significantly limit these risks.

The briefing highlights a coastal sediment crisis in the Gulf of Mexico caused by human activity for the navigation industry. It outlines current state-level sediment efforts in Louisiana, Florida, Alabama, Texas, and Mississippi, and identifies the US Army Corps of Engineers (USACE) districts in Jacksonville, Mobile, and Galveston as regional leaders in RSM. To improve resilience, the author recommends that Congress reform the USACE 'federal standard' of least cost disposal, update Benefit-Cost-Ratio (BCR) calculations, support legislation like the Living Shorelines Act and Coastal Communities Adaptation Act, and shift toward sustained upfront federal investment rather than relying on post-storm funding.

The document explores nature-based solutions—such as wetlands, oyster reefs, and dune restoration—as alternatives or complements to traditional 'gray' infrastructure for mitigating storm surge, flooding, and erosion along the U.S. Gulf Coast. It highlights the role of regional partnerships like the Gulf of Mexico Alliance and the U.S. Fish and Wildlife Service's Coastal Program in implementing these strategies. A significant portion of the discussion focuses on the 'sediment crisis,' arguing for the beneficial use of dredged material to rebuild marshes and beaches. The panel concludes with legislative recommendations for the U.S. Congress, including reforming Army Corps of Engineers' cost-benefit ratios and funding pre-disaster mitigation.

The report explores how large utility customers, including cities and corporations, can achieve high renewable energy goals through various procurement models. It details options such as green tariffs, sleeved PPAs, and community solar, while addressing the critical role of Renewable Energy Certificates (RECs) in accounting and disclosure. The document emphasizes the need for collaboration between utilities, customers, and regulators to ensure that the transition to carbon-free energy is cost-effective, avoids cross-subsidization of non-participants, and maintains grid reliability.

The report identifies a significant surge in global oil and gas pipeline development, with North America leading the trend. It contends that this expansion is predicated on a 'super cycle' of demand from Asia that is incompatible with IPCC climate goals and threatened by the rise of renewables and competing production in other regions. The authors compare the current situation to the 2011–2016 coal mining crash, warning that high leverage and a loss of 'social license' create a high risk of stranded assets.

The Union of Concerned Scientists asserts that the United States has the lowest electoral integrity among advanced industrial democracies, which undermines the ability to create science-based policies. The report links voter suppression and gerrymandering to poor public health and environmental outcomes, citing examples in Georgia, Michigan, North Carolina, North Dakota, and Texas. It advocates for reforms such as automatic voter registration, nonpartisan redistricting, and public campaign financing to reduce the influence of 'dark money' and corporate interests on government decision-making.

The document argues that consolidated interim storage of high-level radioactive waste is a risky and counterproductive plan that creates unnecessary transportation and security hazards. It highlights two specific license applications—one by Waste Control Specialists in Texas and another by Holtec International in New Mexico—and asserts that these projects face significant legal, technical, and community opposition. The authors claim that such facilities would not accelerate the move to permanent repositories and could instead become de facto permanent sites, while posing severe risks of radiation exposure and economic disaster in the event of a transport accident.

The report finds that a significant portion of the U.S. coal fleet is now more expensive to operate than replacing it with new local wind and solar power. In 2018, 74% of the fleet was 'at risk' of being undercut by renewables, a figure projected to rise to 86% by 2025. The analysis emphasizes that these findings are conservative because they only consider resources within 35 miles of existing plants and do not account for broader transmission expansion or combined energy portfolios.

The Clean Air Task Force supports the USE IT Act as a critical tool for developing a diversified portfolio of low-carbon technologies. The testimony emphasizes that meeting global temperature targets requires not only emission reductions but also negative emissions, which can be achieved through carbon capture utilization and storage (CCUS) and direct air capture (DAC). The author argues that the USE IT Act will catalyze innovation through prize competitions and facilitate the expansion of the US CO2 pipeline network, which currently stands at 4,500 miles but may need to reach 66,000 miles to support large-scale deployment.

The report finds that the 45Q tax credit could lead to the annual capture and storage of approximately 49 million metric tonnes of CO2 by 2030 in the U.S. power sector, primarily through retrofits on coal and natural gas combined cycle (NGCC) plants. This deployment is found to be complementary to renewable energy growth and could meet two-thirds of the 2030 U.S. power sector goal set by the International Energy Agency (IEA) to limit global temperature rise to 2 degrees Celsius. The analysis emphasizes that the economics of the 45Q credit make enhanced oil recovery (EOR) more favorable than saline storage, necessitating rapid infrastructure development to realize the credit's full potential.

The report details how plastic pollution constitutes a global public health crisis, affecting humans at every stage of the plastic life cycle. It examines the toxic emissions from fracking and petrochemical refining, the leaching of endocrine disruptors from packaging, and the health risks associated with microplastics and incineration. The document emphasizes that current fragmented regulatory approaches are insufficient and calls for a global reduction in plastic production to protect human rights and health.

The report details how plastic poses distinct health risks at every stage of its supply chain. It highlights toxic emissions during extraction and refining, the leaching of endocrine disruptors and carcinogens during consumer use, and the release of heavy metals and dioxins during waste incineration. The document emphasizes that microplastics and associated chemicals contaminate the global food chain, water supplies, and human tissues, while noting significant knowledge gaps and a lack of industry transparency regarding chemical compositions.

The report details how plastic creates a global health crisis through a complex life cycle. It identifies toxic emissions during fossil fuel extraction (fracking) and refining, the leaching of endocrine disruptors and carcinogens from consumer products, and the release of hazardous metals and dioxins during waste incineration. It further examines the pervasive presence of microplastics in the food chain, drinking water, and human tissues, linking them to inflammation, oxidative stress, and various chronic diseases. The document emphasizes that marginalized communities bear a disproportionate burden of these risks and calls for a transition away from plastic production based on human rights and the precautionary principle.

An analysis of 16 Texas coal-fired power plants reveals that 100% of those with available records are leaking unsafe levels of contaminants, such as arsenic, boron, cobalt, and lithium, into groundwater. The report argues that both the 2015 federal Coal Ash Rule and the Texas Commission on Environmental Quality's proposed state program are inadequately protective, particularly regarding the use of contaminated background wells and the practice of 'closure in place' for ponds in contact with groundwater. It highlights the San Miguel Electric Plant as the most contaminated site and provides specific evidence of regulatory violations by operators including NRG and CPS Energy.

The report documents a systemic effort by the Trump administration to marginalize scientific expertise in federal policymaking. Key tactics identified include the disbanding of science advisory committees, the suppression of research on climate change and public health, and the creation of a 'culture of fear' that encourages scientist self-censorship. The authors highlight specific failures in the EPA, DOI, and HHS, while providing a roadmap for the 116th Congress to restore scientific integrity through oversight and legislative reform.

Voters in six key U.S. swing states show strong support for policies that reduce fossil fuel emissions and expand renewable energy, with many indicating they are more likely to support political candidates who champion these initiatives. The report finds that climate change is a salient issue, particularly among Democratic-leaning voters, and that a majority of voters in these states recognize a link between climate change and worsening extreme weather. There is broad preference for prioritizing wind and solar energy over natural gas or nuclear power to meet state energy needs, and voters generally believe that transitioning to renewables will benefit their local economies and public health.
