The Union of Concerned Scientists (UCS) warns that Louisiana's current regulatory trajectory could lead to up to $26 billion in electricity system costs and $3 billion in public health damages between 2026 and 2041 due to data center growth. The report highlights a systemic overreliance on fossil gas, which is projected to peak in 2038, and criticizes the Louisiana Public Service Commission (LPSC) for a lack of transparency and inadequate ratepayer protections, specifically citing the 'Lightning Amendment' and the Entergy/Meta project as examples of risky policy. UCS recommends reforming the Integrated Resource Planning (IRP) process, implementing standardized tariffs for data centers, and expanding wind, solar, and grid connectivity to reduce costs and emissions.

The report argues that the United States can meet surging electricity demand from AI data centers using clean energy while phasing out fossil fuels, provided that stronger state and federal policies are implemented. It warns that under current policies, data center growth will increase reliance on gas and coal, leading to higher emissions and significant costs for ratepayers. Conversely, adopting clean energy policies—such as restoring federal tax credits and implementing carbon-free electricity standards—could save trillions of dollars in climate and health damages, far outweighing the costs of the energy transition.

The document argues that the market price of fossil fuels fails to account for significant 'hidden costs' or externalities occurring during extraction, transport, and combustion. It details the severe health impacts of coal mining, such as black lung and cardiovascular disease, and the environmental degradation caused by mountaintop removal in Appalachia. The paper also examines the risks of oil and gas drilling, including methane leakage, water contamination from fracking, and catastrophic spills. Finally, it quantifies the economic burden of air pollution and global warming emissions, contrasting these with the lower impacts of renewable energy sources.

The Global Climate and Health Alliance (GCHA) provides legal and scientific commentary to the Inter-American Court of Human Rights, detailing how climate change exacerbates health crises in Latin America and the Caribbean. The document highlights the disproportionate impact of heat, wildfires, air pollution, and vector-borne diseases on vulnerable populations, including indigenous peoples and children. It argues that states have a legal duty under the American Convention on Human Rights and the Paris Agreement to prevent climate-related health harms. The brief recommends a transition away from fossil fuels, the elimination of 'sacrifice zones', and the adoption of sustainable land management to achieve health co-benefits and uphold human rights.

The Union of Concerned Scientists (UCS) reports that over 14 million people live within five miles of 104 ethylene oxide (EtO)-emitting facilities, with a disproportionate impact on people of color and low-income communities. EtO is a known carcinogen used primarily for medical sterilization, and UCS advocates for stricter EPA emissions controls and the adoption of less toxic alternatives.

The document argues that Michigan can meet all electricity needs with wind, solar, and batteries by 2035, leading to significant public health savings, job growth, and emissions reductions, provided the transition is managed equitably.

The document argues that Minnesota can meet its electricity needs with 100 percent renewable energy by 2035, leading to significant public health savings, job growth, and emissions reductions, provided the transition is managed equitably.

The report finds that USCA states can meet 100% of their electricity consumption with renewables by 2035, even with increased demand from electrification. This transition would significantly reduce air pollution, prevent 6,000 to 13,000 premature deaths, and lower average household energy burdens from 3.7% to 3.0% by 2040. While the transition creates substantial net jobs in renewable installation, the authors argue that proactive equity policies are necessary to ensure benefits reach marginalized communities and fossil fuel workers.

The brief asserts that gas appliances release harmful pollutants, including nitrogen dioxide (NO2), fine particulate matter (PM2.5), and carbon monoxide (CO), which lead to respiratory and cardiovascular illnesses. It highlights that indoor pollution levels can be significantly higher than outdoor levels and that vulnerable populations, particularly children and communities of color, are disproportionately affected. Furthermore, it argues that gas appliances contribute to outdoor air pollution and climate change through the emission of criteria pollutants and methane, with methane leaks from stoves and water heaters potentially reaching 110 Gg per year. The document concludes that building electrification is a critical public health intervention that can provide substantial monetized health benefits, estimated at $3.5 billion annually for California.

The report uses the Louisiana Energy Policy Simulator (EPS) to compare a Business As Usual (BAU) trajectory with a Nationally Determined Contribution (NDC) scenario. Under BAU, Louisiana's economy-wide emissions are projected to increase by 30% by 2050. Conversely, the NDC scenario, which aligns with Paris Agreement targets, could reduce statewide emissions by 97% below 2020 levels by 2050. This transition would rely heavily on industrial fuel switching and green hydrogen, potentially creating 263,000 new job-years and avoiding 2,300 premature deaths annually by 2050.

The report advocates for a U.S. federal Clean Electricity Standard (CES) targeting 80% clean power by 2030. It asserts that such a target is technologically feasible, affordable, and reliable, while providing significant co-benefits. Key arguments include the creation of hundreds of thousands of jobs, the avoidance of over $1.7 trillion in health costs through reduced air pollution, and the establishment of a foundation for 100% clean power by 2035. The document highlights that achieving this goal requires rapid infrastructure build-out, specifically approximately 95 GW of wind and solar annually, and emphasizes the need for federal policy to reduce siting and interconnection barriers.

The document supports the introduction of the Ultra Low Emission Zone (ULEZ) in London to combat illegal air pollution, which is primarily caused by road transport and diesel vehicles. It highlights the severe health impacts on children, including reduced lung capacity and increased risk of asthma, and notes that ULEZ could bring London's air within legal limits by 2025. The author criticizes the UK government for failing to hold car manufacturers accountable or provide sufficient financial support for low-income drivers to switch to cleaner vehicles, contrasting this with actions taken in Germany.

The document argues that electrifying heavy-duty vehicles in California can significantly reduce air pollution and global warming emissions while creating job opportunities for underserved communities. It provides a life cycle emissions analysis comparing battery and fuel cell electric buses to diesel and CNG alternatives, finds that current EV technology meets many urban operational needs, and recommends targeted workforce training and financial incentives to ensure an equitable transition.

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 finds that the U.S. Midwest has experienced a significant increase in dangerously hot, humid, and dry summer days, as well as more frequent heat waves, over the last 60 years. Analysis of ten cities indicates that nighttime temperatures and humidity are rising, reducing the relief typically found overnight. These trends are linked to higher risks of hyperthermia and dehydration, particularly for vulnerable populations such as the elderly and low-income urban residents. The document argues for a combination of local adaptation strategies, such as heat-response plans and cooling centers, and aggressive global action to reduce fossil fuel emissions to mitigate future extreme heat events.

The report details the public health dangers of flooding, including drowning, waterborne diseases, mold-induced respiratory issues, and mental health trauma. It argues that climate change increases the frequency and intensity of extreme precipitation and sea-level rise, exacerbating these risks, particularly in areas with combined sewer overflow systems and high-density floodplain development.

The report analyzes the 'hidden costs' of CAFOs, including taxpayer-funded subsidies and externalized environmental and health damages. It argues that CAFOs are not more efficient than medium-sized or pasture-based alternatives but are favored by government policies and the market power of large meat processors. The document details the pollution caused by manure, the rise of antibiotic-resistant pathogens, and the economic decline of rural communities, while proposing policy reforms to level the playing field for sustainable alternatives.

The San Joaquin Valley shares the distinction of having the worst air quality in the United States, driven by a combination of geographic trapping, rapid population growth, and a history of regulatory neglect. The region struggles with chronic ozone and particulate matter (PM) pollution, which disproportionately affects vulnerable populations and damages the agricultural economy. While recent legislation has begun to regulate previously exempt agricultural sources and diesel emissions, the report argues that coordinated action across jurisdictional levels is required to address emissions from sources outside local control, such as heavy-duty trucks and locomotives.

The document criticizes the EPA's 2002 implementation proposal for the 1997 8-hour ozone standard, claiming it unlawfully attempts to shift nonattainment areas from the more protective Subpart 2 requirements to the weaker Subpart 1. It further warns that the EPA's plan to revoke the 1-hour ozone standard would allow areas to abandon critical control measures, such as transportation conformity and maintenance plans, thereby endangering vulnerable populations—particularly children and the elderly—who are susceptible to ozone-linked respiratory issues and asthma.
