The analysis finds that EVs generally produce lower global warming emissions than average compact gasoline vehicles, though their relative performance against high-efficiency hybrids depends on the regional electricity grid's fuel mix. In 'BEST' regions, EVs outperform 50 mpg hybrids, while in 'GOOD' regions, some hybrids remain a better choice for emissions. Financially, EV owners in 50 major U.S. cities can save between $750 and $1,200 annually in fuel costs when using the lowest-cost electricity plans, with significant additional savings available through time-of-use (TOU) rate plans, particularly in California.

The brief, filed by a coalition of physicians, scientists, and environmental advocates, contends that the natural gas industry systematically suppresses public health data through federal exemptions, state laws, and confidential legal settlements. It argues that the public interest in understanding the health risks of hydraulic fracturing—such as water contamination and air pollution—outweighs the private interests of gas companies in maintaining secrecy. The authors specifically highlight the Hallowich family's experience with deteriorating health due to nearby gas operations and urge the court to reverse a lower court's decision to seal the case records.

The document argues that the EPA's proposed air pollution standards for the natural gas sector are essential for protecting public health and the environment, particularly through the implementation of 'green completion' technology to capture methane and smog-forming emissions from fracked wells. The authors contend that these standards are cost-effective, as the sale of recovered gas offsets compliance costs, and that they will not hinder domestic production, citing examples from Colorado and Wyoming. The letter specifically rejects proposed industry loopholes from the American Petroleum Institute (API), such as VOC percentage thresholds and implementation delays, which the authors claim would exempt millions of tons of pollution and undermine the standards' effectiveness.

The Union of Concerned Scientists argues that U.S. farm policy disproportionately supports non-perishable commodity crops while hindering 'healthy-food' farms—those growing fruits and vegetables using sustainable or organic practices. Key barriers include planting restrictions in subsidy programs, a lack of accessible whole-farm-revenue insurance, and credit constraints for small-scale or diversified operations. The report recommends eliminating planting restrictions, reforming the Adjusted Gross Revenue (AGR) insurance pilot to be more flexible and national in scope, removing arbitrary surcharges for organic farmers, and expanding micro-lending programs to support rural economic development.

A coalition of environmental organizations argues that the EPA's proposed rules for the oil and gas industry are insufficient. They demand the direct regulation of methane, the inclusion of existing sources, the elimination of exemptions for certain wells, and the regulation of hydrogen sulfide and particulate matter. The coalition also calls for more stringent toxic air pollutant limits and a more comprehensive health risk assessment for vulnerable populations.

The report finds that U.S. power plants withdraw massive volumes of freshwater, with coal and nuclear plants being the most water-intensive. This demand contributes to water-supply stress in hundreds of watersheds and is exacerbated by droughts and heat waves. The authors highlight significant gaps and inaccuracies in EIA reporting and advocate for 'water-smart' energy choices, such as dry cooling and low-water renewables, to ensure energy reliability and water security.

The report argues that US utilities must move beyond a 'business-as-usual' mindset to meet increasingly aggressive energy efficiency targets. It proposes a 'turbocharging' strategy that combines 'broader' savings (acquiring more participants) with 'deeper' savings (increasing energy saved per participant). The authors identify systemic barriers, including utility complacency, lack of competitive experience, and rigid regulatory frameworks, and offer a framework of recommendations centered on improving marketing, sales execution, reducing transaction costs, and embracing collaboration with third-party partners and regulators.

The briefing argues that traditional utility rebate programs, which focus on single-technology upgrades, yield only 1 to 5 percent whole-building savings. In contrast, a 'deep retrofit' approach—optimizing the building as a whole—can achieve 30 to 50 percent savings. To scale this, the authors propose the 'Deep Energy Efficiency Pays' (DEEP) program, which provides an additional incentive for projects that meet a specific energy savings threshold (e.g., 30 percent). This incentive is designed to 'tip' the economics of projects that would otherwise be financially unviable for building owners. The document highlights the Empire State Building as a successful example of a deep retrofit and discusses existing programs in California and Connecticut as precursors to this model.

The document is a citizen petition submitted to the EPA requesting the promulgation of rules under the Toxic Substances Control Act (TSCA) to address the lack of public and regulatory information regarding chemicals used in oil and gas exploration and production (E&P Chemicals). The petitioners argue that current regulatory gaps—including the 'Halliburton Loophole' and inadequate Material Safety Data Sheets (MSDS)—allow the industry to conceal toxic fluids that pose unreasonable risks to human health and the environment. The petition cites evidence of groundwater contamination, air quality degradation, and animal fatalities across several U.S. states. It specifically requests that the EPA mandate toxicity testing under TSCA section 4, require detailed reporting of chemical identities and volumes under section 8(a), call in records of adverse reactions under section 8(c), and require the submission of all existing health and safety studies under section 8(d).

The document details the severe health risks of diesel particulate matter, including 21,000 annual deaths and increased cancer risks. It advocates for the Diesel Emission Reduction Act (DERA) to clean up the existing fleet of 11 million heavy-duty engines and proposes the Clean Construction Act of 2011 to integrate emission controls into federally funded transportation projects, capping costs at 1% of project totals.

The Clean Air Task Force (CATF) proposes a 'Clean Construction' policy for U.S. transportation projects, requiring the use of emission control technologies like Diesel Particulate Filters (DPF) in PM2.5 non-attainment and maintenance areas. The proposal suggests funding these upgrades through project change orders, capped at 1% of total project costs, to mitigate severe health risks associated with diesel pollution while ensuring a fair bidding process for contractors.

The document presents data on the freshwater requirements of U.S. power plants, highlighting that coal and nuclear power are the primary consumers of freshwater for cooling. It details the distribution of cooling systems across the U.S. and identifies specific watersheds where power plant water use significantly impacts the Water Stress Index (WaSSI).

A three-year study on a New York dairy farm found that implementing near-stream best management practices, such as exclusionary fencing and cattle crossings, significantly reduced soluble reactive phosphorus (SRP) concentrations in streamwater, while having little effect on nitrate nitrogen levels.

The document examines the technology and global status of offshore wind energy, noting that while Europe leads in operational capacity, the United States has significant untapped potential. It details the technical requirements for different water depths, the regulatory frameworks in countries like Denmark, and the specific siting and permitting complexities in the U.S. The text also addresses public concerns regarding tourism, wildlife, and military radar, while highlighting the economic benefits in terms of job creation and greenhouse gas reduction.

The Union of Concerned Scientists reports that the NRC has inconsistently enforced safety regulations for radioactive releases, allowing numerous accidental leaks to occur without sanction. While the NRC previously issued sanctions for monitoring and control failures, the report claims the agency has tolerated 27 accidental releases over a four-year period with impunity, effectively breaching its safety contract with the public.

The document argues that implementing fuel-efficiency standards and technologies for medium- and heavy-duty trucks in the U.S. would generate significant job growth, increase GDP, and reduce greenhouse gas emissions. It highlights that while these vehicles represent only 4% of U.S. highway vehicles, they consume over 20% of fuel, and that widespread adoption of efficiency technologies could save 100 billion gallons of fuel by 2030.

The report argues that improving the fuel economy of medium- and heavy-duty trucks through advanced technologies would create significant net job growth, increase GDP, and reduce global warming emissions, provided that policy interventions overcome existing market barriers.

The author advocates for a shift away from oil in the United States by implementing carbon or petroleum taxes to reduce demand and replacing petroleum-based fuels and materials with sustainable alternatives. The text highlights the potential for biofuels in transportation and heating, as well as the use of biomass for industrial chemicals and building products, emphasizing that such a transition must be grounded in sustainability to protect ecosystems.

The document argues that improving the fuel economy of medium- and heavy-duty trucks in the U.S. would create significant job growth, increase GDP, and reduce greenhouse gas emissions, provided that market barriers are overcome through performance standards and incentives.

The Union of Concerned Scientists argues that current U.S. biofuels policy is costly and ineffective, primarily supporting mature food-based industries while cellulosic biofuels remain stalled. The report proposes the 'Billion Gallon Challenge' to provide capital support for the first billion gallons of annual cellulosic capacity and a 'Biofuels Performance Tax Credit' to replace existing credits with incentives based on actual life-cycle emissions reductions.
