The 2006 School Bus Pollution Report Card by the Union of Concerned Scientists finds that U.S. school buses are among the oldest vehicles on the road, with an average age of nine years, and emit nearly twice as much soot per mile as tractor-trailer trucks. The report grades states on tailpipe soot emissions, smog-forming pollution, and the success of their cleanup programs. While some states like California and Washington have made significant strides in reducing soot through retrofits and cleaner fuels, national soot pollution from school buses has only decreased by more than two percent. The document highlights the vulnerability of children to diesel exhaust, which is linked to asthma and lung growth deficits, and argues that substantial federal and state investment is needed for bus replacement and the installation of particulate traps.

The report evaluates U.S. school bus emissions, finding that older diesel buses release significantly more soot than modern alternatives, posing health risks to children. It grades states on soot emissions, cleanup programs, and smog-forming pollution, noting wide performance gaps. The authors recommend a strategy of 'the five Rs'—retrofitting, refueling, replacement, repair, and reduced idling—and call for strengthened federal standards and increased funding to modernize fleets.

In April 2004, air quality modelers from nine EPA regional offices protested a policy change allowing states to select their own baseline years for measuring pollution in 'Class I' areas. This policy emerged from a compromise with North Dakota, which had been out of compliance with the Clean Air Act regarding Theodore Roosevelt National Park, hindering plans for new coal-fired power plants. EPA scientists argued the change 'artificially inflate[s]' baselines to mask policy changes and feared it would set a national precedent, as other states like Colorado, Montana, South Dakota, Utah, and Wyoming sought to follow suit.

Amory B. Lovins challenges the claim that a U.S. hydrogen economy requires a fourfold expansion of nuclear power. He argues that fuel cells will accelerate the decline of nuclear power by providing cheaper energy services. Lovins asserts that the hydrogen needs for the U.S. highway vehicle fleet could be met by wind turbines in North and South Dakota, and that an orderly transition to hydrogen would require less capital, land, and fossil fuels than a business-as-usual oil-based scenario. He further contends that wind power is more cost-competitive than new nuclear plants and that distributed energy resources offer greater economic value than centralized power stations.

The Heartland Hydrogen Hub is projected to create 3,880 direct jobs, including 3,067 in construction and 703 permanent positions. The initiative involves two major projects and is led by the University of North Dakota Energy & Environmental Research Center (EERC) as the prime contractor, with industry sponsors including Atlas Agro North America Corp. and Xcel Energy Services Inc.

Since the 2018 45Q reform, 84 carbon management projects have been announced in the U.S., with a significant surge in 2021. The majority of these projects are industrial-sector initiatives utilizing saline storage, though regional infrastructure in the Midwest is enabling ethanol projects. The power sector accounts for 23% of projects, primarily natural gas and coal plants, while only one large-scale Direct Air Capture plant is planned.

The document outlines the potential for superhot rock geothermal energy in South Dakota, noting that just 1% of the state's estimated resource could provide 49 GW of capacity, which is 30 times the state's 2023 electricity consumption. It argues that superhot rock geothermal is a viable global energy source because it does not require natural underground water sources and provides carbon-free firm power with a significantly lower land footprint than solar, wind, or biomass.

The document details the prevalence of coal ash ponds in Minnesota, highlighting that nine are rated as 'significant hazard' and many lack modern liners due to their age. It argues that Minnesota's regulations are insufficient, failing to require comprehensive groundwater monitoring, composite liners for new sites, or financial assurances for cleanup. Evidence of environmental damage is cited, including groundwater contamination at the Sherburne County Generating Plant and Boswell Energy Center, and a note that low-income individuals are over-represented by 43% in zip codes hosting coal-fired power plants.

The fact sheet outlines the potential environmental and economic benefits of energy efficiency in South Dakota, asserting that specific policies could help the state meet its carbon reduction goals under the EPA's Clean Power Plan while saving residents money.

The document consists of a collection of 45 figures mapping the FSEIS routes for nuclear waste transport through nearly every U.S. state and the District of Columbia.

The document lists the professional backgrounds of various experts, policymakers, and industry leaders participating in the National Clean Fuels Technology & Health Effects Leadership Forum. The presenters include former diplomats, senators, CEOs of renewable fuel associations, and agricultural specialists, with a strong focus on ethanol, biofuels, and environmental legislation.

The report provides a state-by-state breakdown of progress toward 2020 Clean Power Plan benchmarks, noting that some states have exceeded 500% of their goals while others show 0% progress. It highlights the role of energy efficiency, renewable energy standards, and regional initiatives in achieving these targets.

The Great Plains region has experienced increasing average temperatures and shifting precipitation patterns, with winter temperatures in northern states rising by more than 6°F over the last 30 years. Climate change is projected to exacerbate the depletion of the High Plains (Ogallala) aquifer, particularly in the southern region where unsustainable water use and extreme heat are already prevalent. Agriculture and livestock are highly vulnerable; rising temperatures are expected to shift crop zones, increase pest prevalence, and reduce livestock yields, with a projected 10% decline in cow/calf and dairy operations under higher emissions scenarios. Ecosystems, specifically prairie potholes and playa lakes, face threats from altered evaporation and recharge rates, which impacts migratory birds and aquifer replenishment. The document also highlights the vulnerability of 65 Native American tribes on rural lands facing water quantity and quality issues.

The document presents the first estimates of manufacturing subsector-specific energy use for the 10 member states of the Midwestern Governors Association (MGA). It aims to fill a data gap where public sources only provide general manufacturing data, thereby enabling policymakers to better identify energy efficiency potential and strategies that balance environmental and economic outcomes. The paper combines energy-use data with state-by-state policy summaries to highlight trends in industrial energy efficiency and cost competitiveness.

The document details the creation of a dataset identifying 11,309 school bus depots in the U.S. using remote sensing and aerial imagery from the National Agriculture Imagery Program (NAIP). The dataset is intended to support environmental justice analysis regarding air pollution hotspots in underserved communities, as well as electricity grid planning for school bus electrification and climate hazard risk assessment. Findings show that 51% of depots are located within 350 meters of a school, with North Carolina having the highest number of depots (841).

A WWF study finds that post-harvest losses for corn and soy in the US are significantly higher than industry expectations, with corn losses averaging 4.7% and soy 4.5%. These losses result in billions of dollars in economic waste and millions of tons of GHG emissions. The report identifies equipment sophistication and operator experience as primary drivers of loss and argues that reducing these losses can alleviate pressure to convert natural habitats into cropland.

WWF reports progress in combating wildlife crime through the 'Silence of the Snares' analysis in Southeast Asia and the Coalition to End Wildlife Trafficking Online, which has removed over 7,000 prohibited listings. The organization is also addressing zoonotic disease risks by advocating for the closure of unregulated wildlife markets. Species-specific successes include a 16% increase in Nepal's rhino population, the reintroduction of plains bison to the Wolakota Buffalo Range in South Dakota, the installation of a solar-powered borehole to reduce human-elephant conflict in Zambia, and the development of lightweight satellite ear tags for polar bears.
