The document asserts that biofuel production and transport lead to dangerous spills, leaks, and fires that pollute ecosystems and kill aquatic life. It highlights specific incidents in Missouri and Iowa and notes that cleanup procedures for water-soluble fuels like ethanol are underdeveloped. The text advocates for shifting taxpayer funding from corn ethanol toward energy conservation, public transportation, electric cars, and sustainable solar and wind technologies.

The report analyzes the financial burden on U.S. states that rely on imported coal, identifying those with the highest spending and per capita costs. It highlights a trend of increasing dependence on coal from Wyoming and international sources, particularly in the Southeast and Midwest. The authors argue that these states can redirect funds from coal imports toward energy efficiency and homegrown renewables to create local jobs and reduce carbon emissions.

In 2008, Iowa imported all the coal used by its power plants, resulting in $496 million leaving the state, primarily to Wyoming. Coal accounted for 76.1% of Iowa's electricity generation, making the state the second most dependent on net imports as a share of total power use (78%). To reduce this dependence, Iowa is utilizing energy efficiency programs and renewable energy, specifically wind power, where it has over 3,600 megawatts of installed capacity.

The report analyzes how carbon pricing may affect the US Midwest, a region characterized by high carbon intensity due to coal dependency and a large manufacturing base. While carbon pricing could increase short-term costs for energy-intensive industries, the report argues it presents a long-term opportunity for the region to lead in low-carbon production and 'green collar' jobs. It highlights the Midwest's significant mitigation potential and the role of the Midwestern Greenhouse Gas Accord in driving this transition.

The document outlines the job creation potential of the clean energy economy, citing that renewable energy (RE) and energy efficiency (EE) industries created over nine million jobs in the U.S. in 2007. It provides specific employment projections for various technologies, including wind, solar, bioenergy, and geothermal, across U.S. states and international markets such as Germany, Brazil, and India. The text also compares these figures to employment trends in the fossil fuel and nuclear sectors and details U.S. legislative efforts, such as the Green Jobs Act of 2007 and the American Recovery and Reinvestment Act of 2009, to support workforce training and clean energy deployment.

The report projects that Iowa will face significantly hotter summers, increased flooding in winter and spring, and new threats to agriculture due to climate change. Under a higher-emissions scenario, Des Moines could see over 85 days per summer above 90°F and frequent heat waves similar to the 1995 Chicago disaster. Agriculture is threatened by heat stress for corn and livestock, as well as the northward expansion of pests like the corn earworm. The document argues that Iowa can mitigate these risks by strengthening its renewable electricity standard, promoting energy efficiency, and banning coal plants without carbon capture and storage, supported by federal cap-and-trade and fuel economy standards.

The fact sheet describes biomass cofiring—the simultaneous combustion of biomass and a base fuel, typically coal—as a practical bridge to a renewable energy future. It highlights benefits including linear reductions in CO2 and SO2 emissions, lower capital costs for retrofitting existing boilers, and support for sustainable forest management by creating markets for hazardous fuels. However, it identifies barriers such as feedstock preparation costs and ASTM standards that prevent the sale of biomass-contaminated fly ash. The document suggests that replacing 5% of U.S. coal with biomass could reduce total U.S. emissions by 1.5% within 5-10 years.

As of February 2009, 28 U.S. states and Washington D.C. have implemented renewable electricity standards to increase the share of wind, solar, and bioenergy in their power supplies. The Union of Concerned Scientists projects these standards will support 76,750 MW of new renewable power by 2025, reducing annual carbon dioxide emissions by over 183 million metric tons. While success varies by state—with Texas significantly exceeding its targets—the document argues that state leadership proves these standards can reduce market barriers, justifying a national renewable electricity standard to enhance energy security and fuel diversity.

The document provides a comprehensive overview of wind energy, detailing how turbines convert wind into electricity and the factors affecting power output, such as wind speed and turbine height. It examines the history of the US wind industry, noting the influence of federal tax credits and state renewable energy standards. The text argues that wind power is a cost-competitive, sustainable alternative to fossil fuels that can be integrated into the electric grid without compromising reliability, citing examples from Xcel Energy and various European nations. It concludes that achieving 20 percent wind energy in the US by 2030 is technically and economically feasible.

The report argues that CAFOs are propped up by taxpayer subsidies and the externalization of costs related to pollution and public health. It highlights that these operations, while producing over 50% of U.S. food animals, create massive manure management problems and antibiotic resistance. The author suggests that medium-sized and pasture-based operations are cost-competitive alternatives that would be more viable if subsidies were redirected and antitrust laws were enforced.

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 paper examines the climatic risks of nuclear war, updating the 'nuclear winter' concept with modern climate modelling. It argues that even a regional conflict or the deployment of a single UK Trident submarine could cause significant global cooling, disrupt agriculture, and lead to mass starvation. The author concludes that any arsenal exceeding 5MT poses a global climatic threat and calls for the cessation of the UK's Trident replacement programme.

The briefing examines the European Union's Emission Trading Scheme (EU ETS), the Regional Greenhouse Gas Initiative (RGGI), the Western Climate Initiative (WCI), and the Midwestern Regional Greenhouse Gas Reduction Accord. It argues that for cap-and-trade to be effective, the emissions cap must be sufficiently tight and the distribution of allowances should favor auctioning over free allocation to avoid windfall profits for firms.

The document provides a comprehensive overview of employment trends in the clean energy sector, contrasting the job-creation potential of renewables and energy efficiency with traditional fossil fuel industries. It highlights specific national and state-level projections in the U.S., international trends in the EU and Brazil, and sector-specific data for wind, solar, biofuels, and geothermal energy, while also noting the decline of coal mining employment.

The report finds that U.S. government support for biofuels is extensive and inefficient, with total subsidies projected to exceed $92 billion between 2006 and 2012. The largest contributors are volumetric excise tax credits and market price supports driven by renewable fuel mandates. The analysis argues that these subsidies are an expensive way to achieve energy security and greenhouse gas (GHG) reductions, noting that the cost per tonne of CO2-equivalent displaced is significantly higher than purchasing carbon offsets on climate exchanges. The report warns that pending legislation, such as the Renewable Fuels Standard, could further increase these costs, potentially exceeding $130 billion per year by 2030.

The Union of Concerned Scientists analyzed the potential effects of Washington's Initiative 937 (I-937), which would require large electric utilities to source 15 percent of electricity from eligible renewable resources by 2020 and pursue cost-effective energy conservation. Under an expected case scenario, the report projects that by 2025, I-937 would result in $1.13 billion in cumulative savings on consumer electricity bills, the creation of 2,000 new jobs, and a reduction of 4.6 million metric tons of annual CO2 emissions. The analysis indicates that renewable energy and efficiency investments would be cost-competitive with conventional fossil fuel resources, providing long-term price stability and economic development, including $2.9 billion in new capital investment. Sensitivity analyses suggest that even under pessimistic conditions—such as higher wind costs or the expiration of federal tax credits—the initiative would generally still yield long-term savings and environmental benefits.

The document details the health impacts of radon, lead, mold, and volatile organic chemicals (VOCs) in buildings, particularly schools. It highlights that indoor pollutant levels often exceed outdoor levels and notes the significant financial costs of poor air quality, contrasted with the potential billions of dollars in savings from building improvements and increased worker productivity.

Dr. James Zahn, a former USDA research microbiologist, reported being prohibited on at least 11 occasions from publicizing findings on antibiotic-resistant bacteria in the air near hog operations in Iowa and Missouri. Despite the USDA's stated mission to address human health in swine production, Zahn was barred from presenting his research at 2002 scientific conferences, with supervisors citing the need for discretion on "politically sensitive and controversial issues." This suppression is linked to a February 2002 USDA directive requiring prior approval for research on "sensitive issues," including agricultural practices with negative health and environmental consequences such as global climate change and animal feeding operations.

The document criticizes a 2002 White House directive that allows "intermittent, low levels" of experimental GM genes in the food supply. It contends that the USDA, FDA, and EPA are implementing policies that lack mandatory safety testing, clear contamination limits, or rigorous oversight. The author highlights the risks of allergenicity, toxicity, and pharmaceutical contamination, noting that US exports and food aid spread these contaminants globally. The briefing calls for a return to a "zero tolerance" policy to protect human health and prevent the environmental amplification of GM traits.

A pilot study by the Union of Concerned Scientists found that traditional seeds of corn, soybeans, and canola sold to U.S. farmers are pervasively contaminated with low levels of DNA from genetically engineered varieties. The report warns that porous seed production systems could allow dangerous pharmaceutical or industrial transgenes to enter the food supply and argues that this contamination threatens organic agriculture, international trade, and the integrity of seed repositories.
