The document reports that 55 cellulosic biorefineries were complete, under construction, or planned across 31 U.S. states by July 2008, with an expected capacity of 629.5 million gallons per year. It outlines various conversion technologies and feedstocks, including agricultural residues and energy crops, and details significant financial investments from the U.S. Department of Energy and various state governments to advance the industry.

The document explains how nuclear power plants use water to absorb waste heat and cool equipment, detailing once-through and closed-cycle cooling systems. It highlights the significant volumes of water required, the environmental impact on aquatic life, and the critical role of the Ultimate Heat Sink (UHS) during accidents. The author argues that the primary safety hazard is not radioactive leakage, but rather the failure of water to reach the plant or leaking into the plant.

The document outlines how U.S. consumers can support renewable energy via green pricing, green marketing, and Renewable Energy Certificates (RECs). It contrasts the environmental benefits of renewables—such as wind, solar, and geothermal—against the pollution and health risks associated with coal, oil, nuclear power, and natural gas. It also provides tools for verifying green power claims, including the Green-e certification and the Power Scorecard tool.

The report outlines legislative strategies for U.S. states to increase vehicle efficiency, categorizing them into short-term options—such as HOV lane access for Alternative Fuel Vehicles (AFVs) and Hybrid Electric Vehicles (HEVs), state procurement mandates, and tire labeling—and long-term options, including tax incentives, 'pay-at-the-pump' insurance, and feebate programs. It argues that state action is necessary due to the economic burden of high oil prices, security risks associated with oil dependence, and environmental impacts like carbon dioxide emissions.

The document examines the intersection of land use and energy efficiency, proposing a framework based on 'how' and 'where' we build to reduce fossil fuel dependence. It advocates for 'energy smart' growth, which combines compact, mixed-use development with green building standards and renewable energy. The author provides recommendations for funders to support this merger through research, integrated planning tools, policy incentives, and innovative financing like location-efficient mortgages.

The report details a Harvard School of Public Health study on five power plants (Benning, Chalk Point, Dickerson, Possum Point, and Potomac River) near Washington DC. It finds that these plants are linked to over 250 annual deaths and thousands of respiratory and cardiovascular incidents. The analysis highlights that disadvantaged groups—including those with lower education, African-American children, and elderly diabetics—suffer a disproportionate share of these health impacts. The report argues that implementing readily available pollution control equipment could avoid approximately 75% of these deaths and illnesses.

The report evaluates the emissions of US school bus fleets, finding that the vast majority rely on high-polluting diesel engines that pose significant health risks to children. It advocates for a transition to cleaner alternatives, specifically natural gas, and calls for federal and state funding to replace aging fleets.

The report asserts that while the 1990 Clean Air Act Amendments reduced sulfur dioxide and nitrogen oxide emissions, ecosystems in North America remain damaged due to a 150-year accumulation of acidic compounds. It documents ongoing damage to aquatic life, forests, and wildlife, and argues that biological recovery requires emission cuts up to 80 percent beyond the 1990 mandates. The authors state that affordable technologies, such as scrubbers and renewable energy, are available to achieve these deeper reductions.

The La Pine Community Design Charrette, facilitated by the Rocky Mountain Institute in April 2000, sought to move away from traditional consultant-led planning by involving residents directly in the design process. The workshop focused on creating a walkable town center, improving pedestrian safety along Highway 97, and establishing a greenbelt system along the Little Deschutes River. Key recommendations include reducing excessive commercial zoning to prevent sprawl and concentrating retail into a viable town center of 50,000 to 75,000 square feet. The report outlines specific locations for prospective projects such as a civic center, health center, and performing arts center, while emphasizing the need for 'Green Development' and sustainable infrastructure like 'Living Machines' for wastewater treatment.

The Union of Concerned Scientists (UCS) monitored 10 US nuclear power plants and found a "serious breakdown in quality assurance," noting that internal auditors failed to identify any of the 200+ reported incidents. The study found that 44 percent of problems were caused by poor procedures and 35 percent by worker mistakes. While some plants like Surry and Oyster Creek demonstrated proactive safety cultures, others like LaSalle and Sequoyah showed systemic failures, including ignored warnings and repetitive errors. UCS recommends better training for auditors and workers, revised procedures, and stronger NRC enforcement.

The Bayside Division of Dow Chemical implemented waste reduction through statistical process control (SPC) training and a 'suggestion box' system, rather than the WRAP program used in the Louisiana Division. Bayside's projects were typically smaller, costing under $200,000, and focused on housekeeping and materials handling rather than process design. Funding for these initiatives competed with other capital expenditures within a fixed annual budget allocated to individual plants.

The document details the environmental and health impacts of Alberta's coal-fired power plants, noting that in 2014, 68% of the province's electricity was generated from coal. It highlights that these plants are significant sources of sulphur dioxide, nitrogen oxides, fine particulate matter, mercury, and greenhouse gases, with 2011 emissions totaling 43 megatonnes of GHG. The authors propose a transition plan to reach 0% coal reliance by 2030, increasing renewable energy to 40% and reducing electricity demand through energy efficiency by 20%. The strategy discourages increased reliance on stand-alone natural gas due to production-related GHG emissions and suggests mechanisms for phase-out such as legislated closures, lifespan caps, or carbon pricing.

The Clean Air Task Force (CATF) contends that the EPA's proposed MACT standards for coal-fired utility units violate the Clean Air Act (CAA) by using arbitrary subcategories based on coal rank and flawed statistical methods to inflate emission floors. CATF argues that the EPA has ignored available, cost-effective technologies—such as activated carbon injection and fabric filters—that could achieve significantly higher mercury removal rates. The document further asserts that the EPA is legally obligated to regulate all HAPs emitted by these units, not just mercury and nickel, and that proposed compliance extensions are unauthorized and unnecessary given available labor and equipment resources.

The report argues for a 'fair share' approach to renewable energy siting to replace traditional state-level preemption, which often burdens rural communities. It outlines core principles—such as allowing communities to opt out after meeting a state-assigned target and ensuring all regions contribute—and analyzes how similar mandates in affordable housing (e.g., in Massachusetts and New Jersey) have increased supply despite local resistance. The authors identify key differences between energy and housing, such as the larger physical footprint and specific resource potential of energy projects, and provide a roadmap for policy design and implementation.

The document outlines how states can leverage billions of dollars in federal funding to support the transition to zero-emission medium- and heavy-duty vehicles (MHDVs). It categorizes funding opportunities into manufacturing, procurement, charging infrastructure, workforce development, emissions monitoring, and state planning, providing specific program details, eligibility, and strategic next steps for state officials.

The Appalachian Regional Clean Hydrogen Hub (ARCH2) is projected to create over 21,000 direct jobs, including 18,000 in construction and 3,000 permanent positions, through 11 major projects in Pennsylvania, West Virginia, and Ohio. The initiative involves a broad coalition of partners including project developers like Air Liquide and Plug Power, industrial equipment providers such as Baker Hughes and Bloom Energy, and various government, academic, and labor organizations across the region.

The Clean Air Task Force (CATF) used US EPA COBRA modeling to estimate that retiring four Illinois nuclear plants (Byron, Dresden, Braidwood, and LaSalle) would lead to significant increases in PM2.5 pollution. Over a ten-year period, this shift is projected to cause between 1,200 and 2,700 premature deaths and $10 to $24 billion in monetized damages. While the pollution sources are spread across ten states, the most severe health impacts are concentrated in the Midwest.

The document examines the application of environmental taxes, fees, and charges across different sectors in the U.S., including water, air, solid waste, and hazardous waste management. It distinguishes between revenue-raising taxes and cost-offsetting fees, noting that while many instruments are designed to recover administrative costs, some—such as the federal tax on ozone-depleting chemicals and certain state-level hazardous waste taxes—have demonstrated significant incentive effects in reducing pollution. The report also details specific state-level experiments with variable-rate waste collection and wetland compensation fees.

The document argues that integrating public health and equity into climate policy can broaden political support and save lives, estimating that low-carbon policies could avoid 1 million American deaths annually. It proposes a roadmap of legislative and agency actions, including banning natural gas expansion, transitioning to regenerative agriculture, and electrifying public transit, to align the U.S. with the Paris Agreement's 1.5C target. The brief emphasizes that health co-benefits could offset 10% to 41% of U.S. mitigation costs.

The document provides a comprehensive guide for the 4C-NPS internship program, which trains students to create climate change communication materials for parks in the Washington, D.C. metro area. It outlines two primary communication heuristics—simplifying messages and promoting pro-environmental behaviors—and details the administrative roles, recruitment processes, and academic syllabus used to manage the program.
