The document asserts that the United States must reduce greenhouse gas emissions by at least 80 percent below 2000 levels by 2050 to avoid severe climate impacts. It argues that the cost of action is small relative to the global and national economy, while the cost of inaction is significantly higher, citing potential losses of over 3.6% of U.S. GDP annually by 2100. The text advocates for a policy mix of market-based cap-and-trade systems and sector-specific incentives, warning that 'safety valves' or price caps would undermine investment in new energy technologies.

The document highlights the success of renewable electricity standards in 28 U.S. states and the District of Columbia, noting they are projected to add 76,750 MW of new capacity and reduce annual CO2 emissions by over 183 million metric tons by 2025. It further advocates for a national 20 percent by 2020 standard, which would increase total renewable power to 117,000 MW and reduce projected power plant CO2 growth by 63 percent.

The clean car standards, initiated by California's AB 1493 and adopted by the California Air Resources Board (CARB), comprise regulations for air quality, global warming, and zero-emission vehicles. These standards aim for a 30% reduction in global warming pollution from new vehicles by 2016 and are more stringent than federal Corporate Average Fuel Economy (CAFE) standards, targeting a fleet average fuel economy equivalent of 39.2 mpg by 2020 compared to the federal 35 mpg. As of January 2009, 13 states and the District of Columbia had adopted these standards, which are projected to reduce cumulative global warming emissions by 451 million metric tons of CO2E by 2020 across those 15 jurisdictions.

The report analyzes how sustainability knowledge—comprising both substantive technical data and process-oriented expertise—influences public policy. Through six case studies, it identifies that policy impact is not linear but occurs through instrumental, interactive, political, and enlightenment models. Key success factors include the presence of high-level political 'champions', the use of stakeholder engagement to build legitimacy, and the development of long-term trust between knowledge providers and policy users. The document concludes with ten general suggestions for researchers to enhance their policy relevance, emphasizing the need to balance independent research with user-led collaboration and to communicate findings in accessible, timely formats.

The document details how rising temperatures in the Northwest are reducing springtime snowpack and shifting streamflow timing, which threatens water supplies, hydropower production, and salmon populations. It also highlights risks of increased forest fires, pest infestations, and coastal erosion due to sea-level rise, particularly in the Puget Sound region.

Friends of the Earth welcomes the Supreme Court's decision to review a 2003 EPA ruling that denied the agency's authority to regulate carbon dioxide as a pollutant. The organization argues that the lack of regulation has coincided with a 16 percent increase in global warming emissions since 1990 and contributed to severe weather events and economic losses, such as the $57.6 billion in insurance losses from 2005 hurricanes.

The document presents a collection of data points from multiple research organizations arguing that renewable energy (RE) and energy efficiency (EE) sectors generate more employment per unit of energy or investment than fossil fuels. It highlights national and state-level projections in the US, such as the potential for 4.2 million new green jobs by 2038, and international examples from Germany, Spain, Brazil, and India. Specific technology sectors—including wind, solar, biofuels, and geothermal—are detailed alongside the impact of policy mechanisms like Renewable Portfolio Standards (RPS) and investment tax credits.

Hydroelectric power is a major source of emissions-free electricity that utilizes the hydrologic cycle to generate power via turbines. While it offers a flexible, renewable alternative to fossil fuels, it can cause significant ecological damage, such as blocking fish migration and emitting methane from reservoirs. The document details various turbine types, the role of pumped storage, and the potential for low-impact certification and new development in the U.S. and developing nations.

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 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.

Jonathan Lash, representing the US Climate Action Partnership (US CAP), advocates for a federal cap-and-trade program and a long-term emissions roadmap to transition the United States to a low-carbon economy. He emphasizes that clear federal rules are necessary to avoid a regulatory patchwork of state laws and to provide the market certainty required for large-scale private investment in clean energy technologies.

The petition argues that the EPA's risk assessments for chlorpyrifos are flawed because they ignore robust peer-reviewed data on developmental neurotoxicity, endocrine disruption, and inhalation exposure. The petitioners claim that prenatal and early-life exposure causes permanent cognitive impairment and that the EPA's reliance on a 10% cholinesterase inhibition benchmark is insufficient to protect vulnerable populations. They further highlight that inhalation exposure in rural areas far exceeds dietary exposure and that the U.S. continues to export high volumes of the pesticide to developing countries.

The document examines how international investment agreements (IIAs), particularly bilateral investment treaties (BITs), can undermine domestic public policy and state sovereignty by allowing foreign investors to bypass national courts through international arbitration. It highlights cases in South Africa, the US, and Canada where environmental, social, and human rights policies were challenged. The guide argues for stronger parliamentary scrutiny of these treaties to ensure they do not conflict with constitutional obligations or human rights.

The Ports of Seattle and Tacoma, in collaboration with RMI and the Puget Sound Clean Air Agency, held a workshop to address environmental impacts and operational inefficiencies in container shipping. Participants identified 44 ideas categorized as leadership, partnership, or 'Blue Sky' opportunities. Key recommendations include the electrification of yard hostlers, the creation of a centralized transportation information system, and the implementation of a lease-to-own financing model for drayage truckers to acquire cleaner vehicles. The report also explores long-term 'NuPort' concepts, such as unmanned ships and wind-powered vessels, to minimize total energy expenditure in the global supply chain.

The document examines the failures of the 1976 Toxic Substances Control Act (TSCA) and the subsequent emergence of state-level regulations in the U.S. to manage industrial chemicals. It highlights how state actions, such as bans on polybrominated diphenyl ethers (PBDEs), are influenced by international frameworks like the EU's REACH regulation and the Stockholm Convention on Persistent Organic Pollutants. The author argues that these 'twin levers' of state and international progress are essential for driving the U.S. toward a more sustainable national chemical policy by 2020.

The document establishes that limiting global warming to 2°C requires stabilizing atmospheric heat-trapping gases at or below 450 ppm CO2eq, which necessitates a global cumulative emissions budget of 1,700 GtCO2eq for 2000–2050. For the United States, this translates to a cumulative budget of 160 to 265 GtCO2eq, requiring emissions to be reduced by at least 80 percent below 2000 levels by 2050. The analysis finds that most federal legislative proposals fail to meet these targets, with only the Global Warming Pollution Reduction Act (S. 309) and the Safe Climate Act (H.R. 1590) remaining within the upper budget limit.

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 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 document examines the challenges and successes of linking government goals to budget activities through performance measurement. It analyzes the federal Government of Canada's frameworks, Alberta's 'Measuring Up' system, a healthcare case study at Toronto East General Hospital, and the Oregon Benchmarks system. A central theme is the 'attribution' problem, where high-level social outcomes are influenced by factors beyond government control, necessitating a results chain from activities to high-level outcomes.

The document advocates for the adoption of the Solis bill (H.R. 4800) to implement the Stockholm Convention on Persistent Organic Pollutants in the United States. The signatories argue that the Solis bill ensures timely EPA action, adopts a health-based regulatory standard, and respects state-level protections. In contrast, they claim the Gillmor bill (H.R. 4591) would weaken safeguards by introducing cost-benefit standards and preempting state regulations.
