The document argues that greenhouse gas emissions from shipping are increasing at an alarming rate and calls for immediate regulatory action by the IMO. It proposes short-term measures including vessel speed reductions, which can reduce fuel bills by up to 40%, and a global carbon tax on marine fuels to fund climate mitigation and adaptation, particularly in developing countries. It also suggests shoreside power and wind power as technical solutions while cautioning against relying on reporting or indexing as substitutes for actual reduction measures.

The testimony argues that broad biofuel mandates, such as those implemented by the European Union, can inadvertently accelerate global warming by driving deforestation and land-use changes to meet feedstock demand. The author warns that using farmland for energy crops displaces food production, leading to the conversion of carbon sinks like forests and wetlands. To avoid these outcomes, the Clean Air Task Force recommends that Massachusetts slow the rush toward broad mandates, develop comprehensive life-cycle analysis tools that account for indirect land-use effects, and prioritize 'niche' feedstocks that do not require substantial farmland, specifically algae, biomass waste, and other waste products.

The document outlines technical options for reducing fuel consumption in heavy-duty trucks, focusing on aerodynamic enhancements for tractors and trailers and the reduction of rolling resistance through tire technology and inflation systems.

The document examines the relationship between vehicle weight, fuel efficiency, and safety. It argues that lightweighting can significantly reduce global greenhouse gas emissions—potentially by up to 11% if combined with plug-in hybrid electric vehicles (PHEVs) and a clean grid—without compromising occupant safety. The author contends that vehicle size and design, rather than mass, are the primary drivers of crashworthiness. The paper reviews statistical literature to debunk the 'weight confers safety' argument and provides examples of aluminum, high-strength steel, and carbon fiber composites being used in safe, lightweight vehicles.

Earthjustice successfully challenged a 2006 U.S. Fish and Wildlife Service (FWS) rule that diminished the critical habitat of the California red legged frog. The lawsuit alleged that political pressure from D.C. officials, including former Deputy Assistant Secretary of the Interior Julie MacDonald, led field scientists to ignore the species' Recovery Plan and exclude essential habitat areas. The case concluded after the FWS proposed a new rule in September 2008 to significantly increase the frog's critical habitat.

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 Union of Concerned Scientists argues that while biofuels can reduce transportation emissions, their actual impact varies widely based on feedstock and production methods. The report advocates for 'well-to-wheel' life cycle analysis to prevent the adoption of high-carbon alternatives like liquid coal and to promote advanced cellulosic biofuels. It specifically highlights California's Low Carbon Fuel Standard as a model for federal policy to create market incentives for the lowest-carbon fuels while maintaining environmental safeguards.

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 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 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 report argues that to avoid dangerous climate change, the U.S. must reduce emissions by at least 80% below 2000 levels by 2050. This target is derived from a global stabilization goal of 450 ppm CO2eq, which provides a medium chance of limiting global warming to 2°C. The authors calculate a U.S. cumulative emissions budget of 160 to 265 GtCO2eq for 2000–2050 and warn that delaying reductions until 2020 would double the required annual reduction rate from 4% to 8%. An assessment of then-current federal bills found that only the Global Warming Pollution Reduction Act (S. 309) and the Safe Climate Act (H.R. 1590) were consistent with the upper limit of the proposed U.S. emissions budget.

The author contends that energy efficiency and decentralized renewables are more profitable and faster to deploy than traditional energy sources. By increasing energy productivity and adopting 'micropower', the U.S. and other nations can eliminate oil dependence and reduce carbon emissions without relying on costly subsidies or mandates. Furthermore, the author suggests that the economic failure of nuclear power will naturally hinder nuclear proliferation by reducing the availability of civilian nuclear materials.

The report examines how asymmetric CO2 pricing leads to carbon leakage and competitiveness distortions, particularly in trade-exposed, energy-intensive sub-sectors. It analyzes quantitative tools like 'Value at Stake' and qualitative strategic factors to identify vulnerable industries. The text evaluates four primary policy responses: free allowance allocation, direct state aid, sectoral agreements, and border adjustments/export taxes, weighing their economic efficiency against legal risks under WTO and EU law.

The Clean Air Task Force (CATF) argues that the MIT "Future of Coal" study relies on outdated data and ignores the commercial availability of carbon capture for IGCC plants. CATF contends that IGCC is a superior alternative to pulverized coal (PC) due to lower emissions of criteria pollutants and a significant cost advantage when 90% carbon capture is implemented. The document highlights that while PC carbon capture remains speculative, IGCC carbon capture is a "commercially proven process." CATF warns that following MIT's recommendation to build efficient PC plants today could lock in high global emissions, particularly in China, and instead advocates for banning new coal combustion plants in favor of rapidly commercializing advanced gasification and geologic storage.

The document argues that traditional integrated resource planning (IRP) is too generation-centric and fails to account for the specific operational, financial, and grid-side benefits of distributed and renewable energy. It introduces the Energy Resource Investment Strategy (ERIS) methodology, which uses probabilistic load and fuel forecasting and portfolio theory to value these resources. Key technical discussions include the use of Effective Load Carrying Capability (ELCC) to measure reliability contributions, the role of geographical dispersion in reducing portfolio variability, and the financial advantages of modular, short-lead-time resources in mitigating the risk of overbuilding capacity.

Earthjustice blocked Florida Power & Light's proposal for a massive coal-fired power plant at the edge of the Florida Everglades in 2007. The Florida Public Service Commission rejected the project based on evidence regarding climate change, lack of energy conservation, and cost effectiveness. Consequently, Florida Power & Light invested $300 million in a 75 megawatt solar thermal facility, completed in 2010, which became the largest of its kind in the eastern United States.

The document argues that shipping emissions are increasing at an alarming rate and that current IMO policies, such as voluntary indexing, are ineffective. It highlights the contribution of CO2, nitrogen oxides, and black carbon to climate change and Arctic melting, while warning that IMO inaction is prompting unilateral measures in the EU and US states like California and Washington. FOEI requests the IMO implement mandatory speed reductions, weather routing, and fuel economy standards, while insisting that these efforts remain separate from MARPOL Annex VI revisions regarding toxic air pollutants.

The Union of Concerned Scientists' 2007 report ranks eight major automakers on their environmental impact, focusing on smog and global warming pollutants. Honda is named the 'Greenest Automaker' for the fourth consecutive time, though Toyota has closed the gap significantly due to hybrid technology and consistent performance across all vehicle classes. The report highlights a stark contrast between the top performers and the 'Big Three' (Ford, GM, and DaimlerChrysler), with DaimlerChrysler ranking as the dirtiest. Key findings indicate that while smog emissions have improved due to tighter regulations, progress on global warming emissions has been minimal since 1998. The analysis also critiques the use of flexible-fuel vehicles (FFVs) as a regulatory loophole that increases overall emissions and notes that diesel vehicles reduce global warming pollution but significantly increase smog.
