The 2007 Renewable Fuel Standard (RFS) aims to reduce global warming pollution from U.S. transportation fuels by mandating renewable fuel use and requiring life-cycle carbon reductions for new facilities. While it targets a reduction of 6 percent in pollution from cars and light trucks by 2022, the Union of Concerned Scientists warns that a loophole exempting most corn ethanol and the lack of regulation for other fossil fuels could negate these benefits. The document advocates for a low-carbon fuel standard to regulate the entire fuel market.

The document defines embodied carbon as the CO2 emitted throughout a product's manufacturing process and discusses the tension between production-based and consumption-based accounting in climate agreements. It evaluates measurement tools like Life-Cycle Assessment (LCA) and ecological footprint analysis, noting significant data gaps and methodological challenges. The paper highlights how embodied carbon affects competitiveness and the potential for trade measures, such as border carbon adjustments, while questioning their compatibility with non-discrimination principles in multilateral trade law.

The report analyzes the environmental and social impacts of China's role as a global leader in e-product manufacturing and e-waste processing. It identifies energy use and toxic chemical release as primary environmental threats and highlights the health risks associated with informal e-waste recycling. The document recommends a National Sustainable E-Product Growth Strategy, a National E-waste Strategy, and an International Action Plan to harmonize standards and manage the responsible trade and disposal of e-waste.

The report examines China's role as a global leader in electronics manufacturing and a primary destination for electronic waste (e-waste). It utilizes Life Cycle Assessment (LCA) to show that the production and use phases—particularly for high-energy appliances like air conditioners—cause the most significant environmental damage. The document highlights the severe health and pollution risks associated with China's informal e-waste recycling sector, particularly in Guangdong and Zhejiang provinces. It argues that while the industry drives economic growth and employment, it creates critical occupational hazards and public health threats. The report concludes with a three-pronged strategy: implementing a national sustainable electronics strategy focused on eco-design, strengthening national e-waste management legislation, and establishing an international action plan to regulate the transboundary movement of e-waste.

The report evaluates the proposed EU Directive's 10% biofuels target for 2020, arguing that sustainability depends on precise GHG accounting and the use of productive feedstocks. It highlights that tropical regions, particularly in sub-Saharan Africa and Latin America, have a significant comparative advantage in biofuel productivity over temperate regions. The authors caution against rigid land-use definitions that could disadvantage Least Developed Countries and emphasize the need to account for indirect land use change (iLUC) to avoid 'carbon debt'. The document recommends harmonizing EU methodology with IPCC guidelines and exploring the use of degraded lands for bioenergy to minimize food-security conflicts.

The document concludes that CFLs are significantly more environmentally friendly than incandescent bulbs over their life cycle. Despite more energy-intensive manufacturing and the presence of mercury, CFLs reduce greenhouse gas emissions by 75% over 10,000 hours of use. The analysis shows that mercury emissions from coal-fired power plants used to power incandescents exceed the mercury released by a CFL's operation and disposal. While frequent on-off cycling reduces a CFL's lifespan and increases its relative assembly emissions, they remain a net win for the environment and typically pay for themselves through energy savings.

The study finds that CFLs provide significant environmental benefits over incandescents, primarily through reduced greenhouse-gas emissions during the operation phase. Despite concerns over their complex manufacturing and mercury content, the analysis shows that the energy efficiency of CFLs outweighs these factors. Even under short operating cycles that reduce lamp life, CFLs remain a net environmental win, though their economic payback period increases. The report also notes that while CFLs release more lead and arsenic than incandescents, they result in lower overall mercury emissions when accounting for the mercury released by coal-fired power plants required to power incandescent bulbs.

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 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.

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.

The brief supports Brazil's ban on retreaded tyres, arguing that the WTO Panel correctly identified the health and environmental risks of tyre waste, specifically the propagation of diseases like malaria and dengue fever. It contends that the Panel properly applied a life-cycle approach to environmental policy and that the level of protection chosen by a Member state is its own prerogative. The authors argue against the requirement for precise quantification of risk reduction, suggesting that qualitative evidence and the precautionary principle are sufficient for justifying environmental measures under Article XX(b).

The 2003 EU Biofuels Directive, intended to support rural economies and reduce emissions, has instead contributed to higher food prices, tropical deforestation, and increased greenhouse gas emissions. Specifically, the conversion of peatlands in Southeast Asia for palm oil has significantly increased global CO2 emissions. The author warns that current life-cycle analyses are insufficient because they often ignore land-use changes and the impacts of displaced food production, urging the U.S. to avoid similar policy mistakes.

The 2003 EU Biofuels Directive, intended to reduce greenhouse gas emissions and support rural economies, has instead driven tropical deforestation, increased global CO2 emissions through peatland destruction, and exacerbated food insecurity. The report argues that current life-cycle analyses are inadequate for predicting these indirect market and land-use effects.

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 document supports Brazil's measures against retreaded tyre imports, emphasizing that such trade shifts waste problems from developed to developing nations. It advocates for a 'life-cycle approach' to assess environmental burdens and links the ban to obligations under the Basel and Stockholm Conventions, as well as the right to health under international human rights law.

The document discusses the tension between the chemical industry's societal benefits and its harmful impacts on human health and the environment, specifically highlighting the 'knowledge gap' in toxicity data. It details the introduction of the EU's REACH regulation as a pivotal shift in chemical safety and burden of proof. The briefing identifies ethical career paths in regulatory implementation, green chemistry, and the design of non-hazardous alternatives to synthetic chemicals.

The report analyzes 15 key principles for the Strategic Approach to International Chemicals Management (SAICM), including integrated chemicals management, precaution, and the polluter pays principle. It provides descriptions, legal origins, and recommendations for integrating these concepts into the SAICM Overarching Policy Strategy and concrete implementation measures.

The report establishes a four-stage 'Impact Pathway' approach—comprising pathway constituent, transport, impact, and valuation models—to quantify environmental externalities in Canadian agriculture. Testing this framework on five indicators (water erosion, phosphorus contamination, GHG emissions, energy efficiency, and wildlife habitat) reveals that while valuation methods are generally well-established, significant data and methodological gaps exist in 'transport modelling' for water-related indicators. The report suggests that watershed-level analysis is the most effective unit for these valuations and proposes integrating these findings into macro-level economic models like CRAM and LUAM.

The report analyzes the economic trade-offs between decentralized and centralized wastewater systems, arguing that while treatment plants exhibit economies of scale, collection networks often exhibit diseconomies of scale. It highlights the financial advantages of modular, 'just-in-time' capacity expansion and the potential for water reuse and nutrient harvesting. The document also details various economic valuation methods for non-market environmental goods and the importance of professional management to ensure system reliability.

The document argues that changing usage habits, such as unplugging devices to avoid standby power, is more effective for energy saving than simply purchasing more efficient hardware. It details the energy profiles of computers, monitors, and peripherals, while highlighting the significant environmental toxicity and global waste issues associated with the electronics life-cycle.
