The report finds that polyester is the most energy-intensive and highest CO2 emitter, while hemp generally has the lowest Ecological Footprint. Cotton, particularly in Punjab, exhibits the highest Ecological Footprint due to low productivity and high land requirements. Water analysis reveals that cotton is extremely water-intensive, requiring between 9,788 and 9,958 litres per kilogram of lint, whereas polyester's water use is negligible in comparison.

The document argues that home lighting efficiency is best achieved through a 'whole-system' approach rather than simple bulb replacement. It highlights the benefits of Compact Fluorescent Lamps (CFLs) and emerging LED technology, while strongly advising against the use of halogen torchieres due to fire risks and energy waste. The briefing also emphasizes the role of lighting controls, task lighting, and daylighting in reducing electricity consumption and improving well-being.

The document describes how automated air/fuel ratio (AFR) controls can optimize the operation of natural gas engines to reduce fuel consumption and emissions. It highlights a case study where the installation of the REMVue system on 51 engines in the Gulf of Mexico led to fuel savings of 18-24% and a reduction of 128 Mcf of methane emissions per unit annually. The economic analysis indicates a total cost of $6.1 million for the project, with an average installation cost of $120,000 per unit and a calculated payback period of 1.4 years based on fuel savings.

The Union of Concerned Scientists analyzed the potential effects of Colorado's Amendment 37, which would require the state's largest electric companies to increase renewable energy use to 10 percent of sales by 2015. Under the most likely scenario, the report projects that the initiative would result in $236 million in consumer savings on electricity and natural gas bills, the creation of 2,000 new jobs by 2020, and a reduction of 3 million metric tons of annual CO2 emissions by 2025. The analysis highlights that wind resources would drive most of the development, providing significant capital investment and tax revenues for rural communities.

The document records a multi-sector call for a U.S. transition to clean energy, arguing that government investment and regulation can simultaneously drive economic growth, reduce oil dependence, and address climate change.

Amory B. Lovins, CEO of RMI, submits comments to NHTSA challenging the technical basis of its proposed rulemaking on automobile fuel economy standards. He argues that NHTSA incorrectly relies on retrospective correlations between vehicle weight and safety, which fail to account for modern materials like advanced polymer composites and high-strength steels. Lovins asserts that these materials can create vehicles that are simultaneously large, lightweight, and safe, thereby eliminating the perceived tradeoff between fuel economy and crashworthiness. He recommends that CAFE standards be performance-based, technology-forcing, and based on size metrics rather than mass to avoid incentivizing a 'mass arms race' and to maintain the global competitiveness of U.S. automakers.

The document emphasizes that scientific uncertainties should not justify delaying preventive actions against climate change. It highlights robust facts, such as the role of greenhouse gases and the delaying effect of aerosols and ocean inertia, to argue for a precautionary approach. The author notes that current efforts, including the Kyoto Protocol, are insufficient to stabilize atmospheric concentrations, and calls for industrial countries to lead emissions reductions to ensure global equity and sustainable development.

The report compares conventional, advanced, and hybrid-electric diesel and gasoline vehicles across five passenger vehicle classes. It finds that while diesel engines offer higher inherent fuel economy, they are less cost-effective than improved gasoline vehicles for reducing oil use and heat-trapping gases due to higher up-front costs and the higher petroleum intensity of diesel fuel. The report also highlights significant public health concerns, noting that diesel vehicles historically emit substantially more toxic soot and nitrogen oxides than gasoline vehicles. While new federal Tier 2 standards aim to close this gap, the report argues that diesel's future depends on overcoming technical challenges in emissions control and ensuring real-world performance matches certification. It recommends maintaining strict emissions standards, modifying CAFE to use energy-equivalent measures, and expanding inspection and maintenance programs to include diesel vehicles.

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.

The document outlines strategies for reducing the energy footprint of the kitchen, focusing on the life cycle of food and the efficiency of appliances. It highlights that refrigerator energy use has dropped over 60 percent in twenty years due to technology and standards, though older models remain costly. For cooking, it argues that habits are more impactful than technology, recommending smaller appliances like microwaves and toaster ovens over conventional ovens. It also emphasizes the environmental benefits of buying local, organic food and implementing composting and recycling to reduce the millions of tons of food and packaging waste entering U.S. landfills.

The report evaluates a 'Power Switch' scenario for Japan's power sector, which emphasizes renewable energy, natural gas substitution for coal, energy efficiency, and a gradual nuclear phase-out. Compared to a Business As Usual (BAU) scenario, the Power Switch approach could reduce 2020 GHG emissions by 31%, avoiding nearly 2.0 billion tonnes of CO2 equivalent between 2000 and 2020. The net cost of this transition is estimated at 1.1 trillion yen over the period, or 850 JPY per tonne of CO2 equivalent, largely offset by reduced fuel import costs.

The report analyzes the agricultural sector in Central America, noting a trend where imports grow faster than exports and a heavy reliance on external technology for dynamic crops. It identifies significant environmental degradation caused by the high use of pesticides in banana and cantaloupe production and carbon emissions from sugar cane burning. The authors argue that while the region has extensive environmental legislation, it is rarely enforced. To promote sustainable development, the document recommends establishing non-distorting support mechanisms, negotiating special treatment for 'sustainable' products in trade agreements like CAFTA and the FTAA, and creating a General System of Green Preferences (SIGPREVERDE) for developing countries.

The report examines subsidies within the Southern African Customs Union (SACU), focusing on South Africa's manufacturing, agriculture, and energy sectors. It finds that most domestic incentives are WTO-compliant, though the Duty Credit Certification Scheme for textiles is an exception. The agricultural sector has seen significant deregulation since the 1980s, resulting in low Producer Support Estimates (PSE) for most commodities. However, the region remains vulnerable to foreign subsidies, particularly the EU's Common Agricultural Policy (CAP) and the U.S. Farm Bill, which distort markets for sugar and beef. In the energy sector, South Africa's heavy reliance on coal creates high carbon intensity and a lack of incentives for renewable energy due to low coal prices.

The report evaluates U.S. state commitments to renewable energy, finding that while technical potential is vast, most states lack binding policies. It grades states based on renewable electricity standards (RES) and funds, noting that a small number of states, led by California and Nevada, drive most projected gains, while 34 states received failing grades. The authors argue for a national renewable electricity standard to ensure equitable and cost-effective growth.

The report analyzes the drivers of U.S. energy insecurity, highlighting the high dependence on oil imports from unstable regions and the vulnerability of domestic infrastructure like the Trans-Alaskan Pipeline System. It argues that energy productivity gains since 1975 have been the nation's largest energy 'source' and that further efficiency improvements in light vehicles could displace net imports from the Persian Gulf.

The report by Scientists for Global Responsibility (SGR) critiques the 2003 invasion of Iraq, asserting that the US administration's justifications—such as eliminating weapons of mass destruction (WMD) and promoting democracy—are insincere. SGR argues the true drivers are 'full spectrum dominance' and the desire to control strategic oil reserves to reduce reliance on Saudi Arabia. The document details severe humanitarian risks, including potential malnutrition for 1.26 million Iraqi children, and environmental damage, including CO2 emissions from the invasion estimated to equal one year of total UK emissions. It concludes by advocating for a shift from military spending toward solving global poverty, water scarcity, and climate change through renewable energy development.

The document outlines a framework for 'green building' that prioritizes materials with low embodied energy, minimal toxicity, and high recyclability. It argues that the Industrial Revolution's reliance on fossil fuels and non-local materials has stressed global life support systems and degraded indoor air quality. The author recommends specifying low-VOC products, utilizing local masonry or adobe, and considering the high carbon footprint of cement, which accounts for over eight percent of human CO2 emissions worldwide. The guide also compares the energy efficiency and environmental trade-offs between steel and wood framing, while advocating for engineered wood products and reclaimed timbers to protect old-growth forests.

The document compares the impacts of the SEER 13 and SEER 12 energy efficiency standards for central air conditioning units in the U.S. It asserts that SEER 13 provides significantly greater energy savings, lower carbon emissions, and reduced power plant construction compared to SEER 12, while dismissing claims that the higher standard imposes prohibitive costs or size constraints on consumers and manufacturers.

The document asserts that human use of fossil fuels has disrupted the Earth's climate balance, leading to a one degree Fahrenheit increase in global mean temperature over the last century. While some regions like the Midwest might see initial benefits such as increased crop yields, the text warns that failure to reduce emissions could lead to temperature increases of 5 to 10 °F, resulting in severe consequences for the U.S. and dire outcomes for poor developing countries.

The document is a formal appeal to the President of the United States to participate in the 2002 Johannesburg Summit. It argues that the U.S. has a special responsibility to lead on sustainable development and environmental protection, citing urgent global crises including climate change, deforestation, and biodiversity loss. The signatories request that the U.S. ratify Rio treaties, reduce carbon dioxide emissions, and support renewable energy technologies.
