Automaker Rankings 2007
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.

¿quién se beneficia con los cultivos transgénicos?
The report assesses the first decade of GM crop commercialization, focusing on soy, maize, cotton, and rapeseed. It argues that the promised benefits—such as increased yields and reduced pesticide use—are largely myths. In the US, it notes that GM crops have not increased potential yields and have actually increased overall agrochemical use. In South America, specifically Argentina, Brazil, and Paraguay, the expansion of GM soy is linked to deforestation and increased pesticide use, with GM varieties showing higher susceptibility to drought than conventional ones. In Asia and Africa, the report highlights the failure of Bt cotton in China, India, and Indonesia, citing the emergence of secondary pests and increased farmer indebtedness. It concludes that the primary beneficiary of this technology is Monsanto, which has consolidated control over the global seed market, while small farmers face increased dependency and economic risk.

Essential Elements of U.S. Leadership in Ratifying the Stockholm Convention on Persistent Organic Pollutants (POPs)
A coalition of environmental and health organizations calls on the U.S. Congress to ratify the Stockholm Convention on Persistent Organic Pollutants (POPs). The authors argue that U.S. absence from the treaty harms its international reputation and limits its influence over the convention's success. They propose three criteria for implementing legislation: ensuring timely action on new POPs, respecting state-level environmental laws, and granting the EPA clear legal authority to act without redundant evaluations or cost-benefit balancing tests.

Reforming the Automobile Fuel Economy Standards Program
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 Diesel Dilemma
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.
