The Clean Car Standards: Background and Frequently Asked Questions
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.

IMPORTING POLLUTION
The report argues that RGGI's design, which caps emissions only for power plants within participating states, creates a price advantage for imported electricity from coal-heavy states like West Virginia and Pennsylvania. This 'leakage' is exacerbated by excess capacity in existing coal plants and planned transmission upgrades that facilitate power flow from west to east. The authors suggest that RGGI states should implement retail-level carbon caps, prohibit contracts with high-emission plants, and prioritize transmission projects aligned with climate goals to prevent the expansion of coal-based power.

Global Warming Case Taken Up By Supreme Court Statement of Norman Dean, Executive Director, Friends of the Earth
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.

A Multi-City Investigation of the Effectiveness of Retrofit Emissions Controls in Reducing Exposures to Particulate Matter in School Buses
The study identifies two primary sources of in-cabin pollution in conventional school buses: the tailpipe and the engine crankcase. It finds that while diesel particulate filters (DPF) combined with ultra-low sulfur diesel (ULSD) eliminate ultrafine particles, black carbon, and PAH, they do not reduce fine particulate matter (PM2.5) because that pollutant originates from the crankcase. The most effective solution for comprehensive elimination of all measured particles is the combination of a DPF, ULSD, and a Donaldson Spiracle closed-crankcase filtration device.

SURRY NUCLEAR POWER PLANT
The Union of Concerned Scientists (UCS) monitored 10 US nuclear power plants and found a "serious breakdown in quality assurance," noting that internal auditors failed to identify any of the 200+ reported incidents. The study found that 44 percent of problems were caused by poor procedures and 35 percent by worker mistakes. While some plants like Surry and Oyster Creek demonstrated proactive safety cultures, others like LaSalle and Sequoyah showed systemic failures, including ignored warnings and repetitive errors. UCS recommends better training for auditors and workers, revised procedures, and stronger NRC enforcement.

The AES Corporation (A)
The AES Corporation, an independent power producer, faced a conflict between its strategy of using low-cost coal for electricity generation and its commitment to social responsibility, specifically regarding greenhouse gas emissions. For its Thames plant in Connecticut, which was projected to emit over 15 million tons of carbon over 40 years, the company evaluated four offset alternatives: promoting energy conservation through lighting retrofits, employing carbon scrubbing technology, implementing reforestation projects in tropical developing countries, or shifting its long-term strategy toward natural gas and renewables. While natural gas and renewables offered lower emissions, they presented higher operating costs or intermittency issues. Reforestation was identified as a cost-effective method to sequester carbon while providing additional social benefits.

Climate change is driving spring warming in 98% of U.S. cities analyzed
Climate Central analysis reveals that human-caused climate change is the primary driver of spring warming in 98% of 241 analyzed U.S. cities between 1970 and 2025. On average, spring temperatures in these cities rose by 2.6F, with the most significant warming occurring in the Southwest, South, and Southeast. The analysis indicates that 69% of these cities had all of their spring warming explained by human-caused climate change. This trend is associated with an increase in warmer-than-normal spring days, which the report links to prolonged allergy seasons, heightened wildfire risk, and reduced snow-fed water supplies in the western U.S.
