HEI ACES study of lifetime animal exposure to New Technology Diesel Engine exhaust finds no lung cancer

Green Car Congress

This phase was conducted at the Southwest Research Institute (SwRI) in 2007 and 2008 and was the basis for selecting one HHDD engine/control system for health testing in Phase 3. Countries like China are already moving toward implementing the ultra-low sulfur diesel fuel that is required for these new cleaner technologies.

UN Review of Recent Climate Research Concludes That Impacts Of Climate Change Coming Faster Than Anticipated

Green Car Congress

Significant climate anomalies 2008/2009. The growth in carbon dioxide emissions from energy and industry has exceeded even the most fossil-fuel intensive scenario developed by the IPCC at the end of the 1990s. In 2008, the minimum ice extent was 9% greater than in 2007, but still the second lowest on record. Click to enlarge.
