Evidence from glacier ice: Until it was banned, leaded gasoline dominated the anthropogenic lead emissions in South America

Green Car Congress

The scientists found that lead from road traffic in the neighboring countries polluted the air twice as heavily as regional mining from the 1960s onwards. Apart from combustion of leaded gasoline, major sources of anthropogenic Pb emissions include mining, metallurgical processing, and coal burning. —Anja Eichler, first author.

Study projects thermoelectric power in Europe and US vulnerable to climate change due to lower summer river flows and higher river water temperatures

Green Car Congress

Projected changes in summer mean usable capacity of power plants in the US and Europe for the SRES A2 emissions scenario for the 2040s (2031–2060) relative to the control period (1971–2000). This causes downstream thermal pollution affecting, for example, life cycles of aquatic organisms. Source: van Vliet et al. Click to enlarge.

Plug-In Hybrids Are Cleaner (Even on a Coal Grid) [ to top ] This entire section is finally obsolete -- because we now have a definitive study by the Electric Power Research Institute and the Natural Resources Defense Council. But theyve needed definitive proof that PHEVs wont increase pollution. The GREET 1.6 Why Pay More for a PHEV?
