Catalytic Converters Polluting, EPA Says
From Times Wire Reports
Catalytic converters, designed to scrub smog out of automobile exhaust, are spewing greenhouse gases from tailpipes into the upper atmosphere, the Environmental Protection Agency has concluded. The converters, while breaking down smog-causing nitrogen and oxygen from car exhaust, are also rearranging the compounds to form nitrous oxide, which is more than 300 times more potent than carbon dioxide, the most common of the greenhouse gases.
