Emission Cuts Lead To Cleaner California Air

Cuts in diesel emissions have drastically reduced the amount of global warming black soot air pollution in California, potentially valuable information for saving the world’s climate from a predicted catastrophe, says a new study, reports Peter Fimrite at the San Francisco Chronicle. The study found that regulations limiting emissions from diesel-powered trucks, buses and off-road vehicles have taken the equivalent of 4 million cars off California roads every year since the late 1980s, in terms of reduced pollution. “We are all breathing cleaner air because of regulations in diesel combustion, but this study shows there was a huge co-benefit of mitigating climate change,” said the lead researcher of the University of California study. He wants to take this message to the rest of the planet, because if the California experience can be replicated globally, then humanity can substantially dent climate change. Besides causing health problems, black carbon has been identified as the second-largest contributor to global warming behind carbon dioxide. Despite these observed benefits, however, reports Maria Gallucci at InsideClimate News, the regulations are now threatened by legal challenges from fossil fuel and ethanol companies.

Join the swelling numbers of voters TELLING Congress they’ll vote for Clean Energy candidates here: http://signon.org/sign/we-are-the-clean-99?source=c.em.cp&r_by=487176 . This is an ongoing campaign (the next Congressional election is in 2 years!) so please, spread the word. It’s our way of telling Congress that a strong clean energy voting bloc is out there. This is how YOU can make a difference.
