The effort to clean up California's air may be helping slow down climate change.
A new study commissioned by the California Air Resources Board finds that the reduction of black carbon, or soot levels since the 1980s is comparable to taking 4 million cars off the roads of California.
The study examining the impact of black carbon on the state's climate was led by professor of climate and atmospheric sciences Veerabhadran Ramanathan at Scripps Institution of Oceanography, UC San Diego.
"If California's efforts in reducing black carbon can be replicated globally, we can slow down global warming in the coming decades by about 15 percent, in addition to protecting people's lives," said Ramanathan.
