NEWS: A new study shows that EVs are cleaning up the air in dense urban areas. Researchers used satellite data to see how much nitrogen dioxide was in California’s air. As the number of electric cars and plug-in hybrids rose, neighborhoods had lower NO₂ concentrations. "These findings show that cleaner air isn't just a theory–it's already happening in communities across California," said Sandrah Eckel, Ph.D., associate professor of population and public health sciences at the Keck School of Medicine, and the study’s lead author. “We're not even fully there in terms of electrifying, but our research shows that California's transition to electric vehicles is already making measurable differences in the air we breathe," she added. They also confirmed that neighborhoods that added more gas-powered cars saw a rise in pollution. Finally, the results from the satellite data was replicated using updated data from ground-level monitors from 2012 to 2023.
