Sensor network shows EVs are reducing CO2 emissions in the Bay Area. Is it enough?
A network of air monitors installed in Northern California has provided scientists with some of the first measurable evidence quantifying how much electric vehicles are shrinking the carbon footprint of a large urban area. Explore the section Between 2018 and 2022, the region’s carbon emissions fell by 1.8% each year, which the Berkeley researchers concluded was almost exclusively owed to drivers switching to electric vehicles, according to a study published Thursday in the journal Environmental Science & Technology. While the findings confirm the state’s transition to zero-emission vehicles is substantially lowering carbon emissions, it also reveals these reductions are still not on pace to meet the state’s ambitious climate goals. Although cars and trucks are the state’s largest source of carbon emissions, it underscores the need to deploy zero-emission technology inside homes and for the power grid. We don’t yet see significant movement in those, but policy pushing on those is not as far ahead as policy on electric vehicles.” Although cities only cover roughly 3% of global surface area, they produce about 70% of carbon emissions.
