As shown in this California Air Resources Board (CARB) chart below, California’s actions designed to conform to SB375’s greenhouse gas (GHG) reduction requirement have been less than stellar. True there has been some lowering of the ultra-high levels that were occurring between 2000 and 2008, but this improvement resulted mostly from federal and State mandates imposed on automobile and truck manufacturers to improve engine efficiency.
But to get to where California needs to get will require much more than just that. In terms of reduced automobile and truck use, virtually no progress has been made and the Bay Area is no exception to this. As can be seen, in order to meet the 2030 and 2050 targets the pace of reducing car use and making other GHG-reducing changes must pick up significantly. So why have efforts to clear the roadways and reduce GHG emissions so far been so lethargic?
