California's Gov. Gavin Newsom signed an executive order last week to achieve more than a 35 percent reduction in greenhouse gas emissions. The order mandates 100 percent of new passenger cars and trucks sold in California are zero-emissions by 2035. "It’s an aggressive move to tackle the greatest source of greenhouse gas emissions in the state as well as the US at large," Gizmodo reports. "The state accounts for a shocking 1% of entire global oil demand and is the second-biggest state consumer of gas in the US after Texas."
