Back in 2006, California set strict targets to reduce its greenhouse gas emissions. The state would have to reset its emissions to 1990 levels by 2020, representing an overall 25 percent reduction. This wasn’t just a nebulous goal but a legal mandate, as the target was codified into state law.
But the Golden State doesn’t have to worry about missing that deadline, because it already achieved its 2020 goal — four years early.
State officials reported that emissions dropped to 429 million metric tons in 2016, a figure slightly lower than the 431 million metric tons produced in 1990. That means California has already beat its 2020 goal, which is roughly the equivalent of taking 12 million cars off the road.
