“California and New York have recently set some of the world’s most ambitious climate targets, aiming to slash their net emissions of planet-warming greenhouse gases down to nearly zero in just three short decades.
Now the race is on to see if either state can pull off this feat — something that no major economy in the world has yet achieved. For now, neither state has a clear advantage, and both must overcome unique obstacles to clean up their power plants, cars and buildings. New York has the lowest per-person emissions of any state in the nation, but California is close behind.”
