Discussions about reducing CO2 emissions often have a dismal tone, saying that we can’t reduce emissions without a drastic reduction in living standards. Sometimes the inference is that we should do nothing, other times that we should embrace drastically lower living standards (but probably won’t). Most people share this intuition to some extent, particularly as regards activities like driving, that seem central to a modern lifestyle. So, it’s striking to see what’s been happening to per capita gasoline consumption in the US
There’s a lot going on here: prices, fuel economy regulations, ethanol and general cultural shifts which have reduced distances driven. But the big point is that this drastic decline has happened with only modest policy measures, and without any obvious impact on living standards (US living standards haven’t done well in the 2000s, but for entirely different reasons). Looking ahead, Obama’s fuel economy regulations and sustained high prices should drive US gasoline consumption much lower.
