The average citizen in New York City emits a third of the carbon per capita of the rest of the country, so it’s easier to have less impact in the city than it is in the suburbs. Having said that, there’s things that are easier depending on what city you’re in. For example, we find it’s easy to get rid of the car and bike everywhere, but that would be more challenging in, say, L.A. On the other hand, many people in L.A. have gardens, so they could actually be growing some of their own food.
