Urban Sprawl, Cars Hamper Cities’ Best Efforts on CO2
There’s no way to drive around it: Commuting to work behind the steering wheel emits carbon dioxide and contributes to climate change.
Dense cities are pretty good at keeping those tailpipe emissions low when measured on a per-person basis because many commuters often use trains and buses to get to work. Less dense cities, on the other hand, see more people driving to work from distant suburbs, usually leading to more tailpipe emissions.
