I suspect it's more about wealth, people in cities earn and spend more. In general the more you spend the bigger your carbon footprint.

I think in the statistic you cite, 'city' includes both the urban part and the sprawling suburbs. You'd also want to compare apples to apples: someone living a very green life in a "western" city is still likely to live a more carbon-intensive life than someone doing subsistence farming.
