Cities and CO2: Two Views of Greenhouse Gas Emissions

The slide from the Center for Neighborhood Technology shows how dense cities are commonly viewed as areas of concentrated CO2 emissions (when emissions are viewed on a per-square-mile basis) but are actually extremely low producers of such emissions when viewed on a per capita (or per household) basis. Specifically, the average exurban household in a sprawling Chicago exurb generates about 11.5 tons of C02 per year, but those in suburban areas served by commuter rail generate 23% less C02 with their cars, or about 9 tons on average. By moving to a city neighborhood -- or a compact, mixed-use rail-connected suburb such as Evanston or Oak Park -- a household would expect to see their auto-generated C02 drop precipitously to about 2.5 tons per year. They'd be switching to transit for some trips, which involves some generation of greenhouse gases, but at a far, far reduced rate. And more destinations would be within walking and biking distance too.
