Brad Plumer at Vox anaylzes the data to show that if, for example, the city of San Francisco built housing to accommodate 10,000 current Bay Area residents (i.e. those living in more wasteful, suburban environments), the city could save 79,000 metric tons of CO2 per year, three times the amount of CO2 that the solar panel legislation could save.

If this was applied to the U.S., Plumer reasons, the effect could be tremendous, although decreasing housing costs, along with increasing supply, would be the only way to ensure that green (or green-er) city living is available to a broad range of individuals.
