In introducing his bold, comprehensive plan for a sustainable New York on Earth Day, Mayor Michael Bloomberg pointed to research showing that New Yorkers already had the lowest per capita carbon emissions in the nation. While most news outlets focused on the controversial idea of congestion pricing for Manhattan below 86th Street, they missed the larger point: Well-planned urbanism is likely to be our best hope for curbing greenhouse gas emissions and cutting oil dependency. Sheryl Eisenberg, a New Yorker who blogs for the Natural Resources Defense Council, explains: “The primary reason is … population density. First, it makes a truly comprehensive public transit system possible. Second, it makes walking and biking emissions-free modes of transportation viable. And third, it keeps home energy use down,” because New Yorkers live in smaller-than-average dwellings, and shared walls are more efficient.”
