Glaeser and Kahn found that carbon emissions per person were lower in denser urban areas with taller buildings. This is because in cities people rely more on public transportation and live in smaller living spaces, which results in lower energy consumption. Therefore, building more and taller skyscrapers in cities could be an effective way to reduce carbon emissions.
