      Density reduces emissions

      I reply to your infographic with a scientific paper that shows higher densities lead to higher CO2 emissions: https://www.mdpi.com/2073-4433/12/9/1193#:~:text=Regarding CO2 emissions%2C the,density%2C the higher the emissions.

      This study was done in Spain.

      Another study, in Nature, also shows that lower density is better for reducing carbon emissions and climate change. https://www.nature.com/articles/s42949-021-00034-w

      Sorry, but you and your infographic/sources are not supported by science.

        Literally the frist sentence in the abstract:

        More than 50% of the world’s population lives in cities. Its buildings consume more than a third of the energy and generate 40% of the emissions.

        “higher densities lead to higher CO2 emissions” you say…

        The low density/low height example in the nature article is still 5k people per Km^2. While definitions vary wildly, I usually see 1000-400 people per km^2 for suburb definitions.

        Does example D look like suburbs to you? As something undefined it could be considered suburbs, but probably “streetcar suburb” in the Canadian/American context.

        Critically the article also mentions a requirement for best practice greenery management to maximize carbon sequestration. I’m no botanist, but I’m guessing caretaken parks do better then monoculture lawns (assumption).
