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%20CO2%20emissions%2C%20the,density%2C%20the%20higher%20the%20emissions.

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).
