Sustainable City

Here's your chance not just to be the mayor, but the original city planner as well! Imagine a medium sized city that would be developed with modern, low carbon transportation in mind, and other strategies to reduce the average citizens' carbon footprints.

What would that city look like? Would that make you more likely to want to live there?

The albedo of my city

I would paint the roads white because this raises the albedo of the roads. By having a higher albedo, the temperature of the city would be cooler. Los Angeles is already doing this, having started in 2017, which will hopefully lower the temperature of the city by 3 degrees in 20 years. https://www.popsci.com/la-is-painting-i … city-cool/. My city would also have parking garages, so there is less roadside parking. Without the need for roadside parking, the roads can be narrower. This means that there is more space for trees and grass, which both have a higher albedo than asphalt or concrete.

I agree on painting roads white, as well as painting the roofs of buildings white. This would be great for decreasing the temperature in our cities, as well as having parking garages available for public use. Having more room for grass and trees in cities would help raise the albedo but also would reduce carbon emissions.
