Sometimes the answers are really simple. Defecting heat on streets is a great compliment to the same practice, in place for years, on rooftops.
You wonder if there's additional visibility and safety improvements as an added bonus to the lighter color?
Los Angeles painting city streets white in bid to combat climate change
California officials are hoping their latest attempt to stem the rising tides of climate change leads to a more socially conscious -- and cooler -- summer.
Officials in Los Angeles have been painting streets white to reduce the effect of urban "heat islands" and combat the effects of climate change.
"CoolSeal is applied like conventional sealcoats to asphalt surfaces to protect and maintain the quality and longevity of the surface," according to the company website. "While most cool pavements on the market are polymer based, CoolSeal is a water-based, asphalt emulsion."
While each coasting could can last up to seven years, they are also pricey, with the estimated cost of $40,000 per mile, the L.A. Daily News reported.
By reducing the temperature of the city streets, officials say it can help reduce temperatures in the neighborhoods where the sealant is applied.
With its numerous streets and freeways, Los Angeles suffers from the "heat island" effect, which causes urban regions to become warmer than their rural surroundings, forming an "island" of higher temperatures.
Los Angeles Mayor Eric Garcetti, who may make a run for president in 2020, has used the project as part of an overall plan to reduce greenhouse gas emissions in the city by 45 percent below 1990 levels by 2025.
"Climate change is a fact of life that people in Los Angeles and cities around the world live with every day. It is a grave threat to our health, our environment, and our economy — and it is not debatable or negotiable," he said in a statement last year after President Trump said he would walk away from the Paris Climate Agreement.
