The city of Los Angeles will be testing out a layer of CoolSeal paint on public streets, which cuts down how much heat asphalt absorbs

Most of us know the feel of black asphalt on a hot summer’s day. That asphalt can also make the surrounding temperature even hotter because of how it absorbs and reflects sunlight, leading to increased use of air conditioning. The city of Los Angeles is implementing a new tool to help keep the city cooler and save on energy: paint.

The city is looking to cover its streets with a layer of grey CoolSeal paint, which has been shown to help reduce temperatures by up to 10 degrees Fahrenheit. Produced by California-based GuardTop, the city will first test the paint on sections of public road, in order to gauge how long it takes for the paint to wear off in regular traffic and to see if residents can feel the difference in temperature. However, this paint only treats the symptom rather than the cause, as global temperatures continue to rise and affect cities near and far.
