City officials in Los Angeles are on a quest to reduce the effects of climate change by painting some of its streets in a light-colored, heat-reducing sealcoat, wrote dailymail.co.uk.

The product, called CoolSeal, is a 'water-based asphalt emulsion sealcoat designed to reduce surface temperatures and help mitigate heat islands,' the company website, GuardTop states.

The plan to reduce the temperatures was initially proposed early last year after the city experienced its hottest summer in 2016 - the year also said to be the warmest summer globally, according to the Los Angeles Times.

Los Angeles Mayor Eric Garcetti said in a statement the city has a goal to complete the pricey project over a 20-year period.

He said over that period, there will be a reduction in 'the average temperature in the metropolis by 3 degrees,' the LA Times says.

The sealcoat is costing the city roughly $40,000 per 1.6 km.

With rising temperatures predicted to keep occurring, the measures could be also be crucial to prevent heat exhaustion, heat stroke and heat-related fatalities.

While the concept of cool pavements has been around for years, a project of this kind has not been completed.

Some questioned whether the greenhouse gases involved in the manufacture and procedure of laying the sealant could do more harm than good on the environment.
