New research shows that improving the reflectivity of urban roofs and road surfaces may reduce the temperature of the earth's atmosphere at a very low cost  Although the reduction is small, it can be measured  Because roofs and roads account for more than 60% of the city's surface area, the use of light-colored materials can increase the average reflectivity to a certain extent, reducing the global average temperature by as much as 0
07 degrees Celsius, according to researchers in the Environmental Research report
The new material can greatly reduce the indoor temperature
