Photos help them to find out which factories work properly if they are only white smoke emitted but if the pollution crosses limits than black, purple or brown smoke will come out of the chimneys. The Ministry first introduced four drones in 2012, they have been helped the country to address a plethora of environment issues. The Ministry is also considering use of drones to shoot chemical into air and freeze the pollutants during peak air pollution periods. The drones which have the capacity to carry about 180 pounds of haze-scrubbing chemicals but in near future they could care more than 1500 pounds. The UAV which comes with a gliding parachute can make a 2 hour journey at a time, covering about 70 sq km.

Deploying these drones is apparently a 90% cheaper than using a fixed wing aircrafts to spray the chemicals. A major problem Environmental degradation  and pollution have become a major concern of China and it is an issue that can no longer be ignored. China is also aiming at lowering the energy consumption and minimizing vehicle exhaust fumes closing down may coal furnaces to reduce the pollution.

In order to mask pollution and smoke, China has been using rockets and artilleries to disperse chemicals like silver iodide into sky. The method also known as “cloud seeding” which helps to bring rain and clearing the sky. At present these drones are doing a great job in this war against heavy air pollution.
