Rapid increase in the number of cars is deteriorating the air quality, according to Bhutan State of the Environment Report 2016. The report says increasing vehicle population adds greenhouse gas emission in the air.
Over 1,000 grams of greenhouse gas are emitted with over 28 cars hitting the road every day. Rubbers from worn-out tires and brakes add to the contamination.
National Environment Commission’s Tshewang Dorji said vehicle emission contributes a lot to the air pollution because vehicle emission contains both particulate and gaseous material.
He said gaseous material when in the atmosphere undergoes some chemical reaction forming a substance that is not desirable.
“When you live in places with high pollution, it becomes difficult for young and adult, especially those with asthma.”
Despite increase in number of vehicle, re-suspended road dust from unpaved roads industrial and mines activities, forest fires and trans-boundary pollution contributes to air pollution in the country.
