Comparision of Air Pollution among the World Countries

ABSTRACT

The carbon emission, nitrous oxide emission and methane emission are the major components of air pollution. The largest carbon emitting countries in the world were China, United States, India followed by Iron, Saudi Arabia, South Korea, Canada, Mexico, Indonesia, Brazil, South Africa and Turkey. China alone emitted 9839 metric tonnes in 2017. The share of the above emission was 27.2 percentage in the carbon emission of world countries. United states were the second important country in emitting the carbon which accounted for 14.6 percentage in the total world countries emission. India emitted 2467 metric tonnes of carbon emission which accounted for 6.8 percentage in the total emission. China emitted double the emissions of United States and India. The top fifteen countries collectively such as China, United States, India, Iron, Saudi Arabia, South Korea, Canada, Mexico, Indonesia, Brazil, South Africa and Turkey emitted 72 percentage of carbon emissions the rest of the 180 countries in the world emitted nearly 28 percentage of the total global emission. It is close to the emissions of China. The nitrous oxide emission is yet another component of greenhouse gas. In 2018, the largest nitrous oxide emission was observed in the coal fixed power plants in South Africa, Germany and India and in coal burning industrial clusters in India. In India, the largest nitrous oxide emissions were observed at Delhi, Uttar Pradesh and in Odisha. The third important component of air pollution was PM10. The top countries emitting particulate matter were China, Spain, India, Chad, Mali, Nepal, Mexico, Israel, Uganda, Thailand and Turkey.Methane was the next important component of air pollution. Methane would stay about for about 9 years in the atmosphere. Therefore, methane had identified as the target for greenhouse gas emission. In this backdrop, an attempt was made to compare the air pollution among the world countries. The findings of the study showed that Bangladesh was the high air polluting country among the least developed countries. Among the developed countries, the problem of air pollution was predominant in United States. India was the highest air polluted countries among the developing countries. The estimated t value reveals that the carbon emission was significantly higher in developing countries than in less developed countries and between least developed and developed countries.
