Air pollution in Indonesia

Indonesia is the fourth most populous country in the world.
During the 1980s and 1990s, Indonesia experienced significant environmental degradation due to the increasing population.

Air pollution is Indonesia's most serious environmental problem.
Motor vehicles are one of the main sources of air pollution in Indonesia especially in Jakarta.
Forest fires also contribute to air pollution in Indonesia. These fires were resulted from illegal logging of Indonesia's rain forests. Nearly 10 million hectares were burned, producing a haze that impacted the neighboring countries like Singapore and Malaysia.
Other sources of pollution are Indonesia’s industrial sector. They release dangerous chemicals into the atmosphere.

To control the air pollution in Indonesia, The Blue Sky Program was initiated by the government to improve air quality in Indonesia's five largest cities: Jakarta, Bandung, Semarang, Surabaya, and Medan.
