"Today, we all witnessed a historic decision to improve air quality in the capital city and protect ourselves from air pollution," Lamjav Byambasuren, vice health minister of the country, said at the opening of an event on raising public awareness of air pollution.

Public participation in air pollution reduction is important, Byambasuren said, calling on residents of the city to comply with the ban on the burning of low-grade coal for domestic use.

According to a statement issued by the National Committee for Environmental Pollution Reduction, households and enterprises who violate the ban will be fined from 300,000 Mongolian tugriks (over 113 U.S. dollars) to 3 million Mongolian tugriks (about 1,134 dollars).

Households in Ulan Bator will be supplied with processed fuel instead of raw coal.

Air pollution is one of the most pressing issues in Ulan Bator, which is home to around half of the country's 3.2-million population, and poses a major threat to the Mongolian people's health.

More than 800,000 residents, half of Ulan Bator's population, live in slums, also known as ger districts. They burn raw coal and other flammable materials to keep warm and cook during the six-month-long winter.

It is estimated that 80 percent of air pollution in the city is caused by ger stoves.

Since the early 2000s, the Mongolian government has carried out a number of measures aimed at reducing air pollution in Ulan Bator. However, the city has not seen a significant reduction in air pollution levels.
