Winters in Mongolia are miserably cold. Its capital, Ulan Bator, home to nearly 1.5 million residents, is the world’s coldest capital city. Temperatures remain well below freezing for weeks at a time, making staying warm a matter of survival. To heat their gers, or yurts, the predominantly lower- to middle-income migrant workers who live in unplanned districts on the north of the city burn coal. Lots of it. In recent years, they’ve been burning over a million tons of raw coal per year. And those who can’t afford coal often burn garbage, adding plastics and other pollutants. As a result, #UlanBator has become the capital city with the highest recorded levels of air pollution, surpassing notoriously polluted megacities like Beijing and New Delhi. To improve the city’s air quality, Prime Minister Ukhnaagiin Khurelsukh announced in January that the transportation and use of raw coal in Ulan Bator would be banned starting next April. But many are skeptical that Mongolia’s government will be able to enforce the ban. “It’s a fairy tale,” said Khangai Unurkhaan, who sells raw coal by the truckload near the city center. “There are thousands of families who mine, sell and burn coal in order to live,” he added before leaving to deliver a 1.3-ton load of coal, which at $65 to $75 lasts a family about one month, according to official estimates. @bdentonphoto took this photo of a group preparing for an ice archery competition on the frozen Tuul River, which runs through Ulan Bator.
