A new World Bank report entitled “Air Quality Assessment for Tashkent and the Roadmap for Air Quality Management Improvement in Uzbekistan” gives a frightening assessment of the air quality in the country’s capital.
The report finds that ambient PM2.5 concentrations in Tashkent, which peak in winter, substantially exceed international air quality standards. The annual average concentration exceeds six times the WHO’s average yearly guideline of 5 µg/m3.
In Tashkent, PM2.5 ambient air pollution has considerable health and economic costs. It can be linked to health costs equivalent to 0.7% of Uzbekistan’s gross domestic product (GDP).
Most air quality-related diseases and premature deaths in Uzbekistan and worldwide are linked to PM2.5, which the World Health Organization (WHO) has identified as the pollutant with the gravest health risk. According to IQAir, Tashkent, like other Central Asian cities, frequently ranks among the world’s most polluted urban areas.
According to the report, the primary sources of human-caused PM2.5 pollution in Tashkent are the heating (28%), transport (16%), and industrial sectors (13%). Cross-boundary sources like windblown dust (36% PM2.5 pollution) dominate in the summer, while commercial and residential heating is the primary source of PM2.5 pollution in the winter.
The report’s AQM roadmap for Uzbekistan formulates priority actions such as updating air quality standards and legislation, developing a national AQM strategy and coordination mechanism, and taking measures in the industrial, transport, and heating sectors, which are most responsible for air pollution.
The AQM roadmap recommends investments in emission reduction measures. The roadmap suggests that emissions from the heating sector can be reduced by improving the quality of fuels used and the efficiency of heating appliances, implementing energy efficiency measures, and switching to cleaner heating alternatives.
At a government meeting on October 9, Uzbekistan’s President Shavkat Mirziyoyev reviewed a draft master plan for the city of Tashkent until 2045.
Today the population of Tashkent is more than 3 million people, and it keeps growing. Over the past ten years, the average air temperature in Tashkent has increased by 1 degree Celsius. The number of cars is rising, and traffic is becoming increasingly congested.
The new master plan takes these aspects into account. It plans to increase green areas in Tashkent and its suburbs threefold to 25,000 hectares, which will increase per capita green area from the current 3 to 6 square meters.
Mirziyoyev emphasized the need to turn Tashkent into a city where at least 7.5 million people can live and work.
