This article analyzes the level of air pollution in Uzbekistan, its main
sources, as well as the reforms being implemented by the state to ensure environmental safety,
strategic documents, and priority goals.
Keywords:
environmental safety, atmospheric air, pollution, motor transport, fuel quality,
national strategy, air monitoring.
Introduction.
Serious attention is also paid to the problem of environmental safety in
Uzbekistan. Because in 2019, the amount of atmospheric air pollutants in the republic amounted
to more than 2.5 million tons, of which more than 65% was accounted for by road transport,
which is 3 times higher than the established norms for the level of atmospheric air pollution in
developed countries. In addition, due to the climatic features of the territory of the republic over
the past 10 years, the appearance of a background of constant air pollution with dust particles in
the zone of human breathing is characteristic (Fig. 1).
Effective work is being carried out at the government level to solve this
problem. Relevant strategic documents have been developed that define goals in the field of
combating air pollution and improving its quality. The National Action Plan for Environmental
Protection and Health, the Strategy for the Sustainable Development of Work to Reduce the
Share of Harmful Emissions from Road Transport into the Atmosphere, are being systematically
implemented [1-3]. These strategic documents define the following main goals: reducing air
pollution from transport and other mobile energy sources; improving the quality of various types
of motor fuels; modernizing and replacing old vehicles, including trucks; improving the road
network in large cities and other regions; stopping the production of leaded gasoline, wider and
subsequent full use of natural gas as motor fuel; increasing the role of technical inspections and
strengthening control over emission norms and standards, as well as improving the activities of
vehicle repair services for state and private vehicles; introducing state monitoring of the state of
air pollution of the natural environment, including in the surface layer of the atmosphere and
sources of pollutant emissions [4].
Result and discussion.
Motor fuels produced in the republic must also comply with
Euro-3 environmental standards, in particular, the sulfur content in diesel fuel should not exceed
0.035%. However, the fuel produced today only meets Euro-2 environmental standards.

Average components of atmospheric air pollution by harmful substances in the republic:
- road transport;
- dust film in the atmosphere;
- industrial production.
According to the draft resolution of the Cabinet of Ministers of the Republic of
Uzbekistan "On Strengthening Environmental Protection Measures in the Context of Reducing
the Amount of Pollutants Released from Motor Vehicles," developed by JSC "Uzavtosanoat," by
December 1, 2014, the production and supply to the domestic market of motor vehicles meeting
the requirements of the environmental class "Euro-3" are envisaged.
To increase the environmental efficiency of manufactured vehicles and limit the amount of
pollutants, national standards have been developed:
O'zDst - 35.49.11 "Unified Provisions on Measures to Control the Amount of Pollutant
Gas and Particles from Gasoline Engines Intended for Use in Automobiles, as well as the
Emission of Gaseous Pollutants from Clare Engines. Fire Extinguishing Designed for Use in
Vehicles Operating on Natural Gas or Liquefied Petroleum Gas" (UNECE Regulation No. 49 ed.
4 (document E/ECE/324-E/ECE/TRANS/505/Rev.1/Add.48). / Rev.4, August 13, 2008);
-O'zDst -35.83.11 "Unified Rules for the Approval of Motor Vehicles by the Quantity of
Pollutants Released from Engines Depending on the Quality of Fuel" (identical to the UNECE
Charter: Revision 3 (E / ECE / 324 -) E / ECE / TRANS / 505 / Rev.1 / Add.82 / Rev.3, June 14,
2005).
-Phased abolition of fuels below Euro-4 has begun in Uzbekistan [12]
;
- From January 1, 2022, the import of motor fuel of the environmental class below Euro-3,
and from January 1, 2023, the import of motor fuel of the environmental class below Euro-4 is
prohibited.
This is stated in the presidential decree "On Approving the Concept of Environmental Protection
of the Republic of Uzbekistan until 2030" .
According to the document, it is planned to:
commissioning of new capacities for the production of motor fuel of an environmental
class below Euro-4 from January 1, 2020;
From January 1, 2022, the "temporary import" and "release for free circulation (import) "
of motor fuel of the environmental category below "Euro-3," and from January 1, 2023, the

import into the republic of motor fuel of the environmental category below "Euro-4" are
prohibited:
- the republic does not have a regulatory framework based on specific norms for sources
of pollutant emissions into the atmosphere; about 2% of the production and use of lead gasoline
continues, which does not allow the use of catalytic converters of exhaust gases. The experience
of developed foreign countries shows that their use allows for a reduction in pollutant emissions
by more than 50%;
- to date, the production of diesel fuel with a sulfur content of 1.2% continues, which
ultimately leads not only to premature engine wear but also to a high content of pollutants in the
exhaust gases of vehicles.
Today, the European Union sets the next task of strengthening environmental
requirements for road transport, that is, the complete elimination of harmful emissions from road
transport by 2050, for which new rules, standards, and new sanctions are being introduced.
1. When using fuel that meets EURO requirements instead of standard locally
produced fuel, the amount of harmful emissions by average weight decreases by 10-12%.
2.
In 2019, the volume of harmful emissions in Uzbekistan amounted to 2.5 million
tons, of which the share of road transport is more than 65%. The amount of pollutants emitted by
vehicles remains unchanged year by year. The Government of Uzbekistan is implementing
effective programs to reduce air pollution by harmful emissions from road transport.
