In Tashkent, the issuance of stickers based on vehicle emissions levels has begun.

In the capital of Uzbekistan, the implementation of a new system has begun, which will assign environmental stickers to vehicles, categorizing them into three groups: "clean" (green), "moderate" (yellow), and "harmful" (red). These stickers will be mandatory for the registration and re-registration of vehicles. The ecological class of each car will be determined automatically, based on factory standards of "Euro" or the results of a free diagnostic check. This labeling will play a key role in access to special "clean" zones, the boundaries of which will be defined by local Councils in the near future. The most discussed issue will be territorial zoning, as owners of cars with a low eco-class may be prohibited from entering these areas or allowed only upon payment of the corresponding fee.

Such measures are part of a global trend and have been successfully implemented in major cities in Europe for nearly 30 years. A striking example is London's ultra-low emission zone (ULEZ), which covers all of Greater London, including Heathrow Airport, over an area of about 1,600 square kilometers. In London, the right to free passage is granted to petrol vehicles meeting Euro 4 standards and above (mostly those produced after 2005) and diesel vehicles with a standard of no less than Euro 6. Those who do not meet the environmental requirements will have to pay a daily fee of £12.50 for cars and £100 for trucks and buses. Thus, the Tashkent initiative effectively adapts international experience, creating a legal framework for improving air quality in the city through economic and administrative measures.
