On February 22, the operations of Tashkent TPP were studied by a working group comprising representatives from the Ecological Party, the Ministry of Ecology, Environmental Protection, and Climate Change, the Prosecutor General's Office, and deputies from the Legislative Chamber of the Oliy Majlis. The group's findings established the power station as a source of pollutants contributing to the degradation of air quality in the city of Tashkent.

It was revealed that Tashkent TPP has been using mazut to prevent outages in electricity and heat, raising concerns about environmental pollution due to obsolete equipment and a lack of technology to curtail harmful emissions into the atmosphere.

Drawing from their findings, the working group proposed the following recommendations:

- Implement automatic systems at the plant for sampling and analyzing emissions released into the atmosphere.
- Install filters on station pipes to reduce air-polluting substances.
- Set up stationary monitoring posts to determine the level of atmospheric air pollution.
- Carry out capital repairs on the primary purification pools for oil-contaminated waters at the station due to their obsolescence.

Officials have requested that the Ministry of Energy ensure the recommendations are incorporated into the operational processes of the Tashkent TPP Joint Stock Company.

Furthermore, a parliamentary inquiry has also been sent to the Prosecutor General's Office, the Ministry of Energy, the Ministry of Ecology, Environmental Protection and Climate Change, and the government, calling for substantiated explanations and presentation of their points of view on the matter. Additionally, the party emphasized ongoing public monitoring and raising awareness among the broader community.

It is noteworthy that during a parliamentary meeting on January 30, Ecology Minister Aziz Abduhakimov reported on air pollution, stating that coal and mazut contribute to 20 percent of PM2.5 particulate matter. On February 14, the Ministry of Energy refuted this, claiming that emissions from the station never exceed prescribed standards. Nonetheless, on February 21, Tashkent once again topped the list of cities with the most polluted air.
