Managing Environmental Impact

Environmental indicators:

• Year‑on‑year Increase in waste generation by 3.6% from 92,100 tonnes to 95,500 tonnes
• Reduction of air emissions by 5.9% from 3,400 tonnes to 3,200 tonnes
• Increase in water consumption by 2.1% from 4.6 million m³ to 4.7 million m³
• Increase in water discharge by 6% from 3.1 million m³ to 3.5 million m³.

There are no environmental fines in 2024.

The Company prevents environmental contamination and maintains an adequate level of sanitation at rail infrastructure by acquiring only carriages equipped with environmentally friendly toilet facilities. Such toilet facilities are installed during the overhaul of carriages.

Hazardous waste handling

In total, the Company generated 95,500 tonnes of waste of I–V hazard classes in 2024, up 3.6% year‑on‑year. The waste generation was driven up by the growth of passenger turnover, as well as the scheduled repairs and maintenance of carriages.

In order to reduce waste generation, the Company implements separate waste collection, isolating recyclable materials and sending them for recycling.

Air protection and climate impact

Total air emissions by the Company in 2024 amounted to 3,200 tonnes.

In the reporting year, the Company's gross air emissions totalled 3,200 tonnes, down 200 tonnes year‑on‑year.

The main measures for reduction of air emissions in the Company are:

• Gasification of boiler houses
• Construction of high‑voltage heating points for passenger carriages at the turnaround and originating stations
• Reduction of coal and fuel oil consumption.

Between 2019 and 2024, work was completed on 18 high‑voltage heating points with 55 high‑voltage charging points.

Sustainable water use

In order to reduce the amount of wastewater that may have a negative impact on the environment and operation of centralised sewage systems, the Company implements programmes for retrofitting treatment facilities and carriage washing facilities by furnishing them with a closed‑loop water supply system and local treatment facilities.

In particular, the following works are underway:

• Retrofitting carriage‑washing facilities with recycling water supply systems
• Upgrading water supply and sewer networks
• Revamping treatment facilities
• Retrofitting the buildings and structures with water metering units (consumption and discharge).

Utility consumption

To improve energy efficiency and reduce the energy intensity of its operations, the Company takes ongoing efforts to restrict its fuel and energy consumption. In 2024, the following activities were developed and implemented in this area:

• Purchasing new, advanced and energy‑efficient rolling stock
• Using energy‑saving technologies in the depot and station lighting systems (LEDs and smart control systems)
• Upgrading and converting boilers from liquid fuels to gas
• Retrofitting the Company’s buildings and structures with water consumption and discharge, electricity and heat meters
• Installing high‑voltage charging points at passenger train preparation sites
