Atmospheric Air Protection
Emissions monitoring is part of its corporate environmental protection strategy, which reflects provisions of the Russian Energy Strategy through 2030 and the Russian Ecological Doctrine.
Impact mitigation targets are in place for each type of operations. In the reporting year, the Group analyzed and identified significant environmental aspects requiring special attention.
Significant environmental aspects of PJSC Gazprom's emissions management
- Methane emissions associated with trunkline repairs;
- nitrogen oxide emissions during compressor station operation.
The Gazprom Group takes steps to reduce pollutant emissions by relying on mobile compressor stations to pump gas, using hot tapping, and blowing gas from the sections under repairs into neighboring active pipelines. Gas production facilities conduct well surveys without releasing natural gas into the air and make use of multi-component surfactant compositions to better remove reservoir fluids from well bottom holes, which helps reduce gas emissions into the air. To cut down on its nitrogen oxide emissions, PJSC Gazprom applies selective catalytic reduction of nitrogen oxides from waste gases.
Air pollutant emissions are controlled using an operational environmental monitoring and control (OEMC) system. The Group introduced operational environmental control at facilities with a negative environmental impact (categories 1–3) across all its entities. The initiative seeks to ensure compliance with statutory environmental requirements and environmental impact standards, as well as the sustainable use of natural resources. Operational environmental control procedures are applicable to all production stages at PJSC Gazprom's subsidiaries, entities, and contractor companies and are a key tool to reduce the Group's environmental footprint.
For more details on the Gazprom Group’s efforts to monitor methane leaks, see the Reduction of Methane Emissions subsection.
In 2024, the Group's gross pollutant emissions from stationary sources went slightly up year-on-year (by 6.7%) to 2,362,350 tons due to an increase in hydrogen production and gas transportation.
Units for capture and treatment of waste gases processed 203,570 tons of harmful emissions. Gazprom Energoholding, PJSC Gazprom entities and other Group entities had 192,130 tons, 5,060 tons and 6,380 tons of pollutants captured and neutralized, respectively.
Captured and neutralized pollutants contain 96.6% of solid particles, primarily solid fuel ash from energy facilities.
A 4% reduction of emissions from Gazprom Energoholding is due to coal replaced by natural gas in the fuel mix and an effective energy saving program. A 20% year-on-year increase in Gazprom Neft's gross emissions comes as a result of growth in hydrocarbon production and updated process parameters of flaring units..
Pollutant emissions from stationary sources of the Group's gas business companies went up 4% year-on-year to 1,617,800 tons. PJSC Gazprom entities' share in total gas business emissions exceeds 90% and defines the overall trend of this indicator.

APG Flaring Reduction
The Gazprom Group is working to reduce APG flaring and related GHG and pollutant emissions to progress towards its corporate target in this area. The Gazprom Group’s investment projects make a contribution to this goal as they provide for the transportation and supply of APG to gas processing plants and the UGSS of the Russian Federation, APG processing, generation of heat and electricity for the Gazprom Group’s internal needs, and APG injection into the gas cap to maintain reservoir pressure. In 2024, APG utilization across the Gazprom Group was 96.1%, an increase of 1.4 p.p.
APG utilization across the Gazprom Group’s assets in RussiaTaking into account production at fields operated by PJSC Gazprom or its core subsidiaries and entities under subsoil use licenses and developed by Gazpromneft-Zapolyarye in accordance with long-term risk service agreements signed in 201 8–2 020.
| Indicator | 2022 | 2023 | 2024 | Change 2024/2023 % |
|---|---|---|---|---|
| APG utilization, % | 94.2 | 94.7 | 96.1 | + 1.4 p. p. |
| APG flaring across the Gazprom Group, mcm | 1,498.6 | 1,588.2 | 1,276.2 | – 19.6 % |
