Atmospheric Air Protection
The Gazprom Group takes comprehensive efforts to reduce pollutant emissions from hydrocarbon production, processing, underground storage and transportation. Emissions monitoring is part of its corporate environmental management system, which aligns with the provisions of the Russian Energy Strategy through 2030 and the Russian Ecological Doctrine.
Significant environmental aspects of PJSC Gazprom entities’ emissions management:
- Methane emissions associated with trunkline repairs;
- nitrogen oxide emissions during compressor station operation.
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. It seeks to ensure compliance with statutory environmental requirements and 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.
Gazprom Pererabotka launched into operation a predictive pollutant emission monitoring system facilitating continuous automatic measurement of mass concentration of air pollutants in the residue gases, control of physical gas flow properties, conversion of measurement results and automatic data transfer to the Rosprirodnadzor information system.
In addition to the pollutant compliance monitoring, it provides additional data for control and optimisation of technological processes, which can be used for reducing pollutant emissions.
PJSC Gazprom entities’ share in total gas business emissions exceeds 91% and defines the overall trend of this indicator.
The majority of Gazprom Group emissions is represented by hydrocarbons, including methane, carbon oxide, nitrogen oxides, and sulphur dioxide in line with the production activities of PJSC Gazprom entities and other gas business companies. Solid emissions come mostly from Gazprom Neft as a result of APG flaring and PJSC Gazprom’s energy segment, while volatile organic compounds are commonly associated with Gazprom Neft and gas business companies.

Every year, PJSC Gazprom subsidiaries and entities take numerous steps to reduce pollutant emissions. Energy-saving projects leveraging cutting-edge technologies to save gas during repairs on the linear part of gas trunklines play an important role in cutting emissions.
Gas production subsidiaries conduct well surveys using telemetry without releasing natural gas into the air and make use of concentric tubing and multi-component surfactant compositions to better remove reservoir fluids from well bottomholes, which helps reduce gas emissions. To cut down on its nitrogen oxide emissions, Gazprom applies selective catalytic reduction of nitrogen oxides from waste gases.
To reduce nitrogen oxide emissions, PJSC Gazprom is implementing a programme to equip gas pumping units with low-emission firing chambers, which bring down the reduce combustion temperature without using water, reducing air emissions.
APG Flaring Reduction
Since 2011, Gazprom has been working to utilize associated petroleum gas more efficiently even as hydrocarbon production grows. This helps cut GHG and pollutant emissions and moves the Group closer to the legally required APG utilization rate of at least 95%Set by the Russian Government’s Decree No. 1148 dated November 8, 2012.. 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 2025, the Group’s APG utilization rate reached 96.5%, against a 1.4 bcm increase in APG production from 2024 (to 28.7 bcm).
Measures to minimize APG flaring in the reporting year included:
- maintaining the reliability of gas equipment (ensuring a high operating factor);
- continuously aligning planned oil and gas infrastructure works, including with receiving parties’ repairs;
- commissioning low‑pressure gas compressors at the Vyngayakhinskoye and Orekhovo‑Yermakovskoye fields;
- increasing compressor‑free gas supplies to SIBUR Holding using additional APG;
- commencing APG supply from the Urengoyskoye oil and gas condensate field under long‑term risk service agreements on schedule.
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 2018–2020.
| Indicator | 2023 | 2024 | 2025 | Change 2025/2024 |
|---|---|---|---|---|
| APG utilization, % | 94.7 | 96.1 | 96.5 | +0.4 p.p. |
| APG flaring across the Gazprom Group, mcm | 1,588.2 | 1,276.2 | 1,173.2 | –8% |
The 2.2 bcm increase in APG utilization over the target resulted from higher gas extraction and processing, a high operating factor, and continuous alignment of planned oil and gas infrastructure works, including with the receiving party’s repairs.
Gazprom Neft designed and put into commercial operation a unit to convert APG to useful fractions. The solution is set to decrease the company’s environmental footprint by making APG treatment more efficient as a single unit will annually extract up to 5,200 tons of stable gas condensate from APG and cut СО2 emissions at oil and gas treatment facilities by 7%.
