Environmental Impact Prevention

In accordance with Russian laws, Gazprom Group entities conduct environmental impact assessments (EIA) of planned business activities at all stages of the investment project life cycle: from planning to commissioning.

As part of the expert review, PJSC Gazprom conducts a comprehensive assessment, in particular, to ensure that documentation complies with Russian laws, international standards and rules, and PJSC Gazprom’s regulations and guidelines in environmental protection and energy efficiency.

To improve the quality of documentation regarding the adoption of modern environmental protection and energy-efficient solutions, all PJSC Gazprom’s investment projects are subject to expert review in the field of environmental protection and energy saving.

Compliance with technical solutions and environmental protection requirements is monitored by construction monitoring services, and the implementation of design solutions is subject to design supervision.

At the corporate level, PJSC Gazprom has an Environmental Inspectorate in place. In addition to monitoring compliance by subsidiaries and contractors with environmental laws, corporate standards, and rules relating to environmental protection and energy saving, it conducts internal EMS audits of PJSC Gazprom’s subsidiaries and entities.

The Environmental Inspectorate’s activities are aimed at improving environmental protection and ensuring environmental safety at Gazprom Group facilities.

Priority measures include:

• enhancing the efficiency of the corporate environmental control system;
• organizing and conducting internal EMS audits combined with verifying compliance with environmental laws by subsidiaries and entities within the scope and boundaries of PJSC Gazprom’s EMS;
• other control and supervisory measures to ensure compliance with laws, corporate standards, and rules relating to environmental protection and environmental safety at Gazprom Group facilities;
• organizing control over compliance with requirements during operational environmental (including eco-analytical) monitoring at PJSC Gazprom’s subsidiaries;
• analyzing the practice of interactions between PJSC Gazprom’s subsidiaries and entities and state control (supervision) bodies to eliminate and prevent violations of environmental laws;
• monitoring compliance with environmental design solutions during the construction and reconstruction of Unified Gas Supply System (UGSS) facilities.

Gazprom’s Operational Environmental Monitoring (OEM) system includes fixed-site and mobile environmental laboratories, meteorological and hydrological stations, automated air pollutant emission monitoring stations, and observation wells. This enables monitoring of:

• air pollutant emissions from organized sources;
• atmospheric air quality in localities and at the boundaries of sanitary protection zones around production facilities;
• noise impact;
• radiation background;
• surface and groundwater quality, bed sediments;
• water sources for utility and drinking purposes;
• state of the geological environment, soil and snow cover;
• waste and effluents.

The system includes monitoring of environmental parameters, analysis of results, and development of measures aimed at minimizing negative environmental impact.

24/7 monitoring systems are operated to detect methane in ambient air and provide automatic alarms for excess concentration; remote laser methane detectors are also used. Methane detection at gas industry facilities is also handled using detectors installed on helicopters. The Company takes steps to introduce modern methods for satellite-based monitoring of GHG emissions, particularly methane.

The Company is developing services relying on aerospace data and artificial intelligence, which expands capabilities for regular environmental monitoring in the Russian Far North regions. The use of neural networks will accelerate the analysis of aerospace imagery, enhance the detail of digital cartographic models, and introduce new functions.

The OEM system enables Gazprom to promptly receive reliable information on the state of environmental parameters in the areas affected by the Company’s production facilities, timely analyze the environmental conditions when conducting business operations, plan environmental protection measures, monitor their implementation and make informed management decisions in this area.

In exercising OEM at production facilities, Gazprom makes active use of mobile environmental laboratories that have cutting-edge analytical equipment to monitor atmospheric air, physical environmental factors, meteorological parameters, as well as industrial emissions from various sources. Photos and videos captured during visual aerial surveys have significantly improved control effectiveness, reduced inspection time, and decreased vehicle mileage – an especially important benefit in hard-to-reach areas.

As part of the import substitution policy, only domestic laboratory equipment is procured.

Some of Gazprom’s OEM systems are integrated with regional environmental monitoring systems.

The Group’s OEM programs provide for the environmental monitoring of designated conservation areas or sites with a special environmental status located on the territories affected by the Group’s activities.

In 2025, state supervisory bodies conducted 989 compliance inspections for environmental protection and natural resource management at Gazprom Group facilities, revealing 553 violations, whereas 727 inspections identified no breaches of environmental requirements.

Out of the 553 breaches identified in 2025, 33 breaches (6.0%) were overturned by courts of law or otherwise, 66 (11.9%) are being contested, 271 (49.0%) were remedied in due time, and the period for remedying 159 (28.8%) did not expire in the reporting year. In total, 271 violations were rectified during the year, including 123 violations identified by previous years’ inspections.
