Gazprom operates both in densely-populated Russian regions and in pristine areas across Eastern Siberia, the Far East, the Extreme North, and the Arctic shelf. No matter the region, Gazprom seeks to minimize its environmental impacts. To that end, the Company implements various environmental measures.
In 2015, Gazprom once again was recognized as the best Russian energy company among the world’s publicly traded companies by Carbon Disclosure Project (CDP), an international non-profit organization focused on greenhouse gas emissions and corporate climate strategies.
Gazprom topped the Environmental Impact category of the Environmental responsibility rating of oil and gas companies in Russia compiled by the World Wildlife Fund (WWF) and Creon.
Figures and facts
Gazprom’s air emissions went down from 3 million tons in 2013 to 2.8 million tons in 2015.
The Company’s wastewater discharges into surface water bodies fell from 4.4 billion cubic meters in 2013 to 3.85 billion cubic meters in 2015.
The area of reclaimed land grew from 14,000 hectares in 2013 to 18,200 hectares in 2015.
Waste generation is kept at the same level, with 4.7 million tons in 2013 and 4.95 million tons in 2015.
Air protection is the most significant and multifaceted of Gazprom Group’s environmental activities.
The Group’s corporate policy for climate protection takes into account Russia’s Energy Strategy until 2030 and the Environmental Doctrine of the Russian Federation. Gazprom is represented in the International Gas Union’s Programme Committee for Sustainable Development and is an active member of the IGU research group on greenhouse gas emissions.
Industrial environmental monitoring of emissions and discharges
Since 1992, Gazprom has worked to reduce emissions of the main greenhouse gases (carbon dioxide and methane). The Company develops its corporate system of greenhouse gas and pollutant monitoring, accounting and inventorying, as well as retrofits and modernizes its production facilities. In addition, Gazprom is stepping up the utilization of its associated petroleum gas (APG). Just ten years ago, more than half of its APG was flared.
Between 2011 and 2016, Gazprom’s air emissions were reduced by 294,000 tons.
The Company is actively expanding the gas grid coverage in Russian regions by promoting a wider use of natural gas, the most eco-friendly fuel of today.
The use of natural gas as a vehicle fuel is spreading. From an environmental perspective, gas is five times more efficient than gasoline and diesel fuel. The expansion of the NGV market is a top priority for Gazprom Group in Russia. The Group takes numerous efforts to convert vehicles to natural gas in Russian regions and Europe, gradually increasing its gas filling network and the share of NGVs in its vehicle fleet.
Land protection is one of Gazprom’s environmental priorities, as land is exposed to the largest impacts during hydrocarbon production, transportation and treatment.
Mobile laboratory at compressor station
Gazprom strives to minimize the area affected by its operations. The Company has a set of measures for that purpose: modular construction of production facilities, well clustering, laying of multi-string pipeline systems within a single routing, and introduction of horizontal and directional drilling. Adoption of advanced drilling techniques, which are spreading across Gazprom Group with every passing year, helps reduce industrial waste and waste disposal area, as well as prevent soil disturbance and pollution during production activities.
The Company preserves the integrity of permafrost areas by limiting site development, construction and assemblage operations to winter periods without disturbing the upper soil, which defrosts in summer. Other methods are used as well. For instance, natural gas pumped via the Bovanenkovo – Ukhta gas pipeline is cooled down to minus 2–10 degrees Celsius. The pipes are thermally insulated and produced by domestic manufacturers.
Cleanup and reclamation
Gazprom Group adopts innovative soil treatment methods and biotechnologies to remove hydrocarbon pollutants from soils and restore disturbed land. The technologies take climatic conditions into account and help reduce costs and accelerate soil reclamation.
In Yamal, for instance, Gazprom and Gazprom Neft introduced efficient soil treatment methods based on innovative biodegradation products containing microorganisms (hydrocarbon-degrading bacteria that can be used for biological treatment at low temperatures).
A plant-based treatment procedure for oil-polluted soils (phytoremediation) is also widely used at Gazprom Group. Grasses with branched root systems offer an optimal environment for hydrocarbons to decay due to better gas exchange in soil and a larger amount of biologically active substances produced by plant roots. Depending on the natural and climate conditions, balanced grass mixtures are used, providing a reliable biological indicator of soil reclamation.

The Group often undertakes reclamation measures in lands damaged decades earlier. For example, Gazprom Geologorazvedka initiated a reclamation campaign at the Tambey trading station in the Yamal Peninsula. Many hectares of the coastal line were cleared of production waste left in Ob Bay since the Soviet times. Scrap metal and debris were collected for further utilization.
In 2015, the total area of reclaimed soils reached 18,200 hectares, surpassing the record set in 2013 by 4,200 hectares.
The key to reducing the impact of production facilities on water resources is lowering water withdrawal and improving water treatment procedures.
In 2015, Gazprom Group put onstream 71 wastewater treatment facilities with a total daily capacity of 293,900 cubic meters, as well as 15 water recycling systems with a total daily capacity of around 8.8 million cubic meters.

Many of Gazprom’s subsidiaries and organizations play an important social role by supplying water to and accepting sewage waters from population centers to water treatment facilities.
Gazprom has developed and adopted a Biodiversity Preservation Program. The Company takes a large number of special environmental measures for fish stock protection and reproduction, as well as land cleanup and improvement (including coastal areas), and provides financial support to specialized organizations.

In the last few years, Gazprom Group released several millions of fingerlings into the sea. Offshore facilities, such as the Prirazlomnaya platform, use fish protection devices during construction and operation.
Industrial and residential waste disposal is associated with high environmental risks. Therefore, Gazprom Group strives to adopt state-of-the-art practices and technologies for waste minimization. The Group is constantly reducing its accumulated waste.

Gazprom pays great attention to eco-friendly handling of oil sludge. Oil sludge is oil-containing waste consisting of oil products, water, sand or clay. Oil sludge is produced as a result of refining and pipeline cleaning. Most of oil-containing waste is a Class III hazard, i.e. moderately hazardous and likely to disturb the ecosystem (it will take 10 years for the ecosystem to recover after the adverse impact is mitigated).
