REDUCTION OF GREENHOUSE GAS EMISSIONS

GRI 305-7
 
The PGNiG Group places great importance on reducing gas and particulate matter emissions into the atmosphere. It has been steadily reducing the amount of pollutants generated by transportation, combustion processes in heat sources, fuel reloading and industrial processes (gas combustion at flares, gas venting, emissions from compressor stations and compressors). 

The methods of reducing emissions of pollutants into the air include using gas as a low-emission fuel, monitoring fuel consumption, reducing the energy intensity of industrial processes and modernising or replacing heat sources used for the Group’s own needs. PGNiG Group companies implemented environmental projects in 2019.

PGNiG seeks to reduce GHG air emissions from its hydrocarbon exploration operations.

PGNiG OD replaced two central heating boilers with a total capacity of 240 kW in a building in Lublin. The new boilers offer considerably higher energy efficiency, lower consumption of gas and reduced carbon dioxide emissions. In addition, a new heat pump system was installed, reducing the emissions of carbon oxides, nitrogen oxides and carbon dioxide.

The PGNiG Zielona Góra Branch upgraded its gas compressor station and modernised the boiler house, dismantling and decommissioning four water boilers and replacing them with a single state-of-the-art water boiler unit. The project helped reduce flue gas emissions. 

PGNiG TERMIKA Group companies employ various methods to air protection, including organisational solutions and systems for appropriate fuel management. Appropriate combustion techniques are also used, such as secondary combustion which involves flue gas treatment in air protection system.

NOx, SOx, and other significant air emissions (GRI 305-7)

Oil and gas exploration and production activities, gas distribution, and modernisation, maintenance and repair works undertalen by the PGNiG Group generate air pollutants such as gases (SO2, NOx, CO, CO2, CH4), particulate matter, aromatic hydrocarbons, aldehydes, heavy metals, metallic and non-metallic elements.
