| Abstract [eng] |
The aim of this work is to assess the environmental impacts of natural gas transmission activities over the whole life cycle. Significant environmental impacts are likely to arise from gas transmission activities. There may be controlled and truly uncontrolled gas leaks due to leaks in the pipeline or repairs that may have an environmental impact. The gas transmission activities of the company have a target of 60% reduction of GHG emissions over a period of 5 years, and there is also a need to assess other environmental impact indicators to monitor the environmental footprint of the company and track the effectiveness of the mitigation measures taken.The life cycle assessment of the natural gas transmission activities shows that the main areas of concern: controlled release of methane gas (mainly due to repair works) - 47%; gas transportation (uncontrolled leakage) - 42%; pipeline infrastructure (land use) - 10%; other energy and fuel consumption - 5%. Six mitigation measures have been selected: use of a mobile gas compressor; conversion of internal combustion engine cars to electric cars; use of green energy; transport of gas-by-gas carriers to gas distribution stations; use of a flare; and pipeline repairs using cut-and-cover technology. |
