PGN's environmental management activities focus on a number of areas:
PGN rehabilitates areas excavated for the construction of transmission and distribution pipelines. Because there are no extractive processes involved, the excavated earth is used directly to cover the pipeline, which is buried below ground. Any remaining soil is used to level out the gas pipeline route. Leveling is done to ensure that safety inspections of the pipeline can be carried out properly.
PGN plants the areas along the length of the pipeline with trees and shrubs that have secondary side roots. PGN makes regular inspections and tends to the condition of the greenery along the pipeline route.
For the installation of marine pipelines, PGN follows the procedures stipulated in the AMDAL. According to the AMDAL, there are no permanent significant impacts arising from the installation of undersea transmission pipelines.
In addition to the areas along pipeline routes for which it is responsible, PGN carries out environmental improvement programs in the form of tree planting, both in PGN's operational areas and other areas. A total of 55,470 trees have been planted so far.
Other Environmental Programs
PGN also supports re-greening programs in other areas as part of its commitment to environmental conservation. These activities include:
- Assistance for the planting of more than 1,316,648 trees around PGN's area of operation.
- Working with an environmental rescue group (Green Radio) to plant trees in various areas.
Although our operations do not have a direct adverse impact on the environment, PGN participates in environmental conservation by making a series of efficiency measures with regard to use of natural resources, particularly energy sources, and to maintaining a clean atmosphere.
PGN's operational activities make no direct use of raw materials or water, only energy. Energy is used to operate the compressor turbines to enable the gas in the transmission network to "flow" towards the users' installations, such as power plants, the ceramics and glass industries, household consumers and so on. The energy source used for this purpose is natural gas, which is more environmentally friendly than fossil fuels.
