This dataset describes the construction of a 1m natural gas pipeline. The long-distance pipelines for natural gas play a crucial role in transporting natural gas from production sites or import locations to the consumer market. The inventory data is formed by consolidating data from various sources, and some data has been corrected and updated according to the average values reported in the industry reports. The dataset includes building materials, energy consumption, laying projects, and pipeline decommissioning, but does not include energy consumption, raw materials, and operational emissions used in the decommissioning process, nor does it include the manufacturing of production equipment, plant construction, and other infrastructure beyond the dataset boundary.
