Abstract

This document provides a method to calculate the GHG emissions during natural gas production (onshore or offshore), gas processing and gas transport to LNG liquefaction plant. The document covers all facilities associated with producing natural gas, including: — Drilling (exploration, appraisal, and development) & Production wells, — Gas gathering network and boosting stations (if any), — Gas processing facilities (if any), transport gas pipelines with compression stations (if any). This document covers all GHG emissions associated with production, process and transport of natural gas to the LNG liquefaction plant. These emissions spread across scope 1, scope 2 and scope 3 of the responsible organization. Scope 1, 2 and 3 are defined in this document. All emissions sources are covered including flaring, combustion, cold vents, process vents, fugitive leaks and emissions associated with imported energy. Gases to be considered include CO2, CH4, N2O and fluorinated gases. This document was prepared by Technical Committee ISO/TC 67, Oil and gas industries including lower carbon energy, Subcommittee SC 9, Production, transport and storage facilities for cryogenic liquefied gases.
