| Resumen: | This document provides the general part of the method to calculate the GHG emissions throughout the LNG chain. The specific requirements on natural gas production and transport to LNG plant, liquefaction, shipping and regasification are addressed in separate parts. The document covers all facilities in the LNG chain. This document covers all GHG emissions. 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. The facilities are considered "under operation", including emissions associated with initial start-up, maintenance, turnaround and restarts after maintenance or upset. The construction, commissioning, extension and decommissioning phases are excluded from this document but can be assessed separately. This document describes the allocation of GHG emissions to LNG and other hydrocarbon products where other products are produced (e. g. LPG, domestic gas, condensates, sulphur, etc.). This document defines preferred units of measurement and necessary conversions. This document also recommends instrumentation and estimations methods to monitor and report GHG emissions. Some emissions are measured, and some are estimated. This document is applicable to the LNG industry. Applications include the provision of method to calculate GHG emissions through a standardized and auditable method, a means to determine their carbon footprint. 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. A list of all parts in the ISO 6338 series can be found on the ISO website. |
