1 Scope
This document:
provides the general part of the method to calculate the greenhouse gas (GHG) emissions
throughout the liquefied natural gas (LNG) chain, a means to determine their carbon
footprint;
defines preferred units of measurement and necessary conversions;
recommends instrumentation and estimation methods to monitor and report GHG emissions.
Some emissions are measured; and some are estimated.
This document covers all facilities in the LNG chain. 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 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.
This document describes the allocation of GHG emissions to LNG and other hydrocarbon
products where other ...
