The study analyzes greenhouse gas (GHG) emissions across the liquefied natural gas (LNG) value chain, focusing on liquefaction, shipping, and regasification processes using detailed process-level data. For US LNG exports, average gate-to-gate emissions were estimated at 0.220 and 0.269 tonnes CO₂e per tonne of gas liquefied for Sabine Pass and Cove Point terminals, respectively. Shipping emissions, based on 331 voyages to 30 countries, were highest for deliveries to Asia, averaging 0.200 tonnes CO₂e per tonne of gas delivered due to longer transport distances. Regasification emissions were found to be 0.021 tonnes CO₂e per tonne of gas regasified. The models developed offer granular emissions estimates and can be adapted for global analysis, providing valuable insights for decarbonization and sustainability efforts in the LNG sector.
