Cheniere Study Shows Lower GHG Emissions in Updated LNG Life Cycle Analysis
(P&GJ) — Cheniere Energy recently published an updated life cycle assessment (LCA) of greenhouse gas (GHG) emissions tied to its liquefied natural gas (LNG) operations, incorporating new data from its supply chain.
The peer-reviewed study, which appears in the American Chemical Society’s Sustainable Chemistry & Engineering Journal, introduces an advanced gas-pathing algorithm designed to improve emissions modeling across the company's production and distribution networks.
The report benefits from Cheniere’s multi-year Quantification, Monitoring, Reporting, and Verification (QMRV) program, pulling data from its facilities and working closely with industry partners, including gas producers and midstream providers. This updated analysis covers 2022 data on natural gas flows from production basins to Cheniere’s liquefaction facilities in Sabine Pass and Corpus Christi.
According to Cheniere, the study demonstrates that its 2022 LNG emissions intensity is 20-28% lower than estimates from a 2019 U.S. Department of Energy study by the National Energy Technology Laboratory (NETL). The findings emphasize the importance of direct emissions measurements for accurate assessment of GHG emissions across the LNG supply chain.
“This study reinforces the environmental competitiveness of Cheniere’s LNG, while demonstrating the value of direct emissions measurement to better understand the environmental footprint of LNG and identify areas for improvement,” said Jack Fusco, Cheniere’s President and CEO. “We are charting a path forward with concrete data, science, and actions to ensure LNG and natural gas continue to play a role in the global transition to a lower-carbon future for decades to come.”
The study is co-authored by experts from the University of Texas at Austin, Queen Mary University of London, Colorado School of Mines, Rystad Energy, KeyLogic Systems, and Cheniere.
