A Cheniere Energy Inc. study of greenhouse gas (GHG) emissions along the company’s LNG supply chain showed a more than 20% drop in GHG emissions than what was found in an earlier government study, the company announced Nov. 12.

Correct estimates of LNG suppliers’ GHG emissions have been important to the overall industry in 2023 and 2024, as the issue frequently comes up in the environmental lawsuits developing LNG facilities face.

According to Houston-based Cheniere, it’s peer-reviewed study used an algorithm modeling natural gas pathways on the supply chain in 2022. The chain includes the basin where the gas was produced, the transmission network and Cheniere’s LNG liquefication facilities on Sabine Pass in Southeast Texas and Corpus Christi, Texas.

Cheniere’s study showed that, in all cases along the supply chain, the 2022 GHG emission intensity level was more than 20% lower than a U.S. Department of Energy National Energy Technology Laboratory study done in 2019.

“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.
