Developers of a long-planned US liquefied natural gas export terminal in Louisiana have relaunched the project with an ambitious goal to be the first net-zero carbon emissions LNG facility in the world.

They will restart the process of getting a permit from the Federal Energy Regulatory Commission early next year, after exiting the federal permitting process in 2017 as competition had stacked up in the US LNG sector, the project's chairman Charles Roemer IV said last week.
