Commonwealth LNG in a letter said it has been waiting 14 months for non-free trade approval, and has had no sign of a decision.

U.S. Department of Energy (DOE) reviews for LNG export permits have lengthened under Biden to 11 months or more, from seven weeks under former President Donald Trump, a Republican who worked to maximize U.S. energy output.
Officials from the DOE and White House have been meeting to determine whether federal regulators should factor in climate change when deciding whether a proposed gas export project meets the national interest, Politico reported on Tuesday, citing sources familiar with the discussions.
