In 2012, 2015, and again in 2018, DOE has released studies to assess the macroeconomic impacts of liquefied natural gas (LNG) exports, to inform the decisions on applications seeking authorization to export LNG from the lower-48 states to non-free trade agreement countries. 

The 2012 LNG Export Study evaluated exports in the range of 0 to 12 billion cubic feet (Bcf) per day. 

The 2015 LNG Export Study evaluated exports in the range of 12 to 20 billion cubic feet (Bcf) per day.

The 2018 LNG Export Study evaluated a wide range of export scenarios, including examining the probability of various export scenarios.
