Recent technological developments have led to an increase in the domestic supply of natural gas. As a result, there is interest among some parties in exporting liquefied natural gas (LNG) to take advantage of international markets. This has placed new attention on the laws and regulations governing the export of natural gas as well as other fossil fuels. In most cases, export of fossil fuels requires federal authorisation of both the act of exporting the fuel and the facility that will be employed to export the fuel. This book discusses federal permitting and oversight of export of fossil fuels; new opportunities and uncertain outcomes of United States natural gas exports; United States coal exports; and coal as a key player in expanded United States energy exports.
