<p>In January 2024, U.S. President Joe Biden issued a moratorium on the expansion of liquefied natural gas (LNG) exports, citing the need for a comprehensive assessment of the environmental, economic, and geopolitical impacts. A recent study by Professor Robert Howarth, which was cited among other sources to justify President Biden&#39;s moratorium, compared life cycle greenhouse gas (GHG) emissions of LNG exported from the United States to coal. According to Howarth&#39;s findings, LNG has a larger GHG footprint than coal and his study recommended that additional resources should not be allocated to further LNG projects. Is LNG a cleaner energy source than coal? What is the basis for Professor Robert Howarth&rsquo;s assertions that coal has less of a GHG footprint than LNG? Are there feasible technological innovations that can make LNG and coal less polluting?&nbsp;</p>
