According to a report released on December 8, 2020 by the Natural Resources Defense Council (NRDC), a non-profit environmental advocacy group, projected increases in U.S. exports of liquefied natural gas (LNG) are likely incompatible with holding the rise in global temperature at 1.5° Celsius.[1] [2] The report, titled “Sailing to Nowhere: Liquefied Natural Gas Is Not an Effective Climate Strategy”, found that although greenhouse gas (GHG) emissions from U.S. LNG are lower than coal over a 100-year time span, methane’s more immediate impact compared to CO2 means the "near-term" climate effect of LNG over the next 20 years is similar to coal. The emissions from the LNG industry will generate up to 213 million metric tons of new GHG emissions by 2030, which is equal to the annual emissions of 28 to 45 million fossil fuel-powered cars, according to the report. Much of LNG’s climate impact also comes from the extraction, transport, liquefaction, and re-gasification of LNG. The report also emphasized that the long lifespan of LNG infrastructure “locks in” fossil fuels instead clean energy which prevents of clean energy technologies like wind and solar, which produce significantly lower life-cycle GHG emissions, from expanding. The report concluded that the estimated social cost of U.S. LNG exports was $8.1 billion in 2019 and would be $30.5 billion per year by 2030.
