Fugitive Methane Emissions: The Climate Implications of U.S. Shale Gas Exports
In addition to habitat disruption and impacts on local air and water quality, one of the most significant implications of natural gas production is fugitive methane emissions …
… methane is a potent greenhouse gas—at least 25 times stronger than carbon dioxide. In fact, this fugitive methane amounts to more greenhouse gas emissions than all of the direct and indirect emissions from U.S. iron and steel, cement and aluminum manufacturing combined.
Domestically, LNG exports would likely raise natural gas prices, resulting in the greater use of coal for U.S. electric power generation.
In order to send natural gas overseas, you must liquefy it, transport it and then re-gasify it. This is an extremely energy- and emissions-intensive process.
