In June 2014, under authority from the Clean Air Act (CAA) section 111 (d), the Environmental Protection Agency (EPA) published their draft Clean Power Plan, a proposed rule to limit carbon emissions from existing large
coal facilities across the country.
Weiss said that, while natural gas burns cleaner, the NETL study concluded that the end - to - end emissions involved in moving U.S. natural gas to an LNG export
facility, then liquefying it, then shipping it
across the ocean, then de-liquefying it, and shipping it to users in other
countries, would be as energy and emissions intensive, or more, than using regionally produced
coal — i.e., because of the LNG export supply chain, it has no advantage over
coal.
Across the
country, these providers are mostly electricity generation sources like natural gas or
coal plants, solar farms, and hydroelectricity
facilities.
