A new liquefied natural gas plant proposed for Tacoma, Washington will result in a net reduction of greenhouse gases for the Washington State, but only if the natural gas that supplied it comes from B.C. (British Columbia). This is the recommendation of the Puget Sound Clean Air Agency in a supplemental environmental assessment for the facility.
The LNG plant would not be exporting LNG, rather the LNG it would produce would be used as an alternative fuel for marine vessels and trucks, as well as providing a backup supply of natural gas.
Because the LNG that the Tacoma plant would produce would replace other fuels, like diesel, there would be a net benefit in terms of lower GHGs. Read more here;
