President Obama defines the natural gas as a fuel to play central roles in the transition to a clean energy future and measures have been taken to support the development natural gas：carbon pollution standards for the existing fossil-fueled power plants were proposed for the first time. The greenhouse gas emission standards were also released to boost construction of natural gas fired power plants and to discourage building of coal-fired plant. Many tax incentives and fiscal policies were introduced to push more natural gas vehicles being produced and used in the transportation sector. The first-ever federal standards addressing methane emissions in the newly released oil and gas regulations constitutes the most important policy in the Obama Administration to prevent methane emission. The Administration continues to advance the exports of the U.S. liquefied natural gas（LNG）and also strengthened the environment assessment in the approval procedures. Exports of the U.S. LNG are in sight.
