Abstract As we enter into 21 st century, the availability of traditional energy sources like fossil fuels is elongated to the maximum supply factor and inter-associated subjects of ever escalating demand and limited supply have resulted in exerting pressure for increased voice over “ energy security “ as both consumers and producers fight back to control costs , geopolitics , environment and prices. These issues associated with advancement in technology have pushed an historic escalation in LNG projects globally with Qatar turning to be the market head in LNG liquefaction capabilities. This research study will offer an insight into the growing and evolving part that LNG will play in catering the globe’s energy demands in the near future. In the literature review section of this research study, the historical background of usage of LNG predominantly as a regional fuel in the regions of Asia-pacific, the European region and North American / Atlantic Basin will be provided. Further, it will also discuss about the increasing demand for LNG globally and how the increase in demand for LNG will affect LNG markets globally will be discussed in detail. A detailed debate will be made about the ever growing globalization of the LNG markets worldwide and whether LNG could be traded as international merchandise in the future. Further, there will be some symposium about the both long-term and short-term LNG contracts and will also address about the safety and environmental concerns relating to LNG and will deliberate about how the environmental antagonism to LNG might influence the long run development of the global market for LNG with particular attention to USA where many ongoing LNG import terminals have been obstructed by environmental activists. Finally, this research study will conclude with findings that how LNG is progressing into an international, market-driven product that is connecting the international gas markets. (Sakmar 2009:1). Introduction In 21 st century, energy has become one of the vital international political issues. The globe is witnessing multiple energy confronts, soaring energy prices, climate change, global resource competition and energy poverty. Further, the emergence of new vibrant economies like Brazil, Russia, India and China (BRICs) have hastened and worsened the present energy trends. India and China are emerging as new demand centres in the global energy system, whereas Brazil and Russia have become as significant energy exporters. The global economy is still reliant on varied energy resources namely natural gas, coal, oil, which is known as fossil fuels. This is quite distressing as these resources are depletable, notably costlier, geographically saturated and very polluting thereby resulting in global warming. The existing substitutes for fossil fuels like biomass energy, nuclear energy, and hydro-power are highly contentious due to their negative risks or side-effects. Further, global energy demand is set to increase many fold in the ensuing decades, especially in the developing and emerging world. It is estimated that global energy demand is likely to exceed by over fifty percent by 2030 and up to eighty percent of this increased demand will be catered by fossil fuels. (IEA 2007b). (Lesage, Graaf & Westphal 2010:2). Energy experts are of the view that in the 21 st century, traditional energy sources are shrinking slowly and intertwined issues of a steady increase in demand and constricted supply have compelled to new demand for “energy security” as both consum
