The gas industry's future remains bright. Three major shifts will shape the evolution of global natural gas markets in the next five years - growing imports from China, greater industrial demand, and rising production from the United States. The structural shift will determine the evolution of the market at a time when growth in emerging markets is sustained by strong economic expansion and strong policy support to curb air pollution. Industry becomes a major player in gas markets, while the United States cements its position as a top producer and exporter thanks to its shale revolution. Gas 2018, the latest IEA annual market report, assesses these trends and provides a detailed analysis of supply and trade developments, infrastructure investments, and demand-growth forecast through 2023. The report analyses the main changes that will likely transform the natural gas market, including market reforms that shape supply and demand patterns in key Asian economies and developments in the LNG market - the main driver of interregional natural gas trade growth.
