India is the world's third largest emitter of greenhouse gases and relies heavily on coal, gas and oil imports to meet its energy needs and fuel its economic expansion.

Its energy consumption is bound to grow as it targets 8 – 9% economic growth from around 7% in 2016-17.

To cut the country's carbon footprint, New Delhi wants to raise the use of gas in its energy mix to 15% in three to four years from 6.5% now.

LNG imports, which account for 44% of gas use in the country, are duty free only if shipped in for the power sector.
