According to the International Energy Agency, US energy-related emissions of carbon dioxide, the main greenhouse gas, have fallen 450m tonnes over the past five years – the largest drop among all countries surveyed.

Fatih Birol, IEA chief economist, attributed the fall to improvements in fuel efficiency in the transport sector and a “major shift” from coal to gas in the power sector. “This is a success story based on a combination of policy and technology – policy driving greater efficiency and technology making shale gas production viable,” Mr Birol told the Financial Times.

Shale gas has transformed the US energy landscape, with surging production pushing gas prices down to 10-year lows and heralding an industrial renaissance. But it is also the subject of a heated environmental debate, with critics alleging that the production process can pollute groundwater.

...

The agency has calculated that in order to contain rising temperatures and avoid the most damaging effects of global warming, annual energy-related emissions should be no more than 32.6GT by 2017. “We are now only 1GT away from that, with five years still to go,” Mr Birol warned. “The door to a 2 degree trajectory is about to close, and to close forever.”
