Importing gas to replace domestic supply could push emissions up 20%, AGL says

Energy company says importing LNG will firm up renewable energy projects but critics say gas is already more expensive than clean alternatives

Controversial plans to import liquefied natural gas into Australia to fill a shortfall as domestic gas is exported to Asia would significantly increase greenhouse gas emissions, AGL has conceded.

Energy companies have proposed four LNG import terminals for the east coast to ensure gas supply and ease high prices. The imported natural gas would effectively replace the two-thirds of gas sold overseas from export plants in Queensland.
