It may surprise many that Michael Fraser, CEO of Australia's largest carbon emitter listed on the Australian Stock Exchange, sits at number three on the list of the most powerful people behind Australia's push to a low-carbon economy.

But there isn't any other major energy company in Australia that has taken an active and unambiguous stand in favour of pricing carbon and maintaining Australia's Renewable Energy Target the way Fraser's AGL has. The other major private sector energy companies have either outright lobbied against the carbon price and the RET (EnergyAustralia and GDF Suez; formerly International Power), or in the case of Santos and Origin Energy backed away from prominent support for the carbon price as their LNG businesses became central to growth, while never being particularly supportive of the enlarged RET.
