Australian Climate Change Authority which is under threat of being abolished by the Government says a 5% target is not a credible option for Australia.
15-25% reductions are needed to ease the climate burden beyond 2020. For the Coalition’s $3.2bn Direct Action plan which is designed to barely meet the 5% minimum target, suggestions for increased reductions is probably unwelcome.
