Without any mechanism to discourage additional carbon emissions, the Coalition’s "direct action" climate plan may perversely reward them.

The Coalition plan proposes cash rewards for actions to "support 140 million tonnes of abatement per annum by 2020 to meet our 5% target", at a cost to taxpayers said to be $3.2 billion over the first four years. (The government now assesses that abatement task at 160 metric tonnes, for the meagre 5% goal of both major parties -- which stands in sharp contrast to the carbon budget approach advocated in the recent Climate Commission report.)
