AUSTRALIA'S efforts on climate change have been recognised as among the four nations worldwide least likely to achieve their international promises.

The report comes days after the US and China signed a joint deal to reduce their carbon emissions, and rejects previous claims the government's Direct Action plan or other efforts will reach the 5% reduction by the 2020 target.
