"Our projected emissions in 2030 will increase[over the next decade] and be only 7 per cent below 2005 levels,"he said.

Mr Wood said emissions per capita were improving,as the government claims,and this was important,but he said this was not the key pledge in the Paris agreement on climate change.
"The only genuinely relevant measure is total emissions,"he said.
The national commitment under Paris centres on the cumulative tonnes of carbon reduced over the decade from 2021 to 2030,meant to be 26 to 28 per cent below 2005 levels. The latest figure for this is 695 million tonnes.
The government may achieve the cumulative target with the help of 367 million tonnes of"carryover"credits from the Kyoto agreement,but Mr Wood noted this would not mean the emissions in 2030 were actually 26 per cent below the starting point of 605 million tonnes.
The talking points relied heavily on the $3.5 billion Climate Solutions Fund to claim that government policies would deliver another 328 million tonnes of abatement by 2030 and therefore achieve the target,but Mr Wood rejected this.
"That isnot what the official figures show,"Mr Wood said.

A Department of the Environment chart shows the Climate Solutions Fund delivers about 100 million tonnes in emission reductions but the remainder is expected to come from other measures or natural trends.
Other reductions come from energy efficiency,the adoption of electric vehicles and the"battery of the nation"hydro power strategy.
"The best part of 100 million tonnes[of abatement] is assumed to come from technology improvements,both a debatable assumption and definitely not part of the Climate Solutions Fund,"Mr Wood said.
"And around 30 to 40 million tonnes comes from energy performance improvements,also not connected with the Climate Solutions Fund."
Australian Conservation Foundation climate change campaigner Suzanne Harter said the upward trend in emissions showed the Coalition had not made progress on the problem.
"Following the repeal the national carbon price in June 2014 there has been a growth in greenhouse pollution,"Ms Harter said.
"Since the March quarter of 2014,just before the carbon price was repealed,emissions have increased 1.2 per cent."
"The cumulative increase is much more significant and jeopardises Australia's ability to meet our international commitments."
