A new assessment of the Coalition government’s climate change policies says Australia will fall well short of its “inadequate” Paris climate targets, and will likely increase emissions by nearly as much as it has promised to cut them.

The assessment from Climate Action Tracker says that Australia’s target falls well short of the effort needed to limit warming to below 2°C, let alone the stronger aspirational target of 1.5°C that was included in the Paris Agreement.

Malcolm Turnbull delivers a speech at Heads of States’ Statements ceremony of the COP21 World Climate Change Conference 2015 in Paris.

“If most other countries followed the Australia approach, global warming would exceed  3°C to 4°C,” the report says.

The Climate Action Tracker report is not the first to highlight Australia’s pathetically inadequate climate policies, nor will it be the last. A slew of reports is expected in coming days and weeks as the Paris Agreement comes into force from Friday and new climate talks begin in Marrakesh in Morocco on Monday.

Australia is likely to be questioned intensely by many countries, including its major trading partners, over its climate policies, particularly the effectiveness of its Direct Action policy, which prime minister Malcolm Turnbull has embraced despite ridiculing it before replacing Tony Abbott as leader just over a year ago.

Fairfax Media reported last month that China, the US and other countries have put more than 30 questions to the Turnbull government, asking for detail about how Australia will meet its 2030 emissions target and raising concerns about a lack of transparency over how the government calculates and reports emissions.

The Australian government has admitted it has not even modelled the impact of its own policies and whether they would reach their target, and it is unclear whether a promised 2017 review will lead to new policies or simply be a “situation report” on the current trajectory.

Others have done the modelling, though, which shows it comes up short. The Climate Change Authority has said previously – before its board was stacked with Coalition government appointees – that the Coalition’s target was well below what could be considered Australia’s “fair share”.

It says that Australia’s target should be 40 to 60 per cent below 2000 levels by 2030 (or around 45-65 per cent on 2005 levels, compared to the current target of 26-28 per cent).

The Climate Institute has said that with current targets, Australia’s per capita emissions in 2030 would be around three times higher than global per capita emissions benchmarks that are consistent with Paris Agreement objectives.

Australia, though, is not the only country to be dragging its heels. A new report to be released late Thursday will confirm that the world needs to lift its efforts because current policies are falling 25 per cent below what is required to meet the Paris target.

The Less Developed Country block on Wednesday said that the current Paris pledges have the world on course for 3-3.5°C of warming above pre-industrial levels. It wants stronger action, particularly from developed nations.

The problem with Australia is that it is unclear whether it can meet its own inadequate INDC (Intended Nationally Determined Contribution), the pledge lodged in Paris last year.

“To meet its 2030 emissions targets, Australian emissions should decrease by an average rate of 1.9 per cent per year until 2030; instead, with current policies, they are set to increase by an average rate of 1.2 per cent per year,” the Climate Action Tracker report says.

It also adds to questions around the Emissions Reduction Fund, which it says will not set the country on a path to meet its targets and may only be funding emission reduction projects that would have occurred anyway.
