A report of the G20's transition to low carbon economies has rated Australia as a low performer when it comes to climate policy, with the federal government being criticised for their lack of ambition when it comes to their strategy and their continued support of coal.

Other countries that were singled out in the Brown to Green report for performing at a low level were the US, Russia, Japan, Saudi Arabia and Turkey.

China, Brazil, France, Germany, India, Mexico and South Africa were among the countries that were ranked high in terms of their actions on climate change. 

The report claims that based on current renewable policies, Australia will not hit its carbon dioxide reduction targets - 26-28% from 2005 levels by 2030 - that were established as part of the Paris agreements.

"Australia has made some progress in supporting the deployment of renewable energy schemes and enhancing energy efficiency, particularly in the residential sector," the report said.

"However, experts claim this is insufficient given Australia's high emissions and its large potential for the deployment of renewables."

According to the report, of particularly concern is the reversing trend of falling carbon emissions from coal-fired power stations after the carbon tax was repealed in 2014.

"As a consequence, emissions from electricity production that has been covered by the scheme are rising again, while the federal government continues to create political uncertainty on the future of renewable energy," the report said.

It does however note that after a year of record investment and with coal on the decline, Australia is gearing up to maintain its renewables target, and also ensure grid stability through increased storage.

But with 35% of its energy supplied by coal in 2014, Australia still has one of the highest coal shares in the G20.
According to the report, G20 countries account for 75% of global greenhouse gas emissions. 

Though it was also revealed in the report that G20 countries account for 98% of the global installed capacity of wind power, 97% of solar power, and 93% of electric vehicles.

Apart from Russia, all other countries in the G20 have seen growth in renewables with China, the Republic of Korea, Turkey, and the UK all experiencing the strongest growth.
