“Tony Abbott will only be satisfied when a verse about coal-fired power stations is inserted into our national anthem,” said Mr Bandt.
“Abbott and the Nationals are working together to try and water down the already inadequate NEG and sabotage effective action to combat dangerous global warming.
“Josh Frydenberg needs to come clean, before COAG, on any promises he’s made and deals he’s doing with the coal-huggers to get support for the NEG.
“Since this government came to power, we’ve gone from world leading climate change legislation to rising pollution and a touted $5 billion coal fund.
“Any push to subsidise coal will affect how the NEG works. Full transparency is essential so that states and territories know exactly what they’re being asked to sign up to.
“I’m worried that after COAG, they’ll announce some pro-pollution measures that will make a bad policy even worse.
“It’s essential that energy ministers see the full package before they decide whether or not to approve the NEG.”
