If the Coalition give into a net-zero 2050 target without knowing exactly how to pay for it, it will simply highlight how the “left keeps winning the culture war” even though it keeps losing elections, according to Peta Credlin.

Prime Minister Scott Morrison indicated his ambition to reach net-zero emissions, but warned the time has “not yet arrived” to make the target.

He said his government won’t set out a 2050 net-zero emissions target until it could be confident it knows how it will be costed.

The prime minister pointed out if the goal of getting the economy to net zero was not achieved by technology, the only other solution would be tax.

“Tax. That’s the only other way to get there,” he said.

“My commitment to Australians that I will not tax our way to net zero by 2050 is a very, very important one”.

Ms Credlin said she hopes the prime minister does not get “sucked into another one of the left’s games” in conceding he’d like to reach net zero.

“What a Coalition government does, in terms of climate change, is never ever enough for the green-left, even when the commitments are met,” she said.

“The socialists want everything upped, more subsidies to pay for their green activism, more jobs sent offshore, and presumably everyone forced into a greater dependency on the state”.

Ms Credlin said given 2021 could be an election year, there is no doubt some Liberals have canvassed the prime minister to simply make the commitment without any costings.

“To do that, to set a target you have no idea what it will cost to meet, would be a big mistake,” she said.

“Once any hard and fast target is enshrined, the bureaucracy take it as holy writ, and even Coalition governments end up running on Labor’s agenda.”
