Federal Labor will take the hand of business when it comes to climate change, rejecting an offer to work with the Greens.

Greens leader Richard Di Natale will on Wednesday offer to partner with Labor if it wins the election, saying it’s the only chance of getting proper climate action.

But Labor leader Bill Shorten has ruled out a coalition with the minor party.

“Sorry Richard, it’s not happening,” he told reporters in the Adelaide seat of Boothby, which the Liberals hold by 2.7 per cent.

If Labor wins government Mr Shorten doesn’t expect the Senate to stand in the way of his party’s policies.

The Labor leader was grilled on his party’s climate policies, with the party’s energy spokesman Mark Butler on hand to explain the finer details.

Mr Butler says Labor has had “deep engagement with the business community”.

Business has told Labor they want the safeguard mechanism to continue, which was introduced by the Liberal government.

It puts a limit on how much carbon the nation’s top 250 polluters can emit, giving them the option of buying international offsets if they fail to meet the target.

The Labor leader has taken his election campaign to Adelaide, where he promised to unlock the renewable energy potential of the Spencer Gulf if he wins the election.

Mr Shorten has pledged to make the area a renewable energy zone, which will see it benefit from a $5 billion Labor fund.

It’s the third day in a row the Labor leader has visited either a childcare centre or primary school, avoiding possible grillings from punters.

Mr Shorten has rejected concerns that voters are worried about the unknown cost of his climate plan.

“The Australian people have already worked out what the Liberal Party haven’t – climate change is real,” he said.

Mr Shorten has said it’s impossible to put a price on his 45 per cent emissions reduction plan as businesses will choose how to reduce their pollution.

The opposition leader said he had never met Labor’s disendorsed NT Senate candidate Wayne Kurnoth, who was dumped over questionable social media posts including peddling conspiracy theories about the Rothschild banking family controlling the world.

However, Mr Shorten has been pictured with Mr Kurnoth on his now-deleted Facebook page.

Mr Shorten has also been on the attack against the coalition’s preference deal with Clive Palmer, but Labor has put his party above the Liberals on their how-to-vote cards in 87 lower house seats, including putting it second in two Tasmanian seats.
