Australia will not be signing a communique at the Paris climate summit about phasing out fossil fuel subsidies.

Nationals MPs and senators were concerned the pledge could affect the multi-billion-dollar diesel fuel rebate for farmers and miners.

The communique is due to be presented on Monday, but a Federal Government source has told the ABC Australia will not be signing it.

"Hooray," Nationals deputy leader Barnaby Joyce said when told the news on Radio National.

"It just goes to show what a successful political unit the National Party is and I want all your listeners to know that.

"It's a win for common sense and the National Party."

Industries such as agriculture, fishing and forestry can access a rebate on the diesel excise paid.

The fossil-fuel subsidy reform communique encourages countries to phase out subsidies to help limit global warming to 2 degrees Celsius.

The Nationals argued the fuel rebate was not a subsidy.

"There's a tax that goes on your road usage, now if you're not on a public road why should you pay a tax on road usage?" Senator Joyce asked.

"When you plant a crop you don't plant it in the middle of the M1, when you're out working with cattle you're not out on the Cahill Expressway.

"The same thing goes with mining vehicles they're in a mine they're not on a public road."

Earlier on Monday, Queensland Liberal-National MP George Christensen urged the Government not to sign the communique.

"To sign this is madness. It will cost jobs & give greens ammo to attack coal further," Mr Christensen said on Twitter.

The Government initially sought to downplay concerns the statement would affect the rebate.

Acting Prime Minister Warren Truss said nothing out of the Paris talks would have "any impact" on the scheme.

But after considering the matter, the Government has decided not to sign the document at all.
