Mr Sims said a business that makes “a good faith” approach to calculating the carbon price for their business “has nothing to fear from the ACCC”.

“However businesses seeking to mislead consumers by making false price claims about the carbon price can expect a call from the ACCC,” he said.

“The ACCC hotline will make it easier for consumers and small business to alert the ACCC if what they’re seeing doesn’t look quite right. Consumers or businesses can contact us if they think a carbon price claim is false.”
