ACCI fears uncertainty from Palmer's ETS

Business believes Clive Palmer's new-found stance on carbon pricing is likely to create uncertainty that will stifle investment and dampen jobs growth.

The Australian Chamber of Commerce and Industry, a long-time opponent of the carbon tax, has welcomed the Palmer United Party leader's decision to support repeal of the impost.

But ACCI CEO Kate Carnell is worried that Mr Palmer has flagged support for some form of global emissions trading scheme.

The party seemed to be taking Australia one step forward and one step back, she told reporters in Canberra on Thursday.

While welcoming the opening of a meaningful dialogue between Mr Palmer and Prime Minister Tony Abbott, Ms Carnell warned business would suffer from a new period of uncertainty.

"That uncertainty will no doubt stifle investment, and dampen jobs growth," she said.
