New data has shown that the Carbon Price has not had an impact on the cost of building materials for roads and bridges.
The Carbon Price was introduced in 2012 to encourage businesses to lower their pollution levels and it was considered possible that some companies might cover their costs by passing on these charges.
However, in a recent statement federal minister for infrastructure and transport, Anthony Albanese, pointed out that in the first nine months of the initiative, the cost of road and bridge building materials was smaller than the last decade's average.
The quarterly rise was 0.6 per cent, compared to an average of 1.1 per cent over the last ten years.
"We have not cancelled any projects and there has been no impact on the costs associated with delivering them. To the contrary, many projects are continuing to come in under-budget," Mr Albanese said.
"Construction costs are now rising at a slower pace than that recorded prior to the introduction of the Carbon Price."
These findings are contrary to Warren Truss' comments about the scheme, who said that it would add to road building costs and cause projects to be shelved.
