The Chair of the Climate Change Commission is correcting the cost of his recommendations, after he said on Monday projected costs would shave off one percent of GDP growth each year.

Carr told RNZ that GDP growth would hypothetically go down from three percent to two percent if the recommendations were put into practice.

Carr has now corrected himself, saying the cost of the recommendations to the New Zealand economy is estimated to be much less, at one percent of the overall size of the economy.

He told Heather du Plessis-Allan that they are talking about the level of the economy will be one percent lower in a low emissions stage, based on current forecasts. 

And he confirmed that the rate of growth will remain the same. 

Carr says he thought he was talking about levels, not the GDP growth

"We are certainly willing to be corrected."

He says that the annual rate of GDP growth for the next 30 years will be 1.85 percent if the recommendations are put into force.
