Business lobby groups say slowing the implementation of the Emissions Trading Scheme would be a good move.
A review of the Government's scheme is recommending the implementation of the scheme be slowed down.
Currently sectors in the scheme step up to a full obligation in 2013, but a review of the ETS suggests phasing that in until 2015 - a move which will cost $455 million over three years.
Business New Zealand chief executive Phil O'Reilly says the review does not properly take into account the costs being lumped on businesses and communities at a time of economic uncertainty, and a slower pace make sense.
Environmental advocates are critical of the delay.
