New Zealand's largest exporter, Fonterra, says it will receive no protection under planned changes to the emissions trading scheme.

Air NZ chief executive Rob Fyfe has lashed out at dithering over cutting emissions, described climate talks as a 'bureaucratic circus'.

Labour and National should put aside their egos and resume ETS talks for the betterment of the country, says United Future leader Peter Dunne.

The cost to taxpayers of the Government's ETS scheme could be four times more than predicted, says Phil Goff.

Business lobby groups welcomed proposed changes to the emissions trading scheme agreed by the Government and the Maori Party yesterday.

The Maori Party has come to the Government's aid to get a new emissions trading scheme (ETS) in place.

A Govt and the Maori Party deal on emissions trading legislation will halve the impact on power and petrol prices over the first two years of the scheme.
