An opportunity for New Zealand to show the world how to make the transition to a zero-carbon future

Sixty one businesses, making up nearly 50 percent of New Zealand's carbon emissions, have formed the Climate Leaders Coalition to help New Zealand transition to a low emissions economy.

They've committed to set carbon reduction targets and publish their performance against those targets.

Victoria University's Professor James Renwick says the coalition has the potential to make a significant difference.

He says they're talking the talk but the real question is whether they're going to walk the walk.

Renwick says we need to see what actual action these businesses are going to take.
