Over 100 businesses, including some of the country's biggest, have signed up to the year-old Climate Leaders' Coalition.
60 businesses including Z Energy, Fonterra, Air New Zealand, Kiwi Rail, Ngai Tahu Holdings, Spark, Vector and Westpac formed the coalition a year ago.
By signing up, they committed to measuring and reporting their emissions to align with the Paris Agreement.
That number has now grown to 107, representing 60 per cent of the country's gross carbon emissions.
Kathryn asks Climate Leaders Coalition convenor and CEO of Z Energy Mike Bennetts, what's really been achieved.
