Mike Casey - CEO, NZ Zero

Mike is CEO of NZ Zero (NZ0.com) a company that specialises in producing food without the use of any fossil fuels. Mike founded NZ Zero after successfully establishing Forest Lodge, a cherry orchard that he believes to be the first zero fossil fuel farm in the world (well in modern times anyway!). The first cherries were sold this year in Farro Fresh supermarkets in Auckland, and showed that consumers were willing to pay a 10-15% climate premium for their food.

NZ0 is now looking to covert other growers and farmers. We can change our behaviour in many ways to help the climate but one thing we cannot do is stop eating. New Zealand must become the most climate friendly food producer in the world to continue to have our edge in the international market.
