As we approach the crucial Paris Climate Change meeting in December, it's worth reflecting on how far the world has moved in addressing climate change. It's a long-lived policy challenge, one that will take decades to fix and longer to measure success or failure. Sometimes we can be too negative in our perceptions when the reality is that we are making progress.
Here, most progress has come from the business sector. Ten years ago Business New Zealand found it hard to even use the word sustainability or address climate change seriously. Now it has spawned the Sustainable Business Council and is fully engaged in looking at our energy future.
Pure Advantage, set up by progressive business people, provides leadership by doing. Federated Farmers and Fonterra acknowledge the need to reduce emissions from agriculture and the sector is investing big in science - a long way from tractors being driven up the steps of Parliament by protesting farming leaders.
Greenpeace isn't just climbing chimneys but has made practical suggestions on how to configure a low carbon economy. New Zealand's youth is becoming more and more engaged. Generation Zero is leading the conversation on the future of our transport network.
Last month, I attended a business breakfast hosted by Air New Zealand. The chief executive acknowledged, as he should, that aviation was a big emitter and that biofuels were challenging. But he committed the company to becoming more fuel-efficient and to making business growth carbon neutral from 2020.
