Something I've tried hard to do here is always play the ball, not the person. I came here to protect the environment, not to play petty politics. I've given speeches that have gone viral, but I'm proud I've never resorted to name calling or cheap blows or insults. For 20 years now, I've campaigned for climate action, because this danger is the greatest challenge of our age. I focused here on keeping fossil fuels in the ground and encouraging clean energy. My proudest achievement was, after years of work, being part of the historic ban on offshore oil exploration. I helped negotiate the ends of tens of millions of dollars in fossil fuel subsidies, and, alongside who I call New Zealand's Erin Brockovich—Taranaki farmer Sarah Roberts—we uncovered scandalously light-handed fracking rules, and bringing that to the light of day led to serious improvements.
