Robert McLachlan Nov 12, 2019

Two years into New Zealand’s Labour-led government, the long-delayed Zero Carbon Bill became law on 7 November. Passed essentially unanimously, the lengthy public debates and political manoeuvring faded away until the final passage was even anticlimactic: Flipping through the @nzstuff @DomPost I was starting to wonder if I’d dreamt the whole #zerocarbonbill thing.

Steve Trewick Aug 26, 2019
