Auckland mayor Phil Goff says meeting the council’s goal of halving carbon emissions by 2030 is “tough but achievable,” Stuff reports. The mayor said the major factors are the bulk of new housing being inside existing urban limits, major new public transport projects, and the eventual end of the production of petrol and diesel vehicles. Meanwhile, Paul Winton, an engineer and analyst who founded the 1.5 Project, has labeled Goff’s claim as a “smokescreen” that gives the impression that action is happening on the scale required.
