We're on our way to zero in 2050. This is the week when Extinction Rebellion promised to blockade Heathrow airport but didn't, the week when Heathrow airport opened consultation on its plans for a new third runway, and the week when outgoing prime minister Theresa May pledged to reduce the U.K.'s carbon emissions by not 80%, but by a full 100% by 2050. Net zero emissions! Is there more to life than GDP and growth? There is in New Zealand. And how should we talk about all these sustainability issues? All this and more in your weekly helping of sustainability news.
