Tasmania is both at net-zero greenhouse gas emissions and gets 100% of its energy from renewable sources. The island off Australia reached net zero in 2015, because its vast forests and landscapes store more carbon than the state emits. In November 2020 it also became fully powered by renewable electricity, thanks to the island state’s wind and hydro-electricity projects. Having reached these feats, Rupert Posner and Simon Graham from ClimateWorks Australia explore what’s next for the island’s green journey. Getting to net-zero greenhouse gas emissions and 100% renewable energy might seem the end game for climate action. But what if, like Tasmania, you’ve already ticked both those goals off your list? Net-zero means emissions are still being generated, but they’re offset by the same amount elsewhere. Tasmania reached net-zero in 2015, because its vast forests and other natural landscapes absorb and store more carbon each year than the state emits. And in November last year, Tasmania became fully powered by renewable electricity , thanks to the island state’s wind and hydro-electricity projects. The big question for Tasmania now is: what comes next? Rather than considering the job done, it should seize opportunities including more renewable energy, net-zero industrial exports […]
