6 June 2019, The Conversation, Whichever way you spin it, Australia’s greenhouse emissions have been climbing since 2015. Let me explain how to see through the spin on Australia’s rising greenhouse emissions figures. With the release today of Australia’s emissions data for the December 2018 quarter, federal energy and emissions reduction minister Angus Taylor has been more forthcoming than usual about the rising trend in Australia’s emissions. There’s one small issue, though. Despite Taylor’s comments in which he sought to explain away Australia’s 0.7% year-on-year rise in emissions as a product of increased gas investment, actual emissions in the December quarter were in fact down relative to the September 2018 quarter. This is due mainly to the fact that people use much more energy for heating in the July-September period than they do during the milder spring weather of October-December. Taylor, meanwhile, was discussing the “adjusted” data, which reveals an 0.8% increase between the two quarters. This might all sound like minor quibbling. But knowing the difference between quarterly and annual figures, and raw and adjusted data – and knowing what’s ultimately the most important metric – is crucial to understanding Australia’s emissions. And it might come in handy next time you’re listening to a politician discussing our progress (or lack thereof) towards tackling climate change. Read more here
