As New Zealand moves closer to landmark legislation to curb carbon emissions, a top Australian Earth System Scientist, Will Steffen, says more needs to be done to change the economic systems to drive long lasting change on a global level. He says New Zealand's biggest challenge is agriculture, but if it can crack how to get those emissions down that knowledge could be exported.
Will Steffen is an Emeritus Professor from the Australian National University.From 2004 to 2011 he served as science adviser to the Australian Government Department of Climate Change and from 2011 to 2013 was a Climate Commissioner on the Australian Government's Climate Commission.
