The bleak outlook was laid out in the Institute of Public Affairs' Net Zero Jobs document. The IPA is a conservative think-tank based in Melbourne. The document uses data from the National Greenhouse Gas Inventory by Economic Sector report, along with industry employment data from the Australian Bureau of Statistics, to estimate how many jobs would be put at risk from a net zero emissions target. It claimed that up to 653,600 jobs would be directly in the firing line from a net zero emissions target. But Labor spokesman for Northern Australia Murray Watt has rubbished the claims as a "blatant scare campaign from a fringe group".
