The Tasmanian Climate Collective's submission to the Senate Inquiry into information integrity on climate and energy details how fossil-fuel-funded disinformation, from historical climate hijacking campaigns to misleading offshore wind and whale claims and nuclear power narratives, has delayed climate policy and eroded public trust. It recommends government-funded public education and prebunking campaigns to build resistance to misinformation, participation in international initiatives such as UNESCO's Global Initiative for Information Integrity on Climate Change, and stronger regulatory and legal consequences for organisations and media platforms that knowingly amplify climate disinformation or greenwashing.
