The Australian government will on Tuesday defend a class-action lawsuit brought by 23-year-old law student Kathleen O’Donnell who says the Australian Office of Financial Management and the Treasury are deceiving investors by not disclosing climate change alongside other financial risks in its exchange-traded debt. Al Jazeera reports that the case comes amid a surge in litigation from Europe to Mexico over the past five years as activists use the courts to pressure governments, companies and investors to act against global warming. Still, Australia’s government, a staunch supporter of the fossil-fuel export industry, has steadfastly rejected putting a price on carbon and is steering clear of the net-zero emissions goal that’s increasingly being adopted by countries around the world.
