April 23, 20218:58 AM UTC EnvironmentIndustry, green groups push Australia for action after it fails to adopt new emission targets Sonali Paul 4 minutes read Industry and green groups in Australia called on Friday for the government to step up action to cut carbon emissions after it failed to match ambitious new targets pledged by the United States and others at U.S. President Joe Biden's climate summit. Australia is the highest per capita carbon emitter among the world's richest nations, yet Prime Minister Scott Morrison made no pledge at the summit on Thursday to hit net zero by 2050. Nor did Morrison proffer any change to Australia's commitment under the Paris Agreement to cut its greenhouse gas emissions by 26% to 28% from 2005 levels by 2030, although speaking to media on Friday he left the door open to a new target.
