Australia is the most carbon-polluting nation in the world per capita, yet prime minister Scott Morrison may not attend the November landmark climate conference. He said he had not made any final decisions on attending, saying, ‘I have to focus on things here and with Covid. Australia will be opening up borders around that time. There will be a lot of issues to manage and I have to deal with those competing demands.’ Australia is expected to present its updated 2030 emissions cuts at the conference. It is one of the world's top exporters of coal and gas. Mr Morrison said he wants Australia to achieve net zero emissions ‘as soon as possible’, but he has not outlined any measures to do so and has not committed to net zero by 2050. A UN report ranked Australia last out of 170 member nations for its response to climate change.
