The Australian government pledged on Tuesday to reach net zero emissions by 2050, ahead of the COP26 climate summit that begins this weekend in Scotland.

"At Glasgow I will confirm that Australia will continue to play our part. We will set a target to achieve net zero by 2050, and have a clear plan for achieving it," said Prime Minister Scott Morrison in an opinion piece published on his website.

The leader of Australia, one of the world's most polluting countries if its exports of fossil fuels are counted, said that neutral emissions will be achieved through investments in low-energy technologies such as hydrogen and low-cost solar, while supporting heavy industries such as mining to remain competitive.

"We will do this the Australian way. Through technology, not taxes," Morrison wrote, clarifying that his government however will maintain its target of reducing polluting emissions from 26 to 28 percent by 2030, compared to 2005 levels.
