It comes as the US president will speak to other world leaders, including Boris Johnson, at a global climate summit held at the White House on Thursday, according to Sky News.
The pledge – which amounts to nearly doubling previous commitments – and the summit represent a concerted US effort to reclaim credibility and leadership on climate change after four years of inaction under Donald Trump.
Among measures that could be employed to reduce emissions by 50% to 52% is a “carbon border adjustment” – or carbon tariff – that would tax imports from countries that do not have similar emissions controls.
Writing for The Guardian, Adam Morton said Although the Morrison government has promoted a “technology not taxes” approach to emissions reduction to convince allies that Australia is serious about making the transition, a senior Biden administration official told reporters Australia could not rely on technology alone to reach net-zero emissions by 2050.
Joe Biden has promised to use the summit of 40 world leaders, which starts at 10 pm eastern Australian time, to announce a short-term emissions reduction target, and called on other countries to do the same.
The United States is expected to set a goal of cutting emissions roughly in half over the next 10 years.
It follows the European Union confirming a goal of a 55% cut by 2030 compared with 1990 levels, and Britain planning a 78% cut by 2035.
Writing for Reuters, Reuters null said Johnson will address the opening session of a U.S.-led climate change summit hosted by U.S. President Joe Biden, who has invited dozens of world leaders to the virtual event.

It comes days after China and the United States agreed that stronger pledges were required to tackle climate change.
On Tuesday, Johnson said Britain would cut carbon emissions by 78% by 2035 in what he hailed as the world’s most ambitious climate change target that would put the country on track to become a net-zero producer.
