In a last-minute commitment after months of debate, the Australian government has promised to reach net zero emissions by 2050, expecting to meet the goal largely through technology development.

The move comes following international pressure as Australia had previously refused to join countries in pledging to meet the target ahead of the United Nations' COP26 climate conference in Glasgow.

However, the plan unveiled on Tuesday (October 26), which includes a government investment of AU$20 billion, does not strengthen the target set for 2030, with Prime Minister Scott Morrison saying Australia is on track to beat its Paris Agreement goal, cutting emissions by 30 to 35 percent by that decade.

"We will do this the Australian way," Morrison said ahead of a press conference, announcing investments in new energy technologies like hydrogen and low-cost solar.

An Australian hydrogen industry could be worth more than AU$50 billion in 2050, according to the government. Meanwhile, expanding production and processing of metals like lithium, nickel, copper and uranium could together be worth around AU$85 billion in exports in 2050.

That said, Australia will continue to be heavily dependent on fossil fuels as the plan will not shut down coal or gas production. The country is a major coal player, with the third largest reserves in the world, but its reliance on coal-fired power makes it one of the world's largest carbon emitters per capita.

"We want our heavy industries, like mining, to stay open, remain competitive and adapt, so they remain viable for as long as global demand allows," Morrison said. "We will not support any mandate — domestic or international — to force closure of our resources or agricultural industries."

Australia's desire to achieve net zero emissions by 2050 is a step in the right direction, Prakash Sharma, Wood Mackenzie's Asia Pacific head of markets and transitions, said.

"Our analysis shows that Australia can reach net zero emissions by 2050," he said. The country's major trading partners — China, Japan and South Korea — are already in transition towards that goal.

According to Wood Mackenzie, nearly 83 percent of Australia's power generation will come from solar and wind by 2050, as compared to about 20 percent last year. Natural gas, bio energy, geothermal and small modular reactors will supply the remaining 17 percent in power output. Coal into power is expected to be phased out by 2035.

"Although the pathway requires complete transformation of its traditional energy and export sectors, there are significant opportunities to capitalise on and protect future revenues," Sharma said.

"This will require Australia to become a significant player in low-carbon hydrogen trade as well as being able to offer carbon storage and offset services."

Meanwhile, the Australian Conservation Foundation has welcomed the prime minister's commitment to reach net zero by 2050, but said the mid-century goal is only meaningful with deep cuts to climate pollution this decade.

"Unless the government sets the wheels in motion to cut our emissions in half by 2030, it is making climate change worse and turning its back on the opportunities," said Chief Executive Kelly O'Shanassy.

"Australia can become a global clean energy superpower in the next decade by replacing coal and gas with renewable energy," she added. "We have abundant clean energy, tools and talent, but we cannot delay any longer."
