CANBERRA, Australia—The Australian Parliament created landmark new laws Thursday that will make the nation’s biggest greenhouse gas polluters reduce their emissions or pay for carbon credits.
The center-left Labor Party administration said the so-called Safeguard Mechanism reforms are essential to Australia reaching its target of reducing its emissions by 43 percent below 2005 levels by the end of the decade and net-zero emissions by 2050.
Set to take effect on July 1, the reforms create a ceiling on the nation’s emissions and force Australia’s 215 most polluting facilities to reduce their emissions by 4.9 percent a year or reach the target with carbon credits.
The laws create Australia’s first price on carbon since a former Labor government created a carbon tax in 2012. A conservative government repealed that tax in 2014 and has since rejected any climate policies that would make polluters pay.
The bills passed the Senate on Thursday by a vote of 32 to 26, with Labor senators supported by the minor Greens party and unaligned legislators.
The Greens, who represent 11 senators, began negotiations with Labor with a demand that no new coal and gas extraction projects be allowed. But the Greens are satisfied that an agreement to strictly cap emissions would mean that half of the 116 new coal and gas projects proposed in Australia would not go ahead.
The Liberal Party and the Nationals party, which formed the conservative coalition government that was voted out of office in 2022 after almost a decade in power, opposed the legislation.
Opposition climate change and energy spokesperson Ted O’Brien said capping emissions would drive Australian industrial investment offshore to China and India while increasing costs for Australians.
“This is a tax that will see prices go up in the midst of a cost of living crisis where every household across this country is feeling the pain of prices going up,” O’Brien told Parliament, referring to unusually high inflation and interest rates in Australia.
The government argues that without the mechanism, Australia would only reduce its emissions by 35 percent by the end of the decade.
Emissions won’t be able to exceed Australia’s current pollution level of 140 million metric tons (154 million US tons) a year, and that cap will decrease over time. Big polluters would be able to buy carbon credits to help achieve their emission reduction targets, but polluters that use carbon credits to achieve more than 30 percent of their abatement would have to explain why they were not doing more to reduce their own emissions.
The reforms would reduce Australia’s greenhouse gas emissions by 205 million metric tons (226 million US tons) by 2030, equivalent to taking two-thirds of Australia’s cars off the road in the same time, the government said.
The conservative parties created the Safeguard Mechanism when they were in power in 2016. But the emission limits were so high that the 215 major polluters, which account for almost 30 percent of Australia’s emissions, were able to increase their emissions by 4 percent.
Prime Minister Anthony Albanese said his party was voted into power at 2022 elections to take action on climate change.
“Today’s a big step toward repaying that faith,” Albanese told Parliament. “Passing this legislation has put Australia on a realistic path to net-zero emissions by 2050 and a 43 percent reduction by 2030.”
The previous government had set a less ambitious target of reducing Australia’s emissions by 26 percent to 28 percent below 2005 levels by 2030.
The Climate Council, a leading climate communicator, described the reforms as the first Australian legislation in a decade that would regulate greenhouse gas pollution.
The Australian Petroleum Production and Exploration Association, which represents oil and gas producers, said the reforms make it harder for gas to be used to transition Australia away from more harmful coal and provide reliable backup for renewable energy.
The House of Representatives, where Labor holds a majority of seats, passed Senate amendments 89 votes to 50 later Thursday. The House had passed the original draft of the laws on Monday.
