Australia's environment minister said Tuesday her government will lobby against UNESCO adding the Great Barrier Reef to a list of endangered World Heritage sites, arguing that criticisms of government inaction on climate change were outdated.
Officials from the U.N. cultural agency and the International Union for Conservation of Nature released a report on Monday warning that without "ambitious, rapid and sustained" climate action, the world's largest coral reef is in peril.
The report, which recommended shifting the Great Barrier Reef to endangered status, followed a 10-day mission in March to the famed reef system off Australia's northeast coast that was added to the World Heritage list in 1981.
Environment Minister Tanya Plibersek said the report was a reflection on Australia's previous conservative government, which was voted out of office in May elections after nine years in power.
She said the new center-left Labor Party government has already addressed several of the report's concerns, including action on climate change.
"We'll very clearly make the point to UNESCO that there is no need to single the Great Barrier Reef out in this way" with an endangered listing, Plibersek told reporters.

"The reason that UNESCO in the past has singled out a place as at risk is because they wanted to see greater government investment or greater government action and, since the change of government, both of those things have happened," she added.
The new government has legislated to commit Australia to reducing its greenhouse gas emissions by 43 percent below the 2005 level by 2030.
The previous government only committed to a reduction of 26 percent to 28 percent by the end of the decade.
Plibersek said her government has also committed 1.2 billion Australian dollars ($798 million) to caring for the reef and has canceled the previous government's plans to build two major dams in Queensland state that would have affected the reef's water quality.
"If the Great Barrier Reef is in danger, then every coral reef in the world is in danger," Plibersek said. "If this World Heritage site is in danger, then most World Heritage sites around the world are in danger from climate change."
The report said Australia's federal government and Queensland authorities should adopt more ambitious emission reduction targets in line with international efforts to limit future warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit) since pre-industrial times.
The minor Greens party, which wants Australia to slash its emissions by 75 percent by the end of the decade, called for the government to do more to fight climate change in light of the report.
Jodie Rummer, a marine biologist at James Cook University in Townville who has worked on the reef for more than a decade, supported calls for Australia to aim for a 75 percent emissions reduction.
"We are taking action, but that action needs to be much more rapid and much more urgent," Rummer told Australian Broadcasting Corp.
"We cannot claim to be doing all we can for the reef at this point. We aren't. We need to be sending that message to the rest of the world that we are doing everything that we possibly can for the reef and that means we need to take urgent action on emissions immediately," she added.
Feedback from Australian officials, both at the federal and state level, will be reviewed before Paris-based UNESCO makes any official proposal to the World Heritage committee.
In July last year, the previous Australian government garnered enough international support to defer an attempt by UNESCO to downgrade the reef's status to "in danger" because of damage caused by climate change.
The Great Barrier Reef accounts for around 10 percent of the world's coral reef ecosystems. The network of more than 2,500 reefs covers 348,000 square kilometers (134,000 square miles).
Australian government scientists reported in May that more than 90 percent of Great Barrier Reef coral surveyed in the latest year was bleached, in the fourth such mass event in seven years.
Bleaching is caused by global warming, but this is the reef's first bleaching event during a La Niña weather pattern, which is associated with cooler Pacific Ocean temperatures, the Great Barrier Reef Marine Authority said in its annual report.
Bleaching in 2016, 2017 and 2020 damaged two-thirds of the coral.
Coral bleaches as a response to heat stress and scientists hope most of the coral will recover from the latest event.
