Unesco recommends Great Barrier Reef world heritage site should be listed as ‘in danger’

The Great Barrier Reef should be placed on to a list of world heritage sites that are “in danger”, according to a recommendation from UN officials that urges Australia to take “accelerated action at all possible levels” on climate change.

The United Nations Educational, Scientific and Cultural Organization says the world’s biggest coral reef system should be placed on the list at the world heritage committee meeting next month.

The recommendation has sparked a flurry of activity from the Australian government, with the environment minister, Sussan Ley, saying she had already joined the foreign affairs minister, Marise Payne, in a call to Unesco’s director general, Audrey Azoulay.

If the committee followed the recommendation, experts said it would be the first time a natural world heritage site has been placed on the “in danger” list mainly because of impacts from the climate crisis.

Global heating caused by fossil fuel burning has driven ocean temperatures higher, leading to three mass bleaching events on the 2,300km reef since the last time it was assessed by the committee in 2015.

Ley said the government would “strongly oppose” the recommendation, claiming officials had been “stunned” by what she described as a “backflip on previous assurances” by UN officials the step would not be taken this year.

Unesco recommends Great Barrier Reef be listed as ‘in danger’; Australian government says it will ‘strongly oppose’ the listing

World heritage sites are global icons and “in danger” listings are usually recommended after effects from armed conflict and war, pollution, poaching and uncontrolled urbanisation.

The Unesco report says a revision of Australia’s key reef policy – the reef 2050 plan – should “fully incorporate” conclusions from a major government review that “accelerated action at all possible levels is required to address the threat from climate change”.

The report said despite efforts and achievements by the state and federal governments, key targets on improving water quality had not been met.

“The plan requires stronger and clearer commitments, in particular towards urgently countering the effects of climate change, but also towards accelerating water quality improvement and land management measures,” it said.

Ley said the recommendation followed “a complete subversion of normal process”. She said officials had been reassured a week ago that Unesco would not be recommending the reef be placed on the “in danger” list.

The government suspects China may have played a role in the latest recommendation. It chairs the World Heritage Committee and will host a meeting on 16 July at which the draft recommendation will be considered.

Ley said climate change was the biggest threat to the reef but the world heritage committee was “not the forum” to “make a point” about climate change.

“This decision was flawed and clearly there was politics behind it, and that has subverted the proper process. For the World Heritage committee not to foreshadow this listing is appalling,” she told reporters on Tuesday.

She said there were more than 80 world heritage properties that Unesco had identified as under threat from climate change. The government may have understood if the body decided to list all of them as “in danger”, but it had singled out the reef, she said.

“When procedures are not followed and the process is turned on its head and the assurances my officials received have all been upended at the last minute, what else can you conclude … that this is politics.”

Ley had called Azoulay overnight, saying: “I made it clear that we will contest this flawed approach, one that has been taken without adequate consultation.

“This sends a poor signal to those nations who are not making the investments in reef protection that we are making.”

It is the second time the reef has faced the threat of an in danger listing. The last time, in 2015, the government embarked on a successful lobbying effort to pressure the 21-country committee.

Unesco is also recommending that a monitoring mission be launched to develop “corrective measures”, asking the Queensland and federal governments to submit a report by February 2022 outlining new steps to protect the reef.

The conservation groups WWF-Australia and the Australian Marine Conservation Society have lobbied members of the committee before the reef decision, asking them to pressure Australia to take stronger action on cutting greenhouse gas emissions.

A consultant to the AMCS, Imogen Zethoven, said Australia’s climate policies were “more consistent with a 2.5-3.0C rise in global average temperature – a level that would destroy the Great Barrier Reef and all the world’s coral reefs.”

She said the Australian government’s inaction had led the reef to the brink of the “in danger” listing.

Richard Leck, head of oceans at WWF-Australia, said Australians would be shocked by the Unesco recommendation but it was “a powerful message” that the government needed to “lift its game” on climate change.

Australia’s greenhouse gas emissions targets have not changed since 2015 and the prime minister, Scott Morrison, has resisted international pressure to adopt a firm net zero target by 2050.

Assoc Prof Scott Heron, of James Cook University, has led a study on the effects of climate change on world heritage reef sites. He said the recommendation was a “surprise” but “also not completely unexpected.”

“These cards have been stacking up over the past years,” he said.

The Labor leader, Anthony Albanese, said the threat of an “in danger” listing for the reef came as the return of Barnaby Joyce as Nationals’ leader made the government less likely to commit to a target of net zero greenhouse gas emissions by 2050.

“The whole of the G7, every state and territory government, every major business in Australia, the Business Council of Australia, the National Farmers’ Federation have all committed to it,” he said. “The election of Barnaby Joyce just sends the wrong message.”

The Greens leader, Adam Bandt, said the government had to choose between coal or the reef.

“You can’t have both,” he said. “If the world heats up over 1.5C [compared with pre-industrial levels], the reef will die. The only party in Australia with climate targets in line with 1.5C is the Greens.”
