We have a belated Cop16 agreement to protect biodiversity – but is it enough?

Patrick Greenfield Patrick Greenfield
 

Last week, countries signed off a hard-won compromise on nature finance after marathon negotiations in Rome, finally bringing biodiversity Cop16 meetings to an end. In November, the UN nature summit was suspended in disarray after negotiators ran out of time to complete their work in Cali, Colombia. They needed another meeting in Rome to finish the job.

In Italy, governments agreed a roadmap to find the much-needed $200bn (£155bn) a year for nature between now and 2030, including discussions over a new fund for biodiversity – a key negotiating demand of many countries in the global south. They also signed off indicators against which states will measure their progress in Armenia at the end of 2026.

The few ministers in attendance were quick to frame it as a success. Cop16’s president, Susana Muhamad, Colombia’s outgoing environment minister, wept at the conclusion of a “historic day”.

Steven Guilbeault, Canada’s minister of environment and climate change, said: “Our efforts show that multilateralism can present hope at a time of geopolitical uncertainty.”

But, in private and increasingly in public, there is growing concern that the 2020s are going to be another decade of failure on nature. Governments have never met a single UN target on biodiversity. The chance of yet another repeat is growing: the 23 targets and four goals agreed on less than three years ago in Montreal are already on life support.

More, after this week’s most important reads.

In focus

Coquerel’s sifakas in Madagascar

Ahead of talks in Rome, analysis by Carbon Brief and the Guardian found that more than half the world’s countries have no plans to protect 30% of land and sea for nature, despite committing to a global agreement to do so in 2022. It is the headline target for this year’s agreement. If large, biodiverse countries like Mexico, Indonesia, Malaysia, Peru, the Philippines, South Africa and Venezuela do not implement it, the global target will not be met.

Subsidies that drive global heating and destroy nature have continued to rise despite a target to reform $500bn of the most harmful by the end of the decade, according to a report by Earth Track last year. Only Brazil and the EU were showing signs of action, according to the researchers.

Both are issues that predate Trump and the recent change in geopolitical winds on the environment.

Meanwhile, scientific indicators continue to worsen. Global wildlife populations have plunged by an average of 73% in 50 years, according to the latest Living Planet Index. We will get a better idea of progress on other targets at Cop17 next year, but some environment ministers are increasingly speaking up about the lack of progress.

Asked whether enough was being done to reach the overarching ambition of halting nature loss by 2030 by my colleague Phoebe Weston in Rome, Madagascar’s environment minister Max Fontaine painted a bleak picture.

“Honestly, it’s almost impossible when you see the trends of where things are going,” he said. “We are not going in the right direction, we all need to strengthen efforts.”

Jean-Luc Crucke, Belgium’s climate and ecological transition minister described the Cop negotiations as the “least bad” process. If we really want to save nature, he said, “there is no other solution than this one”. But questions are being raised about its relevance. Ahead of the Rome summit, there were concerns that not enough countries would turn up at the UN nature summit for negotiators to make binding decisions.

Of course, there have been some small victories. In Cali, governments reached an agreement to encourage companies to share commercial profits from discoveries using genetic data from nature through the creation of a voluntary fund, which was launched in Rome. We will have to wait and see how much money the new fund ends up generating. Countries also formally recognised Indigenous communities in the global decision making process on biodiversity.

It is not over until it is over. But if there is another decade of missed targets on nature, harder questions will be asked about the utility of negotiating international agreements that countries have no apparent ability or will meet.

The change I made – Growing my own salad

Down to Earth readers on the eco-friendly changes they made for the planet

Lettuce seedlings in an organic vegetable garden.

“I started growing my own salad due to the abysmal quality and price of the salad bags in the supermarket, which go slimy a day or so after opening,” reader Lyn Wills has told us.

Along with lettuce leaves, Wills has mastered beetroots, rocket and chives, which reliably come back every year. “I have a very small space which is sunny enough, and I just grow and pick what I need. It’s worked well for me.”

Recent ventures into fruit have also … borne fruit, Wills adds. “I have some raspberry canes and it’s great having these fresh for breakfast – though this year there have been hardly any blackcurrants which I miss as these are rarely in shops.”

As well as being good for the environment, it’s proved good for Wills’ wallet – she finds that having more fresh options at home stops her heading to the shops so often.

Creature feature – Yangtze finless porpoise

Profiling the Earth’s most at-risk animals

Two Yangtze finless porpoises at the Yichang section of the Yangtze River in central China’s Hubei province.

Population: Approximately 1,000
Location:
Yangtze River, China
Status: Critically endangered

It is feared that the Yangtze finless porpoise, with a population of between 1,000 and 1,800, will go the same way as its extinct cousin the Baiji dolphin. Relocation of some animals to secure reserve in the last decade has perhaps secured the future of the species known for their cheeky smiles and high level of intelligence, with reports from China showing that some pairs have recently been filmed in their natural habitat of the Yangtze River.

The Guardian’s Mark Brown and photographer Christopher Thomond were lucky enough to join a group of Yorkshire volunteers in cleaning out one of the UK’s deepest canal locks.

Knee deep in gunk and all sorts of lost artefacts, Thomond captured group leader Matt Crowley (above, in yellow) and more of the Canal and River Trust volunteers in Tuel Lane lock, on the Rochdale canal in West Yorkshire.
