Away from the cameras and fanfare of the Third UN Ocean Conference under way in the coastal French city, they voiced a shared determination to finalize this year a global treaty that could, for the first time, regulate plastics across their entire life cycle.

“There is renewed commitment to conclude the treaty in August,” Jyoti Mathur-Filipp, who attended the meeting and is leading the treaty negotiations, told UN News. “This is too urgent an issue to be left for the future.”

Hosted by Inger Andersen, the head of the UN Environment Programme (UNEP), the informal gathering marked a quiet but significant diplomatic moment – a sign that after two years of deliberations, political momentum may finally be catching up with scientific alarm.

With one round of talks remaining – scheduled from August 5 to 14 in Geneva – negotiators are now under pressure to deliver the first legally binding treaty aimed at tackling plastic pollution across production, consumption, and waste.

A crisis accelerating in plain sight

Plastic waste has infiltrated nearly every ecosystem on Earth, and increasingly in the form of microplastics – the human body. Without urgent action, the amount of plastic entering the ocean each year could reach 37 million metric tons by 2040, according to UN estimates.

“We are choking with plastic,” Ms. Mathur-Filipp said. “If we do not do something to tackle plastic pollution, we will not have a single ecosystem left, whether it’s terrestrial or marine.”

The economic toll is no less staggering. Between 2016 and 2040, the projected cost of plastic-related damage could reach $281 trillion. “It is costing the economy a lot,” said the Indian native. “In tourism, in beach clean-up, in lack of fish for fishing folk, coastal damage, wetlands damage.”

The final stretch in Geneva

The treaty process was launched in 2022, at the request of the UN Environment Assembly, the world’s highest decision-making body on environmental issues. Since then, the Intergovernmental Negotiating Committee (INC) has convened five times in less than two years – an unusually rapid timeline by UN standards.

“We have had five sessions very rapidly from December of 2022 to December of 2024,” said Ms. Mathur-Filipp, who serves as the INC’s Executive Secretary. She hopes the upcoming session this August in Geneva will mark the treaty’s conclusion.

A key breakthrough came six months ago at the last round of talks in Busan, South Korea, where delegates produced a 22-page “Chair’s text,” outlining the draft treaty’s basic structure.

“It has 32 or 33 articles in it, with names of articles, so countries can now start seeing what this treaty will look like,” she explained. “They have started speaking with article numbers for negotiation… and this is why my hope is that there would be a conclusion.”

A treaty with teeth – and flexibility

While the draft treaty is still under negotiation, it includes measures that would target the entire life cycle of plastic – from upstream production to downstream waste. It reflects both mandatory and voluntary provisions, in line with the original UN mandate.

The current draft also includes the institutional architecture of a typical multilateral treaty: the ratification process, governance rules, and proposed implementation bodies.

“It has an objective. It has a preamble,” said Ms. Mathur-Filipp. “It looks like a treaty.”

If all goes according to plan, the final text will be submitted to a diplomatic conference – later this year or in early 2026 – where governments can formally adopt it and begin the ratification process.

Unequal burdens, global stakes

Although plastic pollution is a global issue, some countries – especially small island developing states – bear a disproportionate burden.

“It is a fact that small island developing states are not the ones that are using plastic as much as what’s flowing onto their shores and therefore, they become responsible for beach clean-up, which is not their doing,” Mathur-Filipp said. “They are unfairly impacted.”

An estimated 18 to 20 per cent of global plastic waste ends up in the ocean.

One diplomat’s mission

Before leading the INC, Ms. Mathur-Filipp worked at the UN Convention on Biological Diversity, where she helped shape the landmark Kunming-Montreal Global Biodiversity Framework, the 2022 agreement to protect 30 per cent of the planet’s land and ocean by 2030. The challenge of managing a fast-moving, high-stakes negotiation is familiar terrain.

“I wasn’t tired enough there, so now I’m doing this,” she said.

As the Mediterranean UNOC3 host city plays its part in building momentum, all eyes will, in the weeks ahead, turn to Geneva. The outcome in August could determine whether the world takes a decisive step toward curbing the plastic crisis – or allows it to deepen, unchecked.
