4 December 2024 - The UN Intergovernmental Negotiating Committee meeting in Busan, South Korea, was supposed to be the fifth and final round of negotiations to produce the first legally binding treaty on plastic pollution, including in the marine environment, by the end of 2024. However, it concluded in early December 2024 without an agreement, leaving countries with an extended deadline and a proposal by the Chair to resume talks at an additional session (INC 5.2) in 2025 to resolve outstanding disagreements. Countries will use the latest version of the Chair’s text as the basis for the continued negotiations.

Plastic production & global warming

At the heart of the discussions was whether the treaty would include limits on plastic production. Over 100 nations, including small island states, African countries, and several European and developing nations like Norway and Mexico, along with the EU, supported a proposal to set a global target for reducing plastic production. Many have emphasized that this is essential to address chemicals of concern. However, for some plastic-producing and oil and gas countries, such a proposal crossed a red line.

The plan of petrochemical states to maintain plastic production growth threatens to derail global climate goals. Every year, the world produces more than 360 million tonnes of new plastic. Plastic production is on track to triple by 2050. Scientists estimate that a 75% reduction in plastic production is needed by 2040 to keep global warming to 1.5°C. Without such cuts, plastic production alone could consume up to 31% of the world’s remaining carbon budget to stay within that critical temperature threshold.

Plastic & health

The economic burden of health impacts is growing. Research by the Endocrine Society revealed that merely four groups of plastic-related chemicals are responsible for health expenses exceeding $400 billion annually in the United States. On a global scale, the UN Environment Programme cautions that failing to address chemical and plastic pollution could result in costs reaching as high as 10% of the world’s GDP.

Microplastics have been found in air, fresh produce, and even human breast milk. In animals, such as fish, these broken-down bits of larger plastics have been linked to lower levels of growth and reproduction, among other issues. Researchers are still working to determine more conclusively whether microplastics pose a direct risk to human health, and if so, at what level.

Finance

Another key area of contention was the financial support for developing country parties. At least 126 countries have called for an independent, dedicated fund to assist with treaty implementation. However, the Chair’s draft weakened this demand, and this is one of the issues will be furthered discussed at INC-5.2 – as well as the proposal of establishment of a polymer production fee, a widely supported mechanism for funding global action.
