The fifth session of the United Nations Intergovernmental Negotiating Committee to develop an international legally binding instrument on plastic pollution (INC-5) ended without a treaty in Busan, South Korea, in the early hours of the morning. The more than 100 countries participating in what was to be the final round of negotiations have agreed to continue negotiating, reports Reuters.
If practices and public policies do not change, the mass of mismanaged plastic waste in the world will double to 121 million tonnes per year by 2050, according to a study published in Science. The article also assesses the potential impact of global measures, such as those envisaged by the forthcoming UN global treaty on plastic pollution, which begins its final negotiating session at the end of this month.
More than 52 million tonnes of plastic waste are emitted around the world every year, according to a study published in Nature that inventories plastic pollution in 50,702 cities. It concludes that littering is the largest source of plastic emissions in the global North, and uncollected waste is the largest source in the South.
A spill of plastic pellets from containers from the merchant ship Toconao has reached several areas of the Galician coastline. For its part, the Government of Asturias has upgraded the Accidental Marine Pollution Plan to phase 2 due to the detection of microplastics on the coast.
Most so-called compostable plastics require specific conditions to degrade that are only obtainable in industrial settings, warns a study published in the journal PLoS One. Polylactic acid - a polymer obtained from natural renewable sources that is used as an alternative to petroleum-based plastics - takes more than a year to degrade in a marine environment, compared to 35 days for natural cellulose fibres, according to the analysis, which combines observations in waters off the coast of California (US) with laboratory measurements.
The deadline passed and after two marathon nights of meetings, the delegations of the UN member states have managed to reach an agreement to make the so-called Oceans Treaty - or BBNJ Treaty, Biodiversity Beyond National Jurisdiction - a reality. New York City has seen the fifth session of this conference bear fruit with an agreement on the wording of the text, seventeen years after the talks began and with negotiations stalled last August due to a lack of agreement. The Treaty aims to protect and regulate the use of areas beyond national jurisdiction, which account for more than 60% of the oceans, or almost half of the planet. Marine genetic resources and how to share these benefits has been one of the main stumbling blocks.
