Countries from around the world set their sights on a pivotal deal to curb plastic waste, a source of long-term pollution and worsening contamination of the ocean’s food chain.

The UN wants individual countries to sign up to “significantly” reduce plastic production, including a phasing out of single-use plastics by 2030 — a goal inspired by the 2015 Paris Agreement on voluntary reductions of carbon emissions.

A landmark report due to be out this week is expected to ram home the warning of the threat to ecosystems from rampant plastic and chemical waste.

The world currently produces more than 300 million tonnes of plastics annually, and there are at least five trillion plastic pieces floating in our oceans. Microplastics have been found in the deepest sea trenches and high up the earth’s tallest peaks, and plastic consumption is growing year-on-year.

UN reports

Plastic is a very good material, it’s durable, flexible and light which means we should make the best out of it for as long as possible instead of disposing of it.”

The Nairobi meeting comes against the backdrop of series of UN reports outlining in stark terms the damage mankind is doing to the planet, much of it due to reckless consumption.

The One Planet Summit on will bring together heads of State, including French President Emmanuel Macron and Kenyan counterpart Uhuru Kenyatta to lend political clout to the process.
