'Zero tolerance' plan eyed for plastic pollution

From BBC - November 30, 2017

A plan for zero tolerance of plastic pollution of the oceans may be agreed by nations at a UN environment summit.

Governments are being asked to move towards a legal treaty banning plastic waste from entering the sea.

At the moment ships are prohibited from dumping plastic overboard but there's no international law against plastics flooding into the sea from the land.

Experts say ocean plastics are an obvious subject for a global treaty: plastics present a large-scale threat.

Plastic pollution does not recognise international borders.

Delegates in Nairobi preparing the way for the UN's environment ministers meeting next week are said to be in broad agreement on the need for tougher action to combat the plastics crisis.

They are setting up a working party to explore options for global action to tackle plastic waste and microplastics.

The US has volunteered to take part, but is traditionally resistant to agreeing any international laws.

Mirror, mirror

One idea is to mirror the model of the Paris climate agreement.

In that deal, the framework of reporting emissions cuts and agreeing long-term goals is legally binding - but the national actions themselves are voluntarily determined.

Environmentalists say getting better information on how much plastic is flowing into the sea from what sources would be a major step.

The UN has already committed to substantial reduction of plastic waste by 2025 but a resolution led by Norway says the long-term aim must be for zero plastic waste.

It also wants to clean up of existing plastic from beaches. It says this is better value for money and better for the environment than some of the large-scale clean-up experiments currently in the mid Pacific - which it fears may harm wildlife.

Cleaning up beach plastic is especially important, it says, because abrasion breaks down large plastics into very harmful microplastics.

Cautious progress?
