Plastic packaging generates significant negative externalities,

conservatively valued by UNEP at $40 billion and expected to increase with strong volume growth in a business-as-usual scenario.

Each year, at least 8 million tonnes of plastics leak into the ocean.
If no action is taken, this is expected to increase to two per minute

by 2030 and four per minute by 2050.

Plastic packaging represents the major share of this leakage.

Plastics in the Marine Environment

SLIDE 14

There are over 150 million tonnes of plastics in the ocean today. In a business-as-usual scenario, the ocean is expected to contain 1 tonne of plastic for every 3 tonnes of fish by 2025, and by 2050, more plastics than fish (by weight).

Solving the Problem: Breaking the Supply Chain Enhanced recycling/reuse Degradable polymers Education But in the meantime….

SLIDE 19

Solving the Problem: Breaking the Supply Chain

The largest source of marine debris is most likely litter and

ther types of improper disposal along coastlines, rivers

and harbors.
