The Plastic Externality

Every tonne of plastic produced carries environmental and health costs that no producer has ever paid. The Plastic Cost Coverage Ratio compares what producers actually pay to the full external cost their production imposes on the environment and on human health — consistently between 0.01 and 0.05, meaning plastic producers capture less than five cents in environmental liability for every dollar of damage their products create.

The Plastic Externality, Part 4: Who Pays?

Audits the EU Plastics Strategy, Extended Producer Responsibility regimes, and the UN Global Plastics Treaty INC process against the Plastic Cost Coverage Ratio, demonstrating the gap between policy ambition and industrial accountability.

The Plastic Externality, Part 3: The Microscopic Crisis

Documents the discovery of microplastics in human blood (2020) and nanoplastics in human brain tissue (2023), and applies precautionary arithmetic to the incomplete and contested epidemiology of plastic particle health effects.
