- 4.9–12.7 million metric tons of plastic enter the ocean every year (2015 estimates from Jambeck et al.)
- 32% of global plastic waste was mismanaged in 2016 (leaked or inadequately treated)
- 5–50 trillion plastic particles (median ~40 trillion) are estimated to be floating at the ocean surface
- Approximately 79,000 metric tons of plastic float on the surface of the Mediterranean Sea (estimated mass)
- Between 42% and 76% of microplastics found in beach sediments are fibers (composition)
- Fisheries capture plastic ingestion by marine organisms: 14% of marine species have been affected by marine debris in general (meta-analysis)
- 2% of all seabirds are estimated to be impacted by plastic ingestion (global assessment estimate)
- Up to 28% of some seabird species’ chicks may ingest plastic in certain regions (study findings)
- Global fishing and aquaculture revenues are estimated at $463 billion in 2018, with marine debris contributing to economic impacts (context for losses)
- $3.8 billion per year in the U.S. (marine debris impact estimate; 2020 assessment)
- $1.6 billion per year in costs in the UK associated with marine litter (estimate)
- 66% of respondents in a global plastics survey reported having a plastic reduction target (survey statistic)
- The EU Single-Use Plastics Directive includes a restriction on 10 product types, including plastic cutlery and straws (policy scope)
- The EU Packaging and Packaging Waste Regulation (PPWR) proposal sets targets for recyclable packaging: 100% of packaging on the EU market recyclable by 2030 (proposal text)
Every year about 8 to 13 million tons of plastic enter the ocean, largely from mismanaged waste.
