2 of the 50 named highest-emission river outfalls in the Meijer et al. (2021) global model are in Cameroon. Together these named rivers carry a modeled 5,173 metric tons of plastic to the ocean per year, 0.5% of the modeled global total across 31,819 outfall points.

named rivers from Cameroon among the dataset's top 50 outfalls
Country attribution in this dataset exists only for the 50 named outfalls from the study's human-reviewed table (Table S5). The figures on this page cover those named rivers only. They are not a national total: the study models thousands of additional outfall points whose country attribution has not been verified on this site.
Named rivers in Cameroon, ranked by modeled emission
Each profile below explains local context, the modeled emission rank, drivers, and caveats for interpreting the data. Values are modeled annual plastic mass reaching the ocean, from Meijer et al. (2021).
Rank #43 of 31,819 modeled outfall points. Modeled emission 2,338 metric tons per year, Atlantic Ocean basin.
Cameroon River Plastic FAQ
Which river in Cameroon carries the most plastic to the ocean?
In the Meijer et al. (2021) model, the Wouri River is the highest-ranked named outfall in Cameroon, at rank #26 of 31,819 modeled points with 2,835 metric tons per year. The value is a modeled estimate, not a direct measurement.
How many rivers in Cameroon are among the world's highest-emitting?
Cameroon has 2 rivers among the 50 named highest-emission outfalls in the dataset. The study models many more outfall points whose country attribution has not been verified on this site, so this is a floor, not a national total.
What share of global river plastic emissions comes from Cameroon?
The named rivers from Cameroon in this dataset together represent 0.5% of the modeled global total across all 31,819 outfall points. Because only the top 50 outfalls carry verified country attribution, the country's full share is higher than this named-rivers figure.
