Our new model approach includes geographically distributed data on plastic waste, land use, wind, precipitation, and rivers. The updated model then calculates the probability for plastic waste to reach a river and subsequently the ocean.
This probabilistic approach highlights regions that are likely to emit plastic into the ocean. Combined with mismanaged plastic waste, displayed in this map, our model predicts plastic emissions for each river. Detailed information on our modeling approach and data will follow in our scientific update.
