   How many rivers make up 80% of global plastic emissions?

   • Our study - published today in Science Advances – estimates that 1000 rivers account for nearly 80% of global riverine plastic emissions into the ocean, made up of a high number of small and medium-sized rivers.

   How much plastic does a river emit?

   • Two previous studies (2017) gathered data on mismanaged plastic waste generated within a river basin and applied a correction factor to estimate the river’s plastic emission. These studies predicted that as little as 5 or 47 rivers account for 80% of riverine plastic emissions.

   How much plastic flows into the oceans through rivers?

   • The publication sheds new light on where and how much plastic flows into the oceans via rivers. With the help of new measurements and modeling, the study shows that 1000 rivers shed almost 80% of plastic emissions. This number is 100 times more than the 10 rivers that were previously thought to be responsible for most of the pollution.

   How much do Asian rivers contribute to global plastic emissions?

   • According to these studies, the 10 largest emitting rivers contribute 50 to 61% and 88 to 94% to the total river emissions. Both models agreed on a disproportional contribution of Asian rivers to global plastic emissions.

   Do rivers contribute to the influx of plastic to the ocean?

   • Our model suggests that instead of a handful of large continental rivers contributing the most emissions, a high number of small and medium-sized rivers play a significant role in the influx of plastic from rivers to the ocean.

   Global distribution of riverine plastic emissions. Of the total 100,887 outlets of rivers and streams included in our model, we found that 31,904 locations emit plastic waste into the ocean, leaking in 1.0 (0.8 to 2.7) million MT into the marine environment in 2015.
