These 20 Countries Are Sending Most of Their Garbage Into the Ocean

In a recent paper, researchers found that just three countries account for more than 50% of all plastic waste that ends up in the ocean. Different countries have different pollution mitigation strategies, and the degree of plastic emissions varies considerably.

While less than 1% of plastic waste generated in the United States ends up in the ocean, in some countries more than 10% of plastic waste reaches the world’s oceans. A closer look at the data reveals which countries are the worst offenders.
To determine the countries sending the most of their garbage into the ocean, Climate Crisis 247 reviewed data on plastic waste emissions from the April 2021 paper “More than 1000 rivers account for 80% of global riverine plastic emissions into the ocean.” Countries were ranked based on the percentage of mismanaged plastic waste – plastic waste that is improperly disposed of and at risk of entering natural environments – that enters rivers or other waterways and ultimately enters the ocean.
