   Oct 5, 2023 · Around 0.5% of the world’s plastic waste enters the oceans each year, mostly from rivers and coastlines. Most of it stays close to the shoreline, while some sinks to the seabed and less than 0.1% floats on the surface.

   To tackle plastic pollution we need to know what rivers these plastics are coming from. It also helps if we understand whythese rivers emit so much. Most of the world’s largest emitting rivers are in Asia, with some also in East Africa and the Caribbean. In the chart we see the ten largest contributors. This is shown as each river’s share of the gl...

   Asia accounts for 81% of global plastic inputs to the ocean

   We’ve looked at the role of individual rivers, but how do these aggregate at the regional and country-level? Which countries emit the most plastic to the ocean? In the chart we see the breakdown of global plastic inputs to the ocean by region. 81% of ocean plastics are emitted from Asia. The fact that a disproportionate amount of plastic pollution comes from Asia is consistent with previous research. Earlier studies estimated its share in 2010 was 86%.5 This should also not surprise us given...

   More than one-third of ocean plastic inputs come from the Philippines

   The distribution of plastic inputs is reflected on the world map. There we see each country’s share of global plastic emissions. The Philippines accounts for more than one-third (36%) of plastic inputs – unsurprising given the fact that it’s home to seven of the top ten rivers. This is because the Philippines consists of many small islands where the majority of the population lives near the coast. But it’s an important update on our previous understanding of where China and India were thought...

   We can understand what determines each country’s contribution through three steps. First, the amount of plastic waste that each country generates in the first place. Rich countries produce much more plastic waste per person than poorer countries. Most produce 0.2 to 0.5 kilograms per person per day.8 This compares to 0.01 in India or 0.07 kilograms...

   Identifying where plastic emissions are coming from really matters for how we tackle it. Rich countries emit very little – this means domestic strategies to reduce plastics in these countries will not make much difference to ocean plastics.

   How much plastic enters the ocean? Plastic leaks into the ocean from thousands of sources all over the world every day. Increasing consumption combined with improper waste management in many countries has made plastic pollution a worldwide problem, causing damage not only to the environment but also to human health and economies.

   How much plastic is in the ocean?

   • Help NOAA understand and prevent marine debris by recording what you pick up with the Marine Debris Tracker. While it’s tough to say exactly how much plastic is in the ocean, scientists think about 8 million metric tons of plastic entered the ocean in 2010. That’s the weight of nearly 90 aircraft carriers, and the problem continues to grow.

   How long does plastic stay in the ocean?

   • It can take years for a plastic piece to break free from these coastal waters and be carried out to the open ocean – but once it’s out there, it can stay there for a long time. Plastic accumulates in huge subtropical oceanic areas called gyres – massive circular currents that trap the floating plastic for decades, if not centuries.

   How much plastic waste goes to the ocean?

   • 1.7 million tonnes of this is then transported to the ocean: 1.4 million tonnes from rivers, and 0.3 million tonnes from coastlines. The rest of the plastic waste that was leaked into aquatic environments accumulated in rivers and lakes. That means that around 0.5% of world’s plastic waste ends up in the oceans.

   How much plastic does the world produce a year?

   • Even just in the last two decades, global plastic production has doubled. The world produces around 350 million tonnes of plastic waste each year. Estimates vary, but recent high-quality studies suggest that between 1 and 2 million tonnes of plastic enter the oceans annually. That means 0.5% of plastic waste ends up in the ocean.

   How much plastic pollution is in the ocean?

   • Less than 0.5 percent . This is because only a small proportion of plastic is disposed of incorrectly, and an even smaller part of that enters waterways. This does not mean the ocean plastic pollution problem is “small” – over 1 million metric tons is still a massive amount of pollution.

   Where does most plastic go in the ocean?

   • As is shown in the chart, most plastic flowing into the ocean today comes from middle-income countries – particularly across Asia. While we might think that much of the world’s plastic waste is recycled, only 9% is. Half of the world’s plastic still goes straight to landfill.

   From the tiniest plankton to the largest whales, plastics impact nearly 700 species in our ocean. You’ve probably seen videos of these impacts first hand, like a sea turtle with a plastic straw embedded in its nose or a whale entangled in a fishing net, approaching divers that release it from harm.
