  2. 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. 1. That means 0.5% of plastic waste ends up in the ocean.

  3. Oct 5, 2023 · Plastic waste inputs from land into the ocean. Science, 347 (6223), 768-771. The OECD Global Plastics Outlook estimates that 1.7 million tonnes ends up in the oceans. A recent study by Meijier et al. (2021) estimates that this figure is around 1 million tonnes.

    • To Tackle Plastic Pollution We Need to Know Where It’S Coming from

    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. What rich countries cando is support low-to-middle income countries in improving waste management infrastruct...

  4. More than 171 trillion pieces of plastic are now estimated to be floating in the world's oceans, according to scientists. Plastic kills fish and sea animals and takes hundreds of years to break...

  5. Oct 21, 2021 · Currently, plastic accounts for 85 per cent of all marine litter. By 2040, it will nearly triple, adding 23-37 million metric tons of waste into the ocean per year. This means about 50kg of...

  6. Feb 12, 2015 · The scientists figured roughly 15% to 40% of that littered or dumped plastic enters the ocean each year. Adding together all 192 countries in the world with a significant coastal population, the researchers report online today in Science that about 4 million to 12 million metric tons of plastic washed offshore in 2010 alone, or about 1.5% to 4. ...

  7. The numbers are staggering: There are 5.25 trillion pieces of plastic debris in the ocean. Of that mass, 269,000 tons float on the surface, while some four billion plastic microfibers per square kilometer litter the deep sea.
