The world is pumping out 57 million tons of plastic pollution a year

The world creates 57 million tons of plastic pollution every year and spreads it from the deepest oceans to the highest mountaintop to the inside of people’s bodies, according to a new study that also said more than two-thirds of it comes from the Global South.

It’s enough pollution each year — about 52 million metric tons — to fill New York City’s Central Park with plastic waste as high as the Empire State Building, according to researchers at the University of Leeds in the United Kingdom. They examined waste produced on the local level at more than 50,000 cities and towns across the world for a study in Wednesday’s journal Nature.

The study examined plastic that goes into the open environment, not plastic that goes into landfills or is properly burned. For 15% of the world’s population, government fails to collect and dispose of waste, the study’s authors said — a big reason Southeast Asia and Sub-Saharan Africa produce the most plastic waste. That includes 255 million people in India, the study said.

Lagos, Nigeria, emitted the most plastic pollution of any city, according to study author Costas Velis, a Leeds environmental engineering professor. The other biggest plastic polluting cities are New Delhi; Luanda, Angola; Karachi, Pakistan and Al Qahirah, Egypt.

India leads the world in generating plastic pollution, producing 10.2 million tons a year (9.3 million metric tons), far more than double the next big-polluting nations, Nigeria and Indonesia. China, often villainized for pollution, ranks fourth but is making tremendous strides in reducing waste, Velis said. Other top plastic polluters are Pakistan, Bangladesh, Russia and Brazil. Those eight nations are responsible for more than half of the globe’s plastic pollution, according to the study’s data.

The United States ranks 90th in plastic pollution with more than 52,500 tons (47,600 metric tons) and the United Kingdom ranks 135th with nearly 5,100 tons (4,600 metric tons), according to the study.

In 2022, most of the world’s nations agreed to make the first legally binding treaty on plastics pollution, including in the oceans. Final treaty negotiations take place in South Korea in November.

The study used artificial intelligence to concentrate on plastics that were improperly burned — about 57% of the pollution — or just dumped. In both cases incredibly tiny microplastics, or nanoplastics, are what turn the problem from a visual annoyance at beaches and a marine life problem to a human health threat, Velis said.

Several studies this year have looked at how prevalent microplastics are in our drinking water and in people’s tissue, such as hearts, brains and testicles, with doctors and scientists still not quite sure what it means in terms of human health threats.

“The big time bomb of microplastics are these microplastics released in the Global South mainly,” Velis said. “We already have a huge dispersal problem. They are in the most remote places … the peaks of Everest, in the Mariana Trench in the ocean, in what we breathe and what we eat and what we drink.”

He called it “everybody’s problem” and one that will haunt future generations.

“We shouldn’t put the blame, any blame, on the Global South,” Velis said. “And we shouldn’t praise ourselves about what we do in the Global North in any way.”

It’s just a lack of resources and ability of government to provide the necessary services to citizens, Velis said.

Outside experts worried that the study’s focus on pollution, rather than overall production, lets the plastics industry off the hook. Making plastics emits large amounts of greenhouse gas that contribute to climate change.

“These guys have defined plastic pollution in a much narrower way, as really just macroplastics that are emitted into the environment after the consumer, and it risks us losing our focus on the upstream and saying, hey now all we need to do is manage the waste better,” said Neil Tangri, senior director of science and policy at GAIA, a global network of advocacy organizations working on zero waste and environmental justice initiatives. “It’s necessary but it’s not the whole story.”
