A report from the UN Environment Programme (UNEP) has shown that global plastic pollution could be slashed by 80% by 2040.
According to the agency which said that the changes needed are major, but are also practical and affordable, the first step is to eliminate unnecessary plastics, such as excessive packaging, the report said. Then next steps are to increase the reuse of plastics, such as refillable bottles, boosting recycling and replace plastics with greener alternatives.
Such a shift, driven by government policies and changes in the plastic industry, would mean plastic pollution would drop to about 40m tons in 2040, rather than 227m tons if no action is taken, the agency said in its report.
The changes are expected to bring benefits worth trillions of dollars between now and 2040 by reducing the damage caused by plastics to health, the climate and the environment.
Plastic now contaminates the entire planet, from the summit of Mount Everest to the deepest oceans. People consume microplastics via food and water, as well as breathing them in, and the particles have been found in people’s blood and breast milk.

Recall that in March 2022, 193 countries agreed to end plastic pollution, with negotiations on a legally binding agreement by 2024 now under way, hosted by UNEP. The second round of negotiations starts on 29 May. The world currently produces 430m tons of plastics a year, two-thirds of which are short-lived products that soon become waste. Production is set to triple by 2060 on current trends.
“The way we produce, use and dispose of plastics is polluting ecosystems, creating risks for human health and destabilising the climate,” said Inger Andersen, UNEP’s executive director. “This report lays out a roadmap to dramatically reduce these risks through adopting a circular approach that keeps plastics out of ecosystems, out of our bodies and in the economy.
“The report crucially demonstrates that the transformation would provide economic and social wins. Governments and the private sector would save money and hundreds of thousands of new jobs would be created,” she said.
The report also estimated that the increased reuse of plastics could reduce 30% of plastic pollution by 2040, with measures including deposit-return schemes for containers. Such a scheme is due to start in England in 2025, seven years after it was first announced.
Findings presented in the report also showed that more recycling would cut pollution in 2040 by a further 20%, the report said. Taxing virgin plastic and removing fossil fuel subsidies are policies that would encourage this, by making recycling more economically attractive compared with producing new plastic. Enforcing packaging guidelines to increase the recyclability of products would also be important.
It said that the careful replacement of plastic products, such as takeaway food containers, with alternative materials such as paper or compostable materials could cut another 17% from pollution in 2040.
“Plastic items from takeaway food and drink dominate the litter in the world’s oceans, according to a 2021 study. There would still be a lot of plastic waste to be disposed of safely in 2040, and making manufacturers responsible for this would help,” the UNEP report said.
