Scientists Call for Cap on Production to End Plastic Pollution

Now, after the United Nations’ historic decision to adopt a global treaty to end plastic pollution earlier this year, governmental negotiations on the agreement are set to begin on May 30. These will foster intense debates on what types of measures will be needed to end the pollution of the air, soil, rivers, and oceans with plastic debris and microplastics.

In a letter to the journal Science, an international group of scientists and experts now argue for tackling the issue of plastic pollution right at the source by regulating, capping, and in the long term phasing out the production of new plastics.

Recycling is not enough to end plastic pollution

Melanie Bergmann of the German Alfred Wegener Institute, the initiator of the letter, said:

“Even if we recycled better and tried to manage the waste as much as we can, we would still release more than 17 million tons of plastic per year into nature. If production just keeps growing and growing, we will be faced with a truly Sisyphean task.”

Along with measures to address the consumption and demand side of the problem — such as taxes — a comprehensive approach must also cover the supply side, meaning the actual amount of plastics produced and put on the market. (Image: via Pixabay)

Research published in Science in 2020 shows that plastic emissions can only be cut by 79 percent over the next 20 years if all solutions available today are implemented, including replacing some plastics with other materials, and improved recycling and waste management. Bethanie Carney Almroth of the University of Gothenburg, Sweden, said:

“The exponentially growing production is really the root cause of the problem, and the amounts of plastics we have produced thus far have already exceeded planetary boundaries. If we don’t tackle that, all other measures will fail to achieve the goal of substantially reducing the release of plastic into the environment.”

Phasing out new plastics important

Phasing out the production of new plastics from fresh feedstocks should be part of a systemic solution to end plastic pollution, the experts from Canada, Germany, India, Norway, Sweden, Turkey, the UK, and the U.S. argue.

This approach is supported by the best science available today and in line with what political and legal experts proposed in Science last year. Along with measures to address the consumption and demand side of the problem — such as taxes — a comprehensive approach must also cover the supply side, meaning the actual amount of plastics produced and put on the market.

Reducing production increases the value

Gradually cutting the production of new plastics will come with many societal, environmental, and economic benefits, the scientists say. Sedat Gündoğdu of Cukurova University, Turkey, says:

“The massive production also feeds the plastic waste transfer from the Global North to the South. A production cap will facilitate getting rid of non-essential applications and reduce plastic waste exports.”

Martin Wagner, an ecotoxicologist at the Norwegian University of Science and Technology, added:

“We gain a lot of benefits from plastics but reducing production will increase the value of plastics, boost other measures to curb plastic pollution, help tackle climate change and promote our transition to a circular and sustainable economy.”
