Toward a global treaty on plastic waste

Berlin—If there are any geologists in millions of years, they will easily be able to pinpoint the start of the so-called Anthropocene—the geological age during which humans became the dominant influence on our planet’s environment. Wherever they look, they will find clear evidence of its onset, in the form of plastic waste.

Plastic is a key material in the world economy, found in cars, mobile phones, toys, clothes, packaging, medical devices, and much more. Worldwide, 322 million metric tons of plastic were produced in 2015. And the figure keeps growing; by 2050, it could be four times higher.

But plastic is creating massive global environmental, economic, and social problems. Despite requiring resources to produce, plastic is so cheap that it often is used for disposable—often single-use—products. As a result, a huge amount of it ends up polluting the earth.

Plastic clogs cities’ sewer systems and increases the risk of flooding. Larger pieces can fill with rainwater, providing a breeding ground for disease-spreading mosquitos. Up to 13 million tons of plastic waste end up in the ocean each year; by 2050, there could be more plastic in there than fish. The plastic that washes up on shores costs the tourism industry hundreds of millions of dollars a year.

All that plastic poses a serious threat to wildlife. Beyond the dead or dying seals, penguins, and turtles that had the bad fortune of getting entangled in plastic rings or nets, biologists are finding dead whales and birds with stomachs stuffed with plastic debris.

Plastic products may not be all that good for humans, either. While the plastics used, say, to package our foods are usually nontoxic, most plastics are laden with chemicals, from softeners (which can act as endocrine disruptors) to flame retardants (which can be carcinogenic or toxic in higher concentrations). These chemicals can make it through the ocean and its food chain—and onto our plates.

Addressing the problem will not be easy; no single country or company, however determined, can do so on its own. Many actors—including the biggest plastic producers and polluters, zero-waste initiatives, research labs, and waste-picker cooperatives—will have to tackle the problem head-on.

The first step is to create a high-level forum to facilitate discussion among such stakeholders, with the goal of developing a cooperative strategy for reducing plastic pollution. Such a strategy should go beyond voluntary action plans and partnerships to focus on developing a legally binding international agreement, underpinned by a commitment from all governments to eliminate plastic pollution. Negotiations on such a treaty could be launched this year, at the United Nations Environment Assembly in Nairobi in December.

Some might ask whether we should embark on yet another journey down the long, winding, and tiresome road of global treaty negotiations. Can’t we engineer our way out of our plastic problem? The short answer is, probably not. The only way truly to address the problem is to slash our plastic waste. Technology might be able to help, offering more options for substitution and recycling; but, as the many zero-waste communities and cities worldwide have shown, it is not necessary.

For example, Capannori, a town of 46,700 inhabitants near Lucca in Tuscany, signed a zero-waste strategy in 2007. A decade later, it has reduced its waste by 40 percent. With 82 percent of municipal waste now separated at source, just 18 percent of residual waste ends up in landfills. Such experiences should inform and guide the national action plans that would form part of the treaty on plastics.

Of course, the transition to zero waste will require some investment. Any international treaty on plastic must include a funding mechanism, and the “polluter pays” principle is the right place to start. The global plastic industry, with annual revenues of about $750 billion, surely could find the money to help clean up the mess it created.
