Plastic waste is piling up at a frightening tempo world wide. The World Financial institution estimates that each individual on the planet generates a median of 1.6 kilos (0.74 kilograms) of plastic waste day by day.
To curb this circulation, 175 nations are negotiating a binding worldwide treaty on plastic air pollution, with a completion goal of late 2024. In July 2024, the Biden administration launched the first U.S. plan for addressing this downside.

The brand new U.S. technique covers 5 areas: plastic manufacturing, product design, waste era, waste administration and plastic seize and removing. It additionally lists actions that federal businesses and departments are at present pursuing.
I examine environmental regulation, together with efforts to scale back plastic air pollution. Because the world’s largest economic system, the U.S. is a crucial participant on this effort. Primarily based on my analysis, listed below are three proposals within the U.S. plan that I imagine are essential and one omission that I view as a serious hole.
A federal commonplace for measuring microplastics
Research have detected tiny plastic fragments, often known as microplastics, in settings that embrace the environment, ingesting water sources, wild animals and human meals chains.
Whereas scientists have discovered that wildlife, similar to seabirds, might be harmed by consuming plastic, the results on human well being are much less clear. Not like different pollution, microplastics have completely different results relying on their measurement, their form and the place they’re discovered, similar to in meals, air or water. And people might be uncovered to them through many various pathways, together with inhalation, ingestion and contact.
There is no such thing as a federal commonplace for measuring microplastics in varied media, similar to water and soil, so research lack standardized definitions, strategies and reporting methods. In 2023, California launched a microplastic monitoring program, which incorporates growing a standardized technique for measuring microplastics in ingesting water.
The Biden administration’s plan requires growing standardized strategies for accumulating, quantifying and characterizing microplastics and nanoplastics, that are even smaller. This can assist scientists generate constant information that regulators can use to set limits on microplastics in meals, water and air.
Prolonged producer duty
All plastics include chemical substances that add properties similar to power, softness, shade and fireplace resistance. A subset of those chemical substances, together with bisphenols and phthalates, have been linked to antagonistic well being results that embrace fetal abnormalities, reproductive well being issues and most cancers.
Some scientists argue that sure varieties of plastic waste with notably dangerous substances or properties, together with PVC, polystyrene, polyurethane and polycarbonate, must be categorized as hazardous waste. At the moment, the U.S., Europe, Australia and Japan contemplate gadgets produced from these plastics as stable waste and deal with them in the identical method as kitchen meals scraps or used workplace paper.
The truth that solely about 5% of U.S. plastic waste is at present recycled, whereas 9% is incinerated and 86% is buried in landfills, has sparked requires assigning some duty to plastic producers.
Prolonged producer duty legal guidelines, which exist for different merchandise similar to paint and electronics, make producers accountable for accumulating and disposing of their merchandise or paying a part of the prices to handle these wastes. Such necessities give producers incentives to create extra environmentally pleasant merchandise and help recycling.
As of mid-2024, California, Colorado, Maine and Oregon have adopted prolonged producer duty legal guidelines for plastic waste, and a few dozen different states are contemplating related measures. Research present that when such insurance policies are adopted, recycling charges enhance.
The Biden administration plan requires launching a nationwide prolonged producer duty initiative that will enable state, native and tribal governments to develop their very own approaches whereas providing a imaginative and prescient for a harmonized nationwide system and targets for plastic waste administration. Assist on the federal degree might assist extra jurisdictions enact guidelines that require producers to assist handle these wastes.
Banning single-use plastics
Bans on plastic gadgets are a device to scale back waste era. Most of those measures apply to gadgets which might be used as soon as and discarded, similar to purchasing baggage, meals wrappers and plastic bottles. Objects like these are the most typical plastics within the atmosphere.
The U.S. plan requires growing methods to “substitute, scale back, and section out pointless use and buy of plastic merchandise by the Federal Authorities,” together with an finish to the acquisition of single-use plastic gadgets by 2035. Though this motion applies solely to make use of by federal businesses, the U.S. authorities is the largest single purchaser of products and companies on this planet, so this step can ship a strong sign in favor of different merchandise.
Capping plastic manufacturing
Present projections recommend that international plastic manufacturing will double by 2040, with an accompanying surge in plastic waste. In response, 66 nations have shaped the Excessive Ambition Coalition, co-chaired by Norway and Rwanda, to help stringent provisions within the international plastics treaty. Considered one of their central targets is limiting international plastic manufacturing.
Early in 2024, a number of nations taking part within the treaty negotiations proposed to chop world plastic manufacturing 40% beneath 2025 ranges by 2040. This idea remains to be beneath dialogue.
Plastic producers and firms reliant on plastic argue {that a} manufacturing cap would drive up the prices of all plastics. As an alternative, teams like the World Plastics Council are calling for steps that would cut back plastic waste era, similar to utilizing resins with extra recycled content material and growing recycling charges.
By way of mid-2024, the U.S. had not endorsed a cap on plastic manufacturing. Nevertheless, in August, press reviews acknowledged that the Biden administration was altering its place and will help limits, together with creating a world listing of goal chemical substances to limit.
It is a main change that I count on might transfer extra nations to help limits on new plastic manufacturing. Particulars are prone to emerge as the ultimate spherical of negotiations, scheduled for November 2024 in Busan, South Korea, approaches. The plastics trade strongly opposes limiting manufacturing, and Congress must ratify a world treaty to make its provisions binding on the U.S. However U.S. help might increase the probabilities of capping the ever-increasing circulation of plastic into the world economic system.
