Plastic waste is piling up at a frightening tempo all over the world. The World Financial institution estimates that each individual on the planet generates a median of 1.6 kilos (0.74 kilograms) of plastic waste every 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 drawback.

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 companies and departments are at the moment pursuing.
I examine environmental legislation, together with efforts to scale back plastic air pollution. Because the world’s largest financial 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 consider are essential and one omission that I view as a serious hole.
A federal customary for measuring microplastics
Research have detected tiny plastic fragments, generally known as microplastics, in settings that embody the environment, consuming water sources, wild animals and human meals chains.
Whereas scientists have discovered that wildlife, resembling seabirds, might be harmed by consuming plastic, the results on human well being are much less clear. In contrast to different pollution, microplastics have completely different results relying on their dimension, their form and the place they’re discovered, resembling in meals, air or water. And people might be uncovered to them by way of many various pathways, together with inhalation, ingestion and contact.
There isn’t any federal customary for measuring microplastics in numerous media, resembling water and soil, so research lack standardized definitions, strategies and reporting strategies. In 2023, California launched a microplastic monitoring program, which incorporates creating a standardized technique for measuring microplastics in consuming water.
The Biden administration’s plan requires creating standardized strategies for gathering, quantifying and characterizing microplastics and nanoplastics, that are even smaller. It will assist scientists generate constant information that regulators can use to set limits on microplastics in meals, water and air.
Prolonged producer accountability
All plastics include chemical compounds that add properties resembling power, softness, shade and hearth resistance. A subset of those chemical compounds, together with bisphenols and phthalates, have been linked to opposed well being results that embody fetal abnormalities, reproductive well being issues and most cancers.
Some scientists argue that sure sorts of plastic waste with significantly dangerous substances or properties, together with PVC, polystyrene, polyurethane and polycarbonate, needs to be categorised as hazardous waste. At the moment, the U.S., Europe, Australia and Japan think about gadgets constructed from these plastics as stable waste and deal with them in the identical manner as kitchen meals scraps or used workplace paper.
The truth that solely about 5% of U.S. plastic waste is at the moment recycled, whereas 9% is incinerated and 86% is buried in landfills, has sparked requires assigning some accountability to plastic producers.
Prolonged producer accountability legal guidelines, which exist for different merchandise resembling paint and electronics, make producers liable for gathering 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 assist recycling.
As of mid-2024, California, Colorado, Maine and Oregon have adopted prolonged producer accountability legal guidelines for plastic waste, and a couple of dozen different states are contemplating comparable measures. Research present that when such insurance policies are adopted, recycling charges enhance.
The Biden administration plan requires launching a nationwide prolonged producer accountability initiative that might 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. Help on the federal degree may 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 can be used as soon as and discarded, resembling buying luggage, meals wrappers and plastic bottles. Objects like these are the most typical plastics within the atmosphere.
The U.S. plan requires creating methods to “replace, reduce, and phase out unnecessary use and purchase of plastic products by the Federal Government,” 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 companies, the U.S. authorities is the largest single purchaser of products and providers on the earth, so this step can ship a robust sign in favor of other merchandise.
Capping plastic manufacturing
Present projections recommend that world plastic manufacturing will double by 2040, with an accompanying surge in plastic waste. In response, 66 nations have fashioned the Excessive Ambition Coalition, co-chaired by Norway and Rwanda, to assist stringent provisions within the world plastics treaty. One in all their central targets is limiting world 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 continues to be beneath dialogue.
Plastic producers and corporations 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, resembling utilizing resins with extra recycled content material and growing recycling charges.
By means of mid-2024, the U.S. had not endorsed a cap on plastic manufacturing. Nevertheless, in August, press experiences acknowledged that the Biden administration was altering its place and will assist limits, together with creating a world checklist of goal chemical compounds to limit.
This can be a main change that I anticipate may transfer extra nations to assist 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. assist may increase the possibilities of capping the ever-increasing circulation of plastic into the world financial system.
