Global leaders will gather in Canada’s capital this week to discuss progress in drafting a first-ever global treaty to rein in soaring plastic pollution by the end of the year.

The hoped-for treaty, due to be agreed at the end of this year, could be the most significant deal relating to climate-warming emissions and environmental protection since the 2015 Paris Agreement, which got 195 parties to agree to keep global temperatures from rising beyond 1.5 degrees Celcius.

At the U.N. Environment Assembly in 2022, nations agreed to develop a legally binding agreement by the end of 2024 to address the world’s plastic pollution crisis. The treaty is set to address plastics through their entire lifecycle – from when they are produced, to how they are used and disposed of. But negotiators have a tough task in Ottawa, Ontario, with countries divided over how ambitious the treaty should be.

What’s the problem with plastics?

While plastic waste has become a global menace polluting landscapes and waterways, producing plastics involves releasing greenhouse gas emissions. The plastic industry now accounts for 5% of global carbon emissions, which could grow to 20% by 2050 if current trends continue, said a report last week from the U.S. federal Lawrence Berkeley National Laboratory.

Plastic production is on track to triple by 2060 — unless the treaty sets production limits, as some have proposed. Most virgin plastic is derived from petroleum.

What is the challange in Ottawa?

This week’s talks are set to be the biggest yet, with some 3,500 people registered to attend including lobbyists, scientists and environmental non-profits. But countries have become divided on the issues during three previous rounds of talks held in Punta del Este, Uruguay, Paris, France and most recently in Nairobi, Kenya.

At the Nairobi talks in November, the draft treaty under review ballooned from 30 pages to 70 as some countries insisted on including their objections to more ambitious measures like production limits and phase-outs. Countries are now under pressure to find common ground before the final negotiations are held in December in Busan, South Korea.

What are different nations saying?

Many plastic and petrochemical-producing countries including Saudi Arabia, Iran and China — known collectively as the group of Like-Minded Countries — have opposed mentioning production limits. They blocked other countries from formally working on proposed treaty language calling for production caps, chemical disclosures or reduction schedules after last year’s Nairobi session.

Meanwhile, the 60-nation “High-Ambition Coalition”, which includes EU countries, island nations, Japan and the UAE, wants to end plastic pollution by 2040.

Backed by some environment groups, this coalition has called for common, legally binding provisions to “restrain and reduce the production and consumption of primary plastic polymers to sustainable levels.” They also are proposing measures such as phasing out “problematic” single-use plastics and banning certain chemical additives that could carry health risks.

The U.S. says it also wants to end plastic pollution by 2040. But unlike the High-Ambition Coalition, it wants countries to set their own plans for doing so, and to detail those plans in pledges sent regularly to the United Nations.

What do the petrochemical industry want?

The trade group Global Partners for Plastics Circularity represents major petrochemical producers, including members of the American Chemical Council and Plastics Europe.

The group argues that production caps would lead to higher prices and that the treaty should address plastics only after they are made. These companies want to focus on encouraging the reuse or recycling of plastics, and on developing the market for burning plastics as fuel, though a previous Reuters investigation found enormous obstacles in this method.

The group says companies should be allowed to disclose those chemicals used in production voluntarily.

What to corporates want?

More than 200 consumer-facing companies including Unilever, PepsiCo and Walmart have joined the so-called Business Coalition for a Plastics Treaty.

Like the petrochemical industry, these companies that rely on plastic packaging for their products have been a major presence in the plastics negotiations. However, they support a treaty that includes production caps, use “restrictions and phase-outs, reuse policies, product design requirements, extended producer responsibility, and waste management,” according to a statement ahead of the Ottawa talks.
