Global Trade Update (August 2025): Mobilising trade to curb plastic pollution

Plastics have fueled global growth across various industries, but at an increasing environmental, economic, and social cost.

Today, plastic pollution represents a systemic and transboundary crisis, disproportionately affecting developing countries that have limited capacity for waste management.

$1.1 trillion in plastic trade, but 75% ends up as waste

In 2023, global plastic production reached 436 million metric tons, while trade in plastics surpassed $1.1 trillion, accounting for 5% of global merchandise trade. However, 75% of all plastic ever produced has become waste, much of which leaks into oceans and ecosystems.

This growing imbalance threatens public health, food systems, ecosystems, and long-term development, especially in small island and coastal nations.

Global plastics trade in volume increased by 48 per cent between 2005 and 2023

Tariffs make plastics cheap but penalize natural substitutes

The average Most Favored Nation (MFN) tariffs on plastic and rubber products have decreased from 34% to 7.2% over the past three decades, making fossil fuel-based plastics artificially inexpensive.

In contrast, natural alternatives such as paper, bamboo, natural fibers, and seaweed face average MFN tariffs of 14.4%.

These disparities in how materials are treated discourage investment in alternative products and hinder innovation in developing countries that aim to export safer and more sustainable alternatives to fossil fuel-based plastics.

Plastic and rubber tariffs have declined almost 5-fold over the last three decades

Plastic pollution outpaces global policy response

Although plastics are directly linked to the triple planetary crisis—pollution, biodiversity loss, and climate change—there is still no comprehensive international treaty governing their composition, design, production, trade, and disposal.

With 98% of plastics derived from fossil fuels, emissions and environmental damage are expected to rise without coordinated multilateral action. Efforts to address these issues have been fragmented and incremental since the late 1980s.

Ongoing negotiations for a legally binding international instrument against plastic pollution hold promise for a comprehensive global response that encompasses the entire lifecycle of plastics.

Evolving international responses to the problem of plastic pollution

Countries are acting, but regulations are uneven and burdensome

Many countries are employing non-tariff measures (NTMs) to restrict the flow of harmful plastics through bans, labeling requirements, and product standards. However, the lack of alignment among these regulations increases compliance costs and slows trade in safer and more sustainable goods.

Small businesses and low-income exporters often struggle to navigate overlapping or inconsistent requirements, which limit their ability to engage in sustainable trade.

Technical regulations, bans and import licenses are the most common types of NTM applied to plastics

The $485 billion market for substitutes is growing but under-supported

In 2023, global trade in non-plastic substitutes reached $485 billion, with developing countries experiencing annual growth of 5.6%.

These substitutes, derived from mineral, plant, and animal sources, are biodegradable, compostable, or recyclable materials such as glass, seaweed, and natural fibers. However, high tariffs, limited market access, and weak regulatory incentives hinder the scale-up of these sustainable alternatives.

Global exports in non-plastic substitudes show an upward trend with some cyclical declines

Time for a treaty that aligns trade and sustainability

The upcoming Global Plastics Treaty presents a critical opportunity to integrate trade, finance, and digital systems into a cohesive global response. Without aligning trade practices, plastic flows and pollution will continue to rise.

A successful treaty should include:

  • Tariff and NTM reforms to support sustainable substitutes
  • Investment in waste management and circular infrastructure
  • Digital tools for traceability and customs compliance
  • Policy coherence across the WTO, UNFCCC, Basel Convention, and regional frameworks.

Trade must be part of the solution, not part of the problem.
