Global producer responsibility for plastic pollution

Area of Science:

• Environmental Science
• Corporate Social Responsibility
• Pollution Studies

Background:

• Plastic pollution is a significant global environmental issue.
• Brand identification on plastic waste can facilitate corporate accountability.
• Previous research has focused on waste composition but less on brand-specific contributions.

Purpose of the Study:

• To identify major corporate brands contributing to global plastic pollution.
• To investigate the relationship between plastic production and branded pollution.
• To advocate for policies that hold producers accountable for plastic waste.

Main Methods:

• Utilized data from a 5-year global program (2018-2022) across 84 countries.
• Conducted 1576 audit events to identify brands on plastic items in the environment.
• Employed statistical analysis to determine the relationship between production and pollution.

Main Results:

• 50% of plastic items found in the environment were unbranded, necessitating mandated producer reporting.
• The Coca-Cola Company (11%), PepsiCo (5%), Nestlé (3%), and Danone (3%) were identified as top global plastic polluters.
• A strong log-log linear relationship exists between companies' plastic production and their branded plastic pollution.

Conclusions:

• Brand audits are effective in identifying major corporate contributors to plastic pollution.
• Food and beverage companies are disproportionately large plastic polluters.
• Phasing out single-use plastics from major polluters can significantly reduce global plastic waste.
