Boston, May 5th, 2023 – One hundred and eighty five investors with $10 trillion in assets under management, including Green Century°, have signed a statement demanding that companies adopt a more radical approach to reducing their reliance on plastics. Specifically, investors urge intensive users of plastic packaging – such as consumer goods companies and grocery retailers from Kellogg* to Costco* – to drastically reduce single-use plastic packaging, implement packaging reuse systems, phase out hazardous chemicals in plastics, and advocate for policies supporting these actions.


“The plastics life cycle not only poses a grave and growing threat to our environment, but the financial burden on society from plastic pollution exceeds $100 billion per year,” said Leslie Samuelrich, President of Green Century Funds. “No convenience is worth those costs.”


Companies Need to Step Up to Solve the Plastics Problem


The damage caused to the environment from plastics is clear. Between 75 and 199 million tonnes of plastics have leaked into the ocean, and the total greenhouse gas emissions from single-use plastics in 2021 were equivalent to the annual emissions of the United Kingdom. Yet, according to the Ellen MacArthur Foundation, most companies will ‘almost certainly’ miss their existing plastics reduction targets, increasing their use of single-use plastic packaging overall and failing to demonstrate credible and ambitious plans for reuse.


“Investors are sending a clear signal that companies must urgently address their contribution to the plastic problem,” said Annie Sanders, Director of Shareholder Advocacy at Green Century Capital Management. “With increased regulation, litigation, and changing consumer preferences around plastics, it’s in companies’ best interests to meaningfully address the very real financial risks posed by this crisis.”


The investor letter asks companies to significantly reduce material consumption, eliminate single-use packaging and scale up reusable packaging systems, among other actions. The letter also calls for companies to publicly support – rather than lobby against – ambitious policy on plastic reduction, including the Global Plastics Treaty and the EU’s Packaging and Packaging Waste Regulation (PPWR). A recent analysis showed that lobbying efforts by industry associations already managed to considerably weaken some of the measures.


A sustainable investment strategy which incorporates environmental, social and governance criteria may result in lower or higher returns than an investment strategy that does not include such criteria.
