Measurement method for plastic impact on investments

We have developed a methodology to provide insight into the plastic footprint of investment portfolios. The method is a co-creation of a.s.r., Earth Action, and the Plastic Soup Foundation, making a.s.r., as far as is currently known, the first company within the financial sector to apply this method.

Indication of plastic impact

The approach makes it possible to provide an indication of the plastic impact of companies and portfolios, including potential effects on the environment and health, based on available data and assumptions. Over the past few months, a.s.r. was the first financial institution to test the method in a pilot, in which plastic pollution and associated health risks were mapped, among other things. The pilot provided insight into which companies in the investment portfolio may have a major negative impact on plastic pollution.

Making the blind spot visible

Marjolein Meulensteen, Portfolio Manager Responsible Investing at a.s.r. Asset management: “With this methodology, we are making a blind spot in the financial sector visible; the impact of plastic pollution on the environment and health often remains underexposed. Investors gain more insight into potential plastic impact and associated risks, which can support them in their investment decisions.”

Transparent, reproducible, and immediately usable

The methodology translates existing insights regarding ‘financed emissions’ into plastic pollution. Because data is still limited, the model combines company- and sector-specific data to estimate potential impact. “To translate the logic of financed emissions into plastic pollution, it was necessary to develop entirely new data layers. The result is a methodology that is transparent, reproducible, and immediately usable, including for other financial institutions, with the aim of offering an approach that is as transparent and reproducible as possible,” says Riccardo De Gennaro, PhD, data specialist at Earth Action and developer of the methodology.

Plastic pollution: financial and systemic risk

For the collaborating parties, plastic pollution is no longer just an environmental problem; it is a financial and systemic risk. Methodologies such as this can contribute to further transparency and decision-making regarding plastic impact in portfolios. According to the Plastic Soup Foundation, the development of this method is urgently needed. “Plastic pollution is also a health issue. It is essential that financial institutions translate this into concrete action,” says Maria Westerbos, founder and director of the Plastic Soup Foundation.
