Debate grows over whether some PFAS chemicals have a place in clean energy

By Shannon Kelleher

As the planet warms at an alarming rate, culminating in the hottest summer on record, nations worldwide are rapidly scaling up so-called clean energy technologies that can replace the world’s dependence on climate change-inducing fossil fuels.

More than 100 countries last year committed to triple renewable energy capacity by 2030 to try to slow climate change and reduce the related devastating human and environmental toll from increasingly frequent and extreme weather events.

In the United States, manufacturers of electric vehicles (EVs) and EV batteries have announced more than $188 billion in investments over the last nine years, with most of the money committed during the last two. And this May, the US Department of Energy (DOE) announced a $71 million investment in projects to expand access to solar power – dubbed the “cheapest form of energy” by the DOE.

But behind the enthusiasm lies a little-discussed but looming concern. Many of these technologies being heralded as tools to turn back climate change rely on fluoropolymers, a family of plastics that are part of a class of chemicals known as per- and polyfluoroalkyl substances (PFAS). Many types of PFAS are considered so hazardous that the US and many other countries have targeted them for elimination.

PFAS have been identified as ubiquitous environmental pollutants that don’t break down naturally, with several linked to a range of human health problems. Fluoropolymer safety for humans and the environment is still a matter of debate.

But the paradox of boosting the use of potentially harmful types of PFAS chemicals in order to create technologies that can address harmful climate change is stirring debate among some experts and prompting a deeper look at the pursuit of “clean energy”.

“Obviously, the green energy transition is very important,” said Ian Cousins, a professor at the University of Stockholm in Sweden who studies the environmental impact of PFAS. “I don’t want to hinder that. But at the same time… the green industry should be not just green energy but green in every regard.”

Interview: Lawyer Rob Bilott on PFAS “worldwide public health threat” and his letter to President Biden

Last month, an Ohio court certified a class action lawsuit brought by lawyer Rob Bilott that would cover seven million people – and at some point potentially everyone living in the United States – who have been exposed to certain hazardous chemicals known as Per- and Polyfluoroalkyl Substances or PFAS. The chemicals have been linked to cancer, birth defects, kidney disease and a range of other human health problems. They are dubbed “forever chemicals” because they do not naturally break down, persisting indefinitely in the environment. Two types of PFAS – PFOA and PFOS – have been found to be so harmful that they are being phased out of use. In addition to 3M, the class action lawsuit names ten other companies that produce PFAS, which are used to make cookware, food packaging, water-resistant fabrics, firefighting foam and other products. The Biden administration last year pledged to undertake a massive PFAS mitigation strategy at a cost of more than $10 billion.

You have spent 20 some years now focused on exposing the danger of a class of chemicals we call PFAS, using litigation to try to hold companies involved in spreading PFAS accountable, and pressuring regulators to step up and do more to protect the public. You’ve written a book, “Exposure,” been featured in the NY Times as “The Lawyer Who Became DuPont’s Worst Nightmare” and your legal battle has been made into a Hollywood movie called “Dark Waters,” as well as a documentary. Why are you so passionate about this issue?
