Sustainability is at the core of Polestar. The Swedish automaker is set on making vehicle development, production and ownership the cleanest process it can possibly be. A key part of that process is auditing partners and suppliers. “We all wish that we could trust everything that actors say in a value chain, but we know that that is not the case,” Head of Sustainability at Polestar, Fredrika Klarén, told Newsweek . Various parts of the supply chain are more susceptible to corruption than others.
