Sustainability Research Reveals Key Drivers of Consumer Adoption of Sustainable Banking Products

Strategic Insights -

A new study published in the International Review of Financial Analysis has investigated the reasons behind consumer adoption of sustainable bank accounts in Germany. The research, supported by ING DiBa Bank Germany, found that the most important determinant for adopting these accounts was sustainable finance self-efficacy, or the perceived impact that the consumer can make by using the product. Other significant drivers of adoption included the willingness to pay a premium for sustainability and trust in the bank provider. The study identified five distinct consumer clusters with different levels of adoption, highlighting the need for targeted industry and policy responses to accelerate the adoption of sustainable banking products.

Key Takeaways:
