Since joining DNV in 2010 Jan-Henrik Hübner is supporting maritime clients in Europe, Middle East and Asia in a wide range of strategic and operational challenges. Jan-Henrik specializes on advice related to decarbonization and finance.

“I work with banks and investors that offer finance to ship owners and provide advice on the Poseidon Principles and sustainable finance, both cornerstones of the maritime ESG agenda that that have grown in importance the past 2-3 years. There is significant evidence that ESG-compliant lending lowers the risk of default to lenders, and that is the appeal to financiers.”
