A highly recommended professional.”


Ruth Romer, Biodiversity and Water Project Manager

"IPIECA has worked with James on several projects and he has been consistently successful in meeting our desired outcomes. He has deep technical knowledge in the Biodiversity and Ecosystem Services (BES) arena. He also has a wealth of experience with oil and gas companies and understands the difficulties they face in determining BES dependencies, impacts and potential opportunities.”


Christopher Earl, Safety, Security, Health and Environmental Manager

"James and I have been working together on the Natural Capital Protocol for around two years. James was the technical consultant assisting with the deep dive pilot test that Roche undertook as part of the Protocol’s development. His extensive experience and knowledge in environmental economics in a business context was key to helping Roche complete a successful project in a time efficient manner. James is passionate about his work and is committed to delivering high quality results in a coherent format. He has the ability to break down complex issues thereby creating a clear overview. I, therefore, highly recommend James to any company seeking help with this topical subject."

James has a very pragmatic approach and understands the business environment very well. James is an excellent environmental economist and I would highly recommend him to any other company looking to apply Natural Capital measurement and valuation."
