Jan-Kees Vis, a staff worker in the middle echelons of the company, attempts to integrate sustainable development into existing environmental policy in hopes of providing a plan of action for achieving sustainability. Once the new policy is adopted, the case leaves the student to decide how the company should begin fulfilling its commitments. The D case concludes the story of Vis's attempts to integrate sustainable development into Unilever's existing environmental policy in hopes of providing a plan of action for achieving sustainability, and describes the company's efforts to fulfill its commitments.
