This book examines the current and controversial topic of the sulphur cap in maritime supply chains, a new regulation set to be enforced in 2020. The author presents extensive research on three northern countries - Finland, Sweden and Estonia - and the effects they felt when these regulations were rolled out in 2015. These regional case studies are presented alongside extensive private sector data, annual reports and interviews to assess and forecast how the maritime supply chain will cope with rising costs and alternative approaches to environmental regulations. This book includes advanced regression analyses alongside interactive simulation models for the reader to evaluate new supply chain strategies and study the effects of these regulations.
