Written by leading experts and industry voices, the book reveals the environmental, social, cultural and regulatory challenges shaping the future of cruising, and the creative solutions to address them.

Engaging, insightful, and practical, this book bridges the gap between research and real-world action. Through case studies, key takeaways, and inspiring examples, it shows how the cruise industry can chart a more responsible course that honours both people and planet.
