Over the course of the book, academics and practitioners from various fields demonstrate why transitioning into a 'green economy' - a future economy based on environmental sustainability, social equity and improved well-being - is not an option but a necessity for the Gulf Cooperation Council (GCC) States. Through chapters covering key economic sectors and cross-cutting issues, the book examines the GCC states' quest to align their economies and economic development with the imperatives of environmental sustainability and social welfare, and proposes a way forward, based on lessons learned from experiences in the region and beyond.
