This book investigates the relationship between environmental degradation and income, focusing on carbon dioxide (CO₂) emissions from around the world, to explore the possibility of sustainable development under global warming. Although many researchers have tackled this problem by estimating the Environmental Kuznets Curve (EKC), unlike the approach to sulfur dioxide emissions, there seems to be little consensus about whether EKC is formed with regard to CO₂ emissions. Thus, EKC is one of the most controversial issues in the field of environmental economics. This book...
