This book analyzes the interplay between development and the environment, focusing on how to forge social consensus and practices in the international community. Since the Rio Earth Summit in 1992, sustainable development has increasingly attracted the attention of the international community, and several international agreements have been concluded to combat issues such as climate change. The Sustainable Development Goals (SDGs) were introduced as common objectives, and the Paris Agreement was adopted as a subsequent outcome. In light of today’s globalized world, how to best achieve sustainable development—and prioritize climate change in particular—is an issue involving various perspectives on the environment and economic development in the global community.
