This book focuses on the global trend of “carbon peak” and “carbon neutrality”. It comprehensively describes the theories and models for cities to move toward the goal of “dual-carbon”, analyzes the successful experiences of major countries and cities over the world, and proposes concrete paths and strategies to achieve “carbon peak” and “carbon neutrality” in close connection with the actual situation of Chinese cities. It’s not only a professional book with profound academic value, but also an interesting one for promotion of urban sustainable development with rich content. The basis of English translation of this book, originally in Chinese, was facilitated by artificial intelligence. The content was later revised by the author for accuracy.
