This book offers a comprehensive and structured exploration of how financial systems are being reshaped to support the net-zero transition. It guides readers through the evolving architecture of standards, instruments, and market mechanisms that underpin climate-aligned capital flows. Using an accessible but conceptually rigorous approach, it distinguishes climate finance from green and sustainable finance and examines key tools such as corporate and sovereign green bonds, blue finance, and carbon markets. What sets this volume apart is its integrative perspective: it combines theoretical clarity, policy analysis, and empirical depth to trace the journey of climate finance from conception to implementation. It also explores underexamined topics such as carbon as an anchor asset and the role of climate finance in global monetary dynamics, including RMB internationalization. Designed for scholars, graduate students, policymakers, and financial professionals, this book provides clear conceptual frameworks and evidence-based insights. It is particularly valuable for readers interested in finance-driven climate transitions and the institutional design of net-zero finance. Key features include:1. Provides a comprehensive analysis of climate finance instruments and regulatory systems. 2. Offers a structured treatment bridging theory, policy, and market practice.
