Climate Finance develops a comprehensive framework to understand financial pathways supporting the energy transition toward carbon neutrality. Combining theoretical and empirical analyses, it addresses the massive investment needs identified by the IEA and the structural challenges posed to existing financial systems. The book emphasizes the necessity of financial innovation, institutional restructuring, and mechanisms to mobilize private capital. Bridging academia and policymaking, it integrates finance theory with energy sector practice to inform research and guide decision-makers.
