This book analyzes the roles of technologies and their prevalence in implementing intended nationally determined contributions (INDCs), estimates the economic impacts and co-benefits of INDCs, clarifies the gaps between the current INDCs and the long-term target of the Paris Agreement to stay well below 2 °C, and investigates measures to narrow these gaps. Analyses of the INDCs of six Asian countries with the Asia-Pacific Integrated Modeling/Computable General Equilibrium (AIM/CGE) model are introduced. The book is also intended to support climate policy analyses by introducing methodologies to analyze the economic impacts of climate policies using AIM/CGE. These analyses show the feasibility of INDCs, their implications for the long-term climate goal, and the challenges to increase the levels of ambition of INDCs.
