The nationally determined contribution (NDC) is a fundamental architecture of the 2015 Paris Agreement. The 194 signatory Parties to the Agreement each selected their own preferred strategy for climate change mitigation and adaptation (M&A), resulting in a wide range of individual strategies. As the implementation of these strategies begins, it is essential for policymakers, practitioners, and analysts to develop a coherent knowledge base for the NDC-centered processes and the principles and practices for reducing and removing greenhouse gas emissions. The forest sector is a key focus for many Parties and, in this context, it is important to understand the processes, principles, and practices pertinent to forest sector M&A. The goal of this book is to address the major issues encountered in global forest carbon accounting and assessment, as well as climate governance. Included are the differential potentials for carbon sequestration within various forest ecosystems as well as for storage within different harvested wood products, the joint production of timber and carbon, the measurement and impact of forest carbon offsets and credits, and carbon leakage induced by trade. This introduction outlines these issues and the organization of the book.
