This book offers an interdisciplinary examination of how legal frameworks influence sustainability in entrepreneurship. Moving beyond traditional approaches that treat regulation and innovation as opposing forces, it explores how laws and policies can both constrain and stimulate entrepreneurial activity aimed at achieving long-term economic, social, and environmental goals. Through research-informed case studies, the book reveals how entrepreneurs can align with regulatory expectations while driving meaningful change. Featuring contributions from experts in law, finance, and sustainability, the first part of this two-volume set focuses on institutional innovations, green public policies, and environmental governance mechanisms that address climate change, resource management and social equity. Emphasis is placed on the intersection of law, policy and organizational sustainability at the global level. It is an ideal resource for scholars, policymakers, and practitioners seeking to understand and shape the future of sustainable enterprise.
