The idea of developing the book Global Law: Legal Answers for Concrete Challenges has its origin in the intense internationalization process of São Paulo Law School of Fundação Getulio Vargas (FGV DIREITO SP). The fact that FGV DIREITO SP has received a considerable number of foreign visiting professors over the last eight years in its Global Law Program and has participated actively in the constitution and development of the Law School Global League (LSGL) were the starting point for the structuring of this book. The main objective of the Global Law: Legal Answers for Concrete Challenges is to allow the discussion of themes considered global from different points of view, but with an emphasis on the Brazilian vision. On the other hand, the editors believe that there is a growing public of lawyers and non-lawyers interested in the themes and type of approach of this book, not only in Brazil, but also in many other jurisdictions. The Global Law: Legal Answers for Concrete Challenges is composed of four sections that put together related papers with thematic affinity. These sections are: i) Regulation and the Relationship between Public and Private Sectors; ii) Corruption Systems and Systemic Corruption; iii) Environment and Human Rights; iv) Globalization: Technological Innovation and New Legal Paradigms. The editors made a brief explanation at the beginning of each section to give the reader an opportunity to be acquainted with the theme and main characteristics of each paper. It is important to emphasize the pedagogical character of this book.
