The current framework of EU regulation concerning capital markets is complex and partly inconsistent in the way that it is applied in the various Member States. Through the Capital Markets Union (CMU) project the European Union is pursuing the goal of establishing a true single market for capital in Eu-rope. Regulating EU Capital Markets Union: Market Conduct and Corporate Disclosure in a European Code is the second of a two-volume series proposing the codification of EU legislature as a way to estab-lish this goal.This volume focuses on a reform of market abuse, short selling, corporate disclosure and public takeovers. In doing so, it considers the fact that financial markets law is now characterized by the idea of promoting sustainable investments. In addition, the book proposes to introduce union wide civil liability and to har-monise administrative sanctions. A higher degree of harmonisation will foster greater market integration and remove barriers to cross-border activity.A holistic codification follows the framework of Better Regulation, namely the principle of proportionality and of a comprehensive and coherent approach. The book proposes relief of regulatory burden for com-panies listed on regulated markets to incentivize growth companies to go public. Codification allows for a comprehensive approach, thus the consideration of all affected aspects. Furthermore, a codification fits into the objective of following a coherent approach- codification is consistent with the high-level and long-term policy objectives of the Capital Markets Union and the Savings and Investment Union. --
