European gas legislation is becoming increasingly complex and detailed since the introduction of an energy chapter by the Lisbon Treaty and the adoption of the third internal market package in 2009. The voluminous body of binding legislation is completed by guidelines, network codes, and interpretative documents issued by the European Commission, the Agency of Energy Regulators, and the System Operators. Consensus and soft law does not only bind its authors, but often leads to future consolidation through formal legislation. This book offers an up-to-date compendium of all EU gas legislation and soft law, including the Commission proposals for new legislation. It brings together gas specific provisions, as well as horizontal provisions on other energy sectors and pertinent legislation concerning environment and energy efficiency, trans-European networks and infrastructures, trade policy and international organizations, market integrity and transparency, and research and development. Such a comprehensive approach reflects the increasing importance of gas, beyond its traditional role for heat and power generation, as a bridging technology in the perspective of more renewable forms of energy. Gas is not only an energy source, but serves also as an energy carrier and a means for energy storage. The book reproduces all pertinent provisions in a user-friendly way.
