The European Energy Law Report XV presents a selection of the most important developments in the field of international, European Union (EU) and national energy and climate law as discussed at the 32nd and 33rd European Energy Law Seminars, which took place in The Hague (the Netherlands) in May 2022 and November 2023 respectively.

Although a wide range of topics were discussed at the seminars, four general themes emerged from the presentations. They range from internal market and climate change developments (Part I), the governance of energy suppliers and the supply chain (Part II), the relationship between the EU and third countries (Part III) and, finally, challenges affecting the energy system and system security (Part IV). These issues are discussed in fourteen chapters divided over four parts of this volume. Noticeably, the impact of the war in Ukraine is a recurring matter in several chapters.

INTERNAL ENERGY MARKET AND CLIMATE CHANGE: JUDICIAL AND LEGISLATIVE DEVELOPMENTS

Part I offers a review of some landmark legislative and judicial developments with regard to the internal energy market and climate change. Apart from a review of EU case law in the energy sector, this part also offers a review of the effects of climate change litigation on energy companies and a review of the EU ‘Fit for 55’ legislative package.
