While the EU is the world’s biggest gas importer, its dependence on Russian gas has been a growing concern. Gas stress tests carried out in 2014 demonstrated the vulnerability of several member states in case of gas disruptions, along with the need for more internal cooperation within the EU. At the same time, the transition to a sustainable energy system, which would see an increase in energy efficiency and reduction of fossil fuels - in heating, for example - could be a win-win for climate and energy security. As part of the Energy Union agenda, the EU Commission tabled a package of proposals in February to improve energy - namely gas - security. The proposals comprise a revision of the Security of Supply Regulation, a Decision on Inter-Governmental Agreements (IGAs) and Strategies on Liquefied Natural Gas and Storage and Heating and Cooling. This Policy Dialogue discussed the impacts of the Commission’s proposals on gas imports and use in Europe, how these proposals can help to address barriers to security of supply, the implications for Russian export strategy and how the measures taken can be adequately aligned with the EU’s climate and energy objectives.
