The document discusses gas supply issues in Europe and proposes a transparency regime. It notes that Russia has significant surplus pipeline capacity to export gas to the EU but only exported around 113 billion cubic meters physically in 2012 despite contracted volumes of around 158 billion cubic meters for 2020-2025. It provides the example of future gas supply to Lithuania being at risk of interruption. The document proposes a scheme called the Energy Transparency Regime for Gas based on online data interchange of pipeline pressure, incoming volumes, and outgoing volumes as an early warning mechanism to increase transparency of gas flows between producers, transmitters, and consumers.
