This document describes a joint research program on shale gas between 26 research institutes from 15 European member states. The program aims to establish an independent knowledge base on shale gas in Europe by evaluating existing technologies and methodologies. It identifies the main drivers for the program as the expected continued importance of fossil fuels in Europe's energy mix, the potential role of shale gas in increasing energy security and lowering costs, and the need to address public environmental concerns. The program consists of 5 sub-programs that will assess shale gas resources, technologies for safe and efficient exploitation, environmental impacts and footprint, energy/carbon efficiencies and emissions, and strategies for public engagement. A total of 185 person-years of expertise and resources are committed across the 26 participating
