The document summarizes ENGVA's response to the European Commission's Green Paper on energy security. It argues that the Green Paper raises questions that have already been answered in previous Commission reports, such as the need to reduce dependence on imported oil through alternative fuels like natural gas. The document calls for the Commission to take action on these existing recommendations by developing an action plan and strategy, and to provide more support for natural gas vehicles through policy leadership, regulatory actions, research funding, and balanced communications about alternative fuels.
