On 19 December 2007, the European Commission proposed legislation to reduce the average carbon dioxide (CO2) emissions of new passenger cars to 120 grammes per kilometre by the year 2012. The proposed legislation is the cornerstone of the European Union's strategy to improve vehicle fuel economy. Other benefits for consumers include the improvement of energy security and the promotion of eco-innovations. The proposal also aims to safeguard the already competitive automotive sector through provisions that will stimulate the development and deployment of cutting edge automotive technologies.
