Sustainable mobility has been given a boost in France by the results of the country's biggest ever trial of all-electric vehicles. Supported by Renault-Nissan, the SAVE (Seine Aval Véhicules Électriques) initiative was conducted in the Yvelines region near Paris between March 2011 and December 2012, and resulted in the installation of 130 charging stations and 45.5 tonnes of CO2 avoided.
