Created in 1999, the Renault-Nissan Alliance is a car group responsible for one in 10 cars globally, with 2012 revenues of US$ 170 billion. The Alliance employs nearly 450,000 people in almost 200 countries worldwide. Renault and Nissan are run as separate companies but united through cross-shareholding, a shared focus on results-driven synergies, cross-cultural management and respect for individual brand and corporate identities. The Alliance has a flexible business platform and has expanded to include collaborations with Germany's Daimler, China's Dong Feng and Russia's AvtoVAZ, among others. Renault and Nissan are the only automakers mass-producing and selling zero-emission vehicles, including the Nissan LEAF and Renault Kangoo ZE van, which are 100% electric and can be fully recharged with purely renewable energy. The Alliance is helping to build a zero-emission infrastructure around the world and has agreements with over 100 cities, states and countries that are working to establish the infrastructure and market conditions that will help make electric vehicles affordable and convenient.
