The Renault-Nissan Alliance claims to have sold its 100,000th zero-emission car.

Electric cars from Renault and Nissan have driven approximately 841 million zero-emission kilometres − enough to circle the earth more than 20,000 times. Together, they represent 53 million litres of oil saved and 124 million kg of CO2 that have not been emitted.

"The age of the mainstream zero-emission vehicle is here," said Renault-Nissan Alliance chairman and CEO Carlos Ghosn. "We expect demand to keep growing as the charging infrastructure develops – and we remain 100% committed to zero-emission technology for the long term."

Renault-Nissan has sold more zero-emission cars than all other major automakers combined.

The very first EV from the Alliance is a Nissan Leaf owned by engineer Olivier Chalouhi in California’s Silicon Valley. He bought the Leaf when it debuted in December 2010.

The 100,000th customer was American graduate student Allison Howard, who became an owner of Nissan Leaf earlier this month and drives the car to Kennesaw State University in Atlanta, Georgia.

"It just drives perfectly. It’s so cool. I love it!" said Howard.

"The fact that it’s all electric and I don’t have to spend money on gas as a college student, that’s great," she added.
