The Renault-Nissan Alliance is to provide 200 pure electric vehicles for the United Nation’s COP21 climate conference in Paris, which runs from November 30 to December 11.

The manufacturers are the official passenger car providers to the event and will provide the world’s largest electric-vehicle fleet ever to an international conference.

Together, the vehicles are expected to cover more than 400,000km while transporting delegates during the 21st annual Conference of Parties (better known as COP21).

More than 20,000 UN participants from 195 countries are expected to attend the summit.

The COP21 car fleet will feature the Renault Zoe, the Nissan Leaf and the seven-seater Nissan e-NV200 van and will be available to shuttle delegates 24 hours, seven days a week to and from the Le Bourget conference venue, as a complement to public transportation.

This will be the first time the UN will use a zero-emission or 100% electric fleet for its entire passenger-car shuttle at a climate summit.

The 100% electric cars will be driven by a team of 200 professional drivers and 200 volunteers from Renault and Nissan.

Renault-Nissan Alliance will set up network of 90 quick and standard charging stations in strategic locations with French electric utility company EDF powered by low-carbon electricity.

The residual emissions will be offset under an accredited U.N. carbon offsetting program.
