The once-reliable river of emission-credits cash Tesla

It is pooling its emissions credits with both brands, which gives them huge EV volumes from the Renault Zoe and the Nissan Leaf. So far this year, 11 percent of Renault’s passenger car sales in Europe have been EVs.

According to a report by the European Electric Car Report, Renault now has so much confidence in its ability to meet its EU7 emissions targets that it has thrown open invitations to join its CO2 emissions pool to other auto makers.

In a document published by the European Commission, Renault has given a
