From October 1st of last year through September 30th this year, a look at the Zero Emission Vehicle credits (ZEV credits) for various automakers in California reveals that Nissan has actually pulled ahead of Tesla in terms of credits withdrawn.
As Green Car Congress reports, things are very different from the numbers generated through the previous year-long period. This year, Nissan withdrew about 663.6 credits to Tesla’s 650.2. The previous year, Tesla transferred out about 1311.5 credits, compared to the next-biggest withdrawal of 507.5 credits by Toyota.
The automaker ZEV credits are a way for the California Air Resources Board to keep tabs on the proportion of zero emissions vehicles on the road in the state. Moving a larger percentage of green vehicles in California allows the manufacturer to acquire credits, which they can put toward attaining some lenience on future CARB requirements.
Or, in the case of Tesla, the manufacturer can sell the ZEV credits to other automakers. The results from this year represent a total 3.5 million cars – from hybrids to EVs, fuel cell cars to those using low-emissions petrol powerplants. Naturally, a positive balance of ZEV credits represents a compliance with CARB standards, where a negative balance indicates a failure to comply.
This year, no automaker has acquired a negative balance of ZEV credits.
