Volkswagen, the German automotive giant, recently entered the world of scandal after reports emerged that cars manufactured emitted illegal pollutants into the air. The company has proposed plans to remedy this problem but California Regulators has rejected VW's plans.

Volkswagen has previously admitted that they used specialized software installed into the cars sold in the United States. The software allowed diesel powered engines to pass emissions test. Further tests have found that the emissions created 40 times as much nitrous oxides into the atmosphere. 

To remedy the situation, VW authorities have apologized for the issue and promised to provide a solution to CARB. The federal Environmental Protection Agency also supports CARB's decision. The rejection of the plans required the company to indicate how the vehicles would be repaired, how quickly and the results. 

The California Air Resources Board has rejected Volkswagen plans for repairing the 2.0 liter passenger cars manufactured between 2009 and 2015. CARB indicated that the plans were unacceptable and lacked detail. The regulation board further explained that the plans did not appropriately address concerns regarding emissions, performance and safety.

Now, VW is back to the drawing board and the scandal caused a 25% decrease in sales for the second half of 2015. The company was forbidden to sell diesel engine cars.

Dave Clegern, a CARB authority, explains further..

It's easier to say what they were not proposing than what they were. They just didn't give us enough information to determine what they were proposing would actually work... Getting unclean vehicles off the road is our preference.

CARB still hopes that VW will come up with a solution. If reparations are not possible then one of the solutions would be for VW to buy back the affected cars from the current owners which aims to eliminate or at least reduce the illegal emissions on the road, reports  have indicated.
