Rising gas prices have constrained CNG penetration in commercial vehicles to 9-10 per cent in the current fiscal from peaks of 16 per cent, Icra Ratings said on Friday.
A spurt in global energy prices has led to a 70 per cent jump in the price of CNG in the last one year. This has narrowed the gap between the fuel and diesel, blurring the incentive to shift to the cleaner fuel.
In a statement, the rating agency said CNG penetration in the domestic commercial vehicle (CV) sector has witnessed a decline in the current fiscal, especially in the MCV truck segment.
