Study Reveals Overlooked Emissions from CNG Vehicles, Calls for Policy Shift

A recent study under the TRUE Initiative highlighted that real-world vehicle emissions are significantly higher than lab results, with CNG vehicles emitting high nitrogen oxides (NOx). The study suggests a policy focus on actual emissions and promotes zero-emission vehicles. Auto LPG emerges as a viable alternative.

Real-world vehicle emissions surpass laboratory findings, and CNG vehicles, previously considered cleaner, emit significant nitrogen oxides (NOx), according to a new study.

Part of The Real Urban Emissions (TRUE) Initiative, the research used non-intrusive remote sensing technology in Delhi and Gurugram to measure on-road vehicle emissions. The International Council on Clean Transportation (ICCT) found that NOx emissions from BS-VI private cars were 81% lower than BS-IV cars, and BS-VI buses emitted 95% less NOx compared to their BS-IV counterparts.

However, CNG vehicle fleets emitted high NOx levels, refuting the belief that CNG is a 'clean' alternative. This discrepancy points to the need for policies focused on actual emissions rather than lab results and a shift towards zero-emission vehicles. As part of this shift, Auto LPG is proposed as a cleaner, cost-effective alternative fuel that aligns with India's environmental goals.
