CNG vehicles emit more pollutants than you think: Study from Delhi-Gurgaon shows

A recent study revealed that vehicle emissions on the road are significantly higher than in lab tests. BS-VI cars emit 81% less NOx than BS-IV vehicles, and buses show a 95% reduction. CNG vehicles, often seen as cleaner, also emit high levels of NOx. The study highlights the need to focus on real-world emissions to improve air quality.
