Bharat Stage VI (BS VI) emission norms are already introduced in India from 1st April 2020. The implementation of BS VI emission standards essentially brings Indian motor vehicle regulations on par with most stringent International standards. The BS VI regulation also mandated Real Driving Emission (RDE) measurement with objective to limit regulated pollutants esp. NOX & PN during real use of vehicle. For M1 passenger vehicles Carbon Dioxide (CO2) emissions measured in Lab is also regulated under CAFÉ (Corporate Average Fuel Economy) however, CO2 emission during Real on Road Driving is not regulated. So, this study was carried out to compare CO2 on real road traffic conditions with standard lab conditions. This study was done on a set of BS VI compliant vehicles with diverse characteristic such as engine capacity, fuel type. These vehicles were tested on a chassis dynamometer in a vehicle-emissions laboratory under well-defined & controlled ambient conditions for temperature and humidity as per regulation specified in AIS 137 part 3 and then the same group of vehicles were tested on road using PEMS (Portable Emission Measurement System) equipment as per regulation specified in AIS 137 Part 3 Chapter 20. On road tests were carried out on working day during working hours in the city of Pune. This paper analyses & summarizes the change in CO2 emission of these M1 passenger vehicles from lab to on road running, on the basis of different vehicle characteristics and also on the basis of different traffic condition i.e., city & highway traffic.
