Abstract:

The Green Vehicle Rating (GVR) is the country’s only vehicle rating system based on environmental performance and functions as a consumer information tool. It is important to rate and compare the EV models alongside ICE-based models under the GVR programme. GVR uses a ‘damage cost’ methodology to estimate the costs of the negative environmental and health-related impacts of criteria pollutants and GHGs. This paper presents the approach, assumptions, and analytical process used to calculate the ratings in GVR Phase 2, launched in 2021 for both ICE vehicles and EVs. GVR broadly serves three functions i.e. (i) To enable buyers to find vehicle model ratings based on their environmental performance (ii) To inform/ educate the buyers about the health and environmental costs of vehicular emissions (iii) To inform the buyers about the real cost of owning the vehicle.
