As a first-time effort in India, the Green Vehicle Rating (GVR) serves as a consumer information tool that identifies high to low performing vehicle models in 2 & 3-wheeler categories, in terms of the negative impacts of greenhouse gases and criteria pollutants released from the tail pipe. The rating is meant to inform the choices that consumers make while purchasing vehicles. Along with a comparative analysis of models, the rating shows the external costs of energy-related pollution impacts from vehicle exhausts—both GHGs and air pollutants. The rating evaluates the tail pipe emissions of twenty 2-wheeler models, and two 3-wheeler models. This pool includes products from Bajaj, Hero Motors, TVS, Honda, Suzuki, and Eicher. All the models currently follow Bharat Stage IV emissions norms.
