The Tata Nexon and the Maruti Suzuki's hybrid Gran Vitara were analysed. The EV emits 187 grams of carbon dioxide per kilometer of use, while the hybrid is at 167. And if you're wondering why EVs aren't coming out trumps then remember emissions aren't just about what comes out of the tailpipes alone. In India we are still quite heavily reliant on thermal power for our needs. 80% of it comes from burning coal so each time you juice up your EV you burn a little bit more coal giving way to increase carbon dioxide emissions.
