The government has set ambitious targets, such as achieving 30% electric mobility by 2030, underlining the critical role of EVs in the country’s climate strategy.

Understanding the climate impact of EVs

India’s transportation sector contributes approximately 12% of the nation's energy-related CO2 emissions, making it a significant target for emission reduction strategies. EVs are touted as a crucial solution, but their true climate impact depends on several factors, including energy efficiency and the carbon intensity of the electricity grid.

Energy efficiency and lifecycle emissions

EVs are significantly more energy-efficient than internal combustion engine (ICE) vehicles, consuming three to seven times less energy per kilometre travelled. For instance, electric scooters are more than seven times more efficient than their petrol counterparts.

However, the climate benefits of EVs in India are tempered by the carbon intensity of electricity, which is predominantly generated from coal.

The lifecycle emissions of EVs, including those from battery manufacturing and disposal, must also be considered. EV batteries are resource-intensive to produce, involving materials like lithium, cobalt, and nickel, which have their own environmental and social impacts.

According to Centre for Social and Economic Progress’s (CESP’s) recently published report, Demystifying the Climate Benefit of EV Transition in India, the emissions associated with battery production add about 10 to 15 grams of CO2 per kilometre to an EV’s footprint, depending on the vehicle type. This highlights the need for advancements in battery technology and recycling processes to further reduce the lifecycle emissions of EVs.

Comparative emissions

It is estimated that the operational emissions of EVs based on the weighted average emission factor of India’s grid electricity, approximately 715 grams of CO2 per kilowatt-hour. When adjusted for transmission and distribution losses, the emissions from EVs, while lower than those from ICE vehicles, remain significant. This calculation underscores the importance of decarbonizing the electricity grid to maximize the climate benefits of EV adoption.

Regional disparities in EV benefits

One of the report’s key findings is the substantial regional variation in the climate benefits of EVs across India. The carbon footprint of EVs is heavily influenced by the local electricity supply mix. For example, cities like Bengaluru, with a higher share of renewable energy, offer greater reductions in EV-related emissions compared to cities like Kolkata, where coal dominates the energy mix.

Case studies: Bengaluru vs. Kolkata

In Bengaluru, the integration of renewable energy sources like solar and wind into the grid has resulted in a cleaner electricity supply, significantly reducing the emissions associated with EV charging. In contrast, Kolkata’s heavy reliance on coal-fired power plants leads to higher emissions from EVs. The report reveals that the CO2 emissions from EVs in Kolkata can be as much as 82% higher than in Bengaluru, highlighting the need for region-specific strategies to enhance the environmental benefits of EVs.

State-level policies and incentives

States like Maharashtra and Tamil Nadu have introduced specific policies and incentives to promote EV adoption. Maharashtra, for example, offers subsidies for EV purchases and has plans to develop extensive charging infrastructure. Tamil Nadu has positioned itself as a manufacturing hub for EVs, attracting investments from major automakers.
