A recent study by IIT Roorkee and the International Council on Clean Transportation (ICCT) warned against delaying BEV adoption in anticipation of a cleaner grid.
More on the News:
- A recent study by IIT Roorkee and the International Council on Clean Transportation (ICCT) found that Battery Electric Vehicles (BEVs) in India produce up to 38% less carbon dioxide equivalent (CO₂e) per kilometer than Internal Combustion Engine (ICE) passenger cars.
- However, the study points out that three main factors—grid carbon intensity, lab test assumptions and real-world driving conditions—together explain almost 75% of the differences in car emissions.
- This research is one of the first detailed reviews of the full life cycle greenhouse gas (GHG) emissions from passenger vehicles in India.
- It combines findings from six major studies to give a clear picture of what affects emissions and how they can be reduced.
Key Findings of the report
- The study highlighted that Battery Electric Vehicles (BEVs) consistently produce lower life cycle greenhouse gas (GHG) emissions than Internal Combustion Engine (ICE) vehicles and Hybrid Electric Vehicles (HEVs).
- This advantage is most clear when studies use realistic energy use data and reflect actual driving conditions.
- It also warned against postponing BEV adoption while waiting for a cleaner electricity grid, as ICE vehicles bought today will keep emitting for 10–15 years, while BEVs will become even cleaner over time as the grid improves.
- The study also pointed out that there is a gap between lab test results and actual fuel use in Hybrid Electric Vehicles (HEVs) and stressed the importance of using real-world correction factors for accurate emissions tracking.
- It found that BEVs consistently show the highest energy efficiency in real-world use.
- To ensure cleaner and more efficient vehicles on Indian roads, the study called for strict fuel efficiency standards and the inclusion of real-world adjustments—especially for BEVs, where charging losses are often ignored.
- The study also noted that many evaluations overlook land-use changes, leading to an underestimation of emissions from biofuels.
- For example, emissions from diesel production ranged from 8 to 22 grams of CO₂ per kilometre, depending on whether land-use change was included in the analysis.
- To tackle these challenges, the study recommended several policy actions:
- speeding up the adoption of BEVs alongside efforts to clean up the power grid
- strengthening fuel efficiency standards
- mandating on-board fuel and energy consumption meters (OBFCMs) to improve transparency and data accuracy across all vehicle types
- incorporating land-use change impacts in biofuel life-cycle assessments to avoid underestimating their environmental cost.
- Amit Bhatt, India Managing Director at ICCT, stressed the critical role of BEVs in cutting emissions.
- He said, “Electric vehicles are more efficient than ICE vehicles and become even cleaner as India’s power grid gets greener. Delaying BEV adoption risks locking in long-term emissions from ICE vehicles.”
- Sunitha Anup, researcher at ICCT and co-author of the study, advised that future life-cycle assessments in India should consider the changing electricity grid over a vehicle’s lifetime, real-world energy consumption and land-use emissions from biofuels.
- These factors are essential for shaping effective clean transport policies. She stated, “It shows that what we assume today shapes the climate impact tomorrow.”
