New Delhi, Dec 16, 2025 — A new study has found that Electric Vehicles (EVs) significantly outperform traditional petrol-powered cars in reducing greenhouse gas emissions over their entire lifecycle — from manufacturing to operation and disposal. motormitra.in The findings add more weight to the argument that EVs are a key tool in the fight against climate change.

The report, conducted by researchers at IIT Madras in collaboration with energy and transportation labs, compared full lifecycle emissions of battery Electric Vehicles (BEVs) and internal combustion engine vehicles (ICEVs) under India’s current energy conditions. times.motormitra.in The results make a clear case for EVs’ environmental benefits — even on a grid that still relies heavily on fossil fuels.

Big Difference Over Vehicle Lifetime

According to the study, a petrol car emits about 53.84 tonnes of CO₂ equivalent over a journey of 300,000 km, while an Electric Vehicles emits just 33 tonnes over the same distance under India’s current electricity mix. Auto.MotorMitra This means EVs produce roughly 40% fewer lifecycle emissions than petrol cars when all stages are considered.

The lifecycle assessment includes:

• Vehicle manufacture: Electric Vehicles production generally has slightly higher emissions due to battery manufacturing.
• Operation: Electric Vehicles emit no tailpipe CO₂, and total emissions depend on the electricity used for charging.
• End-of-life and recycling: Post-use emissions and recycling also factor into total lifecycle impact.

Cleaner Electricity Boosts EV Advantage

The report highlights that as India increases its use of renewable energy — such as solar and wind — the emission advantage of Electric Vehicles will grow even stronger. If Electric Vehicles are charged with fully renewable electricity, their lifecycle emissions can drop to nearly negligible levels. times.motormitra.in In comparison, petrol cars have no such scope for emission reduction during operation.

This conclusion aligns with global research showing the same trend. A recent international study found that battery Electric Vehicles sold in Europe today emit significantly less greenhouse gas over their lifetime — up to 73% lower than gasoline counterparts — largely because of renewables in the electricity mix and better energy efficiency. motormitra.in

Implications for Climate and Policy

Transport is one of the largest contributors to air pollution and climate emissions worldwide. Switching from petrol cars to electric ones could cut overall emissions by large margins — especially as national grids decarbonise. Auto.MotorMitra Experts say this supports stronger policies promoting EV adoption, charging infrastructure expansion, and renewable energy investment.

Despite the higher emissions during manufacturing — mainly from battery production — lifecycle analyses consistently show that EVs overtake petrol cars in emissions savings within the first few years of use. This “break-even” point generally occurs after the initial years of driving. motormitra.in

Clean Mobility Push in India and Beyond

India’s automotive sector is rapidly transitioning toward electrification, supported by government incentives and growing consumer interest. Auto.MotorMitra Analysts say that these latest lifecycle emission results will help policymakers make the case for faster adoption of Electric Vehicles — not just for urban air quality, but for long-term climate benefits.

Overall, the evidence from multiple lifecycle studies makes it clear: Electric vehicles are cleaner over their full lifetime than petrol cars — and will only become greener as electricity generation shifts toward sustainable sources motormitra.in
