Electric vehicles (EVs) have a lower overall environmental impact than internal combustion engine (ICE) cars, with EVs generating approximately 37-40 tons of CO2 emissions over their lifetime compared to 59 tons for ICE cars. Despite concerns about the CO2 emissions from battery manufacturing and electricity sources, even EVs charged from the least renewable sources perform better than ICE vehicles. Improvements in EV production efficiency and the shift to renewable electricity for charging will enhance their environmental benefits further.
Demystifying the myth
- 1. Demystifying the myth Are EVs environment friendly only if charged via electricity generated from renewable resources? Restricted
- 2. On point! Environmental impact of: 1.Manufacturing 2.Fuel Usage
- 3. Manufacturing of Electric Vehicle Most important component is Lithium Ion in battery which is obtained from mineral rich brine by mining process. 750 tons of brine gives 1 ton of Lithium Average EV manufacturing could be responsible for up to 7-8 tons of CO2 emissions. Same figure for long range EV comes out to be 17 tons of CO2 emissions.
- 4. Manufacturing of IC Engine Cars IC engine car manufacturing is far more advanced with refined and optimized processes. Considering the journey from mining ore to ready car, average IC engine car is responsible for up to 7 tons CO2 emissions
- 5. Fuel Usage A car runs 18000 km per year A car is usable for 10 years Fuel economy for IC engine car is 12km per liter Average range of EV is 250km per full charge Assumptions for the sake of apple-to-apple comparison:
- 6. Fuel Usage for EVs Even if an electric vehicle is charged from worst source of electricity, it would be responsible for up to 2 tons of CO2 emissions per year
- 7. Fuel Usage for IC Engine Cars IC engine car exhaust is responsible for up to 5.2 tons of CO2 emissions per year. So, 52 tons of CO2 emissions in the entire life span is imminent. But the petrol/diesel must be extracted from crude oil and refined. • - Average daily oil production is 95 million barrels which accounts for 770 million tons of CO2 emissions • - Single refinery is responsible for 280 billion tons of CO2 emissions in a year
- 8. Verdict! Even if we ignore the emissions due to processing of petrol/diesel, electric vehicles are far better than IC engine cars. Origin Electric Vehicle IC Engine Car Manufacturing 17-20 7 Fuel Usage 20 52 Total 37-40 59 CO2 Emissions (in tons)
- 9. Are EVs environment friendly only if charged via electricity generated from renewable resources? A big NO! EVs are far better than traditional cars when it comes to environmental impact. As EV production gets more efficient, its environmental impact will get better. Battery charging via electricity generated from renewable resources will improve environmental footprints of EVs.
