BYD e6 Electric Vehicle

Electric vehicles typically produce fewer carbon emissions compared to ICE vehicles. The carbon footprint for the BYD e6, based on its energy consumption and the electricity mix, is calculated as follows:


  • Average Carbon Intensity of Electricity in India:

    ~0.82 kg CO2 per kWh (source: International Energy Agency)

  • Total Energy Used: 11,052 kWh

  • Total Carbon Emissions: 11,052 kWh X 0.82 kg CO2/kWh = 9,061.44 kg CO2

    ICE Vehicle

    An ICE vehicle with an average fuel efficiency of 12 km per Litre and a fuel cost of 89 per Litre produces significantly more emissions:

  • Average Carbon Emissions per Litre of Diesel:

    ~2.68 kg CO2 per Litre

  • Fuel Consumption: 6,119 Litres

  • Total Carbon Emissions: 6,119 Litres X 2.68 kg CO2/Litre = 16,402.92 kg CO2

    Comparison of Carbon Footprints

  • BYD e6: 9,061.44 kg CO2

  • ICE Vehicle: 16,402.92 kg CO2

    Carbon Credits

    Calculation of Carbon Credits

    Carbon credits can be earned by reducing emissions compared to a baseline. In this case, the baseline is the ICE vehicle's emissions:

  • Emission Reduction: 16,402.92 kg CO2 (ICE) – 9,061.44 kg CO2 (BYD e6) = 7,341.48 kg CO2

  • Carbon Credits Earned: 7.34 credits (1 credit = 1 ton CO2)

  • Total Value: 7.34 credits X 1,000 = 7,340

    Potential Financial Benefits

    The financial value of carbon credits varies, but assuming a

    market rate of 1,000 per credit:


    The BYD e6 electric MPV has demonstrated remarkable reliability, cost-efficiency, and a reduced carbon footprint over two years and 73,432 kilometers. With low energy consumption, minimal maintenance needs, robust performance, significant carbon emission reductions, and potential carbon credits, it is a viable option for sustainable and economical transportation. Its durability, especially in terms of tire and brake longevity, makes it suitable for both personal and commercial use. Comparing it to a conventional ICE vehicle, the BYD e6 offers substantial savings and environmental benefits, making it a worthwhile investment for environmentally conscious and budget-savvy consumers.

    Comparison with an ICE Vehicle Fuel and Maintenance Costs

    An ICE vehicle with an average fuel efficiency of 12 km per Litre and a fuel cost of 89 per Litre:

  • Fuel Consumption: 6,119 Litres

  • Fuel Cost: 544,591

  • Maintenance Cost: 72,500

  • Insurance Cost: 61,842

  • Total Cost of Ownership: 678,933

  • Cost per Kilometer: 9.24

    Cost Savings with BYD e6

  • Total Savings: 484,249 (678,933 – 194,684)

  • Savings per Kilometer: 6.59 (9.24 – 2.65)
