Methodology notes

  • Educational estimate only — not financial, tax, or purchase advice.
  • Petrol CO₂ is approximate tank-to-wheel combustion; excludes refining and logistics.
  • EV CO₂ uses an average India grid factor; home solar or greener tariffs would lower it.
  • Does not model battery manufacturing, tyre/brake wear, or full lifecycle assessment.
  • Petrol prices, tariffs, and real-world efficiency vary by city, season, and driving style.
  • Ethanol-blended petrol (e.g. E20) slightly changes energy content and CO₂ vs pure petrol — ignored for simplicity.
