Formula and Methodology
Fuel or energy units used is distance divided by mileage or efficiency. CO2 emission is units used multiplied by the emission factor entered.
The calculator also shows monthly, annual, per-kilometre and tonnes of CO2 estimates.
The calculator also shows monthly, annual, per-kilometre and tonnes of CO2 estimates.
Worked Example
Example: For 1,000 km at 15 km per unit and a 2.31 kg CO2 emission factor, the calculator estimates about 154 kg CO2 for the period.

Common mistakes to avoid
Do not use showroom mileage if your real-world mileage is lower. City traffic, AC usage, driving style, load and road conditions can change fuel use. For EVs, use actual charging efficiency or electricity consumption when available. If you have a source-specific emission factor, replace the default value.

India-specific notes
Indian fuel quality, traffic patterns, electricity mix and vehicle efficiency can vary widely by city and usage. The result is best used for comparison and awareness, not formal compliance reporting. For official ESG or fleet reports, use verified fuel bills, odometer readings and approved emission factors.
FAQs
Yes. The inputs, labels and result formatting are designed for Indian users and show INR values where money is involved.
The result is a planning estimate based on the values you enter. Always verify final amounts with the relevant bank, employer, tax advisor, school, builder or official document.
