Every number traces to a source.
There is no model guessing your footprint. Prithvi multiplies what you log by published, India-specific emission factors. Here is every factor, its unit, and where it comes from — so any result can be checked by hand.

Worked example
A 12 km petrol-car commute in Maharashtra: 12 km × 0.155 kg/km = 1.86 kg CO₂. 8 kWh of home electricity in the same state: 8 × (0.71 × 1.05) = 5.96 kg CO₂, then divided across your household. Nothing hidden.
