About the Carbon Footprint Calculator
What is the Carbon Footprint Calculator?
This carbon footprint calculator estimates your yearly greenhouse gas emissions using emission factors for India, including the grid electricity factor.
Household electricity and cooking gas are shared across members; travel and diet are yours alone.
How to use the Carbon Footprint Calculator
- People in the Household (sample: 3)
- Household Electricity (kWh a month) (sample: 250)
- LPG Cylinders a Year (14.2 kg) (sample: 8)
- Your Car Travel (km a month) (sample: 500)
- Your Two-wheeler Travel (km a month) (sample: 150)
- Bus / Metro / Train (km a month) (sample: 200)
- Flight Hours a Year (sample: 4)
- Your Diet (sample: Non-vegetarian (chicken, fish))
- Press Calculate Carbon Footprint (results also refresh as you type). The result card shows the Your Annual Carbon Footprint, along with Per month, Largest source, Compared with the Indian average (about 2 t) and Compared with the world average (about 4.7 t).
Formula used
Footprint = Σ (Activity × Emission factor)
- Electricity = 0.72 kg CO₂ per kWh (CEA grid factor)
- LPG = 42 kg per 14.2 kg cylinder
- Car = 0.17 kg per km
- Flights = about 90 kg per flight hour
Worked example
These are the sample values already filled in the calculator above, and the result it returns for them:
| Input | Sample value |
|---|---|
| People in the Household | 3 |
| Household Electricity (kWh a month) | 250 |
| LPG Cylinders a Year (14.2 kg) | 8 |
| Your Car Travel (km a month) | 500 |
| Your Two-wheeler Travel (km a month) | 150 |
| Bus / Metro / Train (km a month) | 200 |
| Flight Hours a Year | 4 |
| Your Diet | Non-vegetarian (chicken, fish) |
| Result | Value |
|---|---|
| Your Annual Carbon Footprint | 3.37 tonnes CO₂e |
| Per month | 281 kg CO₂e |
| Largest source | Car |
| Compared with the Indian average (about 2 t) | 169% |
| Compared with the world average (about 4.7 t) | 72% |
| Trees to absorb it (21 kg a tree a year) | 161 |
Tips for using the Carbon Footprint Calculator
- Switching to LED lights and 5-star appliances cuts electricity emissions quickly.
- One return flight can equal months of daily commuting – take trains for shorter trips.
