📘 About the Household Carbon Footprint Calculator

A carbon footprint is the greenhouse gas your activities release, measured in tonnes of CO₂-equivalent. For most Indian households the biggest parts are electricity (India's grid is mostly coal, about 0.72 kg of CO₂ per unit), vehicle fuel and food.

Enter your monthly bills and habits. The calculator uses standard emission factors to estimate your household's yearly footprint, divides it per person, compares it with averages for India (about 2 tonnes per person) and the world (about 4.7 tonnes), and shows which source is largest.

🧮 Formula

Footprint

Σ (amount used × emission factor)

Where

Electricity = 0.72 kg CO₂ per unit (Indian grid)
LPG = 2.98 kg per kg
Petrol = 2.31 kg per litre
Diesel = 2.68 kg per litre

💡 Biggest cuts

Rooftop solar can cut the electricity part to near zero.
One long-haul return flight ≈ 2 tonnes — a whole year for an average Indian.
Car-pool or use the metro for daily trips.
Set the AC at 24–26 °C.

❓ Frequently asked questions

What is the average carbon footprint in India?

About 2 tonnes of CO₂ per person a year from fossil fuels (Global Carbon Project), less than half the world average of about 4.7 tonnes and a seventh of the US figure.

What is the biggest cause of a household's carbon footprint?

In India, usually electricity — especially air conditioners — followed by petrol or diesel for vehicles and flights.

How can I reduce my carbon footprint?

Rooftop solar, efficient appliances, an EV or public transport, fewer flights and more plant-based meals make the biggest difference.
