Home Carbon Footprint Calculator
See the carbon footprint of your home’s electricity. Enter your monthly units (kWh) — it’s on your bill — and see the yearly CO₂ from grid power, the trees it would take to offset, and how much rooftop solar cuts it.
Your average monthly units (kWh), from your electricity bill.
Slide up to see how much on-site solar cuts your footprint.
Uses an indicative Indian grid factor of 0.71 kg CO₂/unit. The real figure (published by CEA) changes yearly and falls as the grid gets greener.
tonnes of CO₂/year from 3,600 units.
The greenest unit is the one you never use, so cut consumption first (efficient appliances, less waste), then generate with solar — the green ladder.
Indicative. This covers only your home’s grid electricity (not cooking gas, vehicles or embodied carbon), using an average grid emission factor that varies by region and year and falls over time. The tree figure is a rough offset equivalent. Use it to understand scale and the effect of cutting use and adding solar — not as an audited figure.
