About this calculator
The Residential kWh Footprint BR calculator converts your monthly home electricity consumption into kilograms of CO₂ equivalent, using Brazil's national grid average emission factor: 0.12 kgCO₂/kWh. This value reflects the weighted average of the country's generation sources, including hydro, thermal, wind, and solar.
It works simply: enter your consumption in kWh (found on your electricity bill) and the calculator multiplies it by 0.12 to get the carbon emission. For instance, 300 kWh yields 36 kg of CO₂ per month. The result helps you understand the environmental impact of your electricity use.
Use this tool to monitor your household ecological footprint, set reduction goals, or compare with the Brazilian residential average (about 150 kWh/month, generating 18 kgCO₂). It's helpful for students, educators, and anyone interested in sustainability.
Note: the 0.12 kgCO₂/kWh factor is a national average. In regions with more thermal power plants, emissions may be higher; in areas with hydro or renewables, lower. For more precise calculations, consult your utility's specific emission factor.
Frequently asked questions
Does the result apply to any city in Brazil?
Not exactly. The 0.12 kgCO₂/kWh factor is a national average. In cities with a cleaner grid (more hydro), the actual footprint may be lower; where thermal plants dominate, higher.
What if I have solar panels at home?
If you generate your own solar energy, your grid consumption decreases or zeroes out. The calculator only considers kWh bought from the utility. For a full calculation, subtract your generation from total consumption.
How can I reduce my energy footprint?
Switch to LED bulbs, use efficient appliances (Procel A label), avoid peak hours, and consider renewable sources like solar or wind.
Why is the factor 0.12 and not some other value?
This value is published by the Ministry of Science and Technology (MCTI) as the average emission factor for Brazil's electricity grid for greenhouse gas inventories.
What is the average residential consumption in Brazil?
According to EPE, the average residential consumption is about 150 kWh/month. With the 0.12 factor, that equals 18 kgCO₂/month.
