About this calculator
The home carbon footprint calculator per month is a simple and practical tool to estimate the amount of carbon dioxide (CO₂) emitted monthly by a residence. It takes into account electricity consumption in kWh and gas consumption, providing an approximate estimate of the generated carbon footprint.
The used formula is based on standard emission factors: for electricity, an emission of approximately 0.1 kg CO₂ per kWh consumed is considered, while for gas, the emission is about 2 kg CO₂ per unit consumed. These values may vary depending on the source and efficiency of the energy generation system.
It's essential to use this calculator to get an idea of your carbon footprint and make informed decisions on how to reduce your environmental impact. Reducing energy consumption and choosing cleaner sources are crucial steps to decrease CO₂ emissions.
When using this tool, keep in mind that the obtained values are an estimate. For a more accurate measurement, it would be necessary to consider other factors, such as the type of fuel used for heating and the efficiency of electrical appliances.
