How It Works

You know that electricity usage contributes to carbon emissions, but how much? With this calculator you can find out how much carbon emissions you're producing based on your building's electricity usage. This provides you with a reference point so that, if you implement a strategy to reduce your carbon footprint, you can track your success. Distributing DC power to your DC powered devices (such as LED lights) reduces your carbon emissions for those devices by up to 40%. If you'd like to learn more about AC vs DC power, and how to distribute it, check out our blog: 5 Reasons DC Electricity Should Replace AC in Buildings.

Here's how this calculator works. A number of factors influence total carbon emissions per unit of electricity used, including the time span in months, what country you live in and, of course, the average kWh of electricity you consume each month.
Take a look at the formulas below to better understand how this calculator works.

Formulas for kWh to CO2 Carbon Emissions

Total kWh

This simply calculates your total electricity usage over the span of the number of months you'd like to consider. It does this by multiplying them together.

Monthly kWh

Number of Months

CO2 e (Kg) Total For Time Span

This formula calculates your total CO2 emissions in Kg over the course of the defined time span (in months). To do this, it multiplies relevant variables together (including carbon intensity), and divides the result by 1000 to convert from grams to kilograms. Carbon intensity, or average grams of CO2 per kWh, varies depending on country. You can find the carbon intensity of your country by reviewing the reference chart on this page. If your country isn't listed, visit this website for the full list, and click the "table" tab

A calculator that compares your building's CO2 emissions based on whether your building distributes AC or DC power to DC devices. Distributing DC power to DC devices is more efficient than distributing AC to them. This is because distributing DC power to DC devices eliminates the need for inefficient AC to DC conversions.
