CFC Introduction

Many of our daily activities - such as using electricity, driving a car, or disposing of waste - cause greenhouse gas emissions. Together these emissions make up a household's carbon footprint.

Our carbon calculator is simple, fast and easy to use — and it will deliver your total estimated personal carbon emissions about as accurately as many hours of data gathering and fact finding.

As with any online carbon calculator, ours includes some margin of error due to the difficulty and imprecision inherent in measuring the carbon dioxide (CO2) output of your morning commute or your dietary decisions, for example. Therefore, we combine the best available data and a range of informed assumptions to form the basis of our calculations and to provide you an emissions estimate you can rely on — and begin to neutralize.

Because this is a personal carbon calculator, it does not account for emissions related to commercial or industrial energy or transportation. Our focus is on those everyday variables you can influence the most — namely, your residential energy, personal travel, and dietary emissions.

To avoid confusion, we express greenhouse gas (GHG) emissions figures in CO2 equivalents, where 1 metric ton of carbon = 3.67 metric tons of carbon dioxide.
