What is your carbon footprint? Is that something you ever thought about? Wondering what that means? In its simplest terms, a carbon footprint means the amount of greenhouse gases produced by a particular human activity (CSS University of Michigan, 2020). These activities can mean anything that you do while home, in school, at the office, outdoors and more. Even in your sleep, you produce a carbon footprint. According to the EPA, many of our daily activities cause emissions of greenhouse gases (EPA, 2021), which contributes to our carbon footprint.
