A carbon footprint is a measure of the impact our daily activities and lifestyle have on the environment and, in particular, climate change. It relates to the amount of greenhouse gases produced in our day-to-day lives through burning fossil fuels for utilities, consumption, transportation, and other factors.
Each person has their own unique carbon footprint, a measure of how much CO2 a person emits per year. The average person emits 26 tons (measurement for CO2) of CO2 per year. The more electricity, gas, fuel, and natural resources you use per year, the higher your personal carbon footprint will be.
