Carbon footprint

A carbon footprint is a way of measuring how much carbon (a type of pollution) you produce. To put it into an easy way to understand, it's like leaving a footprint when you walk somewhere; only instead of a footprint that can be seen, it's a footprint made up of carbon pollution. It's a way of measuring how mucheach person, company, or other entity contributes to carbon pollution in the world.
