"Well, when something is carbon-neutral, it means that the activity has no net greenhouse gas emissions. So, for instance, you might offset the fuel that you use by using renewable energy or even by planting trees to offset your emissions. In practice, there are different levels of being carbon-neutral. When you hop in your car, do you count just the gasoline that you use? Or do you include the fossil fuels that went into making the car or building the roads you drive on? Most people just think about the fuel used."
"The term carbon footprint, it's come to mean just the amount of carbon dioxide and other greenhouse gases that come from a given activity, such as driving your car, again.
