Every day, our activities directly and indirectly result in the emission of greenhouse gases. Your “carbon footprint” refers to the amount of greenhouse gases, including carbon dioxide, that are likely produced from your lifestyle and activities. Greenhouse gases can be emitted through land clearance and the production and consumption of food, fuels, manufactured goods, materials, wood, roads, buildings, transportation, and other services. Carbon footprints are usually measured in equivalent tons of CO2.
