Geo Sol - Carbon Footprint

The document discusses carbon footprints, which measure the total greenhouse gas emissions caused directly and indirectly by an individual, event, organization, or producer. It notes that the USA has the highest CO2 output per capita and that CO2 emissions have increased rapidly since 1950 based on the type of energy source used. Carbon footprints vary significantly depending on the energy source, with renewable sources like solar and wind having much lower footprints than fossil fuels like coal and oil.
