Geography and cartography provide the spatial context needed to assess how transportation activities impact the environment. By mapping routes and distances, we can translate physical travel into quantifiable carbon emissions.
Each mode of transport—car, bus, train, airplane—has a characteristic emission factor that reflects the amount of CO₂ released per kilometer per passenger. These factors depend on fuel type, vehicle efficiency, and occupancy rates.
Combining distance data with mode‑specific emission factors yields a simple yet powerful formula for estimating the carbon footprint of a journey. This calculation supports sustainable planning and policy decisions.
EF_{mode} = emission factor for selected transport mode (kg CO₂ per km per passenger)
P = number of passengers
