A car is more or less efficient than cycling, depending on the food, car and source of electrical power, and manufacturing CO2 production. The bicycle production emits a less CO2 than the car production, tilting the comparison at the beginning of the lifecycle of both.

The GHG emissions associated with food intake required to fuel a kilometre of walking range between 0.05 kgCO2e/km in the least economically developed countries to 0.26 kgCO2e/km in the most economically developed countries.

A Tesla model 3 according to WLTP test cycle uses

0.191 kWh / km * 0.434 kgCO2e/kWh = 0.083 kgCO2e / km
