Are there vehicles that can transport a human more efficiently and emit less CO2 than by walking with one's own feet?

Some engines can operate at higher temperatures/pressures than the human body. On the other hand, vehicles have extra weight, possibly have different drag characteristics, etc. For "normal" speeds and loads, what would be the properties of a vehicle at a crossover point equal to the efficiency of an average human?

The fuel you burn is food. I heard on the news recently that a pet dog has a carbon footprint the size of a car!
