- A bus with as few as seven passengers is more fuel-efficient than the average single-occupant auto used for commuting.
- The fuel efficiency of a fully occupied bus is six times greater than that of the average single-occupant auto.
- In terms of energy consumption per passenger mile (energy used to transport one passenger one mile), transit is more energy efficient.
- Buses use 8.7% less energy per passenger mile than a typical automobile.
- Public transit moves people efficiently while producing significantly less air pollution to move one passenger one mile--compared to moving a person one mile ina single-occupant auto.
- Buses emit only 20% as much carbon monoxide per passenger mile as a single-occupant auto.
- Buses emit only 10% as many hydrocarbons per passenger mile as a single-occupant auto (hydrocarbons are VOC's--an ozone precursor).
- Buses emit only 75% as many nitrogen oxides (another ozone precursor) per passenger mile as a single-occupant auto.
Clearly, riding public transit throughout the year makes a big difference in our air quality and use of natural resources. During the summer months, when harmful ozone levels are highest, riding public transit makes an even greater difference--especially for those with health and breathing problems. Ride Transit. It All Adds Up to Cleaner Air!
