MYTH: Use of The Rapid reduces pollution and is environmentally friendly.

FACT: The Rapid is actually increasing pollution.

According to The Rapid, its average bus only gets 4.45 miles to the gallon.1) The Rapid’s buses carry an average of only 7.3 passengers at any given time (about 90% empty, based on the Rapid’s average bus capacity of 74 people).2)

Those are the numbers that The Rapid's staff claims are accurate, but using data The Rapid reports to the federal government each year, we can calculate that The Rapid’s buses emit 0.76 pounds of carbon dioxide per passenger mile.3) As a comparison, the average SUV emits 0.56 pounds of carbon dioxide per passenger mile and the average passenger car emits 0.54 pounds of carbon dioxide per passenger mile.4)

This means that The Rapid is in no way reducing pollution. Because of The Rapid’s low capacity utilization and its buses being larger than needed, a lot of fuel is being used to move around a comparatively low number of people. The buses are so empty that they are less efficient than if SUVs were used to transport every single Rapid passenger. The Rapid’s buses are a net adder of pollution to the environment. In fact, we were shocked to calculate that The Rapid’s buses added over seven million pounds of carbon dioxide to the environment, compared to the amount that would have been emitted if every single Rapid bus passenger had been transported in an average midsized car.5) The reality is that The Rapid’s passengers produced 40% more CO2 emissions than if they had ridden or been transported in cars. The Rapid’s web site falsely claims that its services reduce carbon dioxide emissions by 50%. 6)

This result, admittedly somewhat counter-intuitive, is due to several factors. The largest factor is that The Rapid is buying bigger buses over time, yet the number of passengers filling those buses is low. A second factor is that autos are getting more efficient over time. According to data released by the US Department of Energy, transit buses have gotten 75% less energy efficient since 1970.7) Conversely, passenger autos have gotten 30% more energy efficient in the same period. The chart below demonstrates this trend.

It should be noted that the above chart actually overstates the efficiency of The Rapid’s buses. The Rapid’s buses are carrying fewer passengers than the national average, making the pollution and energy efficiency picture worse. Between 2005 and 2009, The Rapid’s average bus capacity has grown from 70 to 74.8) For some reason, despite low capacity utilization, The Rapid is scrapping older, smaller buses for even larger ones.

The Rapid has purchased five hybrid-electric buses and falsely claimed that these would double the gas mileage of a regular bus.9) However, as The Rapid now admits, these buses only get 0.68 miles per gallon more than a regular bus – all for the additional cost of at least $200,000 per bus.10) The hybrid-electric buses are still less energy efficient than SUVs.

Strangely, The Rapid claims that saving $4,000 per year in fuel costs by using these hybrid buses is worth spending more than $200,000 extra for each of these buses.11) At that rate, it would take more than 50 years for the hybrid-electric buses to break even.

You’ll also notice that a service called “Rapid Van” is referenced in the above chart. This is the Rapid’s van pool ride share service. This type of service, also known as a “jitney,” is far more successful at providing cost-effective mass transit. The Rapid Van service is dramatically better at reducing pollution than The Rapid’s fixed-route bus services, yet The Rapid only spends 0.5% of its annual budget on this service. For more information on jitneys, please see the section below titled “MYTH: Using the Rapid is the only way for many people to get to work.”

2) National Transit Database Profile of the Interurban Transit Partnership, 2009 (latest date available). Available at http://www.itpwatch.org/wp-content/uploads/2009/04/ntd-2009.pdf. Divide the number of passenger miles by the number of vehicle revenue miles to come to the total average number of passengers on The Rapid’s buses. Total capacity is derived from the National Transit Database list of The Rapid’s buses and their total capacity. NTD data is available at http://www.ntdprogram.gov/ntdprogram/data.htm.
3) See National Transit Database, 2009, Interurban Transit Partnership. Available at http://www.ntdprogram.gov/ntdprogram/data.htm. The Rapid’s fixed-route bus services utilized 1,118,084 gallons of diesel fuel and 13,320 gallons of regular fuel in 2009. Each gallon of diesel fuel emits 22.2 pounds of carbon dioxide. Each gallon of regular unleaded fuel emits 19.4 pounds of carbon dioxide (See the Environment Protection Agency web site, Emission Facts: Average Carbon Dioxide Emissions Resulting from Gasoline and Diesel Fuel, available at http://www.epa.gov/oms/climate/420f05001.htm). Thus, The Rapid’s buses emitted 25,079,872 pounds of carbon dioxide in 2009. Divide that number by the number of passenger miles reported by The Rapid, and we arrive at emission of 0.76 pounds of carbon dioxide per passenger mile.
4) U.S. Department of Energy, Transportation Energy Data Book, Edition 29 (July 2010). Available at http://cta.ornl.gov/data/index.shtml. See Tables 4.1 and 4.2 for average car and SUV miles per gallon, respectively. These tables include all cars in use, not just newer models, for a more accurate comparison. The average mpg for a car was 22.6 in 2008 (latest year available). The average mpg for all trucks and SUVs was 18.1 in 2008. See Figure 8.1 for average vehicle occupancy in 2009. The average vehicle occupancy for cars was 1.59 and 1.92 for SUVs. Multiply the number of passenger miles by the number of miles per gallon for each class of vehicle to arrive at passenger miles per gallon (example for SUVs: 18.1 x 1.92 = 34.75 passenger miles per gallon). Then divide 19.4 pounds of carbon dioxide by the number of passenger miles per gallon of each vehicle to arrive at the number of pounds of carbon dioxide emitted per passenger mile (example for SUVs: 19.4 / 34.75 = 0.56 pounds of carbon dioxide emitted per passenger mile). SUVs emit 0.56 pounds of carbon dioxide for each passenger mile and cars emit 0.54 pounds of carbon dioxide per passenger mile. These numbers are significantly lower for new vehicles. Using the Transportation Energy Data Book’s numbers in Tables 4.7 and 4.9, we calculate that an average new midsize car with an occupancy of 1.59 passengers emits 0.38 pounds of carbon dioxide per passenger mile and the average new midsize SUV at average occupancy of 1.92 emits 0.40 pounds of carbon dioxide per passenger mile. Therefore a new midsize SUV emits 47% less carbon dioxide per passenger mile than Rapid buses.
5) Comparing the number of passenger miles per gallon of the car to passenger miles per gallon of the Rapid’s buses. See footnote 4 above for the amount of CO2 emitted by The Rapid’s buses. The Rapid’s buses provided 32,891,699 passenger miles of service through its standard bus services in 2009. Divide this number by the number of passenger miles per gallon of the average car (22.6 x 1.59 = 35.93, see note 4 above. Therefore, 32,891,699 / 35.93 = 915,438). Our result is 915,438 gallons of gas that would have been used to transport all Rapid passengers if they had been transported in a car with an average of 1.59 passengers. 19.4 pounds of carbon dioxide are emitted per gallon of regular unleaded fuel (see note 3 above). Therefore, a total of 17,759,497 pounds of CO2 would have been emitted had all Rapid passengers been transported in a car at the average occupancy rate. The Rapid actually emitted 25,079,872 pounds of CO2 in 2009. Subtract the number that would have been emitted, and we arrive at 7,320,375 extra pounds of CO2 emitted by The Rapid.
