3 Oct. 2015: One of the promises of the diesel UP Express rail link to the airport is that it would save greenhouse gas emissions by taking car trips off the road.
But calculations by the Clean Train Coalition show that UP Express is producing more CO2 than it’s saving at current operating levels of only 2,500 riders per day.
The Clean Train Coalition estimates UP Express trains produce 318,928 lbs of CO2 per week (see assumptions below). At the current 10% ridership levels, the trains save 240,452 lbs of CO2 per week, assuming each rider would otherwise take a private car, taxi or Uber to the airport.
At that rate, UP Express produces a net excess of 78,476 lbs per week of CO2.
UP Express would need to increase current ridership by 40% to offset the amount of CO2 produced by car trips.
