„ Transit analysis should include emissions

- Doug Thomas ELMIRA

To the Editor,

Julian Gavaghan’s analysis of the new “seamless” public transit system (Observer, Mar. 21/24) misses a couple of significan­t points.

The cost of fuel is not the only cost of driving a car to Toronto. The cost of maintenanc­e, insurance, and so on means that fuel makes the dollar savings you state somewhat inaccurate.

More important is the carbon dioxide cost of all of us driving cars rather than using public transit. The Corolla you use as an example probably burns about seven litres of fuel per 100 kilometres. Our Toyota Prius Hybrid averages five litres per 100 kg. The trip to Toronto, presumably Union Station, from your office on Arthur Street North, Elmira is 127 km. (Google Maps). That means the Prius would consume 6.35 litres one way. At 2.53 kg. of CO2 per litre that would be 16.35 kg. of CO2 one way to transport two people.

A full bus load, should be about 40 people, or the equivalent of 20 Prii (Toyota’s official plural) with two people in each. At 16.35 kg of CO2 per car, that amounts to replacing 327.4 kg. CO2 emitted by 20 Prii with the CO2 emitted by the bus. Assuming the bus produces even four times the CO2 per km as the Prius, that is 65.4 kg. of CO2 or 262 kg. less than transporti­ng 40 people by Prius.

Given the importance of reducing CO2 using public transit this difference would make a real contributi­on to fighting climate change.

Julian’s point about inconvenie­nce is well taken, and the single fare system is an important step to reducing that. A more seamless system with integrated buses and trains would also improve that. We Canadians are too used to convenienc­e and private indulgence­s to make a rapid change to public transit, but change we must.
