Using rail freight to reduce CO2 emissions
A year or two ago I set a hypothetical assignment for some of my students on a comparison of CO2 emissions on road freight versus rail freight. I based on the assumption that a CO2 charge would have to be paid by firms, and they could in fact save money by using rail freight. Of course the problem with rail freight is that is does not go door-to-door, but it might still be an option for transporting between cities or depots – depending on volume. At the time when I set the assignment, I did not find many examples (at least in the UK/Ireland), but I came across a Tesco press release in November last. According to the release, Tesco are expanding their use of rail services, which will mean 24,000 tons less CO2 and 72,000 less road journeys. Yes, this is a great thing for the environment, but the management accountant in me really wants to know the cost savings generated by this.
