DN Opinion. The Arlanda Express is the most environmentally friendly journey to the airport

Elias van Tijn desires in his letters to the editor (DN 7 January) to enterprises transporting passengers to and from the airport will be better to account for its environmental impact. This, we set up and provide the environmentally-conscious traveler to the following documentation for travel with the Arlanda Express next time.

the Decision to build The arlanda link, which was made in the early 90's. The state wanted a railroad to the airport, among other things, for environmental reasons.

the Construction in itself meant, of course, an environmental cost, and the cost was included in the decision-making basis for whether The arlanda link at all would be built. In the scenario included that the majority of operators would use the railroad, and today is operated by, inter alia, SJ, UL, SL, and the Arlanda Express.

the complexity in the calculations. To include the environmental costs of construction as well as operation and maintenance makes it tricky to get a reliable and fair comparison, for the road traffic.

What factors should they take? Road construction of course, but should also gatubelysningar with? Petrol stations and garages? Heating bills?

Our trains are run on 100% electricity labeled ”bra miljöval”. This means that the electricity will come from renewable sources such as hydro power, wind power and biofuels.

the energy ourselves, we can't other than the train company seem to drive investment in renewable energy. ”Good environmental choice” is the only label that sets tough environmental requirements on the production, which distinguishes it from standard renewable electricity.

If we only measure emissions at the tailpipe (which often car manufacturers do when they report their emissions), it would for our train at the electrified operation to be zero. In a comparison with cars and buses will then be our transport even more advantageous than the reality, which is why we choose not to report in the way of respect for the traveler.

the Emissions from our traffic comes primarily from heating of the avisningshallen during the coldest days of the year. It is, therefore, included in our accounting, as well as kontorsverksamhet, washing, lighting and more.

we, the 58,000 flights and 3.7 million passengers per year. Emissions per gram and the ease of travel and the person will then be for the airport Express:

carbon Dioxide (CO2): 14.

nitrogen Oxides (NO and NO2): 40.

So for us it is not advertising, as the submitter claims, without information. What you expect will be the train – after cycling – the eco-friendly transportation between Stockholm and Arlanda. For the traveler, it would be interesting if the airport buses and taxis also account for their numbers so that travelers can make the right choice.
