This year the Midsummer Eve is celebrated the 22nd of June, in Sweden. For Swedes this means that a lot of people will be travelling: to their family, to a cottage or to their friends. Most buses and trains are all fully booked since weeks.
Recently, I visited Oslo. What time the closing of the event would be was a bit uncertain and rather than booking a late ticket by air I found that the bus travel, with only one stop (picture from Uddevalla), was just a bit more than 3 hours. For me this was ideal from the city center of Oslo to the city center of Göteborg. The bus had internet connection, which was good enough for me to read my emails. I was a bit late to the bus, arriving just two minutes before departure and managed to get the second last seat.
The bus was by chance familiar to me, a Volvo 9700 on a B12M chassis, 6×2, 13.5 meters. This bus will typically have a fuel consumption of 25 liter per 100 km in this line-haul traffic. Our bus had 58 passengers (and one driver). The fuel consumption is then about 4 cc per person and 10 km (a Swedish mile), equal to a snaps in volume. The resulting carbon dioxide emission will thus for this travel be less than 12 g CO2 per person kilometer.
My family and I mostly go sailing to spend the midsummer with friends on a small island in the archipelago of Bohuslän. The traditional frog dance around the Midsummer pole and the pickled herring (Sill) for lunch are mandatory activities for all except youngsters between 12 and 15 years. Beer and Aquavit is nowadays on demand only, unless you go by bus where a snaps per Swedish mile is required.
