Holiday travel can be climate smart
Flying the family to Thailand to celebrate the holidays? Maybe taking the train to Åre? The difference in climate impact is considerable, according to environmental research.

Breakthrough in the fight against “track slip”
Track slip caused by leaves on the track costs SEK 100 million annually, according to a study by the National Rail Administration. A solution to the problem, which according KTH researchers is most prevalent in the Stockholm area around late October/November, is however close to hand. The origin of this slipperiness caused by leaves falling on the tracks is unclear, and intensive research is now being conducted on how it can be most easily detected and best eradicated.

New car roof means reduced fuel consumption
A researcher at KTH has managed to reduce the weight of the car roof by 80 percent without making the roof significantly more expensive or producing inferior properties. If anything, the opposite is true, the new roof provides greater comfort and it is much easier to hear your passengers when you talk to one another. If the techniques used for the design of the roof of the car are also applied to the entire vehicle, it can reduce fuel consumption substantially.

The “sharing economy” is growing rapidly and is changing the conditions for holiday retail business and consumption in general.
