Sustainability a long way off for aviation

Jumbo jet in level flight high above clouds
It is hardly a secret that aviation must reduce its negative impact on the climate. This will require either less air travel or a breakthrough in sustainable aviation fuels. Emissions per flight are decreasing, thanks to more efficient engines, lighter aircraft, more seats per aircraft, and...

Trend towards fewer parking spaces

Parking space
Research demonstrates that it is possible to predict the need for parking in connection with renovations and new construction. At the same time, there is a trend towards cities, for example, eliminating street parking and instead using the land for cycling paths, as is the case in Stockholm and...

Properly Placed Vegetation in Cities Improves Air Quality

Vegetatation in city environment.
A city’s vegetation can affect its air quality both positively and negatively. The positive effect is that the total amount of air pollution decreases because the air is being filtered. On the other hand, vegetation in crowded street canyons can degrade the air locally if deployed in such a way...

Major Test: What to Think About When Choosing Winter Tyres

Motorway covered in snow
A major debate is underway as to which winter tyres are best, studded or non-studded. But there is more to making a decision as a consumer than just that question. On ice and snow, non-studded tyres made for Nordic conditions differ greatly from those produced for Central European conditions....
