New climate-proof solutions for hard surfaces

High-density road infrastructure that emphasise maximum durability and minimum maintenance create inflexible systems, which put increased stress on urban trees and lead to increased risk for flooding. Over the past five years, the ‘Climate-proof solutions for urban surfaces’ project...

Environmental impacts of Plug-in Hybrid Vehicles in Nordic traffic conditions

Plug-in Hybrid Vehicles provide substantial environmental advantages compared with comparable Internal Combustion Engine Vehicles. Two Plug-in Hybrid Vehicles energy consumption, CO2-emission and locally polluting emissions were tested in VTT’s emission laboratory in Finland, at +23°C and...

How can high levels of particles in tunnels be reduced?

Traffic jam in a road tunnel.
A new study from the National Road and Transport Research Institute (VTI) demonstrates that older types of trains produce more particulate emissions in railroad tunnels than do newer ones. Dust binding, improved paving, and reduced studded tyre use could reduce coarse particle levels in road...

Nordic capitals are prioritising pedestrians

Street with people in Stockholm
Helsinki, Stockholm and Copenhagen are all working strategically with pedestrian prioritising and urban life. Car free city centres are high on the political agenda in many Nordic cities and in a range of European countries. New policy measures are applied and in many cases, significant...

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...
