NTNU researchers wanted to see if labelling products and putting up signs in stores would encourage more consumers to buy sustainable seafood. The results showed that customers bought significantly more seafood generally – including options that were not sustainably harvested.
Energy and environment
A small device, developed in Norway, will now be used in the battle against environmentally-unfriendly ghost fishing caused by lost or forgotten fishing gear.
The countries of the world still need to cut their carbon dioxide emissions to reach the Paris Agreement’s climate targets. Relying on tree planting and alternative technological solutions such as geoengineering will not make enough of a difference.
For the first time this week, the Nature Research Group, publishers of Nature, will host an international conference in Trondheim in cooperation with NTNU, SINTEF and the Geological Survey of Norway. The theme for the conference, which runs from 11-13 September, is the sustainable use of minerals and materials.
Research on minerals and materials is important in helping society make the transition to a greener economy. NTNU, the Geological Survey of Norway and SINTEF have joined forces to establish a national laboratory to that end.
Ships with wings? Researchers are piloting this NTNU-spawned technology on new coastal cruise ships now being tested in Trondheim. The wings – or foils – use less fuel and make the journey more comfortable for passengers.
Thanks to toxin-free technology that also saves energy, Norwegians can eat their ice cream without worrying about the climate.
Lakes choked with algae and marine “dead zones” result from too many nutrients in the water. The traditional culprit is agriculture, which relies on fertilizer to boost plant growth. But the production of consumer goods, like clothing, is also a major — and growing — contributor.
Can Norwegian hydropower and natural gas play a role in Europe’s future power market? Results of a recent study show that Europe needs to craft a new and shared vision for energy policy for Norway to be a player.
Soon the prototype for the world’s first driverless electric passenger ferry will be ready to launch in Trondheim.
The filter will first be used to recover aircraft de-icing chemicals. In the future it will also be used in urban areas to remove environmental toxins, pollution and probably microplastics.
Global climate change is already affecting the globe, as demonstrated by the shrinking polar ice cap, melting glaciers and cities in the grips of longer, more intense heat waves. Now a team of researchers has conducted a radical thought experiment on how extreme land use changes could influence future climate.
A new database gives researchers — and potentially policymakers — the ability to see how global trade affects environmental impacts.
In order to maintain the leading position of Norwegian solar cell manufacture on the global stage, we need sensors that can see what humans can’t.
Many see cities as the new front lines of the climate change fight. Identifying the mayors and city councils in cities with the biggest carbon footprints, and the most power to make big changes, could mobilize a wave of reinforcements.
Capturing the greenhouse gas CO2 from industrial processes such as cement manufacture is a demanding and therefore expensive exercise. However, by introducing a renewable powered heat pump in the capture system, the energy required to capture CO2 is reduced by three quarters.
Research scientists have been gazing into their crystal balls. These are the technological trends that will affect the transport systems of the future.
When China wants to exploit its hydropower resources, they can ask Norwegian researchers for advice. It is now possible for hydropower companies in China to read the handbook for environmental design of regulated rivers in their own language.
Almost all research on plastic contamination in water systems focuses on oceans. But the biggest problem is plastic that ends up in freshwater ecosystems, according to an NTNU biologist.
Norwegian research scientists are contributing to the development of the world’s hottest geothermal well in a non-volcanic area. The goal is to exploit the inexhaustible supply of heat from the interior of the Earth, and this calls for equipment that can withstand the most extreme conditions.
Many people have tried to find ways of preventing hurricanes before they make landfall, resulting in the loss of human lives. Norwegian researchers believe that the answer lies in cold bubbles.
