When the Chinese giant awakes
When China sets its sights on a goal, the country can change at a blindingly rapid pace. Now the country is focused on innovation and technological innovations, with renewable energy at the forefront.

When the hum of insects disappears
Several countries are warning of massive insect deaths. Right now we don’t know how matters stand in Norway. But that’s about to change.
Santa Claus take note: winter is coming, but get yourself a raincoat
Climate change in the Arctic means more winter rain, and consequently more rain falling on snow. The result can be a buildup of ice under the snow, which can wreak havoc with arctic ecosystems.
Making it easier to capture CO2 in the cement industry
Cement manufacture accounts for as much as seven per cent of global greenhouse gas emissions. A new hybrid technology makes it easier and less expensive to capture and purify CO2 produced by the industry. And the technology can be retrofitted to existing plants.
Norwegian trees can power our jets
As much as 20 per cent of jet fuel burned in Norway in 2030 could be biofuel made from the country’s forest residues. This alone could cut greenhouse gas emissions from Norway’s aviation sector by 17 per cent.
Spending our carbon budgets wisely
Our carbon emissions are much higher than are needed for us to have happy, healthy lives. But cutting these emissions requires us to think differently about how we measure growth and progress.
What does sheep grazing do to the mountains?
Livestock grazing affects the landscape. What effects does it have on the vegetation?
Ecolabels alone don’t work
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.
Entrepreneurs aim to end ghostfishing
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.
Geoengineering, other technologies won’t solve climate woes
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.
Minerals and Materials for a Sustainable Future
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.
New super laboratory coming to Trondheim
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.
Coastal cruise ships with wings on the bow are on the way
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.
Norwegian researchers are developing ice-cold eco-technology
Thanks to toxin-free technology that also saves energy, Norwegians can eat their ice cream without worrying about the climate.
Clothing, furniture play a role in ocean and freshwater pollution
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.
Debatable whether Norway will become Europe’s green battery
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.
Driverless ferries to replace footbridges
Soon the prototype for the world’s first driverless electric passenger ferry will be ready to launch in Trondheim.
New filter removes run-off chemicals
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.
Envisioning a future where all the trees in Europe disappear
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.
Global trade doubles material use for fashion, electronics over two decades
A new database gives researchers — and potentially policymakers — the ability to see how global trade affects environmental impacts.
Robot vision makes solar cell manufacture more efficient
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.
New study estimates the carbon footprints of 13,000 cities
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 CO2 using heat pumps
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.
Nine things to know about microplastics
Picking up a plastic bag from the beach makes a bigger difference than you might imagine.
