Are durable goods really that good?
Disposable products are bad. But durable goods account for two-thirds of the global household’s energy footprint.

Developing the world’s ‘hottest’ heat pump ever
Researchers working with industrial partners have developed the world’s first heat pump producing temperatures of up to 180 degrees. Such record high temperatures will enable one fifth of European industry to reduce its energy consumption by up to 70 percent, and become entirely climate neutral.
Toxic fluorocarbons – not just in ski waxes
The toxic pollutants in your ski wax basically never disappear. A Norwegian lake and the area around several Norwegian airports are full of them, and so is your body.
Researchers found an underwater landfill while looking for chemical discharges from mobiles and electronic devices
Research scientists in Norway recently set out on a scientific cruise in the Trondheim fjord to collect water samples and specimens of marine species. What they stumbled over was quite different from what they were looking for.
Green quay will provide a green fjord
Big things might be happening soon with cruise traffic in the Geiranger fjord. Smaller vessels and adapted green quay facilities could make for a green fjord and offer a solution for preserving the World Heritage site.
New technology will identify sources of plastic in the ocean
Plastic trash gets cleaned up along our beaches. But it’s also important to find out where the plastic comes from. A Norwegian app will soon be able to do this.
Capturing energy from sunlight with dyes inspired by nature
Solar cells that use special dyes to collect light could one day be integrated into buildings. Researchers at NTNU are trying to find the best dyes for the job.
London introduced car charge in city centre – and saw most harmful pollution increase
In 2003, the average traffic speed in central London was less than 14 km/h. The congestion charge improved the flow of traffic but also had unwanted effects.
The Longship that could help save the planet
Everyone knows there’s just too much carbon dioxide in the atmosphere — and we’re heating up the planet at an unprecedented pace. In the latest episode of NTNU’s new English-language podcast, 63 Degrees North, we’ll what Norwegian researchers are doing to help address this problem.
Silicon for solar cells becoming more environmentally friendly
New discoveries are making silicon production cleaner, and solar cells of the future will become even more environmentally friendly.
Shedding light — on the polar night
The polar night is dark — if you’re a person. But not if you’re a krill or a seabird or a fish. In the first episode of NTNU’s new English-language podcast, 63 Degrees North, learn how researchers discovered that there’s more than enough light in the polar night for the tiny creatures who live there.
Abandoned cropland should produce biofuels
More biofuels are needed to counteract climate change. But producing them shouldn’t diminish food production or wilderness areas. The solution may be to grow more grass on recently abandoned cropland.
Smart site selection can make hydropower greener
Even though new hydropower dam developments are intended to provide green energy, they can drown areas that are rich in plant and animal species. But this kind of collateral damage can be limited by strategic site selection, a new study shows.
Skinnier but resilient geese thriving in the high Arctic
Barnacle geese in the Arctic have been on a diet. So many now migrate to northern breeding grounds that in some places there’s less food to go around. The good news is that it doesn’t seem to restrict their population growth — yet.
Global warming is faster than evolution
If global warming happens too quickly, not all species will be able to adapt in time.
Major investment to make Norway a leader in offshore wind
NTNU and SINTEF will be partners in the newly funded FME NorthWind research centre, which will develop competitive offshore wind farms within ten years.
NTNU researcher wins ERC Consolidator Grant
The EU has awarded two million euros for research on how animals are coping with climate changes.
NTNU researchers among the world’s most highly cited
The 2020 ISI/Web of Science Highly Cited Researchers list includes seven researchers affiliated with NTNU. The list includes authors who have multiple articles ranked in the top 1 per cent by citation in their field over the last decade.
Are discarded mobile phones and electronic waste polluting our seas?
The Norwegian research organisation SINTEF will investigate whether rare earth element minerals contribute to pollution in costal areas. Research scientists from Norway, Denmark and Germany are taking part in the project.
Using materials efficiently can substantially cut greenhouse gas emissions
Emissions from the production of materials like metals, minerals, woods and plastics more than doubled in 1995 – 2015, accounting for almost one-quarter of all greenhouse gas (GHG) emissions worldwide. Material efficiency needs to play a larger role in climate planning, a new report says.
CCS during waste incineration removes CO2 from the atmosphere
The capture and storage of CO2, also known as CCS, from our waste is essential because this refuse is responsible for a large proportion or our cities’ greenhouse gas emissions. Moreover, the technology represents a relatively inexpensive abatement cost.
Species more likely to die out with rapid climate change
The great tit and other birds can adapt to changes in their food supply as a result of climate change, but they run into trouble if the changes happen too quickly.
Losing ground in biodiversity hotspots worldwide
Agriculture is eating into areas that are important in protecting some of the most biologically diverse places on the planet. Most of this new agricultural land is being used to grow cattle feed.
Water fleas on “happy pills” have more offspring
Dopamine can trigger feelings of happiness in humans. Water fleas that are exposed to dopamine-regulating substances apparently gain several advantages.
