The Norwegian wolf is extinct
The Norwegian wolf died out in the wild a long time ago. The wolves in Norwegian forests today are Finnish. Inbreeding is making them prone to extinction as well.

What is nature worth?
Climate change is not the greatest threat to the diversity of species on Earth. The main problem is that animal and plant habitats are disappearing.
The benefits of keeping concrete warm during transport in arctic conditions
Keeping concrete warm during transport between the mixing plant and construction site results in a better, cheaper and more eco-friendly product. A new type of concrete mixer truck can result in less wastage and better quality of this important building material.
CyborGoats find their way into Norwegian villages
Goats are smart animals. A new technology takes advantage of their intelligence — so they longer need physical fences. More than 2400 Norwegian farmers are already using the technology to herd their animals.
Another climate summit that changes almost nothing – again?
World leaders have gathered in Glasgow to discuss climate change. But the most likely outcome is that actions won’t extend beyond the talk.
The North Sea can drive the green energy transition
The Norwegian University of Science and Technology (NTNU) and SINTEF have travelled to the UN climate change conference, COP26, with three strong recommendations on how the North Sea can power the green energy transition.
New ultra-high material efficient, low-cost solar cells — using nanowires
A new method using nanowires can make solar panels much more efficient and much cheaper than today.
Map shows carbon dioxide emissions for more than 100,000 European cities
Cutting greenhouse gas emissions to meet climate goals won’t be easy, to put it mildly. But the job just got a little simpler for 34 European countries with the creation of a new interactive map that pinpoints emissions at a local level.
Glasgow climate talks and the fate of the planet
Just over two months after UN Secretary-General António Guterres described a new climate report on the state of the planet as “code red for humanity”, the nations of the world have the chance to do something about it. But will they?
A quick end to oil won’t save the climate
An abrupt halt to oil activities in the North Sea is not the solution to the climate crisis. The way forward is to establish alternatives to oil.
Moose appetite for deciduous trees counteracts warming effects
With the warming climate, forests are growing faster than before, and deciduous species are growing the fastest. Recent research illustrates just how much moose foraging limits this growth.
Is weight loss harmful to tiny top athletes?
Shorebirds burn a lot of fat during their long migrations. This can release toxic chemicals that accumulate in fat cells.
Is it too late to save the planet?
Code red for humanity, says the IPCC. Fortunately, there’s still a lot we can do, but we have no time to lose, says NTNU climate researcher Edgar Hertwich.
Provoking climate engagement
As you walk around the city, nature “pops up” in unexpected places. Like a “lung tree” – a tree that breathes. The Nature in Your Face research project wants to use art to create engagement.
Blocking the sun to control global warming
It sounds like something out of a bad science fiction movie — artificially blocking sunlight to keep global warming from overheating the Earth. Nevertheless, a small cadre of researchers is studying the option — so that if humankind ever needs to use it, it will be an informed decision.
Norway well-positioned to supply hydrogen to Europe
The UN Climate Panel wants us to stop using fossil fuels. Hydrogen is an alternative – but not without overcoming some obstacles first.
Rapid action can help prevent the worst consequences of global warming
A new report from the Intergovernmental Panel on Climate Change (IPCC) describes with unnerving detail just what can happen if nations fail to limit greenhouse gas emissions. But rapid international action will keep the worst consequences at bay, the panel said.
Recirculating off-gas contributes to carbon capture
Producing silicon results in large carbon dioxide emissions, but recirculating it can remove contaminants more efficiently.
Building with new thinking and old components
An old building at Tullinløkka in Oslo has set a new standard for reuse, consisting of components from other buildings – like concrete floor dividers from a government building. Building stock in Norway accounts for half of society’s total environmental impact. Thinking in new ways and reusing building components offers multiple gains.
Six factors that will determine the cost of offshore wind power
Large cost cuts are achievable for both floating and bottom-fixed wind farms in the future. If we do this correctly, floating wind turbines will be able to compete with bottom-fixed wind turbines by 2030.
Ammonia – the key to making long-haul shipping green
Relatively simple adaptation could make the cargo ships of the future completely green. The technology is based on the chemical compound ammonia, some extensive number crunching and one or two engine modifications.
Retrofitting dams for more renewable energy in the world
Many of the world’s dams are not used for hydropower, but a new study shows they could be easily altered to produce renewable energy. This would be the most sustainable solution for new energy production in the world, says NTNU Professor Tor Haakon Bakken.
The Gunnerus Award in Sustainability Science goes to a holistic thinker
The Gunnerus Sustainability Prize for 2021 has been awarded to Professor Jianguo (Jack) Liu at Michigan State University.
Where digitalization is a goldmine, for real
Billions could be saved and earned by digitalizing the mining and metals industry. China and Norway are working together to make it happen.
