Your plane travel destroys polar bear habitat

A group of polar bear researchers wants you to do more than worry about the fate of these beautiful animals. They’ve calculated how much summer sea ice is melted per metric tonne of CO2 emissions. Then you can decide if the flight you’re planning to take is worth destroying polar bear habitat.

How much microplastic is there in your laundry basket?

Every time you wash clothes, you are releasing microplastics into the sea, but we know little about the amount and distribution of such material from different types of textile. Research scientists are now working on measuring and capturing microplastics in our laundry.

SF6: The Truths and Myths of this Greenhouse Gas

The atmospheric concentration of the highly-potent greenhouse gas SF6 has never been higher. Fingers have been pointed at the expanding renewables industry, but is that a fair assessment?

When art turns climate activist

Can art that literally takes your breath away make you more climate friendly? You can find out yourself if you happen to be in Madrid, at the UN Climate Change Conference, COP 25.

Lithium can now be recycled

Lithium from Norwegian electric car batteries isn’t recycled that often. Instead, it ends up as waste when other metals it’s mixed with are recycled. But this may change.

Testing CO2 transport on the laboratory roof

When scientists carry out experiments to investigate safe and efficient CO2 transport on the roof of the thermal power engineering laboratories at Trondheim, Norway, the noise they make will sound like a jet engine.

Svalbard reindeer populations rebounding from centuries of hunting

As reindeer go, the animals living on Svalbard might not be Santa’s first choice. They’re a smaller subspecies of their common mainland relatives, and to save energy they basically never run. But because they were nearly exterminated from Svalbard around 1900 — and were then protected in 1925 — the animals provide unique insights into how conservation can help species thrive.

Computer video simulation can limit flooding

Floods are expensive and at times dangerous. But what if a computer disaster simulation game could show politicians and local people what potential floods in their town would look like?

More hydropower and a better environment

The Norwegian public authorities’ estimates of the potential to expand the country’s power plants are probably too low. A new approach is creating opportunities for increased production while also enhancing environmental aspects.

Buy less, be happier and build a healthy planet

You may feel like you can’t do anything to stop climate change. But climate activists who joined in grassroots movements managed to cut their carbon footprints and were still happier than their non-activist peers, new research shows.

Turning waste heat into hydrogen fuel

Hydrogen as an energy carrier can help us move away from fossil fuels, but only if it is created efficiently. One way to improve efficiency is to use waste heat that’s left over from other industrial processes.

Tracing the journey of microplastics in the Arctic

By now it’s well established that microplastics are a problem in the environment, even in the remotest parts of the planet. But where do different microplastics come from and how they get there, especially in the Arctic?

Your life depends on these rare raw materials

The green transition is impossible without a few relatively unknown substances. Find out more about the raw materials we cannot manage without – and why we have to act smart with them.

This is what you need to know about CCS – Carbon Capture and Storage

Why is there so much talk about storing CO2 underground? Doesn’t it cost more than it’s worth? Here we provide the research scientists’ answers and explanations of why CCS is climate technology that we are completely dependent on. And yes, this can be performed in a safe manner.

Six years into the ice — and beyond

The Arctic’s once impenetrable ice cap is melting away, with profound consequences for everything from ocean circulation patterns to fish numbers and diversity. The Nansen Legacy Project, including NTNU biologists, chemists and engineers, is working to better understand what these changes mean for the Barents Sea and the Arctic Basin
