Norway’s waste policy falls short of its goals because of inaccurate measurement methods, unreliable data and a lack of transparency about where Norwegian waste ends up, researchers say.
Imagine if everyone were to agree to do everything they can to help the planet. Right now. What sort of state would we and the planet be in in 2050? And what would we have to do?
Plastic, and plastic pollution, are a huge problem for both human health and the environment. An interdisciplinary panel of experts suggests that politicians take three concrete steps to better understand and rein in this growing problem.
Here’s how Norway can limit the loss of an all-important substance, phosphorus.
Norway’s coastline is littered with plastics from around the world. Plastic pollution is a global problem, but Norway can be a role model in putting an end to it.
A lot of research has been done to try to come up with ways of cooking food using solar energy, but what works best in practice in sub-Saharan Africa?
A new study that looked at nearly 40 million flights in 2019 was able to calculate the greenhouse gas emissions from air travel for nearly every country on the planet. At 911 million tonnes, the total emissions from aviation are 50 per cent higher the 604 million tonnes reported to the United Nations for that year.
High metal prices can drive up the costs of electric car batteries, which will reduce their adoption. Car manufacturers are already responding to this by shifting to different technologies.
Shooting sound waves through water can remove dissolved gas that results from hydropower production in rivers. This gas can harm fish. Researchers are now ready to test techniques to reduce the risk in real hydropower plants.
Europe is well on its way to achieving its ambitious climate goals of a 55 per cent reduction in emissions in 2030 and “net zero” in 2050. But proposed policies must be implemented quickly and effectively.
Norway will reap major environmental benefits if residents stop sending wearable clothes out of the country, according to a recent study on clothing consumption in Norwegian households.
Four of the six Gulf States are among the top five biggest greenhouse gas emitters per capita. Why? Oil is the answer, but not quite in the way you might think.
What should power the future’s shipping fleets? How can we change the way we build buildings so that they’re truly climate neutral? If we’re going to actively alter the planet’s climate, how should we study this?
How can we decarbonize large-scale power generation and aviation as quickly as possible? The European Research Council has awarded a substantial grant to a team of researchers who will explore this.
To limit global warming to 1.5 degrees, the EU’s Science Advisory Board on Climate Change recommends that Europe reduce its greenhouse gas emissions by 90-95% by 2040 compared to 1990. Fossil fuels should be phased out as quickly as possible.
Nineteenth-century Norwegian technology helped bring large whale populations to the brink of extinction. Can 21st-century technology help save them?
A new study provides the most detailed dataset yet on the biodiversity footprint of food. The results can lead to more sustainable diets.
Fossil fuel vehicles gulp down petrol, and electric cars gobble up minerals. The battery industry is so ravenous for lithium as a raw material that researchers believe the demand could threaten climate goals.
Climate researchers have long known that large animals, like moose, could play a role in how much the Earth will warm due to climate change. But the question is, how much? New research shows the answer can be a lot.
NTNU has tested a system to predict the heating needs on the Gløshaugen campus. The results show that we can save even more where surplus heat is already in use.
Can Europe use the energy crisis to help accelerate its efforts to achieve net zero greenhouse gas emissions by 2050? The EU’s Scientific Advisory Board on Climate Change says yes.
Cattle farming has often been portrayed as having the most detrimental environmental impact because it takes the most grazing land, uses a lot of water and has large methane emissions. But it’s not the worst. And is locally produced food always best for the environment?
Norwegian greenhouse gas emissions from air traffic are more than twice as high as the worldwide average.
How scientists and engineers across the globe — and at NTNU — are harnessing unlikely materials to cut greenhouse gas emissions.
