Climate change in Greenland could cause trouble for arctic char
Greenland’s glaciers are melting and the surrounding seawater is getting warmer. How are arctic char coping with climate change? Scientists are in the process of figuring it out.

Why we need biofuels
Necessary reductions in greenhouse gases will be achieved too late if we have to wait for all our aircraft, ships and trains to transition from fossil fuels. This is why we need biofuels – in spite of the criticisms levelled at their use in a recent article published on the opinions website ‘NRK Ytring’. Biofuels are no ‘climate change mitigation ruse’, as these authors would have you believe.
Nuclear power causes least damage to the environment
A comprehensive analysis of 870 power plants worldwide shows that nuclear power is a clear winner in protecting ecosystems. Bioenergy is a sure loser.
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.
This technology replaces coal power with wood power
The Norwegian company Arbaflame is intent on persuading the world to abandon polluting coal power. The new technology makes it possible to replace coal with eco-friendly wood pellets.
Fewer cows, more trees and bioenergy
Combatting global warming will require major changes in land use, a new climate change report says. One important change could be decreasing the amount of land used to produce livestock — which means that people would have to eat less meat.
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.
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.
Your wood stove affects the climate more than you think
Fortunately, a new study indicates that heating with wood has a cooling effect.
This ingenious approach not only binds CO2, but also improves the soil
If 4,000 Norwegian farms and nurseries produced biochar and mixed it with the soil, we could halve CO2 emissions from the agricultural sector. This entirely natural approach also produces more robust and healthy plants.
True hygge with environmentally friendly log fire
A crackling log fire is pure HYGGE. But what’s actually the best way to have log fires in our modern, well-sealed and fully-insulated homes?
Food waste recycling not always the best idea
With Norway as a case study, a first-ever effort to quantify the benefits of recycling food waste versus preventing it shows prevention is the best policy. But Norway continues to invest significant funds in biogas facilities for food waste recycling.
ABC — anything but coal
Policymakers, industry and government officials will have to invest US $2.5 trillion for electricity generation over the next 20 years. A new report presents the environmental costs and benefits linked to different renewable energy sources, and makes one thing abundantly clear: anything is better than coal.
Timing is everything for renewable energy use
There’s no time to waste in shifting to renewable energy sources if we are to avoid dangerous climate change. That’s especially true when it comes to bioenergy, which causes a temporary increase in CO2 levels that is later removed as replacement biostocks grow.
A Third Industrial Revolution for Norway
Norway’s wealth and prosperity over the last four decades has been built on oil, but Jeremy Rifkin, a futurist and social and economic thinker, says it’s time for the country to change. The Third Industrial Revolution is coming, and Norway needs to abandon fossil fuels and move towards a greener future that relies on renewable energy, shared transport and ultra-efficient housing.
Low-carbon electricity future is clean and feasible
The countries of the world wrapped up preliminary climate talks in Lima, Peru this weekend with an agreement on how the UN’s 194 countries will tackle climate change. The agreement comes in advance of major negotiations scheduled for Paris next year to designed to curb the world’s production of greenhouse gases. In a publication from earlier this year, researchers at NTNU’s Industrial Ecology Programme report that the low-carbon future that would result from curbing greenhouse gas emissions is both feasible from a practical standpoint, and will also substantially reduce air pollution.
Turning humble seaweed to biofuel
A Norwegian research group has been able to achieve bio-oil yields of 79% from a common kelp. Other researchers working with the same species have yields closer to 20%. The secret is to heat the kelp very quickly and bring it to the right temperature within seconds.
Hope for the climate, hope for clean air
Climate talks in New York this week have offered a glimmer of hope that the world’s political leaders finally understand the need to act to curb global warming. An NTNU researcher says that these actions will have a beneficial side effect: cleaner air in some of the most polluted places on the planet.
Lopwood and brushwood make high-grade charcoal
When the forestry machines have finished extracting timber, what is left are tops and branches – waste which cannot be used. However, according to researchers, it is possible to turn these heaps of lopwood into high-quality charcoal.
From wood chips to alcohol in hours
New approach makes biofuel from wood faster, more economical.
