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.
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.
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.
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.
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.
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.
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?
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.
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.
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.
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.
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.
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.
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.
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.
