Using EV tyres to counter traffic noise

Research shows that fitting tyres with very low rolling resistance, combined with the right road surfacing, can provide just as much noise reduction as traditional noise barriers.

Trondheim 08.06.2016 : The leading technical universities in the Nordic countries (Aalto, Chalmers, DTU, KTH and NTNU) celebrate their 10th anniversary of collaboration with a high level summit in Trondheim 8 June 2016. The purpose of the summit is to establish a unique networking arena for key actors in the Nordic innovation eco-systems. Photo: Thor Nielsen

Five Nordic universities look into the crystal ball

The Nordic Five Tech, an alliance of the leading technical universities in the Nordic countries, celebrated its tenth anniversary this June with a high level summit to plot a strategy for its next decade. There was talk of horses, cars, and swimming robot snakes.

Japan-Norway Arctic Science and Innovation Week

Representatives from Japanese and Norwegian universities, research institutions, government agencies and industries interested in polar issues will gather in Tokyo in early June to present research results and build partnerships.

NTNU builds bridges to Japan

Starting today, Hiroshito Matsumoto will work from a base in Toyko on behalf of NTNU and the University of Bergen to build new research partnerships between Japan and Norway.

Freezing plants to predict the fate of the Arctic

Global warming means much warmer winters in the Arctic, with more rain and icing. Researchers are working to understand what that will do to plants that have evolved to overwinter under a thick blanket of snow.

Keeping Arctic villages, infrastructure from falling into the sea

The Arctic is set to be a 21st century boomtown, as summer sea ice melts away, opening the area to increased trans-Arctic shipping and oil and gas development. A new understanding of Arctic coastal erosion offers clues to how to best protect the docks and other infrastructure this development will bring.

Hacking Trondheim to cut greenhouse gas emissions

NTNU and Norway’s technological capital—Trondheim—hosted a Climathon to give the city the tools it needs to make ambitious greenhouse gas cuts. The results might be helpful to other cities around the globe that face the same problem.

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.

Kon-Tiki2 expedition in Heyerdahl’s wake

The Kon-Tiki2 expedition aims to both reinforce and challenge Heyerdahl’s theories – and NTNU will gather unique research material from the major oceans that the expedition crosses

En viktig måte å kutte klimagassutslippene på er å fange CO2 fra skorsteinene, som disse i Hellas. Men forskerne sier vi må også sørge for kutt i CO2-utslippene fra blant annet varene vi kjøper og maten vi spiser. Foto: Thinkstock

Two tickets to Paris to talk about carbon cuts

NTNU was given only two admission tickets to the UN climate talks in Paris later this month. The tickets will be used in part by two researchers from the university’s Industrial Ecology Programme to give a workshop about carbon accounting.

A climate dictionary

Have you ever wondered what climate scientists are really saying, but find it a little embarrassing to ask anyone about the language? Here is a glossary that explains commonly used technical terms.

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.

Uncovering secrets of ice that burns

Methane hydrates can be seen as a potential energy source or as a dangerous source of methane – a greenhouse gas that is 20 times more potent than CO2. With the help of a supercomputer and an interdisciplinary team, scientists have uncovered important details about their stability if they are disturbed by human-induced or natural forces.

Awash in trash at the top of the world

Every year, an estimated 8 million metric tons of plastic waste blows, falls or flows into the world’s oceans. Earlier this autumn, participants in the annual Svalbard Course plucked up 512 kg of the stuff from just one beach in two hours.

Turning political pledges into action on climate change

Beginning on 30 November, the nations of the world will gather in Paris to discuss a new global agreement on climate change. But what will it take to transform international political will into real action to curb global warming?
