How Norwegian scientists and engineers harnessed the country’s wild waterfalls by developing super efficient turbines — and how advances in turbine technology being developed now may be the future in a zero-carbon world.
The Intergovernmental Panel on Climate Change (IPCC) has released its third Working Group report on how humankind can mitigate the ecosystem and societal effects of climate change. Much can be done, but the challenges remain enormous, the report confirms.
While former Prime Minister Jens Stoltenberg steered Norway according to the logic of economics, today’s politicians seem to lack a basic understanding of markets. The result is a policy that amplifies energy scarcity and drives up energy prices – without policymakers recognizing this unintended consequence.
Professor Edgar Hertwich has been named to the EU’s newly constituted European Scientific Advisory Board on Climate Change, while Professor Francesco Cherubini has been asked to serve as a Lead Author for an upcoming assessment by The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES).
NTNU Associate Professor Jason Hearst has been awarded an ERC Starting Grant from the European Research Council (ERC). He will investigate how turbulence affects the ocean’s ability to absorb CO2.
Increases in economic growth contribute to one-for-one increases in carbon emissions. Energy system decarbonization and economic productivity gains are the most effective carbon emissions mitigation mechanisms for sustainable economic development.
Cutting greenhouse gas emissions to meet climate goals won’t be easy, to put it mildly. But the job just got a little simpler for 34 European countries with the creation of a new interactive map that pinpoints emissions at a local level.
Just over two months after UN Secretary-General António Guterres described a new climate report on the state of the planet as “code red for humanity”, the nations of the world have the chance to do something about it. But will they?
It sounds like something out of a bad science fiction movie — artificially blocking sunlight to keep global warming from overheating the Earth. Nevertheless, a small cadre of researchers is studying the option — so that if humankind ever needs to use it, it will be an informed decision.
A new report from the Intergovernmental Panel on Climate Change (IPCC) describes with unnerving detail just what can happen if nations fail to limit greenhouse gas emissions. But rapid international action will keep the worst consequences at bay, the panel said.
Relatively simple adaptation could make the cargo ships of the future completely green. The technology is based on the chemical compound ammonia, some extensive number crunching and one or two engine modifications.
Researchers have studied the energy consumption of 140 hotels in Norway and Sweden. The use of CO2 heat pumps could cut energy consumption in these hotels by about 60 per cent.
Disposable products are bad. But durable goods account for two-thirds of the global household’s energy footprint.
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.
Even though new hydropower dam developments are intended to provide green energy, they can drown areas that are rich in plant and animal species. But this kind of collateral damage can be limited by strategic site selection, a new study shows.
The 2020 ISI/Web of Science Highly Cited Researchers list includes seven researchers affiliated with NTNU. The list includes authors who have multiple articles ranked in the top 1 per cent by citation in their field over the last decade.
Emissions from the production of materials like metals, minerals, woods and plastics more than doubled in 1995 – 2015, accounting for almost one-quarter of all greenhouse gas (GHG) emissions worldwide. Material efficiency needs to play a larger role in climate planning, a new report says.
Agriculture is eating into areas that are important in protecting some of the most biologically diverse places on the planet. Most of this new agricultural land is being used to grow cattle feed.
NTNU researchers are playing a leading role in a new IPCC report. One way they’re helping is collecting data on a website created and operated by the university.
Governments across the globe are funding record-breaking crisis packages to cope with the economic fallout from the coronavirus pandemic. Is this the time to fund greener, more climate-friendly industries and investments?
The coronavirus outbreak raised everyone’s awareness of the significance of global supply chains to modern economies. But global supply chains also play an important role in greenhouse gas emissions. How they are managed can either increase or decrease carbon emissions, new research shows.
As nations prepare to mitigate climate change, decision makers need to understand how land use fits into the climate equation. A new study looked at land use changes over two decades and found a major shift from cropland to forests. That change made western Europe cooler.
