Metal production generates considerable emissions of greenhouse gases. But the type of ore used in production can make a big difference.
UN Sustainable Development Goals: Climate Action
Ten cubic kilometres of concrete, equivalent to the volume of Mount Everest, are used in construction projects every year, resulting in huge volumes of emissions. But a new eco-friendly cement may help to reduce our global climate footprint.
New discoveries are making silicon production cleaner, and solar cells of the future will become even more environmentally friendly.
NTNU and SINTEF will be partners in the newly funded FME NorthWind research centre, which will develop competitive offshore wind farms within ten years.
The EU has awarded two million euros for research on how animals are coping with climate changes.
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.
The capture and storage of CO2, also known as CCS, from our waste is essential because this refuse is responsible for a large proportion or our cities’ greenhouse gas emissions. Moreover, the technology represents a relatively inexpensive abatement cost.
The search for the perfect solar cell is not yet over. Norwegian researchers are now adopting a new approach to the cells’ raw material, crystalline silicon, with the aim of making the electricity-generating cells even more efficient.
Tired of people claiming that the climate crisis isn’t real? You’re not the only one. This is why they are wrong.
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.
A unanimous group of research scientists are convinced that kelp may share many of the applications of soya and oil, and that they can also be used to capture CO2. Seaweeds can contribute towards climate-friendly solutions in all sorts of contexts. New know-how about seaweed farming is currently accelerating industrialisation of the sector.
Droplets and bubbles are formed nearly everywhere, from boiling our morning coffee, to complex industrial processes and even volcanic eruptions. New research from SINTEF and NTNU in Norway, improves our understanding of how these bubbles and droplets form. This could improve our ability to model climate change.
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.
Chinese authorities are investing heavily in green energy. The country has become a world leader in solar and wind power. This rapid expansion was made possible by the approach taken by authorities.
Organic solar cells are usually less effective than silicon solar cells. But there is still a market for them – and they’re beautiful and exciting.
A group of polar bear researchers wants you to do more than worry about the fate of these beautiful animals. They’ve calculated how much summer sea ice is melted per metric tonne of CO2 emissions. Then you can decide if the flight you’re planning to take is worth destroying polar bear habitat.
The atmospheric concentration of the highly-potent greenhouse gas SF6 has never been higher. Fingers have been pointed at the expanding renewables industry, but is that a fair assessment?
The world’s transportation network is constantly growing. “Green asphalt” and sustainable bus transportation will ease the environmental impact of future transport routes.
Offshore wind energy is seeing renewed wind in its sails as a major industrial opportunity for Norway. But researchers warn that economic and political players could hinder this development if they get locked into the existing industrial structures.
Humankind will need to harness carbon capture and storage technologies to help keep global warming to 2 degrees C or less. New research shows that there’s plenty of room to store captured CO2 — in offshore geologic rock formations.
Lithium from Norwegian electric car batteries isn’t recycled that often. Instead, it ends up as waste when other metals it’s mixed with are recycled. But this may change.
When scientists carry out experiments to investigate safe and efficient CO2 transport on the roof of the thermal power engineering laboratories at Trondheim, Norway, the noise they make will sound like a jet engine.
