Plastic trash gets cleaned up along our beaches. But it’s also important to find out where the plastic comes from. A Norwegian app will soon be able to do this.
In 2003, the average traffic speed in central London was less than 14 km/h. The congestion charge improved the flow of traffic but also had unwanted effects.
New discoveries are making silicon production cleaner, and solar cells of the future will become even more environmentally friendly.
Dopamine can trigger feelings of happiness in humans. Water fleas that are exposed to dopamine-regulating substances apparently gain several advantages.
Ten years ago, the Deepwater Horizon accident in the Gulf of Mexico killed eleven men and resulted in the largest accidental oil spill in history. Years of investigations concluded that the drilling crew missed critical warning signals that would have stopped the problem. A new analysis suggests that wasn’t the case.
If your drinking water is contaminated, you’d no doubt like to find out where the pollution comes from. Researchers are working to make this easier.
Every time you wash clothes, you are releasing microplastics into the sea, but we know little about the amount and distribution of such material from different types of textile. Research scientists are now working on measuring and capturing microplastics in our laundry.
By now it’s well established that microplastics are a problem in the environment, even in the remotest parts of the planet. But where do different microplastics come from and how they get there, especially in the Arctic?
One way to reduce flight shame may lie in a ring of flames. And in the gas that’s generated in an outhouse.
It’s springtime in much of the northern hemisphere, although spring snowstorms are still possible. When that happens, salt trucks and ploughs help make roads safe. But road salt can be bad for the environment, and can rust cars, bicycles and other metal. New research shows that salt use can be safely — and substantially — cut in certain circumstances.
Cement manufacture accounts for as much as seven per cent of global greenhouse gas emissions. A new hybrid technology makes it easier and less expensive to capture and purify CO2 produced by the industry. And the technology can be retrofitted to existing plants.
Lakes choked with algae and marine “dead zones” result from too many nutrients in the water. The traditional culprit is agriculture, which relies on fertilizer to boost plant growth. But the production of consumer goods, like clothing, is also a major — and growing — contributor.
The filter will first be used to recover aircraft de-icing chemicals. In the future it will also be used in urban areas to remove environmental toxins, pollution and probably microplastics.
Many see cities as the new front lines of the climate change fight. Identifying the mayors and city councils in cities with the biggest carbon footprints, and the most power to make big changes, could mobilize a wave of reinforcements.
Almost all research on plastic contamination in water systems focuses on oceans. But the biggest problem is plastic that ends up in freshwater ecosystems, according to an NTNU biologist.
Global warming and political decisions are opening the Arctic and its frosty seas to increased development. But what will happen if that expansion results in oil spills in the frozen ocean?
Plastic trash is a rapidly growing environmental problem. But a biodegradable and natural material could replace plastic packaging and eliminate this problem.
A new model creates global hot spot maps to illuminate how what we buy pollutes the planet and where. The idea is to help governments, industries and individuals target areas for cleanup.
Minute particles of plastic, called microplastics, are everywhere. An international research team is now about to investigate how toxic microplastics are to marine animals such as plankton, crabs and fish, and to find out if such plastics accumulate in the food chain.
Ocean dumping of munitions from WWII was common in Norway and along the European coast. Some of these bomb dumps offer a natural living laboratory where biologists can study cold-water coral reefs.
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.
