Green steel is no longer a vision of the future. The transition to more environmentally friendly production, on the other hand, is. Bernhard Rischka, Director of Corporate Technology at Swiss Steel Group, explains what it will take for the steel industry to shake off its image as a climate sinner.

Steel production is responsible for eight percent of CO2 emissions worldwide. Alternative manufacturing processes exist, but the investments are high and the road is long. Two experts provide insights.

Wind and solar electricity can now be turned into climate-neutral fuels: E-fuels have the potential to play an important role in combating climate change. Scientists in Karlsruhe, Germany, are laying a technological foundation.

More than a tonne of vegetables and lettuce, positive effects on the psyche and valuable experience in terms of time-saving operation: after a five-year test in Antarctica, the German Aerospace Center (DLR) has expressed satisfaction with its "Eden ISS" greenhouse system.

Concrete has a huge carbon footprint. Researchers at MIT in the USA have now developed a method to make its production more climate-friendly. The secret ingredient: baking powder.

Researchers have calculated the savings potential of imported greenhouse gas emissions if electric cars were used as electricity storage.

Researchers want to use chicken feathers to produce green electricity. They use the keratin in chicken feathers to replace highly toxic chemicals in fuel cells.

The leading shipping associations intend to establish an international fund with a volume of five billion US dollars to drive forward the reduction of CO2 emissions – the German Shipowners’ Association (VDR) announced.

It is possible to reduce the carbon footprint attributable to driving and housing while saving money at the same time. This has been determined by researchers from the “Bioenergy and Sustainable Technologies” (BEST) competence center in Wieselburg, Austria.

In a recent study, US scientists suggest using moon dust to combat global warming, since lunar dust shields a lot of sunlight with little mass. Other experts are critical of this method.
