There are already ideas and pilot projects that aim to achieve this. However, in order to make a real contribution to a neutral carbon footprint, the scale would have to be increased by several orders of magnitude. Green electricity takes liquid form: pilot plant for e-fuel up and running 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. An end to flight shame Will we ever be able to fly with a clean conscience again? The good news: Technologies for zero-carbon aviation are already available today. The bad: It will take years to bring them to market. ETH researchers produce fuel from sunlight and air Researchers at the Swiss Federal Institute of Technology in Zurich (ETH) have achieved a world première: They have developed a technology that produces carbon-neutral fuels using only sunlight and air. The solar refinery is already operating under real-life conditions. Empa makes eco-cement Cement production is responsible for 9 percent of carbon emissions in Switzerland. Researchers at Empa believe that this can be changed. Even cement production methods that absorb more CO₂ than they emit are on the horizon. University of Zurich teaches drones tricks Thanks to a navigation algorithm, drones are learning to autonomously perform acrobatic maneuvers. Using simulations, the autonomous aircraft are trained to become faster, more agile, and more efficient. Are electrically driven ships viable? Maritime transport accounts for a significant portion of global CO₂ emissions. Commissioned by a shipping company, researchers at the Swiss Federal Institute of Technology in Zurich (ETH) investigated how this could be changed. They see considerable potential in electric propulsion systems and in hydrogen and ammonia-based fuels. “We need to become climate positive.” Michael Braungart is the enfant terrible of environmentalists. Be it recycling or climate neutrality – the initiator of the cradle to cradle principle takes a tough stance on conventional approaches. An interview about climate-positive products, tire abrasion, and synthetic plankton. Climate scenarios made simple Climate change is too complex for most laypersons to really understand its effects. Researchers have now launched an interactive online platform that offers easily understandable insights into the most important scenarios and models. The unrecognized pioneer 60 years ago, Theodore Maiman powered up the very first laser. At that time, however, neither industry nor research saw any practical application for the technology. The story of a major misjudgment.
