Other experts are critical of this method. New analysis method aims to solve climate puzzle Researchers have developed a method for analysing 1.5 million-year-old ice. The analysis – which goes back almost twice as far as previously analysed ice cores – should help solve a climate puzzle. Recipe for greener concrete 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. Improved carbon footprint thanks to the utilization of surplus electricity Power-to-X processes could play a key role in reducing Switzerland’s CO₂ emissions. These processes convert excess electricity generated using renewable sources into liquid or gaseous energy carriers. A group of researchers recently explored the potential of power-to-X for Switzerland. Green Steel Revolution 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. 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.
