The climate crisis makes the search for ways to store CO2 ever more urgent. Researchers have now broken down an enzyme in a bacterium that makes it possible to bind CO2 efficiently.

It would be necessary to extract CO₂ from the atmosphere on a massive scale. 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.

Computers powering self-driving cars could be a big contributor to global carbon emissions, according to MIT.

Danes cycle about 1.6 kilometres every day. If everyone cycled that much, 414 tonnes of carbon dioxide could be saved every year. That is equivalent to the UK's annual CO2 emissions.

Aircraft noise, especially during the landing approach of passenger jets, is a major burden on people and the environment. An international project with the participation of Empa enables pilots to land as quietly and with as little CO2 as possible.

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.

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.

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.

Shipping leaves a large ecological footprint: the propulsion engines are largely dependent on energy sources that produce climate-damaging CO2 when burnt. In addition to hydrogen and methanol, ammonia is also considered a more climate-friendly substitute fuel.
