13. Climate action
One possible means of limiting global warming is the use of a technology to remove carbon dioxide from the atmosphere, referred to as negative emissions. Researchers in the Division of Energy Technology have developed a combustion technology, known as “chemical-looping combustion” in which waste carbon dioxide is extracted separately rather than being mixed with air. The technology makes it cheap and easy to capture carbon dioxide instead of releasing it into the atmosphere. There are currently 34 pilot installations of chemical-looping combustion all around the world.
The food we eat accounts for a fifth of greenhouse gas emissions in Sweden and a quarter of emissions globally. Chalmers researchers study food from many different perspectives, including climate. One conclusion drawn by the research is that, in certain respects, organically grown food is worse for the climate
because larger areas of land are required.
