Air travel accounts for a major share of individual greenhouse gas emissions. A transatlantic round trip adds up to 1.6 tons of carbon dioxide equivalent emission, which is the entire annual carbon budget of a person to maintain a sustainable life. However, the air travel sector is rapidly growing and has almost doubled during the last decade.

A virtual paper-making machine makes it possible to test run and optimise operations without costly downtime in the industry. New research at Karlstad University saves money and spares the environment. ”It is now possible to run the paper-making process virtually, without expensive equipment, to identify the optimal settings for each machine,” says Björn Sjöstrand, who recently submitted his doctoral thesis in chemical engineering at Karlstad University.

Ground breaking research co-authored by Avit Bhowmik published in the Proceedings of the National Academy of Sciences presents six interventions that can rapidly transform societies for climate action. Safely achieving the goals of the Paris Climate Agreement demands a worldwide radical transformation of societies to help bend the emission curve immediately and halve global emissions no later than 2030. But, this is not an easy task!

Research at Karlstad University shows that sludge and ashes as paper mill residues can be used as effective fertiliser. This involves biochar, that is, carbon from organic material returned to the forest and thus closing the cycle. "Biochar has many beneficial effects on the environment," says Maria Sandberg, senior lecturer in environment and energy systems and research leader for the project.

The anonymity network Tor, used daily by millions of users around the world, is important for people in vulnerable situations, for instance in order to avoid surveillance or control. Two Karlstad University researchers have now identified flaws in Tor’s anonymity function and contributed to technologies that make the network safer for users. The purpose of Tor is to allow users to surf the internet anonymously without information about visited webpages being registered.
