Guest lecture by Jochen Joswig from MaibornWolff (20.1.2022)

Jochen Joswig from MaibornWolff will give a talk in the elite program’s special lecture series. The title of the talk is “Green Software” and it will take place virtually as an online meeting at 4PM on January 20th 2022.


Information and communication technology is both a curse and a blessing when looking for solutions to environmental problems like the climate crisis. On the one hand, things like video calls and instant messaging reduce the need for travel and thereby reduce greenhouse gas emissions. On the other hand, the total energy consumption and natural resource demand of ICT is growing. Therefore, it is in my opinion the responsibility of everyone involved in software development to use these resources as sparingly and efficiently as possible. Ideally during all parts of a software’s lifecycle.

There has been extensive research in recent years about Green Software. In my talk, I will introduce some of the key ideas and methods from this research and make the matter of Green Software more accessible. Furthermore, I will introduce some areas in which in my opinion research is still lacking and provide a personal view on how this could be changed.


Jochen Joswig studied Computer Science at the Friedrich-Schiller-Universität Jena (B.Sc.) and Universität Hamburg (M.Sc.). Since then, he has been especially interested in developing ESG and CSR software. He sees great potential in the cloud, when it comes to creating software solutions that are satisfying to use and at the same time eco-friendly, which is why he joined MaibornWolff in 2020 as a software engineer.
