WEGreen - SWForum and HUB4CLOUD Workshop on Engineering Green and Sustainable Software in the Computing Continuum


Co-located with GECON 2022, 15 September 2022, Izola, Slovenia

#WEGreenWorkshop #SWForumGECON22

Paying attention to sustainability and the environmental impact of products and processes is a normal and expected part of all activities. We have seen national and international commitments around this, for example, the EC and many national governments are making commitments to be 'NetZero’ by 2050 and in many cases before then.

Information and Communications Technology (ICT) is an area which currently has one of the largest impacts and even now produces more CO2 than the airline industry, one of the traditional high-profile emitters. This is not entirely unexpected with the pervasive nature of ICT in all parts of our professional and personal lives. As such, though, it is also an area where increases in efficiency or changes in practice could have a great impact by understanding all facets of the problem. This is especially true in the context of the new computing continuum, encompassing as it does the full range of devices and services from the personal and IoT, through the edge and into the cloud, as well as all of the networking systems between them. This is a significant challenge, as making these complex systems requires agreement among different actors who only have the visibility and possibility to operate on parts of the overall system. For this reason, specific attention is required of the research community to find methodologies, methods, and tools to achieve real sustainability of software.

This workshop will focus on all issues concerning the engineering practices relevant to the creation and execution of green and sustainable software in the cloud continuum.

Keynote speakers:

David Ekchajzer

David Ekchajzer
Co-Founder of Hubblo, Member of Boavizta


Keynote: Assessing the environmental impacts of digital technology: open source versus opacity.

Bio: For the last two years, David has been working on the development of open methods, tools, and data to measure the environmental impacts of digital technology. In the academic context, He is working with mixed methods combining social sciences and environmental assessment for a more global consideration of the environmental impacts. David is a co-founder of Hubblo where we help organizations to manage and reduce their digital impacts. He is also a member of Boavizta, an association that works to facilitate the consideration of these impacts.

Ilias Iakovidis

Ilias Iakovidis
Adviser at the European Commission, DG CONNECT


Keynote: EU measures to improve the energy and material efficiency of the ICT sector.

Bio: Dr. Iakovidis is currently an Adviser to DG Connect, coordinating the work related to Green digital transformation. In addition to work on improving the efficiency of the ICT sector, in particular datacentres, electronic communications and digital devices, he  is also working on maximising the contribution of digital solutions (networks, technologies and applications) to accelerate the transition to circular economy, and, to support the sustainability goals in sectors such as energy networks, manufacturing, transport, and agri-food.

Submission of abstract contribution is closed


The aim of this workshop is to explore the major developments in the European GreenICT ecosystem including all areas from the application to the infrastructure. The presentation of open source approaches in particularly welcomed. The topics of interest include, but are not limited to:

  • Positive environmental impacts of the ICT space for business and the society;
  • Energy consumption measurement & benchmarking
  • Algorithmic efficiency
  • Sustainability of Edge/Cloud computing application and data distribution & management
  • Energy saving/aware applications/stacks/architectures
  • Energy saving/aware system/hardware design
  • Energy-aware management of data centres
  • Energy-aware services of communications systems

Also speculations on the potential sustainability of research results being produced in projects not specifically focusing on sustainability would be welcome.

Types of submissions

The workshop format will be highly interactive, and is aimed at triggering discussion and facilitating the creation of new initiatives and research groups. We welcome vision papers and research reports in the form of short abstracts (up to 5 pages in the LNCS format).

The submissions will be assessed by the workshop Program Committee for their relevance to the workshop topics and their potential impact in the discussion.

Accepted papers will be presented during the workshop and will be published in the workshop proceedings, as part of the GECON’22 proceedings.

While we strongly encourage in-presence participation, online attendees will be admitted as well.

How to submit

Contributions will comply to the LNCS format (the templates are available at the Springer Web site on Information for LNCS Author).

All contributions must be submitted using the EasyChair platform available at this link
