Track: SUSTAIN_ability – Responsible Steps into the Future
- Mittwoch
08.02. - Donnerstag
09.02.
There are many discussions, slogans, and myths out there when it comes to sustainability. But what is behind all those slogans? What does “carbon neutral” really mean and how does it compare to “net-zero”? Is my cloud really running on renewable energy? What are the low-hanging fruits when it comes to reducing carbon emissions? And how does “carbon offsetting” really work?
This session explains all those slogans and concepts, sheds some light at common myths, and provides the audience with a solid understanding of the topic.
Target Audience: Architects, Developers, Managers, Project Leaders
Prerequisites: No prerequisites
Level: Basic

The topic of Green Software is very important because software is everywhere and affects the environment indirectly through the usage of hardware. Jochen Joswig explains what Green Software means and more detailed how energy demand can rise through software usage. There are different degrees of software effects on the environment that can be considered and evaluated. Jochen Joswig is furthermore researching green software metrics, approaches, quality criteria and how they can be applied in the daily business of software development.
Target Audience: Software Engineers, IT-Architects, IT-Consultants, Manager, ESG-Consultants, Sustainability Manager
Prerequisites: None
Level: Basic
Extended Abstract:
Information and communication technology (ICT) 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, in his opinion it is 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 this talk, Jochen Joswig will introduce some of the key ideas and methods from his research and make the matter of Green Software more accessible. Furthermore, he will introduce some areas in which in his 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 creating software solutions that provide added value, are satisfying to use and are eco-friendly, all at the same time. Jochen Joswig works as software engineer at MaibornWolff and is doing research in Green Information and communication technology (ICT).

Over 95 % of companies in the EU are small businesses with less than 250 employees. Many of them would like to reduce their carbon emissions but very few have the knowledge and time needed to take action.
Reaching a sizable fraction of these companies with actionable information about their carbon footprint has a huge potential for climate impact. But is that possible for an organization with less than 10 employees? While also working at a sustainable pace?
Target Audience: Everybody willing to explore how to build software for our future
Prerequisites: none
Level: Basic
Extended Abstract:
Humanity of today is faced with several very serious challenges: environmental problems such as climate change are changing our conditions for living and producing food, making social problems like poverty and global inequality worse. A good future for our Planet Earth and the humans it supports is possible, but only if we act for it. The aim of this session is to give more people the confidence and tools to get more people to do exactly that: act for a better future.
We’ll spend most of the session exploring the story of GoClimate, a company founded for the sole purpose of stopping climate change. From the example of GoClimate’s journey we’ll extract a toolbox for making an impact on a global problem with a small team. Hopefully you’ll leave this talk convinced that your actions matter and with concrete ideas on how you can act.
Since many years Pia Fåk Sunnanbo is a software engineer with experience from a wide range of languages, environments and domains. She loves deleting code and using the simplest tools possible. Fascinated how humans create technology and technology changes human behavior and lives. She holds a firm belief that software engineering knowledge is a huge power in today's society. It's our responsibility to use it for good. Works full time to stop climate change.

Java applications are widely used and often several years old. You can use these applications in the cloud via lift-and-shift (helps nothing) or you can rewrite the application in cloud-native style and use the advantages of the cloud.
An alternative for existing applications is missing here. It must be possible to go to the cloud and use advantages such as serverless and scale-to-zero WITHOUT having to rewrite the entire application.
I will show what is already working well today and where the rough edges are.
Target Audience: Architects, Developers
Prerequisites: None
Level: Basic
Additional information:
In the session, we'll move an existing application to the cloud and save over 70 % of operating and maintenance costs with serverless and scale-to-zero.

Sustainability has become a huge topic. And software is eating the world. As a consequence, we are responsible for the growing ecological impact of the solutions we create.
In this session, we will discuss several sustainability patterns, ranging from the infrastructure level over design and development to requirements and processes that support us in reducing our carbon footprint - including trade-offs and tips for implementation.
After this session you will have a little toolbox for creating greener IT systems.
Target Audience: Architect, Lead Developer, Project Lead, Manager, Decision Maker
Prerequisites: Desire to create ecological sustainable IT solutions
Level: Advanced
Extended Abstract:
Sustainability - especially reducing our carbon footprint - has become a huge topic in many areas of our lives. And as software is eating the world, we are responsible for the growing ecological impact of the solutions we create.
In this session, we will look at more and less intuitive IT sustainability patterns at various levels that can help us to reduce our carbon footprint, including trade-offs and practical tips for implementation.
After this session you will have a better understanding how you can create greener IT systems and what it means in practice.
Uwe Friedrichsen travels the IT world for many years, always in search of innovative ideas and concepts. His current focus areas are system design, resilience, sustainability and making IT a (bit) better place. Often, you can find him on conferences sharing his ideas, or as author of articles, blog posts, tweets and more.

Climate action and green software engineering has risen to the top of many technology companies' agenda. With accuracy hungry algorithms ML software is consuming more and more computational resources, largely benefiting from the increasingly better hardware. Are the results worth the environmental cost?
This talk introduces the field of green software engineering, showing options to estimate the carbon footprint and discuss ideas on how to make Machine Learning greener, giving you the tools to take an active part in the climate solution.
Target Audience: Architects, Developers, Data Scientists
Prerequisites: Basic understanding of the AI lifecycle
Level: Advanced
Extended Abstract:
AI systems have a huge carbon footprint and impact our global commitment to keep global warming to no more than 1.5°C – as called for in the Paris Agreement. To reach this goal, emissions need to be reduced by 45 % by 2030 and reach net zero by 2050. The rising interest in getting a better handle on the carbon emissions due to the AI lifecycle has garnered interest from the research and practitioner communities across industry, government, academia, and civil society.
The objective of this learning series is to break beyond surface-level discussions and dive deep into understanding the challenges and opportunities related to assessing and mitigating the carbon impacts of AI systems.
This session will also walk through the Green Software foundation's Software Carbon Intensity specification and explain why how you measure impact matters.
