The challenge: sustainability in IT

The IT industry is responsible for a significant share of global CO₂ emissions and consumes immense resources in the process. Software was responsible for up to 3% of global energy consumption in 2021 and, according to a Bitkom study, will rise to up to 23% by 2030. Climate change makes it clear that sustainable IT solutions are not a “nice-to-have”, but a necessity.

This is precisely where Green IT comes in: with a combination of innovative technology and a holistic approach, companies can reduce their ecological footprint without necessarily sacrificing performance. A study by the German Environment Agency shows that up to 90% of a server's energy consumption is influenced by the software.

Resource efficiency in the sense of sustainability must become as self-evident in software engineering as Agile or DevOps. Even small changes can quickly and easily implement energy-saving measures.

“Sustainability in software development goes far beyond energy savings – it starts with the mindset and extends to every phase of the software lifecycle.”Kollin Freise, Green IT Community

Three pillars of green software development

The Green Software Foundation has identified the following three pillars for green software: energy efficiency, hardware efficiency and carbon awareness.

Energy efficiencymeans developing applications in such a way that they consume as little energy as possible.

Software should be developed in such a way that it consumes as little energy as possible. Since energy production is often CO₂-intensive, it is worth making every effort to save and take a look at consumption.

Hardware efficiencymeans that devices such as laptops, computers and servers should be used for as long as possible.

Hardware efficiency means that devices such as laptops, computers and servers should be used for as long as possible. Moving applications to the cloud helps to optimize the use of existing hardware and reduce the need for hardware. The cloud is the Car Sharing of the IT industry.

Carbon Awarenessbelieves that applications should be run where the share of green energy is highest.

Software processes and applications with high power consumption should be run when the share of green energy is high – e.g. when the sun is shining or the wind is blowing strongly. APIs like the one from Energy-Charts (see image) help us to predict the share of green energy and then run tasks.

At Accso, we focus primarily on the first point, energy efficiency. As a custom software developer, we see this as the biggest lever for making a positive impact on CO₂ reduction.

We can only improve what can be measured.” – Kristine Schaal, Green IT Community

That is why our approach is to test and actively use measuring instruments. Carbon awareness can also help us to execute recurring and non-time-critical tasks when green electricity is available. But we can also improve hardware efficiency by taking care to program software in such a way that a hardware upgrade is not necessary and the software remains expandable and maintainable.

With Accso to your sustainable software solution

Creating sustainable software solutions is a matter close to our hearts. That is why we make Green IT accessible and are committed to establishing sustainable IT solutions in all areas. We want to accompany our customers on their journey of digital transformation and do so in the most resource-efficient way possible. 

“The most abundant source of energy, just waiting to be tapped, is energy efficiency.”Doris Bures, former Austrian Minister of Infrastructure

What is Green IT at Accso?

For us, Green IT means more than just energy-efficient software. It is a comprehensive approach that encompasses all levels of IT:

ArchitectureRethink sustainability as a new challenge.

The basis for resource-efficient IT begins with well-thought-out software architecture and optimized development processes. Energy efficiency is increasingly becoming a central requirement that must be weighed against other criteria such as performance or scalability.

MeasuringMaking energy efficiency visible.

Energy efficiency can be measured both in operation and in development. Early measurements help to assess trends and promote energy-efficient software design. During operation, savings measures can be realistically tested and optimized.

OperationUtilize efficiency potential in ongoing operations.

The operation of software and hardware offers numerous opportunities to save energy. Resources can be shut down when they are not needed, or computing power can be flexibly adjusted to the software load.

DevelopmentAlign algorithms with energy efficiency.

Measuring systems can be used to identify energy-intensive areas of software. Targeted optimization of these areas can achieve significant energy savings with little effort. The focus here is on energy-efficient algorithms and resource-saving programming.

Cloud infrastructuresSustainability in the cloud.

Switching to cloud solutions can significantly reduce both CO₂ emissions and operating costs. By switching off unneeded resources, enormous savings are possible without sacrificing flexibility.

According to a study, up to 87% of energy could be saved by moving US corporate applications to the cloud. This saving is possible primarily due to the elimination of server operation in companies. At the time of the study, there were around 3.5 million e-mail servers in the USA, the task of which could be taken over by around 50,000 servers in the cloud. The operation and manufacture of server hardware is energy-intensive.

CertificationLabel sustainable software.

The Blue Angel for software can be used to make sustainable applications visible. We are happy to advise you and support you through the certification process in collaboration with experienced auditors.

NetworkingTogether for green IT.

Whether at green IT meetups, in trade publications, through cooperation on theses or as speakers at conferences – we share our knowledge, build expertise and promote the exchange of ideas for more sustainability in IT.

Since the end of 2024, we have been a member of the Federal Association Green Software in order to intensify networking and collaboration on the topic. We are also driving the topic of green IT at Accso in our internal Green IT Community, a community of committed colleagues.
