IT Sustainability and Financial Management – Making IT Future-Proof

We live in a time when sustainability is no longer an option, but an incontrovertible imperative for companies. Today, environmental responsibility shapes the decisions of board members and CIOs as well as those of customers and investors. It is no longer enough to see IT only as a tool for increasing efficiency or reducing costs – the real challenge and opportunity lies in understanding it as the key to sustainable transformation.

IT departments are at a turning point: their decisions not only influence the technological future of companies, but also their ecological footprint and long-term competitiveness. Transformation does not mean making small changes or gradually improving the status quo. Transformation means radically challenging existing mindsets and making IT a strategic driver that combines sustainability and cost optimisation. This transformation is not just a necessity – it is a clear competitive advantage for those who have the courage to use IT as a driver for a sustainable future. Sustainable IT is not a distant goal, but the key to long-term success in a world where environmental responsibility is becoming the central benchmark.

IT departments at a crossroads: Sustainability as a driver

IT departments play a central role in corporate strategy. Their decisions have a direct impact on a company's ecological footprint and competitiveness. However, a real transformation requires more than minor adjustments – it requires a radical rethink. Instead of seeing IT only as a tool for process optimisation and cost efficiency, companies need to recognise that it plays a key role in the pursuit of sustainability. With resource-efficient, scalable and cost-effective IT, companies can not only achieve environmental goals but also secure competitive advantages.

Incremental improvements are no longer enough. IT must act as a driver of transformation while also being anchored as a central pillar of a more sustainable corporate strategy. This requires not only technological innovation but also organisational rethinking.

The great potential of sustainably designed IT

Radically sustainable IT not only brings about isolated improvements, but also has the potential to redefine corporate strategies. The added value of such IT goes far beyond saving energy or reducing hardware costs. Here are some of the most important levers:

• Drastically reduce electricity costs: With energy-efficient technologies and intelligent energy consumption, not only can small savings be realised, but large portions of the IT budget can be reinvested.
• Sustainable hardware use: Virtualisation and cloud computing dramatically extend the lifespan of hardware. This not only reduces costs, but also avoids massive amounts of electronic waste.
• Optimise cloud costs and reduce environmental impact: Rightsizing and smart scaling mechanisms not only save money, but also make a significant contribution to reducing CO₂ emissions.
• Avoid CO₂ certificates: A significant reduction in CO₂ emissions not only means that companies are achieving their sustainability goals, but also that they are saving on the high costs of CO₂ certificates in the long term.
• Drive resilience and innovation: Sustainable IT not only strengthens the resilience of the IT infrastructure, but also paves the way for innovative, future-oriented technologies.
• Increase sales and profits: Sustainability is not just an ethical concern – it is increasingly becoming a selling point. Companies that pursue a green IT strategy not only improve their profit margins, but also create a positive brand image.
• Meeting external requirements: Whether it's compliance with the Energy Efficiency Act, contributing to CSRD, meeting capital market requirements in ESG ratings, or investor demands. A more sustainable IT and thus optimised environmental indicators help to achieve these goals.

More than just numbers: IT Financial Management as a transformation engine

When we talk about IT costs, it's not just about managing budgets. Financial management in IT must be a strategic tool that activates major levers and enables innovation. It's not enough just to create reports – the financial metrics must be used in a targeted way to make IT a real value driver in the company. And it's not just about efficiency gains, but about investing every euro in such a way that it has maximum impact – for the company and the environment. Only targeted resource management – whether financial or ecological – can free up new resources for innovation. These must be allocated in a targeted manner to optimally support business and sustainability goals.

Transformative measures for future-proof IT

To strategically optimise IT costs and sustainability, measures are needed that go beyond mere improvements. Here are some key approaches that enable a far-reaching transformation:

• 1. Rightsizing with a big impact: Resources must be precisely aligned with demand in order to drastically reduce both costs and CO₂ emissions. This leads to a highly scalable and efficient IT landscape.
• 2. Strategic workload placement: Placing workloads where renewable energies can be used not only reduces energy consumption but also actively promotes the decarbonisation of IT.
• 3. Intelligent workload scheduling: Executing workloads when energy availability is at its most sustainable – such as when solar or wind energy is widely available.
• 4. Dynamic scaling: Adjusting resources in real time to current demand. This enables optimal use of IT resources and prevents energy waste.
• 5. Targeted instance selection: The right choice of IT instances reduces operating costs and significantly minimises the ecological footprint.

These measures show that companies can radically transform their IT and maximise efficiency and sustainability at the same time. It's not about taking small steps – it's about making bold decisions and leading IT into a green and economically successful future.

What we do at adesso – Transformative consulting for IT decision-makers

In our work at the CIO Advisory Competence Center at adesso, we start right here: we support companies on their way to sustainable and cost-optimised IT – not with small optimisations, but with a far-reaching and holistic approach. Our range of services includes:

• Strategy consulting for transformation: We develop customised roadmaps that help companies to radically redesign their IT – and to achieve both ecological and financial goals in the process.
• Control and monitoring: With innovative KPIs and reporting systems, we create the basis for IT that proactively manages both financial and sustainability goals.
• Organisational consulting: We help create the right structures, roles and responsibilities needed for a long-term transformative IT strategy.
• Business process consulting: From optimising existing processes to developing completely new approaches, we help companies take their IT to a new level.

Implementation support: We don't just provide support at the consulting level – we actively help with operational implementation, from supplier management to technical implementation.

Now is the time for big decisions

The question is not whether you should start an IT transformation, but how. The first step is to create a common understanding and to find initial approaches for making IT more sustainable and cost-efficient. Those seeking support or wanting to get started on the topic will benefit from a clear roadmap. Here, experienced partners can help define the first steps and identify quick wins. This results in a roadmap that effectively combines sustainable IT and cost optimisation – and future-proofs companies.
