Horizon 2030 for Banking: The Audited Green Ledger – Sustainability, with Julio Guijarro
By Ali Paterson · 13 October 2026

Quick Summary
In this episode of Horizon 2030 for Banking from Red Hat, Julio Guijarro, EMEA Field CTO, discusses sustainability in IT: why it depends on data about energy consumption, the Kepler project, and the effect of transparency on behaviour.
Why Does He Start With Data?
Julio notes that sustainability has been discussed for a long time. For any green agenda, he says, organisations need data to understand what is affecting and consuming energy, which he describes as becoming more precious than ever, and how that consumption relates to the way IT is used. He adds that AI, while a fantastic technology, makes very intense use of energy.
What Is Kepler?
He explains that Red Hat began work several years ago on technology, called Kepler, that uses AI and machine learning techniques to pinpoint how compute processes consume energy. Working with customers, he says the benefit goes beyond tracking cost:
- It helps organisations understand where energy is being over-used and optimise it.
- When consumption is exposed to users and developers, it changes their behaviour.
What Is His Conclusion?
Without data, he says, people cannot see how their work affects consumption and it is difficult to change. His answer is to start exposing where the energy goes across IT systems and processes. Once the impact is understood, he expects technical people to work on efficiency, but he stresses the change is not only technological: the behaviour of the people using the technology has to change as well.
