November 2020: I first met the E.ON Board—online, of course, as COVID still defined the rules at the time. I was invited to a sustainability inspiration talk, which gave me the opportunity to share my professional views on the responsibilities and opportunities of companies. At that point, I had no idea this would grow into five years of collaboration and remarkable sustainable impact.
2021: the year of strategy development
In 2021, we began more in-depth discussions with Solar Markt and E.ON Hungária Csoport on the development of the Green Cloud, while together with the strategic team we also started shaping the sustainability strategy. Stakeholder research, ESG assessment, trend analysis, interviews—everything needed for a strategy that wouldn’t just end up gathering dust on a shelf. In December, the senior leadership officially approved it during a workshop.
2022–2023: the first steps
In 2022, a memorable milestone arrived: the public announcement of the Green Cloud.
We also completed E.ON’s first Sustainability Report, which already publicly documented data and plans.
In 2023, alongside the publication of the second Sustainability Report, a new initiative was launched: the “Champions of the Earth” competition, followed by its first awards ceremony—which, I believe, became a true passion project for every jury member.
2024–2025: full realization
2024 was also a defining year. The Szihalom solar power plant began operation, supplying renewable energy to the Green Cloud. The next Sustainability Report was completed, another “Champions of the Earth” competition was launched, and—of course—followed by an awards ceremony. As a new step, sustainability was introduced into corporate thinking through a large-scale client event.
In 2025, we carried out a double materiality assessment, which formed the basis of E.ON’s fourth sustainability report, now created independently by the company. And of course, the “Champions of the Earth” program and awards continued, reaching nearly 9,000 children by that time.
And now
This year, we welcomed Zsolt Jamniczky as one of the first guests of our “Honestly About Sustainability” podcast, where he spoke candidly and realistically about both challenges and opportunities. The “Champions of the Earth” program continues, and this year it will provide a total of 100 million HUF in support to kindergartens and schools to help foster more sustainable thinking and ways of living.
The impact
Looking back on these years, the numbers speak for themselves. A few highlights:
- Scope 1–2 emissions decreased by 64% between 2019 and 2024, while Scope 3 emissions decreased by 87%
- The number of smart meters exceeded 520,000 by 2024
- The waste recycling rate reached 96.9%
- The proportion of women in leadership positions is 27%
- The gender pay gap is 2.8%, which is a significant achievement compared to the Hungarian average of 17%
- Training time per employee reached 31.4 hours per person per year, three times the strategic target of 10.3 hours
These are not our numbers. These are E.ON Hungária Csoport’s numbers. We only helped design and imagine them together, and we were there when support was needed.
Five years is not a long time in a consulting partnership because it drags on—it is long because it is the time it truly takes to build trust. Strategies can be written quickly, even just for the drawer, but we work for impact, and this collaboration is a great example of that. So when we briefly met with the four leaders to celebrate, we were not celebrating our own work. We were celebrating that what we started has now become their achievement and positive impact. That we could support this process is, for me and for us, a source of pride.
Thank you for the past five years, E.ON, and thank you for all this positive impact!
