We’re committed to reducing our environmental impact in everything we do
From the energy powering our data centers to the hardware running your services, here’s how we’re making it happen.
Renewable since day one
Our own data centers have run on 100% renewable electricity for many years. For us, clean energy has always been fundamental to how we operate, not a recent commitment.
98.9% recycled, reused, or recovered
In 2025, 98.9% of the 503.4 metric tons of waste generated across our data centers was recycled, reused, or recovered. 100% of our IT hardware was recycled or reused, with only a small remainder of general non-recyclable waste ending up in landfills.
Certified by experts
Our energy and environmental management systems covering 100% of our data centers are independently certified by external auditors, so our sustainability claims are verified, not just self-reported.
Sustainability that goes beyond the basics
At IONOS, your digital growth and a sustainable future go hand in hand.
Low-carbon hosting
Our data centers run on 100% renewable electricity and have for many years. Six of our nine own data centers also run on biofuels, which means 99.8% of all energy used across our infrastructure came from renewable sources in 2025.
Water efficiency
Water is a resource we take seriously. By avoiding water-intensive cooling systems, our water usage effectiveness (WUE) score sits 99% below the industry average, keeping our infrastructure future-proof.
Beyond our data centers
Our sustainability commitments extend to our offices around the world. We’re targeting 100% renewable electricity across all our offices by 2030, with 83% already achieved. We’re also transitioning our entire company fleet to electric vehicles, with 23.9% already making the switch.
Renewable energy without the grid
Three of our nine own data centers generate their own solar energy on site. In 2025, we produced 2.8 GWh of renewable electricity ourselves, enough to power about 700 European homes for a year.
Responsible waste management
We always extend our servers’ lifespan first, before reuse and recycling. In 2025, we recycled and reused 100% of all data center IT hardware waste, working with specialized green IT partners.
Other sustainable initiatives
Efficient server design
We’ve introduced compact, modular blade servers in five of our data centers worldwide. Their smaller footprint means more processing power in less space, lower cooling requirements, and simpler maintenance. Components can be replaced, upgraded, and refurbished easily, extending the life of our hardware and reducing waste in the process.
Renewable energy meets agriculture
Our solar installation at our data center in Niederlauterbach, France, is more than just a renewable energy project. In partnership with a local sheep farmer, the land is purpose-designed for dual use, generating clean energy above while providing grazing pasture below. The solar panels provide natural shade, reducing water consumption and the need for chemicals, while supporting soil quality and local biodiversity.
