Innovation for an ethical digital world
Since its creation, Infomaniak has been built on a strong conviction: technological performance and social responsibility must go hand in hand.
By combining technical excellence, respect for the environment and social inclusion, we are shaping a sustainable, local and committed business model. In line with the United Nations' Sustainable Development Goals (SDGs), we integrate sustainability at every level of our business. Powered exclusively by local renewable energy, our data centers boast some of the best energy and water performance in the world. Thanks to the eco-design of our software, the extended lifespan of our servers and the absence of egress fees, we offer a cloud that is sovereign, competitive and as ecologically exemplary as possible.
Responsibility at Infomaniak also means a strong human commitment to inclusion, pay equity and work-life balance. Diversity is an asset, and each person actively contributes to change.
Transparency, sovereignty, ethical governance, support for NGOs: our activities are designed to serve the interests of our customers, support the local economy and minimise our impact on the planet.
We're not just a cloud provider. We're a company committed to creating a more ethical digital world, free from the rationale of dependency and looking towards a future that's more local and respectful of people and the planet.
Compliance with SDGs and B Corp certification
The vision behind Infomaniak's entrepreneurial project has never changed:
Democratise ethical and sovereign digital technology
Offer sustainable, competitive products at a fair price that covers development, infrastructure and R&D
Growing together in an independent, committed company
In addition to this social commitment, we also have an environmental responsibility: to minimise the impact of our activities on the planet.
This commitment is also embodied in the responsible management of our data centers, the choice of our equipment and suppliers and the eco-design of our online services, as well as in the promotion of local know-how and the creation of jobs in Geneva and Zurich.
Among the United Nations' Sustainable Development Goals (SDGs) identified to build the future of our societies, eight are priorities in relation to our activities.
Environmental strategy
At Infomaniak,
mitigating the impact of our activities on the environment is a key aspect of our corporate strategy.
Since 2007, we have been taking uncompromising action to reduce our ecological impact, focusing our efforts where they have the greatest effect, with a 360° view of our business.
Today, we set our environmental and climate targets according to the standards of the Science Based Target Initiative (SBTi). Our decarbonisation trajectory will be submitted for validation by 2030, with science-based targets to tackle the climate emergency.
Reducing our impact also involves internal action: employees are regularly made aware of climate issues in relation to their department. Since 2024, the carbon footprint of our main hosting services has also been displayed on our customers' invoices.
Data centers
Since 2013, we have completely eliminated liquid refrigerant air conditioning from our data centers, in favour of natural cooling using filtered outside air. Thanks to this approach, the company achieves an annual PUE of less than 1.1 for all data centers which, to the best of our knowledge, places us among the most energy-efficient infrastructures in the world.
In 2024, we continued construction and operational testing of a new data center designed to convert 100% of the electricity consumed into heat. Located underground in an eco-neighbourhood, it will have no impact on the landscape and will heat 6’000 households in winter. In summer, 20’000 people will be able to take a daily 5- minute shower thanks to the reclaimed heat. It will also be the only data center in the world to house a cluster of AI supercomputers, which will recover 100% of its waste heat.
Our ambition in the long term is to recover 100% of the heat emitted by all our data centers. This implies designing new sites capable of exploiting the energy consumed to the full (firstly for computing and storage, and secondly to heat homes or public infrastructures) and adapting or gradually closing existing facilities that do not allow this dual use.
Servers and hardware
The purchase of servers accounts for more than two-thirds of the company's annual CO2 emissions. To limit this impact, we have decided to extend the life of our servers to 15 years (compared to an industry average of 3 to 5 years).
In 2024, 88% of the servers purchased in 2015 were still in service. Furthermore, 17% of servers in use benefited from targeted component replacement (processor, memory, storage), avoiding complete replacement while maintaining performance. At end-of-life, our servers are dismantled and recycled.
Contrary to industry practices, we operate them for as long as their performance allows, after optimising them with second-hand components and powered by low-carbon energy.
Extending their use beyond this point would no longer offer any benefits in terms of performance or energy efficiency. We're also aiming for greater transparency in the recycling chain, prioritising circuits that guarantee the reuse of raw materials to at least European standards.

Business trips and overnight stays
All our emissions have been offset 200% since 2018 (100% since 2007), including the impact of server manufacturing and disposal, electricity consumption and daily staff travel. Offsetting projects include a forest reserve in Switzerland and a community reforestation programme in Nicaragua. Each myclimate-project supported offsets 100% of our emissions, ensuring double carbon cover:
Beatenberg-Habkern Nature Forest Reserve
In Switzerland, a Beatenberg-Habkern forest reserve will double CO₂ storage capacity by 2040, thanks to the cessation of logging. This local offsetting is considerably more expensive than projects in developing countries, but it reflects our direct responsibility within our local territory.
Community reforestation
At the same time, we are contributing to a community reforestation project in Nicaragua, using indigenous tree species and with strong local involvement. We're doing this because our impact extends beyond our borders and because in the face of the climate emergency and the limits of offsetting mechanisms, we want to be sure we're doing our bit.
Ultimately, our aim is to offset 100% of our emissions the following year through projects with an immediate impact, without relying on mechanisms whose real benefits on carbon only become tangible after several decades, for example the time it takes for a tree to reach its full storage capacity
Monitoring our water consumption (WUE)
WUE (Water Usage Effectiveness) measures the efficiency of water usage in a data center in order to assess its water impact.
It is calculated according to the following formula:
Total amount of water used by data center (L)
Consommation électrique des équipements informatiques du datacenter (kwH IT)
The closer the WUE is to zero, the higher the water efficiency.
In 2023, Infomaniak's water footprint was 186.8 m3 with an exceptionally low WUE of 0.015. This performance is made possible by a strong technological choice: since 2013, our data centers have operated without mechanical air conditioning, using only direct free cooling, which calls on filtered outside air. During episodes of extreme heat, this device is occasionally supplemented by adiabatic cooling. This involves spraying a very small amount of water at very high pressure to lower the air temperature. Used only in cases of prolonged heatwave, it ensures effective cooling while maintaining minimal water consumption. This combination allows us to reconcile resilience, energy efficiency and responsible water use, placing our infrastructures among the most efficient in the world.
Sustainable mobility
Commuting to and from work accounts for Infomaniak's 2e source of GHG emissions. In 2007, these trips generated 107 tCO₂e, a reduction of 14% compared to 2002.
For the first time since 2013, public transport has become the most widely used mode of transport. 61% of staff have switched to soft mobility or public transport. In 2025, we were awarded the "Ecomobile" label by the State of Geneva, attesting to our commitment to sustainable mobility. This major change is mainly due to a growing collective awareness and an active policy of incentives, with an annual bonus of up to CHF 1’500. This trend is also reflected in the graph below, with the highest rate of soft mobility (61%) ever achieved by the company.

Location-based vs. market-based
Explanations of the GHG Protocol
"The location-based method reflects the average intensity of emissions in the networks where energy is consumed (mainly based on average network emission factor data). The market-based method, on the other hand, reflects emissions from sources deliberately chosen by companies (or the absence of choice).
It derives emission factors from contractual instruments, i.e. any type of electricity purchase or sale contract signed between two parties, including energy attribute certificates or any unbundled energy attribute certificates"
Solar power plants
Our vision is to use solar energy produced during the day to preserve water resources and guarantee renewable availability at night or in bad weather. Glacier water is precious: it must be used exclusively when other renewable energy sources are unavailable.
Self-generation rate of Infomaniak solar power plants in 2024
In 2024, two solar power plants with a total of 1’085 Meyer Burger panels (420 kWp) were commissioned, producing up to 400’000 kWh/year in optimum conditions (6-7% of annual consumption in 2024). Designed in Switzerland and manufactured in Germany using 100% renewable electricity, these panels boast a carbon impact reduced by 36% compared to Asian equivalents (478kg CO₂eq/kWp compared to 750kg for Asian modules).
The energy produced is self-consumed in real time, without passing through the grid, thereby making a direct contribution to the Swiss Confederation's Energy Strategy 2050.
Monitoring our energy efficiency (PUE & ERE)
To measure the energy efficiency of our infrastructures in a transparent and comparable way, we use two recognised indicators: PUE and ERE.
The PUE (Power Usage Effectiveness)
This indicator measures the overall energy performance of a data center. It indicates the proportion of energy used for cooling, lighting and other auxiliary equipment, compared to that directly consumed by the servers.
Total energy used by the data center
Power consumption of the data center IT equipment
The closer the PUE is to 1, the more efficient the data center.
In 2024, the average PUE of Infomaniak's data centers was 1.085, well below the worldwide average of 1.56 (source: Uptime Institute, 2022).
Graph of average Infomaniak PUE over time
The variations observed are mainly due to changes in IT load and outside temperature. They are more pronounced for D3, which relies exclusively on filtered outside air for cooling.

65% of the electrical energy consumed by Infomaniak's new data center was recovered in the form of heat in 2024.
Since it was commissioned for operational testing, our latest data center has achieved an average ERE of 0.231, meaning that around 65% of the total energy consumed is recovered and reused for district heating. This performance is mainly due to the fact that the district heating network operated by SIG is not yet fully operational. At this stage, heat recovery cannot be activated continuously, which mechanically limits the rate of energy recovered. This is therefore a gradual ramp-up phase, until the external infrastructure is fully operational.
The indicators for this data center can be verified in real time on the d4project.org website, which also provides open-source documentation about its operation so that its R&D can be deployed on a large scale throughout our industry.
The ERE (Energy Reuse Effectiveness)
Our vision is to recover 100% of the heat generated by our data centers, transforming a constraint (evacuating the heat produced by the servers) into a useful resource.
It's important to understand that in the virtual world, a data center is not just an invisible infrastructure: it provides computing power and data storage. And in the real world, every watt of electricity consumed by these infrastructures mechanically translates into a watt of heat, which can be used to heat homes, in both summer and winter, connected to a district heating system.
Our ultimate aim is to recover 100% of this "waste" heat and reinject it into a low-carbon district heating system benefiting the whole community.
The ERE therefore assesses the proportion of energy consumed by a data center that is reused (for example, to heat buildings). Unlike other indicators, the ERE includes the PUE in its calculation, making it a more comprehensive tool for assessing a data center's energy performance. It is calculated according to the following formula:
Total energy used by the data center -
Total energy reused
Power consumption of the data center IT equipment
The closer the ERE is to 0, the higher the proportion of energy reused
