Environmental Leadership
Responsible sustainability
Scaleway is committed to limiting the environmental impact of the cloud, in line with parent company iliad Group's SBTi-validated objective to reduce scope 1, 2 & 3 emissions by 90% by 2050 (vs. 2022). We innovate constantly to take our sector to new levels of sustainability, by offering responsible products and services which limit our clients' impact on the planet.
Impact Report
Every year, Scaleway reports transparently on key ESG indicators, covering our commitments to our People, to the Environment and to Society at large. Download our latest report to discover key indicators such as PUE+WUE (power and water usage effectiveness), CO2eq emissions (scopes 1, 2 & 3), hardware reuse, customer satisfaction ratings and staff diversity.
Scaleway's environmental commitments
Optimizing energy
Scaleway strives to use as little energy as possible. Our average PUE (Power Usage Effectiveness) is 1.37 in 2024, well below the industry average (1.55). Technological innovations are not achieved at the expense of the environment. For our most demanding infrastructures, such as our AI clusters, we have optimized our PAR-DC5 data center to maintain a PUE of 1.25 while ensuring optimal cooling conditions. This performance offsets the high consumption of our GPUs with leading energy efficiency.
Minimizing water consumption
While many cloud providers use millions of cubic meters of drinking water in cooling towers to cool their data centers, Scaleway refuses to engage in this practice. Our PAR-DC3 and PAR-DC4 data centers illustrate our leadership with a WUE (Water Usage Effectiveness) of only 0.00009 for the former and 0.00002 for the latter.
Defending the circular economy
Sustainability is also achieved by extending the lifespan of our equipment. We have implemented ambitious circular economy programs for our servers and components. In fact, the Transformers program has enabled the reconditioning of nearly 15,000 servers, extending their lifespan to up to 10 years (compared to 5 to 6 years for the rest of the industry), and the Nursery program has enabled the reconditioning of more than 12,000 hard drives in 2024.
Measurable excellence
Scaleway's Environmental Impact Calculator is the most far-reaching of the entire cloud sector, covering carbon emissions (scopes 1, 2 & 3), individualized hardware impacts and water consumption. More information here. Scaleway also advises French national ecological agency ADEME on key referentials like PCR Cloud; EcoVadis granted Scaleway its Gold Medal early 2024, putting us in the top 5% of its most sustainable companies; and the Green Web Foundation has reconfirmed our website is "Hosted Green".
