 For bare metal servers, the allocation of environmental impact is straightforward due to the direct association between a user and a server. The environmental impact of a bare metal server is entirely attributed to the user who operates it. This encompasses the energy consumption during its operation, as well as a portion of the impact from the server's manufacturing process.

-  For the use of an Elastic Metal server, with a lifespan of 6 years (52 560 hours) and power of 110w, for 100 hours and considering via Boavizta estimates that the impact of the manufacturing of this server is 850 kgCo2e, we make the following calculation:
+For the use of an Elastic Metal server, with a lifespan of 6 years (52 560 hours) and power of 110w, for 100 hours and considering via Boavizta estimates that the impact of the manufacturing of this server is 850 kgCo2e, we make the following calculation:
+
+```math
+ServerManufacturing = (100 / 52560) * 850 = 1,62 kgCO2e
+```
+
+Therefore 1,62 kgCO2e is added to the total manufacturing impact of this server.
 
-  ```math
-  ServerManufacturing = (100 / 52560) * 850 = 1,62 kgCO2e

+To calculate the usage, we consider the French energy mix and the datacenter's PUE. In this example, they are O,056kgCo2e/kwh and 1,16, respectively. Which results in:
 
-  Therefore 1,62 kgCO2e is added to the total manufacturing impact for the use of this server.
+```math
+UsageFootprint = 0,110 x 100 x 0,056 x 1,16 = 0,715 kgCo2e
