 Our calculation will also incorporate the environmental footprint of all transversal tools essential for the functioning of the Scaleway.
 
-To determine their manufacturing impact, we add the environmental footprint of each machine hosting these transversal tools over the duration of customer usage. This aggregated impact will then be divided by the total number of customers. A "customer" is defined as an active organization, that is to say an organization which consumes and which is billed.
+To determine their manufacturing impact, we add the environmental footprint of each machine hosting these transversal tools over the duration of customer usage. This aggregated impact will then be allocated to each resource based on the electrical power it consumes. The resource's allocated impact will be proportional to its power consumption and in relation to the total power consumption of the infrastructure.
 
 To determine stock manufacturing impact, we will divide the sum of the impact of all hardware components in stock by the total number of servers.

 Finally, our comprehensive environmental impact calculation will include the "Non-IT cross-functional elements." This category encompasses the environmental footprint of all other essential components required for Scaleway's operations, such as office facilities, employee transportation, the company cafeteria, and various logistical aspects.
 
-To integrate this into the overall calculation, we will first get the total environmental impact of these non-IT elements from Scaleway Impact report. This total impact will then be divided by the number of customers. This approach ensures that every customer shares a portion of the environmental burden associated with maintaining the broader operational infrastructure, thereby providing a complete and transparent picture of Scaleway's environmental footprint.
