 ## Cross-IT equipment calculation for Instances
 
-The only part of the calculation that will differ from the basis is the [Cross-IT equipment & stock calculations](/environmental-footprint/additional-content/environmental-footprint-calculator/#cross-it-equipment-and-stock).
+The only part of the calculation that will differ from the basis is the [Customer Servers](/environmental-footprint/additional-content/environmental-footprint-calculator/#customer-servers) section.
 
 To calculate the electrical consumption of Instances, instead of using an exact measure of the power consumption, we use a proxy, e.g. CPU usage. The relationship between CPU usage and the power consumption of the underlying machine is non-linear, and characterised by a consumption profile.
 
 A consumption profile is a formula that takes in a given workload (e.g. % CPU usage), and returns the estimated power consumption of the machine.
 
 We use the [consumption profiles defined by Boavizta](https://doc.api.boavizta.org/Reference/routes/#consumption-profile-routes) for the CPUs used on Scaleway Instances.
 
-Initially we base the calculation on a [theoretical value](/environmental-footprint/additional-content/environmental-footprint-calculator-estimation/) of 30% CPU usage.
+For the [Environmental Footprint Estimation](/environmental-footprint/additional-content/environmental-footprint-calculator-estimation/), we base the calculation on a theoretical value of 30% CPU usage. On your [monthly report](/environmental-footprint/how-to/track-monthly-footprint/), we use your real CPU consumption to provide you with the most reliable data possible.
