+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.
+
+The manufacturing impact is prorated based on the server's lifespan and the duration of its use by the customer. By dividing the total manufacturing impact by the expected lifetime of the server and then allocating it according to the specific usage period, we ensure that each user is accountable for their fair share of the server's overall environmental footprint.

+## Calculation example
+
+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.
+
+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:
+
+```math
+UsageFootprint = 0,110 x 100 x 0,056 x 1,16 = 0,715 kgCo2e

+
+For Virtual Instances, the calculation of the environmental footprint takes into consideration all the elements described on the [Environmental Footprint calculation breakdown](/environmental-footprint/additional-content/environmental-footprint-calculator/) documentation page.
+
+## Calculation aspects
+
+The following elements are considered in the Instance footprint calculation:
+  - **Hypervisor resources** - the resources (CPU, RAM, and disk, for example) used in the physical hypervisor servers that create and run the virtual Instances.
+  - **Instance offer resources** - the vCPU, RAM, and disk resources used when you use an Instance.
+
+The calculation using the elements above can be broken down into:
+
+### Manufacturing Impact
+    - Manufacturing of the underlying physical servers (hypervisors) necessary to run the Instances.
+    - Distribution of the manufacturing impact according to the resources consumed by the Instance (vCPU, RAM, storage).
+
+###  Operational Impact
+    - Energy consumption of the hypervisors during Instance usage.
+    - [Power Usage Effectiveness (PUE)](/environmental-footprint/concepts#pue-power-usage-effectiveness) specific to the data center where the Instance is hosted.
+    - Energy mix of the country that provides the electricity.
+
+### Usage Impact
+    - Resources consumed by the Instance, calculated based on the material specifications of the hypervisors.
+
+### Indirect Emissions
+    - Impact related to cross-functional services necessary to guarantee the operation of the Instance, such as network and shared storage.
+
+## Instance consumption ratio
+
+When calculating an Instance's footprint, we consider the resources based on their relative usage on the hypervisor to ensure an accurate distribution of their proportional consumption.
+
+- **CPU** - Consider the share of vCPUs reserved compared to the total number of physical cores available.
+- **RAM** - Consider the share of allocated RAM compared to the total RAM of the hypervisor.
+- **Storage** - Consider the use of allocated storage compared to the total capacity of the hypervisor.
+
+<Lightbox src="scaleway-allocation-rules-instances.webp" alt="" />
+
+The value derived from this calculation will be used in every step of the calculation of the Instance's footprint. The variable is represented as `Resources_Used_VM` in the image above.
+
+Refer to the table below to understand how the `Resources_Used_VM` is integrated into the calculation of each aspect of the total footprint calculation.
+
+To obtain an accurate calculation of the Instance's footprint, we multiply the results in each step of the [basis calculation](/environmental-footprint/additional-content/environmental-footprint-calculator/), bar the Cross-IT equipment & stock calculations step, by the `Resources_Used_VM` ratio.
+
+## Cross-IT equipment calculation for Instances
+
+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.
+
+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.
+
+### Calculation example
+
+In the example below we will calculate the manufacturing impact allocated to an Instance for an 100 hour usage period.
+
+Consider the following characteristics:
+
+| Resource | Instance | Hypervisor |
+| --- | --- | --- |
+| vCPU | 4 | 16 CPU cores |
+| RAM | 8 GB | 64 GB |
+| Storage | 50 GB | 1 TB (1000 GB) |
+| Lifespan (in years) |  | 6 years = 52560h |
+| Manufacturing impact | | 100 kgCo2e |
+
+The allocation of the hypervisor resources for this particular Instance is calculated in the following manner:
+
+| Resource | Allocation |
+| --- | --- |
+| CPU | 4/16 = 0.25 |
+| RAM | 8/64 = 0.125 |
+| Storage | 50/1000 = 0.05 |
+| Total Instance Share | 0.25 + 0.125 + 0.05 = 0.425 |
+
+We multiply the resource allocation by the Instance's lifespan ratio and the hypervisor's manufacturing impact to obtain the manufacturing impact allocated to the Instance:
+
+```
+(100 hours / 52,680 hours) × 100 kgCO2e × 0.425 = 0.080 kgCO2eq
+```

 ## Why does my environmental impact data vary over time?
 
-Your environmental impact data may change due to updates in the energy mix of data center locations, adjustments to PUE, or enhancements in our calculation methodology. These updates ensure that your reports reflect the most accurate and up-to-date information, enhancing transparency and trust in our reporting system.

+## Is hardware equipment recycled at Scaleway?
+
+Scaleway is committed to responsible hardware recycling practices.
+
+All equipment is thoroughly tested in our data centers and repaired whenever possible, with a notable example being the testing of over 45,000 disks in 2024, resulting in a reuse rate of nearly 30%.
+
+For equipment that cannot be repaired, we partner with [Loxy](https://www.loxy.fr/about), a company specializing in the collection, recycling, and reuse of electronic waste.
+
+To ensure transparency and accountability, certificates of treatment or reconditioning are obtained for each batch processed, and our approach is aligned with the European WEEE directive and the internal standards of the Iliad group.
+
+Furthermore, Scaleway maintains rigorous monitoring and reporting procedures, submitting declarations to the relevant state authorities through the [Trackdéchets](https://trackdechets.beta.gouv.fr/) platform.
