 The estimation is represented by three green leaf icons:
 
-  - When the three leafs are dark green, this means that the AZ has the lowest quantity of CO2e emitted per kW consumed
+  - When the three leafs are dark green, this means that the AZ has the lowest quantity of CO2e emitted per kW consumed, so each kw consumed in you elastic metal will have a lower impact.
   - When two leafs are dark green, this means this that the AZ has a low quantity of CO2e emitted per kW consumed
   - When only one leaf is dark green, the AZ has bigger quantity of CO2e emitted per kW consumed

 ## Elastic Metal offers footprint estimation
 
-For Elastic Metal offers, the environmental footprint estimation considers the impact of the **manufacturing** and **use** of all the elements that allow the service to work, such as network, cross-IT equipment and stock, and non-IT elements, for example.
+For Elastic Metal offers, the environmental footprint estimation considers the impact of the **manufacturing** and **use** of all the elements that allow the service to work, such as network, cross-IT equipment and stock, and non-IT elements, for example. The AZ you chose in the previous step will impact the **use** part by multiplying each kw consumed by each of these elements by the value indicated.

+For usage impact, We base ourselves on an estimate of electricity consumption. This estimation is based on tests carried out by the Hardware team at Scaleway. Each range of offers was tested using different compute configurations to ensure coverage of a variety of possible power consumption setups.
 
 These different compute configurations allow us to simulate enough use cases to have an idea of the power consumption, but the actual consumption will depend on how the server is used in practice.
