# Environmental Impact Wizard
As discussed in the Step-by-Step guide to Environmental Impact, environmental impact parameters for a material type may be specified in the Environmental Impact Wizard. This wizard can be accessed either from the Environmental Impact Specification dialog to specify global parameters, or from the material grades to specify values for a particular user material.
# Definition
Enter Specified values for each environmental parameter.
When the Environmental Impact Wizard is accessed from the Material Wizard for a concrete material type, separate tabs are offered to enable environmental parameters to be specified for both concrete and rebar.
Import
The Import button will launch a connection to the Veracity carbon database, allowing the environmental parameters to be imported for a particular material. Use the "Select" button in the material details page to import the values for that material. Note that this feature is only available for Arup staff and requires connection to the Arup network.
