Abstract: When a device desired to acquire emission right information is selected on a selection screen displayed on a display unit and a “SEND” icon is manipulated, a control unit causes the display unit to display consumables information of consumables granted with emission rights and consumables not granted with emission rights that is received from a server. When a user selects a consumable item that is desired to be ordered from among consumables indicated by the consumables information displayed on the display unit, and manipulates a “SEND ORDER SHEET” icon on the ordering screen, the control unit sends an order sheet to the server. The control unit causes the display unit to display, in the case of receiving order sheet receipt notification from the server in response to the sent order sheet, the received order sheet receipt notification.

Abstract: A communication system is provided. In a communication system, when consumables mounted on an image forming apparatus main body are determined as greenhouse gas emission right-granted consumables by a computation unit, an image forming apparatus acquires contribution content information regarding greenhouse gas reduction corresponding to emission right allowance information recorded in a recording unit of the consumables from a connection unit and displays the acquired contribution content information on a display unit.

Abstract: A control unit displays on the display unit, when a device and a life cycle phase for which an acquisition equivalent and an actual equivalent are desired to be acquired are selected on a selected screen displayed on a display unit and a “SEND” icon is manipulated, the acquisition equivalent, the actual equivalent and a comparison result between them which are received from a server. When a user refers to the comparison result displayed on the display unit and manipulates a “SEND STATEMENT OF ACCOUNT” icon on a settlement screen, the control unit sends a statement of account to the server.
