According to the present invention, a route covered by travel expenses and satisfying a route search condition input by a member of a group who wishes an adjustment of travel expenses is created, and greenhouse gas emissions emitted at a time of using the created route are calculated. The greenhouse gas emissions are offset by subtracting the calculated greenhouse gas emissions from an amount of emission credits stored in a storage unit, and it is determined whether the greenhouse gas emissions have been offset. When it is determined that the greenhouse gas emissions have not been offset, a display unit is caused to display a travel-expense-application rejection notification indicating that an application for an adjustment of travel expenses applied by the member is rejected. |
