SUPPORT DEVICE

To provide a support device capable of facilitating reduction of a carbon dioxide discharge amount.SOLUTION: A support device comprises: a registration part 11 which registers, for each of a plurality of employees, a plurality of places of work, and a plurality of commutation paths for going to the places of work, the plurality of commutation paths being registered and associated with a predetermined priority level; a storage part 12 for storing, for each of the plurality of registered commutation paths, at least a carbon dioxide discharge amount of carbon dioxide which is estimated to be discharged when commuting along the commutation path; a selecting part 13 for receiving input of the place of work by an employee; and a calculation part 14 for determining a total amount being a total sum of a carbon dioxide amount of carbon dioxide which is estimated to be discharged when a plurality of employees commutes on the basis of a first commutation path with the highest priority level out of the plurality of commutation paths for going to the place of work input to the selecting part 13.SELECTED DRAWING: Figure 1 【課題】二酸化炭素の排出量削減を図りやすくする支援装置を提供する。【解決手段】複数の従業員のそれぞれについて、複数の勤務場所、および、勤務場所に向かう複数の通勤経路が登録され、複数の通勤経路については予め定められた優先順位と紐付けされて登録される登録部１１と、登録された複数の通勤経路のそれぞれについて、通勤経路に沿って通勤した際に排出されると推定される二酸化炭素量が少なくとも記憶される記憶部１２と、従業員による勤務場所の入力を受け付ける選択部１３と、選択部１３に入力された勤務場所に向かう複数の通勤経路のうち優先順位が最も高い第１通勤経路に基づいて、複数の従業員が通勤する際に排出されると推定される二酸化炭素量の合計である合計値を求める演算部１４と、が設けられたことを特徴とする。【選択図】 図１
