To provide a system for efficiently evaluating the environmental load in every activity and reflecting the evaluation result in pay.

An environmental load evaluation reflecting server 2 is connected to an environmental load calculation DB3 including environmental load calculation information (resource and environmental load) 30, a managed person DB4 including pay information 41, a business result DB5 including activity information 50 and an evaluation DB6 including activity target information 61 and counterpart activity environmental target information 62, and provided with an environmental load calculating means 20 by each activity, a counterpart activity environmental evaluating means 27, an activity evaluating means 28 and a pay information updating means 29. The activity information 50 includes activity information 51, process information 52 on each activity, and activity actual result information 53 for each managed person. In the means 20, with reference to the activity DB5, environmental load in a designated period by each managed person is assigned to the activity to calculate the environmental load amount by each activity. In the means 27(28), the environmental load amount (information 53) by each activity is compared with the target value (information 61) of the information 62 to evaluate the environmental load (evaluate the activity). In the means 29, pay information 41 is updated on the basis of evaluation.
