To provide a carbon dioxide emission amount calculation system for which costs are suppressed and convenience in a household or the like is improved.
An emission amount calculation system 100 comprises operation record measurement devices 10A and 10B for generating operation record data indicating operation time for each electrical equipment, and an emission amount calculation device 20 for calculating an emission amount on the basis of the operation record data. The emission amount calculation device 20 includes: a network interface 21; a storage part 22; an operation record input part 23; an emission amount calculation part 24 for calculating power usage for which power consumption of electrical equipment information tbl1 is multiplied with the operation time in the operation record data, a carbon dioxide emission amount for which a carbon dioxide emission coefficient of user information tbl2 is multiplied with the power usage, and an electricity charge for each electrical equipment by multiplying an electricity charge per unit time with the power usage; a data generation part 25; a data output part 26; and a database 27.
