Abstract
In order to disclose an emission allowance for each product and allow its trading on a product unit basis, the present invention manages, in a management server requesting execution of a settlement process to settlement servers which make settlement of the emission allowance, weight information of the emission allowance and identification information of a non-contact IC medium in association with each other and stores, in databases provided in the settlement servers, weight information of an emission allowance on a seller's side, seller's account information, weight information of an emission allowance on a buyer's side, and buyer's account information. When the non-contact IC medium removed from a product bought from the seller's side is sent from the buyer's side, a withdrawal process from the seller's account and a transfer process to the buyer's account are performed in the settlement servers in relation with the emission allowance traded between the seller's side and the buyer's side, based on the transmitted execution request of the settlement process and the information stored in the databases.
