[0055] The evaluation unit 25 can identify the user of the work machine 40 to whom an incentive will be granted, based on the user data for identifying the user of the work machine 40 acquired by the user data acquisition unit 23 and the identification data of the work machine 40 to which alternative fuel has been supplied. The evaluation unit 25 generates evaluation data indicating the incentive to be granted to the user of the work machine 40. The evaluation unit 25 transmits the evaluation data indicating the incentive to an information terminal 60 carried by the user via a communications network. The evaluation unit 25 transmits the evaluation data to the information terminal 60 on which application software for using the information processing system 1 is installed. The incentive includes points. The user of the work machine 40 can exchange the points for, for example, merchandise or a gift certificate.

[0056] As described above, the amount of alternative fuel supplied to the work machine 40 is detected by at least one of the liquid level sensor 44 of the work machine 40, the fuel amount sensor 54 of the refueling machine 50, and the fuel amount sensor 34 of the transport vehicle 30. Based on the identification data of the work machine 40, the identification data of the refueling machine 50, and the fuel amount data, the evaluation unit 25 can identify the refueling machine 50 that supplied the alternative fuel to the work machine 40, the work machine 40 to which the alternative fuel was supplied from the refueling machine 50, and the amount of alternative fuel supplied to the work machine 40. Based on the identification data of the work machine 40, the identification data of the refueling machine 50, the identification data of the transport vehicle 30, and the fuel supply amount data, the evaluation unit 25 can identify the transport vehicle 30 that supplied the alternative fuel to the refueling machine 50, the refueling machine 50 to which the alternative fuel was supplied from the transport vehicle 30, the work machine 40 to which the alternative fuel was supplied from the refueling machine 50, and the amount of alternative fuel supplied to the work machine 40. Based on the multiple pieces of identification data, the evaluation unit 25 can identify with a high degree of reliability that alternative fuel has been supplied to the work machine 40, and the user of the work machine 40 to whom an incentive should be awarded.

[0057] FIG. 8 is a diagram illustrating an example of a method for granting incentives according to an embodiment. The evaluation unit 25 may change the amount of the incentive based on the operating location of the work machine 40. The operating location of the work machine 40 refers to the location where the engine of the work machine 40 consumes alternative fuel. As shown in FIG. 8 , the work machine 40 has a position sensor 45 that detects the position of the work machine 40. The position sensor 45 includes a Global Navigation Satellite System (GNSS) receiver that detects the position of the work machine 40 in a global coordinate system using the GNSS. The detection data of the position sensor 45 is transmitted to the on-board controller 43. The on-board controller 43 transmits the detection data of the position sensor 45 to the transaction management device 2 via a communications network. The detection data of the position sensor 45 indicates the operating location of the work machine 40. The evaluation unit 25 changes the amount of the incentive based on the detection data of the position sensor 45.

[0058] The evaluation unit 25 classifies the operating location of the work machine 40 into a first operating location where high cleanliness is required for the exhaust gas from the engine of the work machine 40, and a second operating location where low cleanliness exhaust gas is acceptable. Examples of the first operating location include residential areas or areas around public facilities. Examples of the second operating location include industrial areas or areas around major roads. When diesel is used as engine fuel, the cleanliness of the exhaust gas is likely to be low. When an alternative fuel is used as engine fuel, the cleanliness of the exhaust gas is likely to be high compared to when diesel is used. When the evaluation unit 25 determines, based on the detection data of the position sensor 45, that the work machine 40 is consuming alternative fuel at the first operating location, the amount of the incentive is increased. When the evaluation unit 25 determines, based on the detection data of the position sensor 45, that the work machine 40 is consuming alternative fuel at the second operating location, the amount of the incentive is decreased.

[0059] The evaluation unit 25 may change the amount of incentive based on the type or class of the work machine 40 to which the alternative fuel has been supplied. The evaluation unit 25 can specify the type or class of the work machine 40 based on the identification data of the work machine 40 described with reference to FIG. 7. Examples of types of work machine 40 include excavators, bulldozers, wheel loaders, and dump trucks. Classification refers to the class of the work machine 40 rated according to body size or engine displacement. The type of work machine 40 may affect the amount of fuel consumption per unit work volume. The evaluation unit 25 may increase the amount of incentive the greater the fuel consumption per unit work volume of the work machine 40 that consumes the alternative fuel (the worse the fuel efficiency), and decrease the amount of incentive the lower the fuel consumption per unit work volume (the better the fuel efficiency).

[0060] The evaluation unit 25 also calculates history data showing the transaction history and usage history of the alternative fuel. The history data includes the transaction volume of the alternative fuel in the distribution process of the alternative fuel. When multiple alternative fuels with different properties are distributed, the evaluation unit 25 calculates history data for each of the multiple alternative fuels with different properties. The history data includes the CO２ Emission reduction rate [kg-CO ２ / L]. The evaluation unit 25 stores the calculated history data in the storage unit 26.

[0061] [Method of Granting Incentives] Fig. 9 is a flowchart showing a method of granting incentives according to the embodiment. The emission reduction effect acquisition unit 21 acquires emission reduction effect data of the alternative fuel supplied to the work machine 40. The emission reduction effect acquisition unit 21 acquires the CO reduction effect data of the alternative fuel relative to diesel as the emission reduction effect data of the alternative fuel. ２ The emission reduction rate is acquired (Step S1). The fuel supply amount acquisition unit 22 acquires the fuel supply amount of the alternative fuel supplied to the work machine 40 (Step S2).

[0062] The user data acquisition unit 23 acquires user data for identifying the user of the work machine 40. The user data acquisition unit 23 also acquires identification data for identifying the work machine 40 to which the alternative fuel has been supplied (step S3).

[0063] The emission reduction calculation unit 24 calculates the CO ２ Based on the emission reduction rate and the amount of alternative fuel supplied acquired in step S2, ２ The emission reduction calculation unit 24 calculates the CO reduction of the alternative fuel to diesel oil. ２ The emission reduction calculation unit 24 calculates the amount of CO reduction when the work machine 40 consumes the alternative fuel by the amount of fuel acquired in step S2. ２ The emission reduction amount is calculated (step S4).

[0064] The evaluation unit 25 evaluates the CO calculated in step S4. ２ Based on the amount of emission reduction, the evaluation unit 25 generates evaluation data indicating an incentive to be given to the user of the work machine 40. ２ The greater the amount of emission reduction, the greater the amount of incentive. ２ Evaluation data is generated so that the smaller the emission reduction amount, the smaller the amount of incentive (step S5).

[0065] The evaluation unit 25 also calculates history data showing the transaction history and usage history of the alternative fuel. ２ The evaluation unit 25 stores the calculated history data in the storage unit 26 (step S6).

[0066] The evaluation unit 25 transmits evaluation data indicating the incentive via the communication network to the information terminal 60 possessed by the user. Application software for using the information processing system 1 is installed in the information terminal 60. When the evaluation data is transmitted to the information terminal 60 possessed by the user, an incentive is granted to the user (step S7).

[0067] [Effects] As described above, the transaction management device 2 comprises an emission reduction effect acquisition unit 21 that acquires emission reduction effect data indicating the greenhouse gas emission reduction effect of the alternative fuel; a fuel supply amount acquisition unit 22 that acquires fuel supply amount data indicating the amount of alternative fuel supplied to the work machine 40; an emission reduction amount calculation unit 24 that calculates the amount of greenhouse gas emission reduction in the work machine 40 based on the emission reduction effect data and the fuel supply amount data; and an evaluation unit 25 that grants incentives to the user of the work machine 40 based on the emission reduction amount calculated by the emission reduction amount calculation unit 24.

[0068] According to the embodiment, the evaluation unit 25 increases the amount of incentive the greater the amount of greenhouse gas emission reduction in the work machine 40, and decreases the amount of incentive the smaller the amount of greenhouse gas emission reduction in the work machine 40. The evaluation unit 25 increases the amount of incentive the greater the amount of alternative fuel supplied to the work machine 40, and decreases the amount of incentive the smaller the amount of alternative fuel supplied to the work machine 40. This increases the likelihood that the user of the work machine 40 will actively use alternative fuels. It is possible to encourage the user of the work machine 40 to use alternative fuels that have a high greenhouse gas emission reduction effect.

[0069] Other Embodiments In the above-described embodiment, the emission reduction effect data includes the greenhouse gas emission reduction rate of the alternative fuel relative to diesel. The greenhouse gas emission reduction rate of the alternative fuel is the CO 2 emission reduction rate of the alternative fuel per unit volume relative to diesel. ２ Emission reduction rate [kg-CO ２ The greenhouse gas emission reduction rate of alternative fuels is the CO₂ reduction rate of alternative fuels per unit weight. ２ Emission reduction rate [kg-CO ２ / kg] may also be used.

[0070] In the above-described embodiment, FAME, HVO, e-fuel, and GTL fuel are exemplified as alternative fuels. The alternative fuel may be any fuel that is more effective in reducing greenhouse gas emissions than diesel. Examples of alternative fuels include hydrogen, liquefied petroleum gas (LPG), methanol, ethanol, and ammonia. Note that the fuel may include diesel.

[0071] In the above-described embodiment, the refueling machine 50 and the work machine 40 may communicate via a wireless LAN (Local Area Network) or a wireless PAN (Personal Area Network) at any timing before, during, or after fuel is supplied from the refueling machine 50 to the work machine 40, and the on-vehicle controller 43 may acquire the emission reduction effect data from the refueling machine 50. Alternatively, the on-vehicle controller 43 may acquire the emission reduction effect data from the refueling machine 50 by reading a two-dimensional code provided on the refueling machine 50. The on-vehicle controller 43 may acquire the emission reduction effect data from the refueling machine 50 by non-contact communication such as RFID (Radio Frequency Identification), or may acquire the emission reduction effect data from the refueling machine 50 in a contact-type manner via a connector cable connected to the refueling machine 50. The on-vehicle controller 43 calculates the CO ２The amount of emission reduction may be calculated. The refueling machine 50 may acquire user data by reading a two-dimensional code provided on the work machine 40. The refueling machine 50 and the transaction management device 2 may communicate with each other, and the transaction management device 2 may grant an incentive based on the user data and emission reduction effect data transmitted from the refueling machine 50.

[0072] In the above-described embodiment, some or all of the functions of the transaction management device 2 may be included in the computer of the information terminal 60. A processor of the computer of the information terminal 60 may acquire emission reduction effect data indicating the greenhouse gas emission reduction effect of the alternative fuel, acquire a fuel supply amount indicating the amount of alternative fuel supplied to the work machine 40, calculate the amount of greenhouse gas emission reduction in the work machine 40 based on the emission reduction effect data and the fuel supply amount, and grant an incentive to the user of the work machine 40 based on the amount of emission reduction.
