Abstract

In the present invention, at least a single route is created that satisfies route search conditions received from an information processing terminal, an amount of emissions caused by following the created route is calculated on a route-by-route basis, an emission credit purchase amount required for compensating the calculated amount of emissions is calculated, a route search result including the route, the amount of emissions, and the emission credit purchase amount is sent to the information processing terminal, emission amount compensation is performed by subtracting, from the quantity of emission credits stored in a storage unit, the amount of emissions equivalent to the emission credit purchase amount specified in an emission credit purchase order received from the information processing terminal, and a compensation result at least including the compensated amount of emissions and the corresponding emission credit purchase amount to the information processing terminal is sent for display.

Claims

1. A route searching apparatus comprising a control unit and a storage unit and being communicably connected to an information processing terminal comprising an input unit and a display unit and that is possessed by a user seeking carbon offsets, wherein

the storage unit includes:

a route-search-information storage unit that stores route search information including timetable data of transport modes and road network data;

an emission-amount calculation-standard storage unit that stores a calculation standard for an amount of emissions of a greenhouse effect gas over a certain distance with respect to each of the transport modes; and

an emission-credit-quantity storage unit that stores a quantity of emission credits of the greenhouse effect gas on a user-by-user basis, and

the control unit includes;

a route creating unit that receives a route search condition input by the user via the input unit from the information processing terminal, and creates at least a single route that satisfies the received route search condition using the route search information stored in the route-search-information storage unit;

an emission amount calculating unit that calculates the amount of emissions on a route-by-route basis when at least the single route created by the route creating unit is followed using the calculation standard stored in the emission-amount calculation-standard storage unit;

an emission-credit-purchase-amount calculating unit that calculates an emission credit purchase amount required for compensating the amount of emissions calculated by the emission amount calculating unit;

a route-search-result displaying unit that sends a route search result including at least the single route created by the route creating unit, the amount of emissions calculated by the emission amount calculating unit, and the emission credit purchase amount calculated by the emission-credit-purchase-amount calculating unit to the information processing terminal for display on the display unit;

an emission amount compensating unit that compensates the amount of emissions by receiving an emission credit purchase order for the emission credit purchase amount corresponding to the route selected by the user via the input unit based on the route search result displayed by the route-search-result displaying unit from the information processing terminal, and subtracting the amount of emissions equivalent to the received emission credit purchase amount from the quantity of emission credits stored in the emission-credit-quantity storage unit; and

a compensation result displaying unit that sends a compensation result including at least the amount of emissions compensated by the emission amount compensating unit and the emission credit purchase amount corresponding to the amount of emissions to the information processing terminal for display on the display unit.

2. The route searching apparatus according to claim 1, wherein

the control unit further includes:

a billing unit that charges to the user the emission credit purchase amount calculated by the emission-credit-purchase-amount calculating unit.

3. The route searching apparatus according to claim 1, wherein

the storage unit further includes:

a history information storage unit that stores history information that includes the route search result and the compensation result in at least a partially corresponding manner on a user-by-user basis,

the route-search-result displaying unit stores at least a part of the route search result in the history information storage unit on a user-by-user basis, and

the compensation result displaying unit stores at least a part of the compensation result in the history information storage unit on a user-by-user basis.

7. The route searching apparatus according to claim 2, wherein the storage unit further includes:

a history information storage unit that stores history information that includes the route search result and the compensation result in at least a partially corresponding manner on a user-by-user basis,

the route-search-result displaying unit stores at least a part of the route search result in the history information storage unit on a user-by-user basis, and

the compensation result displaying unit stores at least a part of the compensation result in the history information storage unit on a user-by-user basis.

4. A route searching method executed by a route searching apparatus including a control unit and a storage unit and being communicably connected to an information processing terminal including an input unit and a display unit and that is possessed by a user seeking carbon offsets, wherein

the storage unit includes:

a route-search-information storage unit that stores route search information including timetable data of transport modes and road network data;

an emission-amount calculation-standard storage unit that stores a calculation standard for an amount of emissions of a greenhouse effect gas over a certain distance with respect to each of the transport modes; and

an emission-credit-quantity storage unit that stores a quantity of emission credits of the greenhouse effect gas on a user-by-user basis, and

the method comprising;

(i) a route creating step of receiving a route search condition input by the user via the input unit from the information processing terminal, and creating at least a single route that satisfies the received route search condition using the route search information stored in the route-search-information storage unit;

(ii) an emission amount calculating step of calculating the amount of emissions on a route-by-route basis when at least the single route created at the route creating step is followed using the calculation standard stored in the emission-amount calculation-standard storage unit;

(iii) an emission-credit-purchase-amount calculating step of calculating an emission credit purchase amount required for compensating the amount of emissions calculated at the emission amount calculating step;

(iv) a route-search-result displaying step of sending a route search result including at least the single route created at the route creating step, the amount of emissions calculated at the emission amount calculating step, and the emission credit purchase amount calculated at the emission-credit-purchase-amount calculating step to the information processing terminal for display on the display unit;

(v) an emission amount compensating step of compensating the amount of emissions by receiving an emission credit purchase order for the emission credit purchase amount corresponding to the route selected by the user via the input unit based on the route search result displayed at the route-search-result displaying step from the information processing terminal, and subtracting the amount of emissions equivalent to the received emission credit purchase amount from the quantity of emission credits stored in the emission-credit-quantity storage unit; and

(vi) a compensation result displaying step of sending a compensation result including at least the amount of emissions compensated at the emission amount compensating step and the emission credit purchase amount corresponding to the amount of emissions to the information processing terminal for display on the display unit,

wherein the steps (i) to (vi) are executed by the control unit.

5. The route searching method according to claim 4, the method further comprising:

a billing step of charging to the user the emission credit purchase amount calculated at the emission-credit-purchase-amount calculating step.

6. The route searching apparatus according to claim 4, wherein
