Consignor-Level CO2 Emission Allocation in Shared Logistics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems struggle to accurately calculate CO2 emissions for each consignor when a specialized vendor handles logistics for multiple companies, as they lack the necessary granularity to differentiate between individual consignors.
Innovation Solution
A CO2 emission calculation system that includes first, second, third, and fourth calculation units to quantify emissions based on transportation costs, fuel consumption, and energy usage, respectively, with an identifying unit to attribute these emissions to specific consignors, using databases and environmental load intensities to ensure accurate attribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a specialized vendor handles logistics for multiple consignors, then logistics efficiency is improved, but it becomes difficult to accurately understand CO2 emissions for each consignor
Solution Approach 1:
The system segments CO2 emissions data by consignor, payment department, and logistics process stage. The identifying unit divides total emissions into discrete portions attributable to each consignor based on their specific logistics activities, materials, and transportation, enabling precise measurement despite consolidated vendor operations.
2Device complexity
If CO2 emissions are calculated based on aggregated logistics data, then calculation complexity is reduced, but accuracy of emissions attribution to individual consignors deteriorates
Solution Approach 1:
The identifying unit acts as an intermediary between aggregated logistics data and consignor-specific emissions attribution. It uses payment department information, material information, and transportation data as intermediate keys to accurately allocate emissions to individual consignors without requiring complex direct tracking of each consignor's logistics activities.
3Measurement precision
If detailed tracking of logistics activities for each consignor is implemented, then emissions attribution accuracy is improved, but system complexity and data management burden increase
Solution Approach 1:
The system uses universal payment department information that already exists in the logistics management system to simultaneously serve multiple functions: cost allocation, emissions attribution, and consignor identification. This multi-functional use of existing data reduces the need for separate tracking systems while maintaining high attribution accuracy.

AI summary
A CO2 emission amount calculation system, a CO2 emission calculation method, and a program is provided that accurately calculates CO2 emissions related to logistics for each consignor. The CO2 emission amount calculation system includes a first calculation unit that calculates a CO2 emissions based on transportation cost for a material used for the logistics, and an identifying unit that identifies a consignor that produced the calculated CO2 emissions. The CO2 emission amount calculation system further includes a second calculation unit that calculates a CO2 emissions based on energy consumed by transportation of an item, a third calculation unit that calculates a CO2 emissions based on energy consumed by travel of the item in a warehouse site, and a fourth calculation unit that calculates a CO2 emissions based on energy consumed by management of the item within the warehouse site.
