PCA Corporation (Representative Director and President: Fumiaki Sato, Headquarters: Chiyoda-ku, Tokyo, Prime Market Code: 9629, hereafter: PCA), which develops and sells cloud-based core business systems including 'PCA Arch' that provides one-stop support for finance/accounting, HR/labor, and sales management utilizing AI technology, announces that it has started API integration with 'COxCO Karte', a service provided by SCSK Corporation (Headquarters: Koto-ku, Tokyo, Representative Director, Executive Officer and President: Takaaki Toma, hereafter: SCSK). By simply uploading daily accounting data accumulated in PCA software to the cloud service, a uniquely developed algorithm calculates CO2 emissions.
Through this integration, companies using 'PCA Cloud Accounting' can utilize their journal and account title data accumulated through daily accounting tasks directly for emission calculation. No specialized settings or additional work is required; CO2 emissions can be automatically calculated and visualized using only accounting data.
1. Background and Purpose: Expected Rapid Increase in Requests for Emission Data Submission from Business Partners Due to Decarbonization Across the Supply Chain
Since 2024, climate-related information disclosure by companies has been rapidly strengthened both domestically and internationally. With the introduction of the European CSRD*1 and ISSB*2, the disclosure of emissions across the entire supply chain is becoming 'de facto mandatory.' In Japan as well, against the backdrop of the full-scale launch of GX-ETS*3, a rapid increase in requests to suppliers for emission data submission is expected.
On the other hand, many mid-tier and small-to-medium enterprises often do not have an established calculation framework in place, creating situations where they cannot meet the requests of their business partners. To solve these challenges, SCSK provides 'COxCO Karte', which can automatically calculate CO2 emissions using only accounting data.
With the integration of 'PCA Cloud Accounting' and 'COxCO Karte', we will support users across a wide range of industries in streamlining their decarbonization efforts.
*1 A new system for corporate sustainability information disclosure established by the European Union (EU)
*2 International standards for sustainability information disclosure formulated by the International Financial Reporting Standards (IFRS) Foundation
*3 An emissions trading system being introduced by the Japanese government
2. Main Values Realized by the Integration of 'COxCO Karte' and 'PCA Cloud Accounting'
'COxCO Karte' is a service that can calculate CO2 emissions based on the accounting data held by a company. Through this API integration, the connection with 'PCA Cloud Accounting' is automated, providing a calculation environment with an even lighter burden.
(1) Zero Calculation Work Required, with 'Not Even a Need to Import' Accounting Data
Journal and account title data from 'PCA Cloud Accounting' are automatically linked to 'COxCO Karte', eliminating the need for preprocessing such as exporting or uploading CSV files. Emission calculation can be completed as an extension of daily accounting tasks, making it easily adoptable even for mid-tier and small-to-medium enterprises.
(2) Establishing a Framework to 'Immediately Respond' to Emission Submission Requests from Business Partners
Companies can respond to emission submission requests from suppliers without additional investment or specialized knowledge. Furthermore, because the data required for submission is constantly updated, it is possible to respond to sudden requests without delay.
(3) Simultaneously Visualizing Emissions and Costs to Support Management Decisions
