Shellpa Launches Innovative AI-Driven GHG Accounting System SmartESG Carbon

Shellpa Introduces SmartESG Carbon: A Revolutionary GHG Accounting System

On March 25, 2026, Shellpa & Company, based in Shinagawa, Tokyo, is set to launch SmartESG Carbon, an AI-native greenhouse gas (GHG) accounting system designed to streamline data handling for Scope 1, 2, and 3 emissions. This system aims to offer robust data management solutions that withstand audits and guarantees.

Shellpa has established a strategic partnership with Believe Technology, a company based in Kawasaki, Kanagawa that specializes in decarbonization support. This collaboration is crucial for enhancing the capabilities of SmartESG Carbon, allowing both companies to combine their strengths in delivering a user-friendly and publicly compliant service.

Background of SmartESG Carbon

As an established player in sustainability information disclosure for listed companies, Shellpa has highlighted a major bottleneck in the reliability of reported data during disclosure practices. Traditional GHG emissions calculations are often encumbered by complex procedures and a reliance on manual processes, particularly in data preparation before estimation. This leads to increased labor efforts and makes it challenging for companies to substantiate their computations during external audits.

Currently, many enterprises still depend on manual data cleansing methods, such as Excel spreadsheets, even after implementing GHG accounting tools. This manual dependency results in a time-consuming process that can stretch over several months. With new disclosure standards from the Sustainability Standards Board of Japan (SSBJ) on the horizon, implementing internal controls that ensure speed, traceability, and reproducibility, similarly to financial reporting, has become imperative.

By introducing SmartESG Carbon, Shellpa aims to tackle the issues surrounding reliability and address the need for high-quality financial-like reporting in emissions calculations.

Collaboration with Believe Technology

In launching SmartESG Carbon, Shellpa has formed a business alliance with Believe Technology. In this partnership, Shellpa will focus on product planning, sales, and integration management with its existing SmartESG series, while Believe Technology will leverage its expertise in GHG accounting and systems development to build a more efficient service.

This partnership not only enhances service offerings but also ensures compliance with regulatory requirements, leading to significant advancements in operational efficiency for clients.

Key Features of SmartESG Carbon

SmartESG Carbon is designed with an evidence-first approach, emphasizing traceability and reliability in GHG accounting. Here are some of its primary features:

1. Data Processing Workflows for Automation
The system automates the data processing workflow by registering company-specific processing rules such as sorting, unit conversion, and mapping. Companies need only upload their data each year, allowing the system to automatically complete the necessary processing steps, significantly reducing errors and labor. AI technology supports the creation of procedural documentation and even provides analytics on year-over-year changes, thus maintaining reliability alongside enhanced efficiency.

2. Traceability and Reproducibility Assurance
With SmartESG Carbon, not only are the emission calculation results recorded, but also every step leading up to the calculations, including sources of coefficients and any changes made. This ensures that the information is readily available for third-party verification while minimizing the time required for confirmations from auditing firms.

3. Seamless Integration with SmartESG Series
All environmental data collected through SmartESG Carbon will conveniently integrate with SmartESG Consolidation, enabling comprehensive analysis in conjunction with human capital data and allowing for prompt external reporting.

Shellpa's Vision

Shellpa envisions a world where profit and sustainability converge. Through the SmartESG platform, the company aims to enhance the operational efficiency of various stakeholders involved in sustainability data.

With over 70 high-profile clients utilizing the SmartESG platform since its launch in November 2022, accounting for 15% of Japan's largest companies, Shellpa is poised to make a significant impact in the realm of corporate sustainability management.
