Sherpa & Company Expands GHG Accounting Expertise

In a significant move towards boosting sustainability efforts within the corporate sector, Sherpa & Company, headquartered in Shinagawa, Tokyo, Japan, has completely acquired Believe Technology, a consultancy known for its expertise in greenhouse gas (GHG) emissions calculation. This acquisition is expected to strengthen Sherpa's position in the realm of sustainability data management via its platform SmartESG.

The Rationale Behind the Acquisition

Sherpa has always aimed for a world where profit and sustainability intertwine seamlessly. Through its innovative SmartESG platform, they have supported over 100 large companies in efficiently and effectively disclosing ESG (Environmental, Social, Governance) data as of April 2026. Sherpa's extensive experience and established foothold have allowed it to become a significant player in the non-financial data management and disclosure landscape.

As the focus on sustainability standards grows stricter, Sherpa recognized the challenges many businesses face, particularly in ensuring the reliability of GHG emission reporting. The complexities of Scope 3 calculations, which involve entire supply chains, necessitate vast data collection efforts and robust evidence management to withstand third-party verification measures.

Believe Technology, based in Kawasaki, Japan, has dedicated itself to supporting domestic companies in their decarbonization efforts. They offer consultation for Scope 1, 2, and 3 emissions calculations, along with educational initiatives that have successfully aided over 100 companies in navigating these challenging waters.

Prior to the acquisition, both firms collaborated under a strategic partnership that launched the AI-native GHG accounting system, SmartESG Carbon, in March 2026. This acquisition cements their collaboration, allowing both parties to integrate Believe Technology's sophisticated knowledge into the SmartESG offering more effectively than before.

Integrating Advanced Expertise into SmartESG Carbon

By fully incorporating Believe Technology’s unique insights into SmartESG Carbon, Sherpa aims to enhance and expedite its response to the growing demand for compliance with Japanese sustainability standards (SSBJ). The integration will facilitate the acceleration of developments that cater to companies' internal control needs concerning sustainable and reliable GHG emission calculations.

The synthesis of both companies' expertise promises a streamlined process for clients between GHG calculation and subsequent information disclosure. This cohesive approach maximizes synergies across Sherpa's entire platform, ultimately equipping businesses with the tools necessary to adopt a more rigorous decarbonization strategy.

Future Perspectives

Join the existing management of Believe Technology as they transition to key roles within Sherpa, notably as part of the SmartESG Carbon business division. The collaboration will springboard a range of new services tailored for companies looking to meet ISSA5000 international auditing standards in an effective manner. This means corporate clients can expect faster and more reliable services that aid in their financial reporting obligations while maintaining strict internal control frameworks.

Sherpa strives to deliver a comprehensive approach, amplifying the proficiency of companies’ decarbonization efforts through both expertise in sustainability and GHG emissions calculations.
