Sherpa & Company acquires Believe Technology to unify GHG reporting
What's the deal? Sherpa & Company, a Tokyo-based sustainability data platform provider, has fully acquired Believe Technology, a Kawasaki-based consultancy specialising in greenhouse gas (GHG) emissions calculation. The deal makes Believe Technology a wholly owned subsidiary. Sherpa will absorb Believe Technology's team into a new dedicated business unit for its AI-native emissions platform, SmartESG Carbon, which the two firms had been jointly developing since a March 2026 partnership.
Sherpa's SmartESG platform serves roughly 100 large enterprises whose combined market capitalisation exceeds US$2.31T. Believe Technology has consulted for more than 100 companies on Scope 1–3 emissions accounting.
Why now? Japan's Sustainability Standards Board (SSBJ) is tightening disclosure requirements, pushing companies to produce audit-ready emissions data — especially for complex Scope 3 supply-chain calculations. The international assurance standard ISSA 5000 is also raising the bar, demanding the same rigour applied to financial statements.
Companies face a dual burden: collecting vast amounts of activity data across supply chains while maintaining evidence trails that can withstand third-party assurance. Sherpa says the acquisition lets it merge Believe Technology's deep calculation expertise with its own NLP and large language model capabilities to tackle both problems at once.
What could go wrong? Integrating a consulting-heavy team into a SaaS-driven organisation is never straightforward. Cultural and operational differences could slow product development rather than accelerate it. The market for GHG accounting tools in Japan is also getting crowded, and rivals are embedding similar AI features into their own platforms.
Additionally, SSBJ standards are still evolving. If timelines shift or requirements change, the urgency that justifies the deal could soften, making it harder to convert pipeline interest into paying customers.
The signal: The deal reflects a broader pattern: sustainability software companies are acquiring domain-specific consultancies to move from pure disclosure support to end-to-end emissions management. As regulators worldwide push non-financial reporting toward the same assurance standards as financial reporting, platforms that combine calculation know-how, audit-grade evidence management, and AI automation are positioning themselves as essential infrastructure.
Believe Technology's existing leadership will take senior roles in Sherpa's new Carbon division, signalling that the acquirer values operational continuity. The combined entity plans to offer a seamless workflow from raw emissions data through to regulatory disclosure — a capability set that large Japanese corporates increasingly demand as SSBJ deadlines approach.
