• The Series D brings ASUENE’s total funding to $161 million and includes $43.8 million in new capital.
• Decarbonization Partners, backed by BlackRock and Temasek, led the fund’s first investment in Japan.
• ASUENE plans international acquisitions as sustainability disclosure rules reshape supply-chain data markets.

Japanese sustainability technology company ASUENE has raised $87 million in Series D funding to expand its global operations, accelerate acquisitions and deepen its artificial intelligence capabilities.

Decarbonization Partners led the round. The investment platform is a joint venture between BlackRock and Temasek and focuses on companies supporting the transition to a lower-carbon economy. The transaction is the fund’s first investment in Japan.

ASUENE has now raised $161 million in total funding. The latest financing will support its push into sustainability disclosure and supply-chain management markets across Europe, North America and Asia.

Funding supports international acquisition strategy

The Series D includes $43.8 million in new capital and $19.3 million in debt financing from Sumitomo Mitsui Banking Corporation. Eight new and existing investors participated, including Japanese companies DAIKIN and RICOH.

ASUENE did not provide a full breakdown of the remaining portion of the announced $87 million round.

The company plans to use the proceeds for mergers and acquisitions, product development and business expansion. It will also invest in AI-driven services and launch new business lines.

International M&A will form a central part of that strategy. ASUENE is positioning itself as a serial acquirer in sustainability software, consulting and supply-chain data.

The company is targeting further growth in the United States, United Kingdom and European Union. These markets are introducing more detailed requirements for climate, corporate and supply-chain reporting.

For sustainability technology providers, this regulatory expansion is creating demand for platforms that can collect emissions data and connect disclosure obligations with operational decision-making.

Decarbonization Partners’ involvement gives ASUENE access to two major global investment institutions. It also reflects growing investor interest in the infrastructure needed to support corporate decarbonisation.

Dr. Meghan Sharp, Global Head and CIO of Decarbonization Partners, said: “As companies face increasing expectations to measure and reduce emissions across their operations and supply chains, sustainability data is evolving from a reporting requirement into a strategic business tool. ASUENE enables organizations not only to meet evolving disclosure requirements, but also to use emissions data to improve efficiency and drive better business outcomes. We’re excited to partner with the ASUENE team as they expand as an international integrated sustainability services company.”

The investment comes as companies face pressure to improve the quality, consistency and auditability of sustainability information. Scope 3 emissions remain a particular challenge because they depend on data collected from suppliers, customers and other external partners.

ASUENE aims to address that problem through an integrated platform covering emissions accounting, disclosure management and supply-chain sustainability.

Its longer-term ambition is to become the global standard for enterprise sustainability management. It also wants to establish a common platform for manufacturing supply chains, where emissions data often spans thousands of suppliers.

AI and regulation drive market expansion

ASUENE’s strategy combines software development with acquisitions that can expand its geographic reach and service offering.

Kohei Nishiwada, Founder and Chief Executive Officer of ASUENE, said: “We’re honored to announce the close of our Series D round, a total of US$87 million, led by Decarbonization Partners, BlackRock’s dedicated decarbonization investment fund.

This was a complex, high-stakes deal that took roughly ten months to bring home, involving a wide range of investors and stakeholders. We navigated it against a backdrop of rapid change in the market, most notably the rise of generative AI, and worked through no shortage of hard problems along the way. That we reached this close is a testament to the dedication and drive of everyone involved, inside and outside the company. To all of them, my deepest respect and gratitude.

Alongside world-class institutional investors like BlackRock and Temasek, our team is moving as one to accelerate further M&A, expansion across Japan, global growth, and our shift to AI sustainability integrated company. As an AI sustainability integrated platform built in Japan and taking on the world, we’re committed to driving social impact and creating value at a scale never seen before.”

For executives and investors, the financing highlights the convergence of regulation, operational data and corporate climate strategy. Sustainability platforms are increasingly expected to do more than produce annual reports.

They must also help companies manage supplier risk, control costs and respond to changing disclosure rules.

ASUENE’s global expansion will test whether a Japan-based platform can build that infrastructure across multiple regulatory systems. Its success could also shape how manufacturing companies standardise emissions data across international supply chains.
