Building Bridges in Tokyo: Advancing Carbon Data Collaboration Across Japan and APAC

Tokyo, October 2025. Over one week in Japan, the Partnership for Carbon Transparency (PACT) engaged business leaders, policymakers, and technology innovators to advance a shared goal: make carbon data exchange practical, interoperable, and valuable for companies across the Asia-Pacific region. From WBCSD’s Tokyo Connect to workshops at Fujitsu Uvance Kawasaki Tower, and discussions at the Combined Exhibition of Advanced Technologies (CEATEC) and the International Open Forum on Data Society (IOFDS), the trip underscored Japan’s growing role in shaping transparent, data-driven decarbonization and connecting domestic innovation with emerging regional initiatives.

Japan: A country moving from dialogue to delivery

Japan’s corporate climate strategy is entering a new phase of implementation. While global regulations such as the EU CBAM are closely monitored by businesses with international operations,  Japanese companies are focused on advancing domestic priorities, from Japan's Green Transformation (GX) policy and the expanding J-Credit system to new Digital Product Passport (DPP) frameworks. The message throughout the week was clear: decarbonization is no longer an abstract policy goal but a pathway to competitiveness and innovation.

For many leaders, carbon transparency is now seen as a tool to strengthen domestic supply-chain resilience and regional trade integration, linking Japan with emerging efforts, across Southeast Asia, particularly in China, Korea, and Taiwan.

From vision to practice: WBCSD Tokyo Connect

At WBCSD Tokyo Connect 2025, PACT co-hosted a panel with SAP, bringing together sustainability and digital-transformation leaders from across industries to explore how carbon transparency can accelerate value-chain decarbonization.

Peter Bakker, WBCSD President & CEO, emphasized the message that globally carbon accounting is shifting from compliance to a strategic driver for innovation and competitiveness. Naama Avni-Kadosh, Director of PACT, translated this vision into action, calling on companies to adopt standardized methodologies like PACT, exchange product-level data securely, and embed carbon insights into procurement and design decisions.

A panel featuring SAP and Fujitsu brought implementation stories to life, showcasing how digital tools, supplier engagement, and cross-industry collaboration are turning data into measurable decarbonization progress.

The discussions highlighted that Japan’s strengths in namely precision engineering, disciplined data management, and trusted long-term supplier relationships, form a powerful foundation for scaling product-level transparency.

Implementation in Action: Fujitsu

At Fujitsu Uvance Kawasaki Tower, sustainability, supply-chain, and engineering experts demonstrated how PACT Conformant data exchange is being embedded in real business systems. Product-level carbon footprints (PCFs) can now be transmitted via API across value chains, supporting both domestic reporting and international interoperability. The focus was on collaboration over comparison, sharing primary data to enable joint improvement rather than supplier ranking.

Fujitsu’s leadership in integrating circular-data-exchange principles and aligning with PACT’s global methodology highlights the company’s role as a bridge between Japan’s national digital-transition agenda and international carbon-accounting standards.

Linking global methods to global standards

Conversations with key stakeholders during the week, including the Green × Digital Consortium (GxD) - a consortium of over 150+ Japanese companies - highlighted Japan’s unique approach to decarbonization through data. By combining corporate-level and product-level accounting, Japanese companies are embedding environmental data into their overall management systems.

The dialogues underscored a shared ambition: ensuring that domestic initiatives remain interoperable with international frameworks while reflecting Japan’s industrial structure and regulatory context.

Key takeaways from Japan

1. Domestic focus, global relevance: Japan’s Green Transformation (GX) and J-Credit systems dominate the national climate agenda, but companies are increasingly looking for tools that connect domestic reporting with international standards.
2. Partnership over pressure: Collaboration and trust, rather than compliance pressures, define supplier engagement strategies and drive progress
3. Circularity meets transparency: Many Japanese stakeholders see circular data exchange as the next frontier, linking material traceability, recycling, and carbon accounting.
4. Regional opportunity: With strong ties to Korea, Taiwan, and Southeast Asia, Japan can act as a catalyst for an interoperable APAC carbon-data ecosystem.

Gratitude and collaboration

WBCSD and PACT extend sincere thanks to Fujitsu, SAP, GxD, and all partners who contributed their insights and openness throughout the week. Together, these discussions strengthened the bridge between global ambition and regional implementation, a vital step toward transparent, credible Scope 3 action.

As momentum grows across APAC, PACT remains committed to helping every company - regardless of size or geography -access the tools, standards, and partnerships needed to decarbonize value chains with confidence.
