“Transition Planning Symposium” Hosted by A4S

On Monday, March 23, 2026, the Transition Planning Symposium was held in Tokyo. Organized by the non-profit organization Accounting for Sustainability (A4S), this in-person event brought together approximately 30 practitioners from corporate finance, strategic planning, and sustainability departments, as well as representatives from financial institutions and investors. The symposium served as a platform for dialogue and knowledge sharing from a practical perspective regarding the formulation of climate transition plans and their integration into financial strategies.

The symposium  discussed global decarbonization trends and the current state of GX (Green Transformation) promotion in Japan. It was  emphasized that “Transition Finance” is becoming established as a pillar as vital as Green Finance, and shared expectations for the financial sector’s role in supporting corporate decarbonization processes.

In this context, A4S provided a practical walkthrough based on the A4S guide for finance teams, “Aligning Transition Planning and Financial Planning.” , explaining that  how high-quality transition plans can be embedded into corporate management and financial strategies to drive the creation of corporate value.

During the table discussions—partially facilitated by CAJ—participants engaged in a candid exchange of views that transcended their different roles as corporations or investors. The dialogue focused on:

• Practical challenges in achieving decarbonization.
• Securing executive commitment essential for plan execution.
• Methods for building organizational consensus.

The symposium featured discussions incorporating case studies, evolving beyond simple knowledge sharing into a meaningful “peer learning” environment where participants learned from one another’s direct experiences.

In Japan, the full-scale operation of the GX-ETS (Emissions Trading System) means that emission reductions will now be directly reflected in financial performance. Companies have moved past the stage of simply committing to Net Zero targets; they are now required to take concrete action in line with their transition plans.

To accelerate practical action toward the Net Zero transition, CAJ remains committed to fostering communities and providing environments—such as this symposium—where expertise and insights can be shared.
