Finance Function Forums
A4S convenes senior finance, accounting and risk professionals who are integrating sustainability data throughout the organization and shaping the future of high-quality sustainability disclosure. Our forums provide trusted, practitioner-led spaces where leaders can compare approaches, share real-world experience and stay ahead of rapidly evolving expectations in a Chatham House Rule environment. Each forum focuses on a different part of the sustainability information value chain, ensuring targeted insight while contributing to a connected community.
The A4S Controllers Forum was established in 2023 and was joined in 2024 by the A4S Internal Audit and Risk Management Forum. In 2026, we will welcome the new A4S Capital Planning Forum.
70+ organizations involved in the Forums
Since their inception, the A4S Forums have grown significantly, with participation from across North America, Europe, and the Asia Pacific region. Below are our co-chairs of the forums.
