A4S Summit 2027

A4S Summit 2027 is a three-day invitation-only sustainability and finance leadership summit taking place from 7 to 9 June 2027 in London, United Kingdom. Now in its 22nd year, the summit brings together CFOs and senior finance leaders from major businesses, capital markets, accounting, regulation, and other financial institutions for peer-level discussions on the strategic challenges shaping business performance, long-term value creation, and the transition to a sustainable economy.

Purpose and Objectives

The primary purpose of the A4S Summit is to provide a senior forum for finance leaders to examine how sustainability is changing business strategy, markets, risk management and capital allocation. The summit focuses on sharing practical experience and identifying how finance functions can help organisations manage emerging risks while capturing opportunities associated with the transition to a sustainable economy.

Key Activities

The summit features high-level roundtables, plenary discussions, peer-to-peer dialogue, and keynote sessions. Discussions are designed to encourage candid exchange between senior finance leaders facing similar strategic challenges, with topics spanning sustainable business performance, capital markets, risk, investment, regulation, and long-term value creation.

Significance

The A4S Summit is significant because it brings sustainability directly into the discussion among senior finance and capital-market decision-makers. Its invitation-only format creates a focused environment for CFOs and other leaders to exchange practical experience on how sustainability considerations are influencing financial strategy, risk and business performance.

Expected Outcomes

Participants can expect peer perspectives on emerging sustainability and financial-market developments, strategic risks and opportunities, and approaches to integrating sustainability into finance and business decision-making. The summit is designed to support high-level collaboration, knowledge exchange and practical action across the finance community.
