The world is changing. The decisions facing companies, investors, and boards - on sustainability, governance, risk, and transformation - are more complex, more interconnected, and more consequential than ever before.
The expertise they need is no longer sitting inside large institutions. It is independent, specialist, and distributed across the world. But independent advisors and boutique firms have lacked the infrastructure to deliver at the level their clients now require.
The Global Advisory Alliance exists to change that. We bring together independent ESG professionals and boutique sustainability consulting firms - giving them the collective reach, cross-border capability, and shared credibility to serve clients at the highest level.
Independent expertise. Collective reach.
Every GAA member brings senior, board-level expertise across sustainability, ESG, governance, and transformation - ready to work independently, lead a workstream, or collaborate as part of a cross-border team.
For clients: access the right expertise for the right mandate — one specialist or many, across any geography.
For boutique firms: the Alliance gives you the bench, the reach, and the credibility to say yes to mandates you couldn't take on alone.
That is the gap the Global Advisory Alliance fills.

Choose a starting point that matches your situation today.
Each option helps you test direction, reduce uncertainty, and decide what comes next - without forcing a long commitment.
You face different pressures depending on your market.
• In established markets, cost and bureaucracy slow change. You need external perspective, specialist knowledge and support for leaders driving progress.
• In emerging markets, expectations rise fast. You need credible governance, stronger systems and guidance that signals confidence to investors.
Our value: specialist expertise on demand. You get senior insight without hiring full-time teams, and support exactly when you need it.
