The Global Advisory Alliance member firms are led by practitioners who've held senior roles at HSBC, EY, Shell, Credit Suisse, CGI, WWF, and leading law firms. They bring decades of real-world experience across climate finance, governance, compliance, and investor strategy.
GAA firms specialise in investor relations, shareholder engagement, activist defence, and sustainable investment governance - serving listed companies and asset owners worldwide.
Independent governance advisors within GAA serve boards, investors, and leadership teams globally — bringing senior expertise without the overhead of a large consultancy. Our members advise on board effectiveness, corporate strategy, and decision-making frameworks.
GAA firms help organisations manage technology risk and modernise operations - advising on digital transformation, cybersecurity, AI governance, and ESG technology platforms.
Our members help companies and investors turn reporting obligations into strategic advantage - across ESG data management, reporting frameworks (CSRD, SFDR, GRI), audit readiness, and assurance.
GAA members advise on net zero strategy, GHG accounting, nature-based solutions, carbon markets, and environmental compliance. Our firms work with companies and investors navigating the transition to a low-carbon economy - across every major market.
Our members bring sector depth across industries where human capital defines performance - supporting leadership development, culture, people strategy, and organisational change.
GAA member firms operate independently across five continents. Each firm is admitted to the alliance on the basis of senior leadership, sector expertise, and commitment to the GAA code of conduct.
