The Global ESG Stewardship Ecosystem

Can shareholders carry out collective engagement on a global scale?

Tim Bowley and Jennifer G. Hill analyse the emergence of a « global ESG stewardship ecosystem » in their article « The Global ESG Stewardship Ecosystem ».

They provide a conceptual overview of how a transnational network of institutional investors, international organisations, NGOs, investor alliances, and service providers collaborate across borders to set shared stewardship norms and coordinate engagement with companies.

The authors highlight the scale, complexity, and influence of this ecosystem in modern corporate governance, using examples of investor coalitions and stewardship codes to illustrate how it operates.

Their main observations include:

• A vast global network now drives ESG stewardship: institutional investors, together with organisations like the UN, NGOs, and investor coalitions, form an interconnected system using their shareholder influence to press public companies on ESG issues worldwide.
• This ecosystem wields significant power in corporate governance, challenging the old notion that institutional investors are too passive, fragmented, or not transnational enough to trigger change.
• Much of the ESG stewardship activity is collective, via networks, joint initiatives, and shared principles, to overcome individual free-rider limitations and send unified signals on sustainability expectations.
• The coordinated, cross-border nature of this movement is leading to convergence in stewardship standards across markets, from stewardship codes to global investor principles.
• Global ESG norms may clash with local political or regulatory resistance, like policymakers wary of “woke capitalism”, which means some regional variations are still likely to remain.
• Overall, the proactive behaviour of institutional investors shows investors can and do overcome collective-action hurdles and jointly drive companies toward sustainability goals.

This article shows proactive ESG management and transparency is increasingly essential for corporates, as a broad swath of shareholders collectively expect progress on sustainability issues.

Lawmakers need to strike a balance between leveraging this investor-driven momentum through supportive stewardship codes and disclosure regimes and asserting local oversight to ensure alignment with domestic interests.

As a conceptual analysis, the paper does not offer quantitative causal proof but rather a framework for understanding an ongoing governance trend. The ESG stewardship ecosystem is still evolving, and its ultimate impact may vary by region.
