ESG controversies and corporate performance: The moderating effect of governance mechanisms and ESG practices

[Controversies, reputation, and firm value 2/4]

Can strong governance turn a sustainability scandal into firm value?

Ahmed A. Elamer and Mounia Boulhaga examine how governance shapes the financial fallout of controversies in their paper "ESG controversies and corporate performance: The moderating effect of governance mechanisms and ESG practices".

Firm value is measured with Tobin's Q, controversies with the Thomson Reuters ESG controversy score, and the moderators are board independence, board gender diversity, and the overall ESG score.

They analyse 5360 firm-year observations covering 536 listed non-financial companies from the UK, France, Germany, Italy, and Denmark between 2012 and 2021. Their main conclusions include:

• ESG controversies are associated with significantly lower firm value across the sample, confirming markets price them as material operational and reputational risks.
• In firms with more independent boards, controversies weigh less on value, consistent with stronger monitoring, greater transparency, and more credible crisis responses.
• Boards with more female directors (27% of seats on average in the sample) are linked to fewer controversies and to a more measured handling of those that occur.
• Firms with robust internal governance frameworks can convert controversies into reputational and performance gains, in line with the resource-based view laid out in the article.
• UK firms under the market-oriented Anglo-American model respond more dynamically to controversies than firms under the more conservative stakeholder-centred Euro-Continental model.
• Large and well-performing firms absorb controversies far better than small or struggling ones, with 66% of sample firms already operating a dedicated sustainability committee.

This article shows a controversy at a firm with an independent, diverse board and substantive sustainability practices is a different risk event from the same headline at a weakly governed firm.

These results argue against mechanical exclusion, and that recovery is easier using engagement rather than divestment.

The findings also feed the debate on whether ESG scores measure risk or resilience: the informative signal is not the incident itself but the quality of the structures that absorb it.

The sample covers five European countries and a single data provider, so results may not travel to other regions or rating methodologies. Controversy scores also aggregate very different incident types.
