Rewriting the Rules: How Gulf Investors Are Building Their Own Sustainability Playbook

For the better part of a decade, ESG — environmental, social, and governance — has functioned less like a framework and more like a faith. Western asset managers adopted its language, its metrics, and its moral authority with remarkable speed, packaging sustainability as a universal investment imperative. Arab institutional investors, managing trillions in sovereign and family capital, were expected to follow along.

Many are choosing not to.

Across the Gulf Cooperation Council, a quiet but consequential debate is unfolding. Sophisticated Arab investors — from sovereign wealth funds to university endowments to multigenerational family offices — are scrutinizing the assumptions embedded in conventional ESG scoring, finding them culturally narrow, economically misaligned, and, in some cases, structurally biased against the very industries that built Gulf prosperity. What is emerging in response is not a rejection of responsible investing, but a determined effort to redefine what responsible means on Arab terms.

The Structural Critique

The dissatisfaction runs deeper than optics. Standard ESG methodologies, developed largely by European and American institutions, assign scores based on criteria that reflect Western regulatory environments, Western labor markets, and Western definitions of corporate accountability. For Gulf-based investors with significant exposure to hydrocarbons, sovereign infrastructure, and state-linked enterprises, these frameworks create an immediate structural disadvantage.

Saudi Aramco, for instance — a cornerstone holding for numerous regional portfolios — scores poorly on conventional ESG indices despite operating some of the lowest carbon-intensity oil production in the world and funding substantial domestic social infrastructure. The blunt instrument of carbon-sector exclusion, popular among European pension funds, simply does not translate to portfolios that must balance global competitiveness with national economic mandates.

Beyond energy, Arab investors point to the governance pillar as another area of friction. Conventional ESG governance metrics prize board independence, shareholder activism, and executive compensation transparency — structures that reflect Anglo-American corporate models. Family-controlled conglomerates and sovereign-backed entities, which dominate Arab business culture, score poorly not because they are poorly managed, but because they are managed differently. The framework mistakes difference for deficiency.

Islamic Finance as an Alternative Architecture

Rather than simply critiquing Western ESG, forward-thinking Arab investors are drawing on an existing intellectual tradition: Islamic finance. The principles underlying Shariah-compliant investing — prohibition of exploitative interest, avoidance of harmful industries, emphasis on equitable wealth distribution, and the concept of maslaha (public benefit) — offer a coherent and centuries-old alternative to the ESG construct.

Several Gulf institutions have begun formalizing this overlap. The Accounting and Auditing Organization for Islamic Financial Institutions (AAOIFI) has been working to articulate sustainability standards that incorporate Islamic ethical principles alongside environmental and social considerations. Meanwhile, the Islamic Development Bank has published frameworks that position sustainable development through the lens of maqasid al-Shariah — the higher objectives of Islamic law — which include the preservation of life, intellect, lineage, wealth, and faith.

For Arab investors already operating within Shariah-compliant structures, this is not a theoretical exercise. It is a practical toolkit for evaluating whether an investment genuinely serves human welfare — a test that, proponents argue, is both more demanding and more culturally coherent than a composite ESG score generated by a Western ratings agency.

Gulf Funds Asserting Influence

The most visible pushback is coming from the largest pools of Arab capital. Abu Dhabi's sovereign wealth apparatus, which includes ADIA, Mubadala, and ADQ, has engaged directly with global asset managers on ESG criteria, demanding frameworks that account for energy transition realities rather than energy exclusion mandates. Mubadala, in particular, has positioned itself as an active voice in international sustainability forums, arguing that emerging-market and resource-rich economies require differentiated pathways.

Saudi Arabia's Public Investment Fund has taken a similarly assertive posture. Rather than accepting third-party ESG ratings as a condition of capital deployment, the PIF has embedded its own sustainability criteria into co-investment agreements and fund mandates — effectively using its scale to negotiate the terms of responsible investing rather than simply accepting them. The fund's Vision 2030 alignment, which prioritizes domestic employment, economic diversification, and social development, functions as an alternative impact framework that Western ESG scoring largely ignores.

Qatar Investment Authority has pursued a more integrative approach, engaging with European ESG standards while simultaneously advocating for methodology reform through multilateral channels. QIA's position reflects a broader diplomatic instinct: to work within international systems while reshaping them from the inside.

The American Dimension

For Arab investors with significant US exposure — and most major Gulf funds maintain substantial American portfolios — the ESG debate has a distinctly practical dimension. US-listed ESG funds have faced growing political and regulatory scrutiny, with Republican-led states withdrawing pension assets from ESG-focused managers and the Securities and Exchange Commission launching investigations into greenwashing claims. The ESG consensus that seemed unassailable in 2020 has fractured considerably.

For Arab investors, this American ESG backlash is not unwelcome. It creates space for alternative sustainability narratives to gain credibility. If the world's largest capital market is openly questioning whether ESG frameworks deliver on their promises, Arab investors pressing for methodological reform find themselves in more sympathetic company than they did even two years ago.

Some Gulf-based family offices with US operations have begun explicitly marketing their alternative sustainability credentials to American institutional partners — framing Islamic finance principles and development-oriented investment mandates as a more substantive form of responsible capitalism than the checkbox ESG compliance that has drawn criticism from both the political left and right in the United States.

Building a New Vocabulary

What Arab investors are engaged in is ultimately a contest over language — and therefore over power. ESG, as currently constituted, gives Western rating agencies and Western asset managers the authority to define what counts as responsible, what counts as sustainable, and which capital is welcome in the emerging green economy. Arab investors are arguing, with increasing sophistication and coordination, that this authority was never legitimately granted.

The alternative vocabulary they are constructing draws on Islamic ethical philosophy, regional development economics, and a frank acknowledgment that the energy transition must be financed rather than simply demanded. It is a vocabulary that takes sustainability seriously — but refuses to treat it as a Western cultural export.

For Arab investors navigating US markets, the practical implication is clear: engage with ESG frameworks where they create access and credibility, but do not surrender the analytical independence to define what responsible investing means for capital rooted in a different tradition, serving a different set of stakeholders, and operating within a different conception of long-term value.

The West did not invent sustainable capitalism. It merely named it first.
