ESG Research in Sustainable Investing

Are we aware that every investment decision — especially when guided by ESG research in sustainable investing — carries not only a financial return, but also a legacy? That what we choose to measure — and what we ignore — determines the companies that flourish, and the ones that fade? Are we conscious of that choice? At Little Square Capital, our Principles and Goals call us to honesty, integrity, and stewardship of shared resources.

Environmental, Social, and Governance (ESG) factors are now a familiar acronym in wealth management. They are part of a broader conversation about accountability, sustainability, and the institutional structures that will define future markets. Firms have built ESG model portfolios for advisors to present to clients. But do these models go far enough?

Are we asking the right questions — about how ESG research is done, who shapes it, and whether it truly serves transformation rather than optics?

Research as the Gatekeeper

Investment research — and particularly ESG research — has always served as the filter between companies and capital. When ESG overlays traditional research, it sharpens this role — but not without bias or blind spots.

Scoring and Ratings: Advisors often rely on ratings agencies. But are these scores really measuring what matters, or just what’s easiest to report?
Detailed ESG Analysis: ESG reports highlight policies and programs, corporate commitments, and challenges. But is there a clear link that connects initiatives to long-term financial resilience, or simply a list of aspirational statements?
Benchmarking: Comparing peers can be useful. But do we really compare like with like, or simply reward those best at disclosure?
ESG-Centric Reports: Advisors receive stacks of branded research. But how much of it is actionable insight or critical analysis, and how much is marketing gloss?
Investment Ideas present “ESG leaders” — but do they reward genuine transformation, or merely compliance with disclosure thresholds?

Are these tools genuinely aligning capital allocation with sustainable change — or do they merely certify the status quo under the guise of virtue?

The Role of ESG Research in Sustainable Investing

ESG research in sustainable investing determines which companies attract capital and which fade from view. But if research itself is flawed, what does that mean for the credibility of the movement?

Meeting the Challenge

The surge of ESG ratings hides a deeper issue: most frameworks still overweight governance and disclosure, arguably because those are easiest to measure or worse, exclude regions where ownership structures are less concentrated or transparency is politically constrained. Very few confront the harder questions of intent or impact. They only score the projections a company claims, but doesn’t track how it acted over time.

Most ESG frameworks overweight governance disclosure, because governance is quantifiable — but sustainability and social transformation are not easily reduced to numbers.

Who decides what counts as meaningful? Who measures whether a company has genuinely transformed its environmental footprint, its treatment of workers, its supply chains? Can we claim progress when the loudest voices are asset managers and ratings agencies, and the quietest belong to communities, contractors, and labourers themselves? Who holds companies accountable when disclosures conflict with real outcomes — like environmental harm, labour abuses, or supply chain violations – or their political donations lobby for support of unequal market structures?

This gap matters for those looking to not only grow wealth, but to align investments with core values. Relying on incomplete ESG metrics risks could lure investors into “greenwashed” positions — portfolios that look ethical on paper but fail to deliver genuine impact in practice.

A Stakeholder-Based Approach

At Little Square Capital, our Principles and Goals emphasise that sustainable investing is grounded in respect for human rights, fair labour practices, environmental stewardship, and anti-corruption.

If ESG research is to align with those principles, it must be built from the ground up integrating viewpoints of all stakeholders in analysis and ratings systems. What if ESG research included more than shareholder reporting? What if it began with a crowd-sourced model of accountability?

To realign ESG research with reality, stakeholder participation must be systemic — not symbolic — ensuring true sustainability accountability across industries. This means defining industry-specific ESG factors, engaging diverse voices, designing transparent scoring, and continuously refining assessments with ongoing stakeholder feedback.

These steps can pave the way for a crowd-sourced ESG scoring and rating system that genuinely echoes the perspectives of all stakeholders, delivering a reliable and transparent assessment of a company’s ESG performance within its specific sector.

Wouldn’t such a system give investors a clearer picture of which companies truly align with their stated values — and which only claim to?

Beyond the Balance Sheet

Sustained monitoring of ESG factors and stakeholder opinions, coupled with adaptable adjustments to scoring and rating systems, remains crucial to ensure relevance and the representation of stakeholder viewpoints. Unfortunately, most ESG risk assessments neglect what lies beyond financial statements, failing to examine a company’s relationships with suppliers, contractors, or the treatment of workers within global supply chains. But real risk lies elsewhere:

In supply chains where forced labour and unsafe conditions persist.
In contractors and subsidiaries who skirt rules that the parent company touts as “core values.”
In tax practices that avoid fair contribution to the societies where profits are made.

Shouldn’t research ask whether companies are confronting these systemic challenges — or merely outsourcing them?

To surmount the hurdles of inequality, a multi-stakeholder approach is indispensable, marked by cooperation between companies, governmental bodies, civil society organisations, and other stakeholders.

The Road Ahead

The struggle for accountability is not new. From early colonial trade codes to modern voluntary standards, each framework promised transparency but often entrenched inequality.

Regulators are tightening ESG rules. Many years ago, Canada’s proposed Bill C-300 sought to make corporate human rights compliance mandatory, not optional. It failed. Since then a myriad of competing standards evolved — ICMM versus IRMA in mining, for example — show how industries fracture under voluntary codes. The result? Investors face a maze of overlapping rules that are too complex for many firms to follow consistently.

Investors tied to pre-packaged ESG solutions may find themselves exposed to this confusion. Meanwhile, clients increasingly demand clarity and transformation — not just a score, but an explanation and evidence of impact.

Sustainability as Discipline, Not Trend

ESG is not a passing fad. It is a discipline — a way of questioning, measuring, and investing that will shape markets for decades. The road ahead underscores the imperative of maintaining robust ESG practices, as failure to do so will strain industries’ access to capital.

The key question is this: do we treat ESG as a checkbox exercise, or as a genuine redefinition of what investment means?

At Little Square Capital, we believe ESG research in sustainable investing should not only reflect numbers but reveal legacies — the structures of power, exclusion, and opportunity that determine which investments are truly sustainable. Sustainability analysis is not a trend but a discipline — a foundation of responsible investment. We see it as part of a wider duty: to research not just performance, but legacy.
