One Report, One Standard: Why Ghana's Stock Exchange Must Move From Guidance to Mandate

Every year, listed companies in Thailand file a single, consolidated document with their securities regulator called the 56-1 One Report. It merges what used to be two separate filings — business and financial disclosure, and shareholder reporting — into one document that also carries a full environmental, social and governance (ESG) section, built on the Global Reporting Initiative framework and increasingly aligned with international sustainability accounting standards. Filing it is not optional, and it is not staggered by how ready a company feels. Every company listed on the Stock Exchange of Thailand must submit it within three months of its fiscal year-end, and regulators are moving toward real financial penalties and public censure for those who fall short.

Ghana has its own version of this idea, and it deserves recognition rather than dismissal. In 2022, the Ghana Stock Exchange launched its ESG Disclosures Guidance Manual, recommending the same Global Reporting Initiative standards that anchor Thailand's system, alongside internationally respected benchmarks such as the IFC Performance Standards and the UN Guiding Principles on Business and Human Rights. On paper, the intention is sound and the framework is credible. In practice, however, the two systems now sit at very different stages of maturity, and the gap between them is instructive for anyone serious about governance reform in Ghana.

A Framework Without Teeth

The most recent industry survey of Ghana Stock Exchange-listed companies found that nearly half were not complying with ESG reporting expectations at all. Among the companies that did report, a large majority relied on disclosures inherited from a foreign parent company rather than producing standalone Ghanaian reporting — meaning that even the compliance figures we do have often reflect capacity built elsewhere, not capacity built here. Compliance also varies sharply by sector: multinational-heavy industries such as beverages, telecommunications and oil and gas report fully, while sectors such as mining and food production lag badly behind.

This is not a failure of design. It is a failure of enforcement architecture. Ghana's guidance manual deliberately tiers companies by market capitalisation, giving smaller listed firms more time and lighter expectations. That is a defensible transitional choice. But three years on, transition cannot remain the permanent state of the system. Guidance that carries no consequence for non-disclosure will always lose out to quarterly earnings pressure and the everyday cost of compliance work.

What Thailand Got Right

Thailand's advantage is not that its companies are more virtuous. It is that its regulator made ESG disclosure structurally inseparable from financial disclosure. Because the One Report folds sustainability data into the same document, timeline and regulatory review as core financial statements, companies cannot treat ESG as a communications afterthought prepared after the "real" annual report is finished. Data owners across finance, human resources, environmental health and safety, legal, and investor relations are required to coordinate from the start of the reporting year, not the final quarter. That operational discipline — not merely the existence of a template is what produces reliable, comparable, year-on-year ESG data.

Thailand's regulator has also shown it will keep raising the bar. Its most recent revisions align disclosure with international sustainability accounting standards and extend into climate-specific reporting covering direct emissions, energy-related emissions, and emissions across a company's wider value chain. Crucially, the regulator has signalled that once the fuller mandate takes effect, it will carry the authority to issue formal orders, financial penalties, and public censure. Disclosure, in other words, is being treated the same way financial misstatement is treated as a matter of market integrity, not goodwill.

The Case for Ghana

None of this is beyond Ghana's reach. The Ghana Stock Exchange has already stated its ambition to move sustainability from a compliance checkbox to a genuine strategic mandate embedded in company DNA, with 2027 set as a marker for that shift. The Bank of Ghana's own sustainable banking principles show that Ghanaian regulators are capable of building sector-specific ESG accountability when they choose to. What is missing is the final structural step Thailand has already taken: folding ESG disclosure into the same mandatory, penalty-backed timeline as financial reporting, rather than leaving it as a parallel, tiered, and largely voluntary exercise.

Three reforms would move Ghana meaningfully closer to Thailand's standard. First, the Ghana Stock Exchange and the Securities and Exchange Commission should set a firm end date for the current tiered, capacity-based approach, converting the guidance manual into a mandatory annexure to the standard annual report, filed on the same statutory timeline. Second, regulators should require standalone disclosure for Ghanaian subsidiaries of multinational companies, closing the loophole that currently allows firms to rely on a parent company's report instead of demonstrating local ESG performance. Third, non-compliance should carry a defined, escalating consequence — beginning with public listing on a non-compliance register, and moving toward the same financial and censure powers Thailand's regulator is now assuming.

None of this requires Ghana to import Thailand's system wholesale. Ghana's own manual already borrows the right international frameworks. What it needs is the political and regulatory will to convert those frameworks from an invitation into an obligation. Thailand's experience shows what that conversion buys a country: comparable, investor-grade data across an entire listed market, a workforce of professionals trained in a single rigorous standard, and a capital market that global investors can trust without having to guess which companies took ESG seriously and which did not.

Ghana's capital market is smaller than Thailand's, but the stakes for governance credibility are, if anything, higher. As African economies compete for capital in a global environment increasingly shaped by ESG-linked investment decisions, a stock exchange that can point to a genuinely enforced, universal disclosure standard — not a well-intentioned guidance document with a 48 percent compliance gap — will be the one that wins investor confidence. The 2027 ambition the Ghana Stock Exchange has already set for itself is the right one. The task now is to give it the same enforcement architecture that has made Thailand's One Report a working national standard rather than an aspiration on paper.
