From Financial Reports to Integrated Sustainability Disclosures: The New Corporate Language of IFRS S1 and S2

From Financial Reports to Integrated Sustainability Disclosures: The New Corporate Language of IFRS S1 and S2

For years, companies measured their performance almost exclusively in financial terms: revenue, margins, and profitability. However, the global context has changed. Today, investors, customers, and regulators want to know not only how much an organization earns, but how it earns it—and at what environmental and social cost.

This pressure to understand not only results but also impacts has led the world to learn a new language. Finance professionals have been forced to consider new indicators and variables, and sustainability experts have had to integrate into business performance.

In this context, the International Sustainability Standards Board (ISSB), part of the IFRS Foundation, published in 2023 two standards that mark a turning point: IFRS S1 and IFRS S2. Both came into effect internationally on January 1, 2024, and represent the decisive step toward a management model in which sustainability is no longer a voluntary report of interest to certain audiences, but strategic, comparable, and verifiable information—establishing a global benchmark for regulators and financial markets.

What Are IFRS S1 and S2 and Why Do They Matter?

IFRS S1 – General Requirements for Sustainability-related Financial Information establishes that companies must disclose information on sustainability risks and opportunities that could affect their financial performance. It is about complying with environmental requirements and demonstrating how the corporate strategy incorporates and manages these risks in an integrated way—from governance to performance measurement—to strengthen long-term value.

For its part, IFRS S2 – Climate-related Disclosures focuses on the financial impacts of climate change. It requires organizations to report on their greenhouse gas emissions (Scopes 1, 2, and 3), as well as disclose their exposure to extreme events, their adaptation plans, and the opportunities derived from the energy transition.

From Voluntary Sustainability to Verifiable Sustainability

Until recently, companies could choose between various reporting frameworks: GRI, SASB, CDP, among others, to disclose their environmental, social, and governance performance. IFRS S1 and S2 do not replace these frameworks, but rather provide a common and global financial language from the sustainability perspective, allowing companies to be compared across countries and sectors.

This shift responds to market demand: investors are demanding standardized and verifiable information in audit processes to evaluate risks and opportunities. It is no longer enough to communicate good deeds or isolated social programs; the company must disclose how ESG factors impact its cash flows, cost of capital, and future growth strategy.

In other words, sustainability is no longer a reputational narrative—it becomes a measurable component of financial performance.

What About Double Materiality?

A key concept in this debate is double materiality. While IFRS S1 and S2 primarily address financial materiality (how environmental, social, and governance factors impact the company’s value), other frameworks such as the European Sustainability Reporting Standards (ESRS) or the Global Reporting Initiative (GRI) also include impact materiality—how a company’s operations affect the planet and people.

The combination of both perspectives (financial and impact) represents the future of corporate transparency. It is not only about protecting the business, but also about ensuring its legitimacy and long-term sustainability.

Opportunities and Challenges for Latin America

In Latin America, several countries are making progress toward embedding sustainability into corporate language. Although progress varies from country to country, the region is improving its adoption processes—recognizing that transparency and comparability are key to attracting investment and strengthening market trust.

Mexico is one of the countries leading the way; the adoption of the new standards is also moving forward strongly. In 2023, the National Banking and Securities Commission (CNBV) published the Sustainability Guide for Issuers, aligned with the principles of the ISSB and the Task Force on Climate-related Financial Disclosures (TCFD). This step laid the foundation for the formal adoption of IFRS S1 and S2, announced in 2024 and to be applied progressively starting in the 2025 fiscal year.

The Mexican Stock Exchange supports this transition by promoting the use of IFRS S1 and S2 as a reference for ESG reporting by listed companies; helping companies prepare for this new stage; encouraging climate transparency; and facilitating access to sustainable finance.

This approach strengthens the regional trend toward greater standard harmonization and demonstrates how sustainability is beginning to be viewed as a factor for competitiveness and a driver of foreign investment.

In Panama, although IFRS S1 and S2 are not yet mandatory, there is already clear momentum toward voluntary adoption as a good practice. Both the Superintendency of Banks and the Institute for Corporate Governance (IGCP) have taken an active role in promoting their progressive implementation through training processes, recognizing their value in strengthening transparency and risk management.

The Latin American Stock Exchange (LATINEX) has positioned itself as a key player in the market’s shift toward ESG criteria. Its promotion of international standards such as IFRS S1 and S2, along with its portfolio of sustainable financial products and training programs, has made LATINEX a catalyst in the responsible investment market. This work strengthens the link between sustainability, corporate governance, and the development of Panama’s capital markets, positioning the country as a regional benchmark in sustainable finance.

A clear example of this momentum is the creation of Panama’s Sustainable Finance Taxonomy, which defines the criteria for identifying green investments and aligns the country with international sustainability frameworks. Together, these initiatives create the conditions for Panamanian companies to anticipate global demands, gain credibility with investors, and boost their competitiveness in a financial environment that is increasingly oriented toward sustainability.

The challenges, however, are real: lack of integrated data, institutional maturity, and technical training. Adopting the new standards will require strengthening information systems, designing control processes, and—above all—building teams that understand both accounting and sustainability languages.

Conclusion: Sustainability as a Competitive Advantage

Moving forward with the adoption of IFRS S1 and S2 is an opportunity to redefine trust between companies, investors, and society. Those who begin today to measure and communicate their ESG performance transparently will be better prepared to compete in a global market that rewards consistency and responsible management.

In the coming years, those who can read (and speak) this new language will be the ones shaping the rules of the market. By integrating sustainability into financial management, companies gain transparency while staying ahead of the future.

The change is already underway. The question is: how soon will you choose to be part of it?
