ISS-Corporate Launches ISSB-Aligned Reporting Tool as IFRS Sustainability Rules Gain Global Traction

ISS-Corporate has launched a unified reporting program to help companies address IFRS S1 and IFRS S2 disclosure requirements.
IFRS Sustainability Disclosure Standards are being implemented or referenced as mandatory reporting requirements in 36 jurisdictions.
The solution combines advisory support, carbon accounting, and reporting software as companies face rising investor demand for decision-useful sustainability data.

ISS-Corporate has launched a new sustainability reporting solution aimed at helping companies meet the growing disclosure demands tied to the International Sustainability Standards Board’s IFRS Sustainability Disclosure Standards.

The unified reporting program is designed to support companies working through IFRS S1 and IFRS S2, the two core standards that form the ISSB framework. Together, they create a global baseline for sustainability-related financial disclosures.

For corporate boards, finance teams, and sustainability leaders, the launch comes as ISSB-aligned reporting moves from voluntary preparation into regulated market practice. IFRS Sustainability Disclosure Standards are now being implemented or referenced as mandatory reporting requirements in 36 jurisdictions, though adoption levels vary by market.

That shift is raising the pressure on companies to produce sustainability data that investors can use in capital allocation, risk analysis, and long-term valuation.

A Unified Program for IFRS S1 and IFRS S2

ISS-Corporate’s new solution supports both IFRS S1 and IFRS S2.

IFRS S1 covers overarching requirements for material sustainability-related financial disclosures. IFRS S2 focuses specifically on climate-related disclosures. The two standards are designed to improve consistency, comparability, and reliability across sustainability reporting.

ISS-Corporate said its offering brings together advisory expertise, carbon accounting, and reporting software in one coordinated program. The aim is to help companies move beyond fragmented compliance work and build stronger reporting systems.

That matters as many companies still manage sustainability data across disconnected teams, tools, and reporting cycles. As regulators raise expectations, those gaps can become governance risks. They can also weaken investor confidence in the quality of disclosed information.

For executives, the issue is no longer only whether a company reports sustainability information. The larger question is whether that information can withstand scrutiny from investors, regulators, auditors, and other stakeholders.

Investor-Grade Disclosure Becomes a Governance Priority

ISSB adoption is reshaping the way companies approach sustainability governance.

The standards place sustainability-related risks and opportunities closer to financial reporting. As a result, companies must connect climate and sustainability data with strategy, risk management, metrics, and financial impacts.

This creates new demands for boards and senior management. They need clear oversight of disclosure processes, stronger internal controls, and better coordination between finance, legal, risk, and sustainability teams.

For investors, the appeal is clear. More consistent sustainability disclosures can help compare companies across sectors and regions. They can also improve visibility into transition risk, physical climate risk, and long-term resilience.

“As adoption of the ISSB standards accelerates globally, companies need tools that go beyond minimum requirements and enable enduring resilience. Sustainability reporting plays a critical role in how organizations communicate risk, strategy, and resilience to investors and other stakeholders over time. Our unified IFRS S1 and S2 solution brings together expertise and technology to support high-quality, decision-useful disclosures in a rapidly evolving regulatory environment.”

The comment from Reinhilde Weidacher, Head of Corporate Sustainability Services at ISS-Corporate, reflects a wider shift in the market. Sustainability reporting is becoming a core management function, not a side exercise owned only by ESG teams.

What Executives Should Take Away

For C-suite leaders, the main challenge is readiness. Companies operating across multiple jurisdictions may face different timelines and local rules. However, the direction of travel is increasingly clear.

ISSB-aligned reporting is becoming a central part of global disclosure architecture. Companies that prepare early may be better positioned to manage regulatory risk, respond to investor questions, and strengthen internal decision-making.

The finance implications are also material. Poor disclosure can affect market confidence, access to capital, and investor engagement. Stronger reporting, by contrast, can help companies explain how sustainability risks affect their strategy and financial performance.

ISS-Corporate’s new solution enters the market at a time when disclosure quality is becoming a competitive issue. As more jurisdictions adopt or reference IFRS Sustainability Disclosure Standards, companies will need systems that can support both compliance and strategy.

For global markets, the broader significance is clear. ISSB adoption is pushing sustainability reporting toward a more standardized, investor-focused model. That creates new obligations for companies, but also a clearer path for capital markets to assess climate and sustainability risk at scale.
