Across the world, sustainability reporting and ESG (Environmental, Social and Governance) standards are evolving fast as companies, regulators and investors push for transparent, comparable disclosures about climate risks, social impacts, and corporate governance practices. What was once a patchwork of voluntary guidelines is increasingly becoming a structured global movement — with new regulatory frameworks, emerging cross-border adoption and innovative reporting approaches shaping how businesses measure and communicate sustainability performance.
A central driver of this global trend is the International Sustainability Standards Board (ISSB), established under the IFRS Foundation to create unified sustainability reporting standards that can be applied across jurisdictions. The ISSB has issued two core standards, IFRS S1 for general sustainability-related disclosures and IFRS S2 focused on climate-related risks and opportunities, which form a baseline for companies aiming to provide consistent ESG information to investors and stakeholders. These standards are gaining formal or informal acceptance in many parts of the world, helping reduce fragmentation in sustainability reporting frameworks.
Momentum around ISSB adoption is substantial. According to the IFRS Foundation, roughly 39 jurisdictions are now committed to or actively integrating ISSB standards into their regulatory frameworks, covering about 60 % of global GDP and a similar share of greenhouse gas emissions. This includes major financial markets in Europe, Asia and the Americas where disclosures aligned with ISSB are either under development or already mandated for certain companies.
Other regions are also aligning with global standards. For instance, Nepal and the Philippines have publicized plans for ISSB-aligned reporting rules, with reporting expected to begin for the largest companies in the Philippines by 2027. Meanwhile, places like Hong Kong have implemented their own sustainability reporting standards that intersect with international frameworks, and Singapore continues to refine its approach to climate-related reporting, guided by ISSB principles.
In the European Union, sustainability reporting is being reshaped by the Corporate Sustainability Reporting Directive (CSRD) and related European Sustainability Reporting Standards (ESRS), which require large companies to disclose extensive ESG information. As regulators refine these rules, the European Securities and Markets Authority (ESMA) has recently supported simplification efforts to make the standards more readable and focused on material ESG issues, while still ensuring that investors receive meaningful sustainability data.
Organizations such as the Global Reporting Initiative (GRI) remain influential, with its standards being among the most widely adopted frameworks guiding ESG performance disclosures by more than 14 000 organizations globally. GRI’s broad scope makes the framework useful for companies reporting on a wide range of environmental and social impacts, complementing more investor-oriented standards like those from the ISSB.
Amid these changes, corporate practice is also shifting. A recent industry report finds that US companies are increasingly investing in digital sustainability solutions to streamline ESG data collection, manage risks, and strengthen business resilience. This trend underscores how sustainability reporting is no longer just a compliance task — it’s becoming a valuable strategy for operational and financial decision-making.
Despite progress, sustainability reporting is still facing complexity and variability across regions. Fragmented regulatory landscapes mean that some companies voluntarily disclose detailed Scope 3 emissions — which include indirect emissions from supply chains — even when not required by regulation, highlighting a broader corporate drive toward transparency.
The push for consistent ESG disclosures has also sparked efforts to harmonize global frameworks. Industry groups and reporting standard providers are increasingly seeking alignment between different systems — such as ISSB, GRI, CSRD and other national or regional standards — to foster comparability and reduce reporting burdens on multinational companies.
The growing adoption of sustainability reporting standards reflects wider stakeholder expectations. Investors, customers and regulators are demanding more detailed and decision-useful ESG information, which in turn is accelerating the integration of sustainability into corporate strategy and financial reporting cycles. As global frameworks continue to mature and align, ESG reporting is poised to become a core part of how companies communicate long-term value and risk management to the world.
