Increasing global risks and regulations are transforming sustainability reporting from a voluntary practice into a strategic governance tool for companies. Reporting in line with international standards and EU regulations is becoming a fundamental element of risk management, access to finance, and long-term value creation. This process enables companies to reshape their decision-making mechanisms with a sustainability focus, while creating a more measurable and transparent structure through digitalization and assurance practices.
Increasing environmental, social, and economic uncertainties make it mandatory for companies to report their financial performance along with their non-financial impacts. In this process, while the importance of long-term value creation capacity increases, integrating the sustainability strategy into the company strategy becomes critical for firms. Sustainability reporting enables companies to present their approaches in this field to the information of their stakeholders. Sustainability reporting, which ensures that non-financial performance is visible in a systematic, comparable, and verifiable manner, also plays an active role in decision-making processes in areas such as risk management, compliance, investor relations, and stakeholder communication. For all these reasons, it holds an important place in terms of corporate governance. This article aims to address the importance of sustainability-oriented transformation for companies, the role and effects of reporting in this process, and current developments in this field.
Sustainability-oriented transformation
Climate change, depleting natural resources, and rising social inequalities are increasing economic, social, and environmental risks, leading the global economy through a structural transformation process. The sustainability-oriented transformation approach, which suggests reconsidering the concept of economic growth in harmony with nature's limits and social welfare, underscores that strategic priorities, decision-making mechanisms, and business models need to be reviewed in conjunction with energy transition and the transformation of production technologies. In this context, elements such as climate change, energy supply security, geopolitical uncertainties, supply chain disruptions, and talent management are becoming as important as financial fluctuations for the current and future performance of companies. Therefore, companies need to increase their sustainability-oriented transformation capacity. Proactively analyzing economic, social, and environmental risks, setting targets by addressing corporate strategy with this approach, and moving to implementation are among the main steps in this process. Stakeholder communication based on transparency is of great importance in conducting a successful process in the long term.
The role of sustainability reporting in transformation
Sustainability reporting enables companies to plan their transformation processes by presenting their environmental, social, and governance performance with measurable data. Seeing the current situation in areas such as carbon footprint, resource efficiency, and social impact facilitates the determination of strategic goals. While this process makes performance visible, it contributes to early detection of risks, increased corporate awareness, and the integration of sustainability goals into corporate culture. Additionally, transparent reporting facilitates access to finance, lowers capital costs, and supports companies being preferred in global supply chains.
International standards and regulations
Global standards in sustainability reporting allow companies to prepare their reports within a common framework and enable the comparison of data across different countries. The Global Reporting Initiative (GRI), one of the most common frameworks, allows companies to report their environmental, social, and economic impacts in a standard format. The International Sustainability Standards Board (ISSB) under the IFRS Foundation, which strengthens the investor-focused reporting approach, focuses on the disclosure of financial risks and opportunities related to sustainability. The ISSB’s IFRS S1 and IFRS S2 standards support investors' decision-making processes by ensuring that company performance is comparable on a global scale.
The EU's new sustainability reporting regime and its effects on companies
On the other hand, various regulations regarding reporting requirements within the scope of the European Green Deal also affect companies through supply chains. In this context, the Corporate Sustainability Reporting Directive (CSRD) was adopted by the EU in 2022. Additionally, the Corporate Sustainability Due Diligence Directive (CSDDD), which was presented as a draft in 2022, was published in 2024. The European Sustainability Reporting Standards (ESRS), which are one of the main implementation tools of the CSRD—which imposes an obligation on companies of a certain size operating in the EU to identify the environmental and social impacts of their activities and to report and disclose these impacts—were adopted in 2023. Furthermore, there are some delays and simplifications in the processes related to certain regulations implemented by the EU in 2025.
Türkiye sustainability reporting standards
One of the primary challenges for companies in the reporting process is the need to comply with reporting demands from different frameworks. Therefore, the preparation of ESRS by observing the principle of interoperability with ISSB and GRI is an important factor that facilitates the process for companies. Parallel to these global efforts, Turkish Sustainability Reporting Standards (TSRS) have entered into force in Türkiye. With the Board Decisions regarding the implementation taken by the POA (KGK), a sustainability reporting obligation has been introduced for businesses that exceed the thresholds determined by taking into account criteria such as the number of employees, total assets, and net sales revenue. The POA, by adopting the internationally accepted international sustainability reporting standards (S1 and S2) published by the ISSB, named them TSRS 1 “General Requirements for Disclosure of Sustainability-related Financial Information” and TSRS 2 “Climate-related Disclosures” and prepared the relevant legislation. With this development, which shows that Türkiye has established a reporting infrastructure integrated with international standards, sustainability reporting has become a regulatory compliance responsibility beyond a practice based on the principle of voluntariness for companies.
Conclusion
Today, sustainability reporting is a strategic management tool that affects risk management, compliance, and access to finance processes, in addition to presenting past activities to stakeholders. With global and national regulations, reporting is also becoming a critical element for corporate governance. In the coming period, sustainability reports are expected to gain a more data-driven, integrated, and forward-looking structure. Companies that manage this process effectively gain a competitive advantage while also obtaining a significant advantage in strengthening their long-term value creation capacity.
