Sustainability reports are communication documents created to inform internal and external stakeholders about an organization’s economic, environmental, social, and governance performance in relation to its sustainable development goals.
Companies may engage in sustainability reporting for various reasons: to better understand sustainability and climate-related risks and opportunities, to enhance corporate reputation and brand loyalty, to evaluate and benchmark sustainability performance against laws, regulations, norms, performance standards, and voluntary initiatives, to compare performance internally and externally, to comply with national legislation and stock exchange listing requirements, and to identify expectations around sustainable development from both the company and its stakeholders.
Transparent Reporting in Compliance with Standards
All reporting processes are conducted by Metsims Sustainability Consulting, tailored to sector-specific requirements, company needs, economic status, workforce size, export priorities, and stock exchange listings. Reports are prepared in compliance with GRI, TSRS, and CSRD standards.
The Global Reporting Initiative (GRI) is the most widely used sustainability reporting framework worldwide, enabling organizations to transparently disclose their environmental, social, and economic impacts. The updated 2021 GRI Standards have strengthened the sector-specific reporting approach, aiming for more effective disclosure of sector-related impacts.
The Turkish Sustainability Reporting Standards (TSRS), issued by the Public Oversight Accounting and Auditing Standards Authority (KGK), became mandatory in 2024 for companies identified through a decision tree model. While broadly aligned with GRI, TSRS requires third-party assurance and covers elements such as sustainable business models, corporate structure, strategy, sustainability and climate-related risk and opportunity management, targets, and performance indicators.
The Corporate Sustainability Reporting Directive (CSRD) is one of the EU’s most comprehensive regulations making sustainability reporting mandatory and auditable. Gradually enforced from 2024 onward, CSRD applies not only to large EU companies but also to non-EU companies operating within the EU. CSRD-compliant reports must be prepared in accordance with the European Sustainability Reporting Standards (ESRS), following a double materiality assessment and covering high-priority areas such as sustainability governance, climate risks, human rights, and value chain impacts. Like TSRS, CSRD also mandates third-party assurance, enhancing the reliability of disclosures.
