Turkey Sustainability Reporting Standard (TSRS) 1: A Deep Dive into Sustainability-Related Financial Disclosures

Posted in diğer by econvera on 02/09/2025

The business world is no longer solely focused on profit; it is increasingly accountable for the sustainability of our planet and society. In this new era, a company’s environmental, social, and governance (ESG) performance is scrutinized by investors, customers, and regulators just as closely as its financial results. But how are these two worlds brought together? Enter the Turkey Sustainability Reporting Standard (TSRS) 1, which defines the financial language of sustainability. This article provides an in-depth look at “sustainability-related financial disclosures” under TSRS 1—what they mean, what they encompass, and why they are critically important.

What is TSRS 1 and What Are Sustainability-Related Financial Disclosures?

TSRS 1 is a framework that regulates how companies in Turkey report on their sustainability efforts. At its core are the “sustainability-related financial disclosures.”

So, what exactly are these disclosures?

These disclosures provide information about a reporting entity’s sustainability-related risks and opportunities that could reasonably be expected to affect its:

  • Short-, medium-, or long-term cash flows,
  • Access to finance, or
  • Cost of capital.

They are a specific form of general-purpose financial reporting and also include information about the entity’s governance, strategy, and risk management concerning these sustainability-related risks and opportunities, as well as related metrics and targets.

In simple terms, they provide a financial answer to questions like: “How will climate change impact our operations?”, “How will our social justice policies influence investors?”, or “How could water scarcity disrupt our supply chain?”

Why Are These Disclosures So Important? (The Fundamental Qualitative Characteristics)

TSRS 1 establishes two fundamental qualitative characteristics that make these disclosures “useful”:

  1. Relevance: The information disclosed must be capable of making a difference in the decision-making of the report users (investors, lenders, etc.). Information is relevant if it has predictive value (helps forecast future cash flows) or confirmatory value (confirms or changes past evaluations).
  2. Faithful Representation: The information must be complete, neutral, and free from material error. It is essential to be transparent and honest, avoiding greenwashing. This means accurately reporting both challenges and successes.

These two characteristics are the cornerstone of credible sustainability reporting. Information that lacks these qualities loses its trustworthiness and, consequently, its value.

Enhancing Qualities: 4 Principles for Better Reporting

In addition to the fundamental characteristics, TSRS 1 outlines four enhancing qualitative characteristics that further increase the usefulness of information:

  1. Comparability: Information should be presented consistently, allowing users to analyze changes in an entity’s performance over time and compare it with other entities. This enables investors to make like-for-like comparisons and better investment decisions.
  2. Verifiability: Disclosed information should be capable of being independently checked and verified by an auditor or a third party. This verification significantly enhances the report’s credibility and reliability.
  3. Timeliness: Information must be available to decision-makers in time to be capable of influencing their decisions. Out-of-date sustainability data has little practical value in a fast-moving world.
  4. Understandability: Information should be clear, concise, and presented in a way that is comprehensible to users who have a reasonable knowledge of business and economic activities. Avoiding overly technical jargon is key to accessibility.

What Does a TSRS 1 Report Include?

TSRS 1 is not just about numbers. It requires companies to provide qualitative disclosures across four core content areas:

  • Governance: The processes, controls, and procedures the organization uses to monitor and manage sustainability-related risks and opportunities. This includes the role of the board and management.
  • Strategy: The approach to addressing sustainability-related risks and opportunities that affect the entity’s business model, strategy, and cash flows in the short, medium, and long term.
  • Risk Management: How the entity identifies, assesses, prioritizes, and manages sustainability-related risks.
  • Metrics and Targets: The quantitative and qualitative performance indicators (KPIs) used to measure progress against strategic targets. This includes absolute and intensity metrics (e.g., tons of CO2 emitted, gallons of water used per unit produced) and specific, time-bound targets (e.g., achieve net-zero carbon emissions by 2040, reduce water consumption by 30% by 2030).

Conclusion: The Future of Financial Reporting Starts Today

TSRS 1 places sustainability at the heart of financial reporting, providing companies with a guide for creating long-term value. Investors are now looking not only at a company’s past profits but also at how it manages future risks and adapts to global challenges.

For companies, adopting this standard is not just a compliance exercise; it is a strategic opportunity to:

  • Renew investor confidence,
  • Gain a competitive advantage,
  • Strengthen brand reputation, and
  • Build a more resilient business model.

A sustainable future is built on transparent, accountable, and financially sound decisions. TSRS 1 is a crucial roadmap for this journey.
