1. Introduction: Carbon Is No Longer Merely an Environmental Issue
In recent years, the concept of the carbon footprint has evolved beyond traditional environmental policies and has become an area that generates direct legal, financial, and strategic consequences for companies. The Paris Agreement and the European Green Deal, as the two most significant instruments developed at the global level in the fight against climate change, together with their secondary legislation, have transformed the measurement, reporting, and management of greenhouse gas emissions arising from corporate activities from a matter of voluntary sustainability practice into a compliance obligation.
In particular, European Union regulations such as the Carbon Border Adjustment Mechanism (CBAM), the Corporate Sustainability Reporting Directive (CSRD), and the Emissions Trading System (EU ETS) have effectively made carbon management a prerequisite for commercial activity for companies operating in Türkiye and trading with the EU. In this context, inaccurate calculation or incomplete reporting of the carbon footprint constitutes not merely an environmental deficiency but also a significant risk area that may give rise to administrative sanctions, contractual liabilities, and commercial losses.
From the perspective of Turkish law, considering the Environmental Law (Law No. 2872), the Regulation on the Monitoring of Greenhouse Gas Emissions dated 17 May 2014 (Official Gazette No. 29003), and emerging sustainability-oriented regulatory trends, companies are increasingly subject to systematic obligations to generate, report, and, where necessary, verify greenhouse gas emission data. These developments demonstrate that carbon data is no longer merely a technical measurement but constitutes a declaration capable of producing legal consequences.
Within this framework, carbon management has become a multidisciplinary field falling not only within the responsibility of sustainability or environmental departments but also directly involving legal, financial, risk management, and senior management functions. When combined with the duty of care and loyalty of board members under Article 369 of the Turkish Commercial Code (Law No. 6102), the obligation of accurate and transparent reporting positions carbon footprint management as an integral component of corporate governance.
Consequently, for modern companies, the carbon footprint is no longer merely an indicator measuring environmental impact but has evolved into a critical legal parameter affecting regulatory compliance, investor relations, access to finance, and the sustainability of international trade.
2. What Is a Carbon Footprint?
A carbon footprint refers to the total amount of greenhouse gases emitted into the atmosphere as a result of an organization’s direct and indirect activities and is typically measured in carbon dioxide equivalent (CO₂e). Today, this concept has gone beyond being merely a technical indicator of environmental impact and has become a parameter that directly affects companies’ legal obligations, financial risks, and position in international trade.
Within the framework of international standards, particularly ISO 14064-1 and the Greenhouse Gas (GHG) Protocol, the carbon footprint is systematically classified and reported. In this context, emissions are examined under three main categories:
Direct emissions (Scope 1): These are emissions arising directly from sources owned or controlled by the company. Production facilities, fuel consumption, company vehicles, and process-related emissions fall within this category. From a legal perspective, these emissions constitute the company’s primary area of responsibility and are subject to direct oversight.
Indirect energy emissions (Scope 2): These are emissions resulting from the generation of purchased energy such as electricity, heat, or steam consumed by the company. This category is of particular importance for companies operating in energy-intensive sectors in terms of costs, carbon taxation, and reporting obligations.
Other indirect emissions (Scope 3): These include all emissions related to the company’s activities but occurring outside its direct control, such as supply chains, logistics, business travel, waste management, and product lifecycle emissions. Scope 3 emissions are increasingly considered an extended area of corporate responsibility, particularly within the framework of EU regulations and ESG criteria.
This tripartite structure demonstrates that the carbon footprint is not limited to internal operations but requires a holistic analysis covering the entire value chain. Indeed, with EU regulations—particularly CBAM and CSRD—companies are increasingly held indirectly accountable not only for their own emissions but also for the carbon performance of their suppliers and business partners.
In light of these developments, the carbon footprint has become for companies:
- A reporting obligation,
- A subject of audit and verification,
- A contractual risk factor, and
- A competitive criterion in international trade.
Therefore, the concept of the carbon footprint should no longer be regarded merely as a technical calculation method but as a legal and strategic instrument that determines companies’ regulatory compliance, investor relations, and market positioning.
3. The Legal Nature of the Carbon Footprint
The carbon footprint has evolved into a declaration that produces legal consequences, is subject to audit, and carries binding characteristics for companies. This transformation is shaped at the intersection of the international climate regime, European Union regulations, and national legislation, placing carbon data at the very center of compliance.
In this context, carbon inventories and greenhouse gas reports prepared by companies are regarded as:
- A reporting obligation before public authorities,
- An indicator of reliability for investors, financial institutions, and business partners, and
- A dataset open to scrutiny within audit and verification processes.
From the perspective of Turkish law, the preparation and reporting of carbon footprint data must be assessed within the framework of the Environmental Law No. 2872, the Regulation on the Monitoring of Greenhouse Gas Emissions dated 17 May 2014 (Official Gazette No. 29003), the Communiqué on the Verification of Greenhouse Gas Emissions and Accreditation of Verifying Bodies dated 25 January 2017 (Official Gazette No. 29959), as well as the evolving body of sustainability legislation.
In this regard:
- Incomplete or inaccurate carbon declarations may be subject to administrative sanctions,
- Misleading reporting may give rise to liability for damages vis-à-vis investors or business partners, and
- Company executives may face breaches of their duty of care and loyalty.
Furthermore, where carbon data is disclosed to the public or included in sustainability reports, such information may also fall within the scope of capital markets law, commercial law, and, in certain cases, unfair competition provisions.
In conclusion, carbon footprint management is not merely a technical calculation process but a multi-layered area of legal risk and compliance for companies.
4. Compliance Process for Companies Operating in Türkiye
Carbon footprint calculation and reporting are no longer merely technical sustainability practices but must be evaluated within a binding legal framework shaped by multilayered international and regional regulations.
With the Paris Agreement, states have undertaken commitments to reduce greenhouse gas emissions within the framework of Nationally Determined Contributions (NDCs), leading indirectly to increased measurement, reporting, and reduction obligations for the private sector. These obligations are reflected in national legislation, thereby becoming effectively binding for companies.
At the European Union level, the European Green Deal has established a comprehensive regulatory regime that extends beyond environmental policy to encompass trade, industrial, and competition law, with the objective of achieving a carbon-neutral economy. Within this framework, CBAM has made the accurate calculation and reporting of carbon emissions a prerequisite for market access, particularly for companies exporting to the EU.
Under CBAM, exporters in certain sectors will be required to report embedded carbon emissions in their products and, in subsequent phases, bear carbon-related costs. This clearly demonstrates that carbon data is not merely an environmental indicator but a direct factor affecting costs, competitiveness, and commercial sustainability for companies in Türkiye.
International standards, particularly ISO 14064-1, provide the technical infrastructure enabling the implementation of these regulations and require companies to prepare their carbon inventories in a comparable, verifiable, and auditable manner.
From the perspective of Türkiye, although carbon reporting and an emissions trading system have not yet reached the level of comprehensiveness and mandatory application seen in the EU, current trends indicate a rapid and inevitable transformation in this field.
Indeed:
- Türkiye’s ratification of the Paris Agreement,
- The strengthening of national climate policies,
- Ongoing efforts to establish an Emissions Trading System (ETS), and
- Preparations for sustainability and ESG-oriented regulations
collectively suggest that, in the near future, carbon measurement, reporting, and verification will become mandatory and subject to audit for companies.
Within this framework, the fundamental legal reality for Turkish companies is that carbon footprint management is no longer solely a concern for companies trading with the EU but constitutes a compliance area requiring preparedness across all sectors.
In particular, the following risks are becoming increasingly visible:
- Commercial restrictions due to inadequate carbon reporting in access to EU markets,
- Administrative sanctions arising from non-compliance with forthcoming national regulations,
- Contractual liability and compensation risks due to inaccurate or incomplete carbon data, and
- Reputational damage and loss of access to financing in the eyes of investors and financial institutions.
In conclusion, international and regional regulations have transformed the carbon footprint into a strategic compliance obligation for companies. For companies operating in Türkiye, proactively adapting to this transformation is of critical importance both in minimizing legal risks and in maintaining competitive advantage.
