1. What is COP 31?

The Conference of the Parties ("COP") refers to the supreme decision-making body established under the United Nations Framework Convention on Climate Change ("UNFCCC").1 COP meetings constitute the primary global platform where international climate policies are negotiated and states' obligations in combating climate change are discussed.

COP 31 represents the thirty-first session of this conference and aims to adopt new decisions regarding the reduction of greenhouse gas emissions, climate finance, adaptation policies, and the limitation of global temperature increase.2 The COP process plays a critical role, particularly in the implementation and updating of the targets set under the Paris Agreement.3

2. Legal Nature of COP Processes

COP decisions may not constitute legally binding international treaties in the classical sense; however, they create significant normative impact as "soft law" instruments within international environmental law. In this respect, such decisions, shape national legislation of states, contribute to the interpretation of international obligations, and lay the groundwork for the development of global environmental standards.

In particular, following the adoption of the Paris Agreement, COP processes have gained a more concrete legal framework through states' obligations to determine and update their Nationally Determined Contributions (NDCs).

3. Legal Significance

a. Determination and Development of International Obligations

COP meetings contribute to the expansion of states' commitments in addressing climate change. Decisions adopted within this framework facilitate the dynamic evolution of international environmental law.

b. Impact on National Legislation

Although COP decisions are not directly binding, they encourage states to introduce regulatory measures within their domestic legal systems, in this context, many countries, including Türkiye, are, setting emission reduction targets, drafting climate legislation, and adopting sustainability and carbon-related regulatory frameworks. This demonstrates that COP processes have a strong, albeit indirect, legal impact.

p>c. Implications for Companies and the Private Sector

 

Decisions adopted at COP summits affect not only states but also the private sector.45 In particular, new compliance requirements arise in areas such as carbon markets, sustainable finance, and ESG (Environmental, Social, and Governance) obligations.

d. Climate Litigation and Judicial Processes

In recent years, with the rise of climate litigation, COP decisions and international climate targets have increasingly been referenced by courts. This indicates that COP processes produce not only political but also judicial consequences.

4. Conclusion and Evaluation

COP 31 represents a critical milestone for the continuity of international cooperation in combating climate change. Although COP decisions are not directly binding, they play a significant role in shaping international environmental law, influencing national regulatory frameworks, and increasing regulatory pressure on the private sector.

In this respect, COP processes go beyond traditional instruments of international law and create a multi-layered and dynamic sphere of legal influence.
