Important Changes To The Environmental Impact Assessment ("EIA") Regulation In Türkiye

July 2025 – Comprehensive updates have been made to the Turkish EIA Regulation with the regulation published in the Official Gazette dated 26 June 2025. In particular, the project lists (Annex 1 and Annex 2) that determine which projects are subject to the environmental impact process and how they are subject to it have undergone notable changes.

Why are Annex 1 and Annex 2 lists important?

• Projects included in Annex 1 are considered to have high environmental impacts and require the preparation of a detailed "EIA Report." This entails a longer, more detailed, and more costly process for the investor.
• Projects included in Annex 2 are considered to have lower environmental impacts. In such cases, only a "Project Information File" is prepared, and the project is typically subject to a faster evaluation process. If deemed appropriate, the process can be completed more quickly and at a lower cost with a "EIA Not Required" decision.
