Türkiye's Ministry of Environment, Urbanization and Climate Change published the Türkiye Emissions Trading System Regulation (Türkiye Emisyon Ticaret Sistemi Yönetmeliği) in Official Gazette No. 33353 on August 27, 2026, effective immediately. The regulation sets detailed requirements for greenhouse-gas monitoring, reporting and verification (MRV) and ETS operation.
Its legal basis is Climate Law (İklim Kanunu) No. 7552, enacted July 2, 2025, and Article 792/D of Presidential Decree No. 4. About 13 months elapsed between the Climate Law and publication of its implementing regulation. The Climate Change Directorate (İklim Değişikliği Başkanlığı) administers the system.
Market design: an auction-centred primary market
The definitions in Article 4 define the primary market (Birincil piyasa) as the market in which allowances (tahsisat) are allocated to participants by auction. By placing auctions, rather than free allocation, in the definition of the primary market, the regulation points to an EU ETS-like auction-centred model.
Emissions-data granularity: the "sub-installation" unit
The operationally demanding issue is likely to be emissions attribution. The regulation defines a sub-installation (Alt tesis) as a technical unit whose boundaries are set through mass-and-energy balances, allocating GHG emissions from activities at an installation to a particular product, production process, or measurable heat or fuel use.
Installations therefore must separate emissions by product or process rather than report a single total. That capability directly supports systems such as CBAM that require product-level embedded emissions; without it, compliance with either domestic ETS requirements or CBAM becomes difficult.
TÜRKAK accreditation is mandatory for verifiers
Article 4 defines accreditation (Akreditasyon) as the assessment, approval, and periodic audit by the Turkish Accreditation Agency (Türk Akreditasyon Kurumu: TÜRKAK), using recognised technical standards, of verification bodies that conduct verification activities. A verifier cannot perform MRV work without that accreditation.
Effective date and basis
Published in Official Gazette No. 33353 on August 27, 2026 and effective immediately; based on Climate Law No. 7552.
Primary market
Defined as a market allocating allowances by auction, suggesting an EU ETS-style auction-centred model.
Emissions granularity
Emissions are attributed by product, process, heat use and fuel use at sub-installation level, consistent with EU ETS Phase 4 methodology.
Verification
Verification bodies require TÜRKAK accreditation and cannot perform MRV work without it.
Exclusions
R&D and testing facilities, biomass-only facilities, and military-related facilities are excluded.
Article 2(2) expressly excludes R&D facilities for developing or testing new products or processes, facilities or areas using only biomass, and military-related facilities.
Positioning as a CBAM-exposed country
Türkiye is a major exporter to the EU of products including steel and aluminium and is directly exposed to CBAM. Because CBAM can deduct a carbon price already paid in the exporting country, the presence of a functioning domestic carbon-pricing system affects exporters' effective burden.
Verification arrangements and data granularity matter here. A deduction requires emissions data to be appropriately verified and reported; merely having a system is insufficient. Türkiye's requirements for TÜRKAK accreditation and sub-installation-level attribution can be read as design choices responsive to that standard.
For procurement teams, the question is not just whether a supplier country has a potentially deductible carbon-price system, but whether its MRV detail and verifier-accreditation framework can meet EU expectations.
