Türkiye's ETS Regulation Is Published: How Should Operators Prepare Their Monitoring Plans?

Türkiye's Emissions Trading System Regulation was published in the Official Gazette No. 33353 of 27 August 2026 and entered into force the same day. Based on Climate Law No. 7552, the regulation defines how the carbon market will work, from the monitoring, reporting and verification of greenhouse gas emissions to allocation and surrender obligations. The 2014 Regulation on Monitoring Greenhouse Gas Emissions has been repealed.

In this post we summarise the topics operators will deal with most in the coming months.

Which installations are covered?

The regulation divides installations into three categories according to their annual emissions:

• Category A: 50,000 tonnes of CO₂ equivalent per year or less
• Category B: between 50,000 and 500,000 tonnes of CO₂ equivalent
• Category C: more than 500,000 tonnes of CO₂ equivalent

CO₂ from biomass is excluded from the calculation, and the value is determined conservatively on the basis of installed capacity.

The emissions trading system covers Category B and C installations carrying out the activities listed in Annex 1 of the regulation. Staying outside the system, however, does not end monitoring and reporting obligations. Schools, universities and hospitals, for example, are kept outside the ETS, but their monitoring, reporting and verification obligations for Annex 1 activities continue.

The clock is running on monitoring plans

The system starts with a pilot period. Its scope, duration and procedures are determined by the Carbon Market Board.

Operators included in the pilot period must submit their first monitoring methodology plans electronically to the Climate Change Presidency within two months of the regulation's entry into force, that is, by 27 October 2026. The Presidency may extend this deadline by up to six months. For operators not included in the pilot period, the first plan is due by the end of the calendar year before the first compliance period begins.

The monitoring plan is the core document that defines emission sources, source streams such as fuels and raw materials, calculation or measurement methods, data owners and quality control steps. Because every later report relies on this plan, it should reflect the real data flow on site.

The annual cycle: reporting, verification and records

Once the plan is approved, the work becomes an annual cycle:

1. Operators report the previous year's (1 January–31 December) emissions and activity levels by 30 April each year. The Presidency may extend this deadline by up to one month.
2. Emission reports are verified by accredited verification bodies.
3. All relevant data and records must be kept for at least 10 years.

The regulation also sets administrative fines that increase with the installation category, for example when a verified report is not submitted on time. Data should therefore be collected regularly throughout the year, not at year end.

What should operators do now?

• Confirm whether you are within the scope of the pilot period through Carbon Market Board decisions and Presidency announcements.
• Calculate your installation's category on the basis of installed capacity; list Annex 1 activities and emission sources.
• Clarify the source, owner and measurement frequency of fuel, raw material and production data.
• Prepare the monitoring plan together with evidence such as meter, invoice and laboratory records.
• Set up a document structure that supports verification and the 10-year record-keeping obligation.

How can Yörünge Kurumsal help?

Yörünge Kurumsal supports operators with greenhouse gas inventories, monitoring plan preparation, data collection infrastructure and reporting processes. Under the regulation, verification is carried out by accredited verification bodies. Our work therefore focuses on building a data structure that is traceable, consistent and ready for verification.
