Turkey Emissions Trading System (TR ETS): The 2026 CFO Guide to Compliance, Carbon Accounting and Financial Exposure
Turkey has moved from discussing carbon pricing to building an operational emissions trading framework. For finance teams, the question is no longer only how emissions are measured. It is whether a facility falls within TR ETS, what allowances it may receive or need to acquire, how carbon exposure affects budgets and controls, and whether the company can support its regulatory submissions with reliable data.
TR ETS in one minute
Turkey’s Emissions Trading System (TR ETS) is a cap-and-trade framework under which covered facilities must monitor and report greenhouse gas emissions and ultimately surrender allowances corresponding to their verified emissions.
Under the 2026 TR ETS Regulation, the trading system generally covers facilities carrying out activities listed in Annex 1 that fall within Category B or Category C. Category B starts above an estimated annual emissions level of 50,000 tonnes of CO₂ equivalent, while Category C covers facilities above 500,000 tonnes.
For CFOs, this creates a new financial-control problem: emissions data can translate into allowance requirements, cash expenditure, compliance exposure and potentially material financial reporting consequences.
Key TR ETS facts for finance teams
Facilities conducting activities listed in Annex 1 and meeting the relevant emissions classification criteria.
The Climate Change Presidency is central to permitting and implementation, with EPİAŞ operating relevant market and registry infrastructure.
Emissions, activity levels, monitoring methodologies, allowances, reporting deadlines and supporting records.
Some allowances may be allocated free of charge under benchmark-based rules. Free allocation is not automatic.
Yes. Emissions reports must be verified before submission through the prescribed verification framework.
Carbon obligations can affect budgets, internal controls, production economics, working capital and compliance risk.
What is Turkey’s Emissions Trading System?
An emissions trading system converts a regulatory limit on greenhouse gas emissions into tradable units. Under TR ETS, an allowance represents the right to emit one tonne of carbon dioxide equivalent for the relevant period.
A covered company therefore needs to understand two positions at the same time:
| Operational position | Financial position |
|---|---|
| How much verified greenhouse gas did the facility emit? | How many allowances does the company hold or expect to receive? |
| Which activity and installation boundary is relevant? | Will additional allowances need to be purchased? |
| Are activity and emissions data complete and supportable? | What is the expected carbon cost and cash-flow exposure? |
| Has the reporting and verification process been completed? | How should allowances and related obligations be reflected in management reporting and accounting policies? |
TR ETS should not be treated only as an environmental compliance project. Once an allowance has a market value, emissions data becomes financially relevant data.
Is your company covered by TR ETS?
This is the first question a Turkish industrial company or foreign group with operations in Turkey should answer. Size, turnover or corporate form alone does not determine coverage.
A preliminary applicability assessment should consider at least three questions:
Is the facility carrying out an Annex 1 activity?
TR ETS coverage begins with the activities specifically identified in Annex 1 of the Regulation.
What is the facility’s emissions category?
Category A covers installations at or below 50,000 tonnes CO₂e; Category B covers more than 50,000 tonnes and up to 500,000 tonnes; Category C covers more than 500,000 tonnes.
Does an exclusion or special rule apply?
The Regulation contains specific exclusions and special rules, so threshold analysis alone is not sufficient.
TR ETS categories: A, B and C
| Category | Estimated annual emissions | General TR ETS position |
|---|---|---|
| Category A | 50,000 tonnes CO₂e or less | Generally outside the trading-system scope, subject to the Regulation’s monitoring/reporting framework and specific rules. |
| Category B | More than 50,000 and up to 500,000 tonnes CO₂e | Within TR ETS where the facility carries out a covered Annex 1 activity. |
| Category C | More than 500,000 tonnes CO₂e | Within TR ETS where the facility carries out a covered Annex 1 activity. |
In practice, classification should be documented rather than assumed. Finance teams should be able to reconcile the emissions classification with operating data, production data and the underlying monitoring methodology.
Greenhouse gas emissions permits
Covered businesses are required to obtain a greenhouse gas emissions permit from the Climate Change Presidency in order to carry out activities that generate emissions within the TR ETS framework.
A permit is generally valid for five years. Renewal must be initiated before expiry, and certain changes affecting the facility, operator or category must be notified.
This makes permit management a governance issue as well as an environmental issue. Acquisitions, restructurings, production changes and changes in the legal operator of a facility should therefore be incorporated into the company’s TR ETS compliance procedures.
Monitoring, reporting and verification: the data backbone of TR ETS
The core compliance cycle consists of monitoring, reporting and verification — MRV.
Monitoring
The operator prepares and maintains an approved emissions monitoring plan and gathers the underlying activity and calculation data.
Reporting
Covered operators report the previous calendar year’s monitored emissions and activity levels by the statutory reporting deadline.
Verification
The greenhouse gas emissions report must be independently verified before it is submitted to the Presidency.
Under the Regulation, the annual reporting deadline is generally 30 April for emissions and activity levels relating to the preceding calendar year, subject to the possibility of a limited extension by the Presidency.
For the finance function, the key challenge is not simply whether data exists. The challenge is whether data is complete, controlled, traceable and capable of reconciliation.
Why TR ETS requires finance-grade internal controls
Carbon data frequently originates outside the finance department: production systems, energy invoices, fuel records, meter readings, laboratory results and engineering calculations.
But the consequences of incorrect data can ultimately be financial.
| Data / process | Suggested financial control |
|---|---|
| Fuel purchases | Reconcile consumption records to supplier invoices and inventory movements. |
| Energy consumption | Reconcile meter data to utility invoices and operational records. |
| Production volumes | Reconcile reported activity levels to ERP and production reports. |
| Emission factors | Maintain version control, approval evidence and methodology documentation. |
| Allowance balance | Reconcile registry balances to internal accounting and treasury records. |
| Compliance deadlines | Maintain a documented compliance calendar with named control owners. |
This is where a conventional sustainability project becomes a finance transformation project.
How TR ETS allowances work
TR ETS allowances are issued and tracked electronically. They may enter the market through primary-market sales and/or free allocation, depending on the rules applicable to the relevant period.
Allowances can subsequently be traded in the secondary market. Covered businesses must ultimately surrender allowances corresponding to their verified emissions.
Free allocation is not the same as automatic allocation
The Regulation provides for benchmark-based free allocation. The calculation can depend on the relevant sub-installation, benchmark, free-allocation rate, sector activity factor and verified activity level.
Businesses seeking free allocation must apply. Under the Regulation, the application is generally made within 30 days following publication of the National Allocation Plan.
The financial impact of TR ETS
The most important number for many CFOs will eventually be the company’s net carbon position.
A simplified management calculation is:
Verified Emissions − Available Allowances = Net Allowance Requirement
If the company has an allowance deficit, market purchases can create a cash requirement. If a company holds excess allowances, those units may have an economic value subject to the relevant market rules.
Finance teams should therefore consider building TR ETS into:
Model expected allowance requirements using production and emissions scenarios.
Estimate the timing and amount of possible allowance purchases.
Understand how carbon intensity can affect production margins and pricing.
Track emissions exposure alongside traditional financial KPIs.
Determine an appropriate reporting treatment for allowances and related obligations under the applicable framework.
Consider carbon exposure when evaluating facilities, investments and production changes.
Carbon accounting under TR ETS: what should the CFO track?
Regulatory carbon accounting and financial accounting are related but they are not the same thing.
A robust TR ETS finance framework should create a bridge between:
operational emissions data → verified emissions → allowance position → carbon cost → accounting records → management reporting.
At minimum, the finance team should be able to identify:
- allowances received free of charge;
- allowances purchased;
- allowances sold or transferred;
- allowances surrendered;
- year-end allowance balances;
- verified emissions;
- estimated compliance deficits;
- market price assumptions used for budgeting;
- reconciliations between registry and financial records.
The appropriate recognition and measurement approach should be determined by reference to the entity’s applicable financial reporting framework and specific facts. Regulatory compliance data should not automatically be treated as equivalent to a financial accounting conclusion.
TR ETS penalties: why compliance failures can become financially material
The 2026 Regulation provides significant administrative penalties for failures involving emissions reporting and operating without the required emissions permit.
The Regulation includes stated penalty amounts ranging into several million Turkish lira depending on the nature of the breach and the installation’s classification.
More importantly, penalty exposure should not be considered solely as a statutory fine. A compliance failure may also require remedial work, additional allowance surrender, operational attention and management time.
TR ETS records must be retained
Under the Regulation, businesses must retain relevant data and records for at least 10 years.
This reinforces the need for a formal carbon-data governance policy covering document retention, access rights, methodology changes, approval logs and reconciliation evidence.
A spreadsheet owned by a single employee is unlikely to constitute an adequate long-term control environment for a financially significant carbon position.
What happens during the TR ETS pilot period?
The Regulation establishes that TR ETS begins with a pilot implementation period. The detailed scope, duration and implementation rules for that pilot are determined through the Carbon Market Board framework.
This makes 2026 a particularly important readiness period. Companies should avoid waiting for the first allowance invoice or first enforcement issue before building their data and control architecture.
Early preparation gives finance teams time to identify data gaps, assign control ownership, model allowance exposure and understand where environmental reporting intersects with ERP, treasury and accounting processes.

Is your Turkish facility exposed to TR ETS?
Before building a carbon accounting system, determine whether your facility is in scope and where the financial exposure may arise.
SystemsCPA’s TR ETS Applicability & Financial Exposure Assessment is designed for CFOs, finance directors, controllers and international groups seeking a structured first-stage review of their Turkish operations.
The assessment can cover facility classification, regulatory obligations, data readiness, allowance exposure, finance-process implications and the next compliance steps.
Request a TR ETS Assessment →Financial and compliance advisory. Technical emissions verification must be performed through the applicable authorised verification framework.
Who should consider a TR ETS financial readiness review?
A review is particularly relevant where a company:
- operates industrial facilities in Turkey;
- has material greenhouse gas emissions;
- belongs to an international group already managing EU ETS or CBAM exposure;
- expects to receive or purchase emissions allowances;
- uses multiple ERP, production or metering systems;
- has not reconciled environmental data to financial records;
- is preparing budgets or investment plans affected by carbon pricing;
- is acquiring or disposing of an emissions-intensive Turkish facility.
Who does what under a TR ETS compliance model?
| Workstream | Typical responsibility |
|---|---|
| Technical emissions methodology | Environmental / emissions specialists and internal technical teams |
| Independent verification | Authorised and appropriately accredited verification organisations |
| Carbon accounting | Finance, accounting and financial advisory teams |
| Data reconciliation | Finance, operations, IT and sustainability functions |
| Allowance budgeting | CFO, treasury, controlling and management accounting |
| Compliance governance | Management, compliance and designated control owners |
The strongest TR ETS control model is cross-functional: environmental specialists establish the technical emissions basis, while finance ensures that financially relevant carbon data is controlled, reconciled and incorporated into decision-making.
Frequently asked questions about Turkey’s ETS
What is TR ETS?
TR ETS is Turkey’s Emissions Trading System. It is a market-based carbon pricing mechanism under which covered installations monitor verified emissions and surrender emissions allowances.
Which companies are covered by Turkey’s ETS?
Coverage depends primarily on whether a facility conducts an activity listed in Annex 1 of the TR ETS Regulation and its applicable emissions category. Category B and Category C facilities are generally within the trading-system scope, subject to the Regulation’s exclusions and special rules.
What is the TR ETS threshold?
Category B begins above 50,000 tonnes of CO₂ equivalent in estimated annual emissions. Category C begins above 500,000 tonnes. Classification should always be analysed together with Annex 1 activity coverage.
Are TR ETS allowances transferable?
Yes. Allowances are electronically issued, transferable units within the applicable TR ETS registry and market framework.
Can companies receive free TR ETS allowances?
Yes, the Regulation provides for free allocation mechanisms based on factors including benchmarks, activity levels and allocation parameters. Eligible companies must follow the prescribed application process.
When are emissions reported?
The Regulation generally requires businesses carrying out Annex 1 activities to report the previous calendar year’s emissions and activity levels by 30 April, subject to the Presidency’s limited extension authority.
Does the emissions report need to be verified?
Yes. The greenhouse gas emissions report must be verified before submission under the verification framework established by the Regulation.
How long must TR ETS records be retained?
Relevant data and information records must generally be retained for at least 10 years.
Why does TR ETS matter to the CFO?
Because verified emissions can create allowance requirements. These can affect cash flow, budgets, production economics, controls, management reporting and potentially the company’s financial statements.
Can SystemsCPA perform emissions verification?
Independent verification is a regulated activity that must be carried out through the applicable authorised and accredited verification framework. SystemsCPA’s role is focused on financial readiness, carbon accounting, internal controls, data reconciliation and financial exposure analysis.
