Turkey’s national emissions trading system moved from blueprint to binding law on August 27, 2026, when the Regulation on the Turkey Emissions Trading System was published in the Official Gazette and entered into force. The text, prepared by the Ministry of Environment, Urbanization and Climate Change, fixes the operating rules of what will become the largest new compliance carbon market at the edge of the EU: allocation mechanics, surrender deadlines, offset eligibility, market stability tools and penalty levels. For industrial operators, offset developers and carbon traders watching CBAM-driven carbon pricing spread beyond the EU, the regulation answers most of the design questions that the 2025 Climate Law left open.
What the Regulation Locks In
The core unit is familiar: one allowance represents the right to emit one tonne of CO2 equivalent. The cap, however, is not a fixed absolute number. It will be determined on the basis of emissions intensity and announced through a National Allocation Plan, comprising allowances allocated free of charge plus any volume offered for sale on the primary market. This puts the Turkish design closer to newer Asian systems than to the EU ETS’s predetermined cap trajectory.
Coverage is tiered by size. Installations are divided into three categories by estimated annual emissions: up to 50,000 tonnes of CO2 equivalent (Category A), between 50,000 and 500,000 tonnes (Category B), and above 500,000 tonnes (Category C). Only Category B and C installations carrying out regulated activities will participate in the ETS. Category A sites remain under monitoring, reporting and verification obligations but stay outside the trading system, a choice that keeps small emitters in the data system without imposing compliance costs on them.
Covered operators must obtain a greenhouse gas emissions permit from the Directorate of Climate Change. Permits are valid for five years, with renewal applications due at least six months before expiry. Operators have three years from the Climate Law’s entry into force to secure their permits, and are deemed to hold one on a one-time basis during that window.
Benchmarks, Not Grandfathering
Free allocation will be calculated through a sub-installation-level benchmarking methodology based on product, measurable heat, fuel and production process benchmarks. The free allocation amount combines the relevant benchmark value, a free allocation rate, a sectoral activity factor and the verified activity level, with a cross-sectoral correction factor available if needed. This is a deliberate rejection of pure historical grandfathering: allocation will move with output and performance against benchmarks, not with past emissions.
Compliance timing is now fixed. Operators must surrender allowances matching each installation’s verified emissions through the registry by the last business day of November in the relevant compliance year, and must submit verified emissions and activity data for the preceding calendar year by April 30, verified by an accredited body. Records must be kept for at least ten years. Banking of allowances into future years and limited borrowing from future years are both permitted.
Trading, Stability Tools and a Built-In Price Floor
The market architecture borrows visibly from the EU playbook. Allowances will be auctioned on the primary market according to an auction calendar, secondary trading will run through continuous trading, and a market stability reserve will be established to support price stability by tracking allowance prices and volumes in circulation. The registry itself, covering issuance, holding, transfer, surrender, cancellation and retirement, will be operated by Energy Exchange Istanbul, known internationally as EXIST, with separate accounts for each installation.
The most distinctive feature is the additional allowance reserve. Installations facing an allowance deficit may, under conditions to be set, tap a reserve of up to 10 percent of the ETS cap. The price is designed to sting: allowances from this reserve will cost at least 50 percent above the higher of the weighted average primary-market price or the weighted average secondary spot price over the preceding three months. In effect, the reserve caps scarcity-driven price spikes while guaranteeing that emergency supply is always the most expensive option on the table.
Domestic Offsets and the Linking Option
The regulation opens the door to offsets from day one of design. Carbon credits generated by projects inside Turkey may be used toward surrender obligations up to a rate to be determined by the Carbon Market Board, the body chaired by the environment minister that the 2025 Climate Law created to steer the system. That single decision, the offset usage ceiling, will determine the size of the domestic project pipeline the ETS can absorb, and it is still unwritten.
The text also contemplates international linking: the Turkey ETS may eventually connect with emissions trading systems in other countries or regions, including through mutual recognition of allowances. For a market whose largest trade relationship is with the EU, and whose exporters have been paying the EU Carbon Border Adjustment Mechanism since it entered its definitive phase on January 1, 2026, that clause is the long game. A domestic carbon price credible enough to deduct from CBAM liabilities is the economic rationale behind the entire exercise, a point Carbon Market Watch pressed in its May 2026 assessment of the draft regulation, warning that a weak ETS would fail both the climate and Turkish exporters.
Penalties and the Pilot Runway
Non-compliance is priced in lira. Fines for failing to submit verified emissions reports range from TRY 627,450, about $13,000, for Category A installations up to TRY 6.27 million, about $130,000, for Category C installations emitting more than 2 million tonnes a year, and these penalties double for operators covered by the ETS. Operating without a required emissions permit can cost up to TRY 12.55 million, roughly $260,000. Under the Climate Law, entities that miss surrender obligations also face fines equal to twice the recent allowance price per missing allowance, must make up the shortfall the following year, and risk permit revocation, though administrative penalties are reduced by 80 percent during the pilot phase.
The system will not switch on at full force. A pilot implementation period comes first, with scope, duration and rules set by the Carbon Market Board. Operators included in the pilot must submit their initial Monitoring Methodology Plans electronically within two months of the regulation’s entry into force, a deadline extendable to six months. The first full implementation period after the pilot will consist of two subperiods, with benchmark values for the first subperiod announced in the National Allocation Plan once the relevant verification reports are in. The regulation also formally repeals Turkey’s 2014 MRV regulation, folding a decade of monitoring practice into the new framework.
What It Means for Market Participants
For covered industrials, the message is that free allocation is generous but conditional: it rewards benchmark performance and documented activity, so verified data quality now directly determines allocation size. For project developers, the domestic offset clause creates a new compliance demand channel whose scale hinges entirely on the Carbon Market Board’s usage rate decision. For traders and investors, the pilot phase, the intensity-based cap and the price-floored reserve signal a market engineered for a soft start, with price discovery likely to be muted until auction volumes and the National Allocation Plan give the cap a real number.
What to Watch
Three decisions will determine whether this becomes a real carbon price or a reporting exercise. First, the Carbon Market Board’s offset usage rate, which sets domestic credit demand. Second, the first National Allocation Plan, which will reveal benchmark stringency and how much of the cap, if any, is auctioned rather than given away. Third, the pilot’s scope and duration: a short, broad pilot keeps Turkey on track toward a system the EU might one day recognize for CBAM deduction purposes, while a long, narrow one would confirm the skepticism already voiced by market watchers.
