EU Emissions Trading System (ETS): The Carbon Market Guide for Apparel Importers and Philippine Exporters
The European Union Emissions Trading System caps the total greenhouse gas emissions that power generation, energy intensive industry, aviation, and maritime transport may release, then lets those operators buy and sell the right to emit within that cap. It is the world's first and largest carbon market, it sets the price of carbon across Europe, and it is the market that the Carbon Border Adjustment Mechanism is built on. Finished garments are not covered directly, yet every European sourcing team and Philippine exporter already feels the ETS through freight surcharges, energy costs, buyer carbon questionnaires, and the CBAM certificate price. This guide explains the mechanism accurately, then maps the real apparel exposure and the readiness steps that matter.
What the EU Emissions Trading System Is and How It Works
The EU ETS is a cap and trade system established by Directive 2003/87/EC and launched in 2005. It sets a single, declining limit on the greenhouse gas emissions of the largest emitters across Europe, issues a tradable allowance for every tonne in that limit, and lets the market find the cheapest place to cut emissions. It operates in all European Union countries plus Iceland, Liechtenstein, and Norway, and it has been linked to the Swiss emissions trading system since 2020.
The First Carbon Market
The EU ETS was the first large greenhouse gas emissions trading scheme in the world and remains among the largest. It now covers roughly forty percent of the European Union's total greenhouse gas emissions.
- Established by Directive 2003/87/EC
- Operates in all EU countries plus Iceland, Liechtenstein, and Norway
- Linked to the Swiss emissions trading system since 2020
Cap and Trade in One Sentence
The cap is the total emissions allowed. One allowance grants the right to emit one tonne of carbon dioxide equivalent. Operators must surrender enough allowances to cover what they emit, and the cap falls every year.
- Fewer allowances each year means a rising cost to emit
- Trading lets reductions happen where they are cheapest
- Heavy emitters can still operate by buying allowances
A Price That Follows the Polluter
The system applies the polluter pays principle. Every tonne above the cap must be paid for, so emissions carry a cost, and the auction revenue is spent on the clean transition.
- A uniform carbon price across the covered sectors
- Auction revenue funds climate and energy projects
- A market signal that rewards early decarbonisation
What the System Covers
The main system covers electricity and heat generation, energy intensive manufacturing, aviation inside the European Economic Area, and maritime transport from 2024.
- Power and heat plants, refineries, steel, cement, and chemicals
- Flights between airports in the EEA and to Switzerland and the UK
- Ships of 5,000 gross tonnage and above calling at EEA ports
Who Must Comply
Operators of covered installations, aircraft operators, and shipping companies hold a Union Registry account. They monitor their emissions, have the figures verified, and surrender allowances to match.
- Verified emissions report due by 31 March each year
- Allowances to be surrendered by 30 September
- A EUR 100 penalty per tonne of excess emissions, indexed over time
How It Links to CBAM
The Carbon Border Adjustment Mechanism is the border arm of the same carbon price. It charges imports for their embedded emissions so that goods made outside the European Union carry a cost comparable to goods made under the ETS.
- CBAM certificate prices are anchored to EU ETS auction prices
- Free allocation for CBAM goods is phased out from 2026 to 2034
- Both instruments move on the same timetable
How Cap and Trade Works, Step by Step
Every element of the system exists to make one number fall: the total emissions inside the cap. The cap is set in law, reduced each year by a fixed factor, and enforced through a compliance cycle that runs from monitoring to verified reporting to the surrender of allowances.
| Element | How it works |
|---|---|
| The cap | The cap is the total quantity of greenhouse gases the covered sectors may emit in a period. It declines annually by the linear reduction factor so that total emissions fall on a predictable path. |
| The allowance | A European Union Allowance is the right to emit one tonne of carbon dioxide equivalent. Allowances are tradable, so an operator that emits less than its allocation can sell, and an operator that emits more must buy. |
| Distribution | Most allowances are auctioned by member states. A share is allocated for free to sectors exposed to carbon leakage, and that free allocation is being reduced and made conditional on decarbonisation effort. |
| Monitoring and reporting | Each covered operator monitors its emissions and prepares an annual report. The report is checked by an accredited verifier and submitted to the competent authority by 31 March of the following year. |
| Surrender | By 30 September each year, an operator surrenders allowances equal to its verified emissions for the previous year. Surrendered allowances are cancelled, so they cannot be reused. |
| Enforcement | An operator that fails to surrender enough allowances pays an excess emissions penalty of EUR 100 per tonne, adjusted with European inflation, and still has to buy and surrender the missing allowances. |
| Market Stability Reserve | The reserve automatically absorbs surplus allowances in the market and releases them when supply is tight. It keeps the carbon price stable enough to drive long term investment decisions. |
The Four Trading Phases and the Next One
The EU ETS has run in phases. Each phase tightened the cap, widened the scope, and moved the system from a pilot into the central climate instrument of the European Union. The current phase runs to 2030, and the design of the next phase is being negotiated through the review that began in 2026.
Phase 1, the Pilot
The first trading period tested the architecture with power and industry, capped carbon dioxide, and mostly handed out allowances for free. It produced the first carbon price and the first lessons on over allocation.
CompletePhase 2, a Tighter Cap
The second period set a genuinely binding cap, cut free allocation, brought in more auctioning, and saw the price move from near zero to a meaningful level before the financial crisis pressed it down again.
CompletePhase 3, One EU Cap
The third period replaced national caps with a single European Union cap, expanded auctioning, added more gases and sectors, brought aviation in for flights within the European Economic Area, and introduced the Market Stability Reserve.
CompletePhase 4, Current
The current period raises ambition to a 62 percent cut by 2030, lifts the annual reduction factor to 4.3 percent and then 4.4 percent, adds maritime transport, links free allocation to decarbonisation, and pairs with the Carbon Border Adjustment Mechanism.
CurrentPhase 5, Being Shaped
The next period is under review. A Commission proposal from July 2026 would slow the cap decline after 2030 and extend free allocation for onshore decarbonisation, with a political target of agreeing the reform in the first quarter of 2027.
PlannedEU ETS Timeline and the Dates That Matter
These are the dates that shape the carbon cost of European production and of imports into Europe. The near term matters most for sourcing teams, especially the CBAM phase in that runs alongside the ETS free allocation phase out.
| Year | Milestone | Status |
|---|---|---|
| 2005 | The EU ETS launches and the first trading period begins with power and industry. | Complete |
| 2012 | Aviation is brought into the EU ETS for flights within the European Economic Area. | Complete |
| 2019 | The Market Stability Reserve becomes operational to balance allowance supply. | Complete |
| 2024 | Maritime transport joins the system. The annual reduction factor rises to 4.3 percent and a one off cut of 90 million allowances is applied. | Complete |
| 2026 | The CBAM definitive regime begins. Free allocation for CBAM goods starts to phase out, aviation free allocation ends, and international shipping faces its first full surrender obligation. The 2030 cap receives a second one off cut of 27 million allowances. | Now |
| 2027 | Auctions of ETS2 allowances begin, giving member states early revenue ahead of the system start. The first CBAM annual declaration, covering 2026 imports, is due. | Planned |
| 2028 | ETS2 becomes fully operational for buildings, road transport, and small industry. The annual reduction factor rises to 4.4 percent. | Planned |
| 2030 | Targets fall due: a 62 percent cut in ETS sectors and a 42 percent cut in ETS2, both against 2005. | Planned |
| 2034 | Free allocation for CBAM goods reaches zero, so the carbon border price fully replaces the free allocation those sectors once received. | Planned |
| 2040 | The European Union has adopted a net 90 percent reduction target for 2040 against 1990, which frames the next phase of the carbon market. | Planned |
What Is Covered, and What the Separate ETS2 Adds
From 2028 the European Union will run two carbon markets side by side. The main system continues to cover large point source emitters. ETS2 places a carbon price on fuels used in buildings, road transport, and small industry, which together were not covered by the main system.
EU ETS 1: Large Emitters
- Electricity and heat generation, the largest single source of covered emissions.
- Energy intensive industry such as refineries, steel, cement, lime, aluminium, chemicals, and paper.
- Aviation for flights within the European Economic Area and to Switzerland and the United Kingdom.
- Maritime transport from 2024 for ships of 5,000 gross tonnage and above, covering all emissions on intra EEA voyages and half of the emissions on voyages in or out of the EEA.
- Ship surrender obligations phase in at 40 percent for 2024, 70 percent for 2025, and 100 percent from 2026, with methane and nitrous oxide added from 2026.
ETS2: Buildings, Road Transport, Small Industry
- ETS2 regulates fuel suppliers rather than end users, so the obligation sits upstream at the point where fuels are released for consumption.
- Monitoring and reporting began in 2025. Verified reports are required from 2026.
- Auctions begin in January 2027. The system becomes fully operational in 2028, postponed from 2027 by the 2040 climate law agreement.
- ETS2 is set to cut covered emissions by 42 percent by 2030 against 2005.
- A price stability mechanism releases extra allowances if the ETS2 price climbs above EUR 45 per tonne, and the Social Climate Fund supports vulnerable households.
Finished garments and textiles are not covered by either system
Neither the main EU ETS nor ETS2 places a direct obligation on clothing. The ETS regulates installations and fuel suppliers, not products. The exposure for apparel sourcing is indirect: the carbon cost carried by freight, energy, and the wider European supply chain, and the data demands that follow from the CBAM framework. Any future decision to bring textiles into CBAM would be taken through the scope review, not through the ETS itself.
How the Carbon Price Is Set and Why It Moves
The allowance price is discovered by the market. It reflects the tightness of the cap, the pace of emissions reductions, energy prices, policy expectations, and the activity of the Market Stability Reserve. That single price then flows into electricity bills, industrial costs, freight surcharges, and the CBAM certificate price.
The Market Stability Reserve steadies the price
When the market holds too many allowances, the reserve absorbs them. When supply is tight, it releases them. In 2024 the reserve absorbed 271 million surplus allowances and its holdings were reduced to the 400 million ceiling. The mechanism is designed to keep the carbon price stable enough for a factory or a shipping line to make a fifteen year investment decision, while still rising over time to meet the climate target.
EU ETS and CBAM: How the Two Fit Together
The two instruments solve one problem from two directions. The ETS caps emissions inside the European Union. CBAM places a comparable carbon cost on the embedded emissions of certain imports so that production does not simply move to where carbon is free.
EU ETS
- Caps total emissions and prices every tonne emitted by covered installations, aircraft operators, and shipping companies.
- The compliance obligation sits with the operator inside Europe.
- Allowances are auctioned and traded, and the auction price is the reference carbon price.
- Free allocation is being reduced and tied to decarbonisation effort.
CBAM
- Places a carbon cost on the embedded emissions of certain carbon intensive goods imported into the European Union.
- The obligation sits with the authorised CBAM declarant in the importing member state.
- CBAM certificate prices are anchored to the EU ETS auction price, so the two markets move together.
- Free allocation for CBAM goods is phased out from 2026 and reaches zero in 2034, in step with the border mechanism.
What the EU ETS Means for Apparel Sourcing
A finished shirt does not carry an EU ETS obligation. The carbon market still reaches apparel sourcing through the cost of moving goods, the cost of energy in Europe, the carbon questionnaires that buyers now send, and the price benchmark that a future textile CBAM would use. Understanding the channels is what turns a distant policy into a procurement variable.
Maritime Freight Surcharges
Container lines calling at European ports must surrender allowances for their ships, and they pass that cost to shippers as an emissions surcharge on EU bound freight.
- Ships of 5,000 gross tonnage and above are in scope
- All intra EEA emissions and half of extra EEA emissions are covered
- Surrender reaches 100 percent from 2026
Energy Cost Pass Through
The ETS raises the cost of electricity and heat for European distribution centres, warehouses, and retail. That cost is spread across the landed price of goods sitting inside Europe.
- Power generation is the largest covered sector
- Industrial energy costs flow into logistics and storage
- European buyers price carbon into procurement
Buyer Carbon Questionnaires
European sourcing teams already ask suppliers for energy use, factory emissions, and product carbon data. Those requests grow as buyers report their own emissions and prepare for the CBAM framework.
- Facility level energy and emissions data
- Methodology and calculation records
- A route to verified figures over time
The CBAM Price Link
If textiles are ever brought into CBAM, the carbon price applied at the border would follow the EU ETS auction price. Building measurement now is the cheapest way to be ready for that decision.
- CBAM certificate prices track ETS auctions
- The scope review is the route for any textile inclusion
- Verified data avoids the default value mark up
Carbon Cost in Quotes
Freight surcharges and energy linked costs quietly change a landed price. A sourcing plan that models carbon separately from unit cost keeps margin visible when the allowance price moves.
- Model freight carbon as its own line
- Track the allowance price as a planning input
- Price in the direction the cap is moving
Factory Level Readiness
A factory that can measure its energy use per unit is answering a buyer question before it is asked, and is building the record that a future border carbon measure would need.
- Map production lines to energy consumption
- Keep auditable electricity and fuel records
- Prepare a pathway to third party verification
A Carbon Data Readiness Checklist for Exporters
The EU ETS does not ask a Philippine garment factory to buy allowances. It does reward the factory that can answer a carbon question with a number and a document trail. These are the steps that turn that capability into a commercial advantage with European buyers.
Map each product to its customs code
Classify every line accurately. Line level tariff classification is the control that keeps a shipment compliant and tells a buyer whether any component, such as loose hardware, falls under a separate carbon rule.
Meter energy use at the production site
Measure electricity, fuel, and steam at the level where a per unit figure can be derived. A number a buyer can use is worth more than a policy statement.
Keep auditable records
Retain invoices, meter logs, and calculation worksheets that show how an emissions figure was derived. Verification depends on a document trail, not a single number.
Separate freight carbon from unit cost
Show the maritime emissions surcharge as its own line in a quotation. When the allowance price moves, the buyer can see exactly what changed and why.
Prepare for third party verification
Identify an accredited verifier pathway and align internal records with a recognised monitoring methodology so verified data can replace an estimate on request.
Track the CBAM scope review
Follow the review that could add new sectors. A ready data pipeline turns a future textile phase into an opportunity rather than a last minute retrofit.

Frequently Asked Questions About the EU Emissions Trading System
Direct answers to the questions European sourcing teams and Philippine exporters ask most often about the EU ETS, its scope, its carbon price, and its relationship to apparel.
Does the EU ETS apply directly to clothing and textiles?
No. The EU ETS regulates the operators of large installations, aircraft operators, and shipping companies, not products. It does not place an obligation on a garment or on the importer of a garment. The exposure for apparel is indirect, through the carbon cost carried by maritime freight, the energy used in European distribution, and the carbon data that buyers request from suppliers.
How is the EU ETS different from CBAM?
The EU ETS caps emissions inside the European Union and prices every tonne emitted by covered operators. CBAM places a comparable carbon cost on the embedded emissions of certain goods imported into the European Union, so that production does not simply move to a jurisdiction with no carbon price. The two are linked: CBAM certificate prices are anchored to EU ETS auction prices, and free allocation for CBAM goods is phased out from 2026 to 2034 in step with the border mechanism.
How much does an EU allowance cost?
The price is set by the market and moves daily. Through late 2026 the benchmark allowance traded around EUR 80 to 85 per tonne of carbon dioxide equivalent, having ranged from roughly EUR 50 to a high of EUR 105.73 since 2021. The price reflects the tightness of the cap, energy prices, policy expectations, and the activity of the Market Stability Reserve. Treat any quoted figure as a point in time, not a fixed rate.
What is ETS2 and when does it start?
ETS2 is a separate emissions trading system for fuels used in buildings, road transport, and small industry that are not covered by the main EU ETS. It regulates fuel suppliers rather than end users. Monitoring and reporting began in 2025, verified reporting is required from 2026, auctions begin in January 2027, and the system becomes fully operational in 2028, postponed by one year from the original 2027 start. ETS2 is set to cut covered emissions by 42 percent by 2030 against 2005.
Is maritime shipping covered by the EU ETS?
Yes. Maritime transport joined the EU ETS from 2024. Ships of 5,000 gross tonnage and above calling at European Economic Area ports are covered, with all emissions on intra EEA voyages and half of the emissions on voyages in or out of the EEA. Shipping companies surrender allowances for 40 percent of their 2024 emissions, 70 percent for 2025, and 100 percent from 2026, with methane and nitrous oxide added from 2026. Container lines pass this cost to shippers as an emissions surcharge.
Do Philippine apparel exporters have any EU ETS obligation?
No. A Philippine factory exporting garments does not hold an EU ETS account and does not buy allowances. The obligation sits with operators inside Europe and with the importing declarant for the separate CBAM system. What a Philippine exporter should do is build the carbon data capability that European buyers already request, because that data answers today's questionnaires and positions the factory for any future border carbon measure.
Will the EU ETS change in the coming years?
Yes. The system is under review. In July 2026 the European Commission proposed a package that would slow the annual cap decline after 2030 and extend free allocation for companies that invest in decarbonisation inside Europe, with a political target of agreeing the reform in the first quarter of 2027. Separately, the European Union has adopted a net 90 percent reduction target for 2040 against 1990, which frames the next phase of the carbon market. The direction of travel remains a tighter cap and a higher carbon price over time.
