What is the difference between CBAM and the EU ETS?
CBAM is a border adjustment for covered imports; the EU ETS is the cap-and-trade system for covered emissions inside the EU framework.
CBAM vs EU ETS: The EU ETS prices emissions from covered operators through allowances; CBAM extends a related carbon-cost logic to covered imports by requiring emissions reporting and certificates. Sources: EUR-Lex: Carbon Border Adjustment Mechanism; EUR-Lex: EU Emissions Trading System Directive.
The short version
ETS is the underlying cap-and-trade market for covered EU emissions. CBAM is an import mechanism designed to align selected imported goods with EU carbon-cost exposure.

EU Emissions Trading System
- What it is
- The EU ETS is the EU cap-and-trade system for greenhouse-gas emissions from covered sectors.
- Scope
- Covered installations, aviation and maritime activity under the ETS directive and related implementing rules.
- Who it applies to
- Operators and aircraft or shipping entities covered by the ETS framework.
- Key dates
- Created by Directive 2003/87/EC.
- The system has developed through trading phases and later amendments.
- Core obligations
- Monitor and report covered emissions.
- Surrender allowances for verified emissions.
- Comply with permitting, monitoring and registry requirements where applicable.
- Penalties
- The ETS directive includes an excess-emissions penalty for failure to surrender sufficient allowances, alongside Member State penalties for other infringements.
Which applies to you?
If you operate a covered installation, aircraft activity or shipping activity, check ETS. If you import covered goods into the EU, check CBAM.
Frequently asked
Is CBAM part of the EU ETS?
CBAM is separate legislation, but it is designed around EU carbon pricing and the gradual adjustment of free allocation under the ETS.
Who buys CBAM certificates?
Authorised CBAM declarants must surrender certificates for covered imported goods during the definitive period.
Who surrenders ETS allowances?
Covered ETS operators and entities surrender allowances for verified emissions under the ETS framework.
