The EU ETS Registry

The European Union’s ETS Registry is established pursuant to Directive 2003/87/EC. The registry ensures the meticulous accounting of emission allowances issued within the EU, but can also contain carbon credits. The registry keeps track of the ownership of these allowances and credits, which can only be held in electronic accounts in the registry. Each EU member state manages its own separate section of the EU ETS Registry. In Denmark, the Danish Business Authority manages all Danish accounts in the EU ETS Registry.

The main purpose of the EU ETS Registry is to keep an account of the companies and aircraft operators covered by the EU ETS Directive. The directive was transposed into Danish law by the Danish Emission Allowances Act (Lov om CO2-kvoter), which is administered by the Danish Energy Agency. Further details about this are available on the Danish Energy Agencys emissions trading system.

The EU ETS Registry is technically operated by the European Commission, which places the registry at the disposal of the member states. Further details about the EU ETS Registry are available on the European Commission’s website.

Establishing accounts in the registry

As a general rule, it is possible for any individual or company to set up a personal holding account in the Danish Emission Trading Registry. Further details about fees, documentation requirements, etc., are found under Establishing and updating accounts.

Operator holding accounts and aircraft operator holding accounts

All Danish companies and aircraft operators covered by the Danish Emission Allowances Act must have an operator holding account or an aircraft operator holding account in Denmark’s section of the EU ETS Registry. This account is to be used for registering the specific company’s or aircraft operator’s emission of greenhouse gases, and once a year, the companies and aircraft operators must surrender to the Danish State the number of emission allowances that correspond to their emission of greenhouse gases in the preceding year.

The Danish Energy Agency will automatically inform the Danish Business Authority of which companies and aircraft operators are covered by the Danish Emission Allowances Act. After this, the Danish Business Authority will directly contact the companies and aircraft operators concerning the establishment of an account.

Person holding accounts and trading accounts

Emission allowances and credits can be traded freely. For this reason, the ETS Directive also makes it possible for other individuals or companies wishing to buy or sell emission allowances and credits to create a person holding account or a trading account in the EU ETS Registry. The difference between the two types of account is primarily the transaction delay (see Transaction delay for further details). Further details about fees, documentation requirements, etc., are available under Establishing and updating accounts.
