OTE, a.s., has been managing the Czech Emission Trading Registry under authority of the Ministry of the Environment of the Czech Republic since 2005.

The Registry keeps the accurate accounting of the issue, holding, transfer and cancellation of allowances. Allowances and Kyoto units are held on Party accounts, Operator holding accounts, Aircraft operator holding accounts or Person holding accounts. Pursuant to Act No. 695/2004 Coll., on the Terms of Greenhouse Gas Emission Allowance Trading, as amended, operators of installations holding permits issued by the Ministry of the Environment for emitting greenhouse gases are required to open an account in the Registry. Since January 2012 this obligation has been extended to aircraft operators that are holders of an operation licence issued in the Czech Republic or are under the administration of the Czech Republic in accordance with a list of aircraft operators published by the European Commission. Any natural person or legal entity may open a Person holding account, including an installation or aircraft operator that is already an Operator account holder.

The European Union Emission Trading Scheme (EU ETS) is governed by Directive No. 2003/87/EC, as amended. Since 2008 the European registries have been integrated in the global registry system under the Kyoto Protocol. Pursuant to the Commission Regulation (EU) 920/2010, as amended, each Member State is obligated to use the standardised Union Registry that also functions as the registry under the Kyoto Protocol.
