UK Emissions Trading Registry

The UK Emissions Trading Registry operates in a similar way to an online bank account. The Registry is a secure web-based application that serves as the UK Emissions Trading Scheme Registry (UK ETS Registry) and, prior to its closure on 1 April 2026, the UK Kyoto Protocol Registry.

The records in the UK ETS Registry include:

• The UK allowances held in Operator Holding Accounts, Aircraft Operator Holding Accounts, Maritime Operator Holding accounts (from 1 July 2026), Trading Accounts and Government Accounts
• the transfer of allowances between these accounts
• the verified emissions and allowances surrendered by operators
• the free allocation of allowances to Operator Holding Accounts and (for the 2021- 2025 scheme years only) Aircraft Operator Holding Accounts

Obtaining a Registry account

Installation operators, aircraft operators and maritime operators (from 1 July 2026) who have been issued with a UK ETS permit or an emissions monitoring plan will have a relevant holding account opened for them by the Registry Administrator.

The Registry Administrator will send the designated contact for the permit or emissions monitoring plan the new account numbers and instructions on how to appoint Authorised Representatives to these accounts. Note that UK allowances can be delivered into a holding account without Authorised Representatives being added.

Other registered users can make an application to open a UK ETS Trading Account. These account types must have 2 registered users added at the point of application.
