Emissions Trading Schemes

From 1st January 2021 following the UK's withdrawal from the European Union, all installations were transferred over to a new UK Emissions Trading Scheme (UK ETS) and under the terms of the Northern Ireland Protocol, Northern Ireland Electricity Generators continue to be participants in the European Union Emissions Trading System (EU ETS).

Participating in the UK ETS

Guidance on participating in the new UK ETS is available on the Government website using the link below.

For both schemes all applications, notifications and forms must still be submitted through the online ETSWAP system.

If you think that your installation may be covered by Schedule 1 of the Regulations, please contact us on 028 9056 9299 or email emissions.trading@daera-ni.gov.uk with your query.

UK Free Allocation Table.

The UK ETS authority has assessed the applications for a free allocation of allowances for the 2021 to 2025 allocation period.

The allocation table has been published by the UK ETS authority: see here.

Participating in the EU ETS: NI Generators

NI Electricity Generators shall remain in EU ETS by virtue of the Ireland / Northern Ireland Protocol

Further information for participating in the EU Scheme is available via guidance from the EU Commission. The EU ETS works on a ‘cap and trade’ basis, so there is a ‘cap’ or limit set on the total greenhouse gas emissions allowed by all participants covered by the System and this cap is converted into tradable emission allowances.

Monitoring, reporting, verification and accreditation

An EU ETS operator must propose a monitoring plan when applying for a greenhouse gas emissions permit. The monitoring plan provides information on how the EU ETS operator’s emissions will be measured and reported. A monitoring plan must be developed in accordance with the European Commission’s Monitoring and Reporting Regulation and be approved by an EU ETS Regulator, in Northern ireland this is the Chief Inspector from the NIEA. The reporting year runs from 1 January to 31 December each year.

The EU ETS requires all annual emissions reports and monitoring to be verified by an independent EU verifier in accordance with the Accreditation and Verification Regulation. A verifier will check for inconsistencies in monitoring with the approved plan and whether the data in the emissions report is complete and reliable.

The European Commission’s Guidance on the Accreditation and Verification Regulation aims to help operators of all stationary installations, verification bodies and regulators perform verifications consistently throughout the EU. It provides practical information and advice on the process and requirements for annual verification required by the EU ETS Directive, the European Commission’s Monitoring and Reporting Regulation and Greenhouse Gas permits/monitoring.
