SL(6)658 – The Carbon Accounting (Wales) (Amendment) Regulations 2025

Procedure: Affirmative

These Regulations form part of a suite of regulations made under the Environment (Wales) Act 2016 (“the 2016 Act”) that are referred to collectively as the Climate Change (Wales) Regulations 2025.

These Regulations amend the Carbon Accounting (Wales) Regulations 2018 (“the principal Regulations”).

Part 2 of the 2016 Act requires the Welsh Ministers to meet greenhouse gas emissions reduction targets.  The targets as set by reference to the “net Welsh emissions account” which is defined in section 33 of the 2016 Act.  The account includes both greenhouse gases directly emitted in Wales and may also include qualifying traded carbon units. A carbon unit is a measurement that describes a reduction of emissions or a removal of emissions from the atmosphere as a result of projects designed to achieve this. A carbon unit generated by a project in country A can be purchased by country B and used by country B to help county B meet their emissions reduction targets. 

Regulation 3 of the principal Regulations defined “carbon unit” for the purposes of Part 2 of the 2016 Act.  Regulation 2 of these Regulations updates that definition. 

As required by section 49 of the 2016 Act the Welsh Ministers have obtained and taken into account, advice from the Committee on Climate Change (“the CCC”) before making these Regulations.
