The Greenhouse Gas Emissions Trading Scheme (Amendment) (No. 2) Order 2025

This Order implements significant changes to the UK Emissions Trading Scheme (UK ETS), primarily splitting the 2026-2030 allocation period into two separate periods: a one-year 2026 allocation period and a four-year 2027-2030 allocation period.

It establishes new processes for free allocation of emissions allowances, modifies eligibility criteria for ultra-small emitters, enhances registry transparency requirements, and expands information sharing powers for climate change policy development.

Arguments For

  • Provides continuity of free allocation for existing participants through 2026 by automatically extending current allocation methodologies, reducing administrative burden

  • Enhances transparency in allowance trading through more detailed public reporting requirements, supporting market integrity

  • Expands information sharing capabilities to support evidence-based climate policy development and assist the Committee on Climate Change

  • Creates more flexible entry points for ultra-small emitters by extending eligibility to installations that began operating between 2021-2024

  • Implements a two-stage application process for 2027-2030 allocation period, allowing operators to adapt to any rule changes between stages

Arguments Against

  • Increases complexity by creating separate allocation periods rather than maintaining a single five-year period

  • May create temporary uncertainty for operators during the transition between allocation periods

  • Requires operators to potentially submit data twice if rules change between application stages

  • Could create administrative challenges for regulators managing different allocation methodologies simultaneously

  • May result in market complications from having different rules apply to different time periods

PART 1 - Preliminary

This Order is made in exercise of the powers conferred by sections 44, 54 and 90(3) of, and Schedule 2 and paragraph 9 of Schedule 3 to, the Climate Change Act 2008.

PART 2 - Free allocation in 2026 allocation period

For installations that benefit from free allocation in the current 2021-2025 allocation period, free allocation in the 2026 allocation period will generally be based on data used to calculate free allocation for the current period without the need for a further application.

PART 3 - Greenhouse Gas Emissions Trading Scheme Order 2020 amended

The UK ETS Order is amended to split the forthcoming 2026-2030 allocation period into a 1-year allocation period covering the 2026 scheme year and a 4-year allocation period covering the 2027-2030 scheme years.

PART 4 - Free Allocation Regulation amended

The process for incumbent installations to apply for free allocation in the 2027-2030 allocation period consists of two stages, to be completed between 1 April-30 June 2025 and 1 April-30 June 2026.

PART 5 - Activity Level Changes Regulation amended

More detailed information about transfers of allowances between accounts in the UK ETS registry is required to be published, and the purposes for which a national authority may disclose information obtained under the UK ETS now include developing policy relating to climate change.
