UK Green Taxonomy

Objective

Directing investments towards sustainable activities aligned with climate objectives. Announced in the Green Finance Strategy (2019; updated 2023)

Description

The proposed UK Green Taxonomy is an instrument within the fields of sustainable finance, green finance, climate governance, and sustainable investment. It was a proposed classification framework designed to define environmentally sustainable economic activities and provide activity-level standards for sustainable finance. The proposed UK Green Taxonomy aimed to support the allocation of capital to sustainable activities, reduce greenwashing, provide a common framework and language for sustainable economic activities, and help investors, businesses, and consumers identify environmentally sustainable activities. Stakeholders involved included, among government institutions, HM Treasury and UK government departments involved in sustainable finance policy; and among advisory bodies, the Green Technical Advisory Group (GTAG) and the Land, Nature and Adapted Systems (LNAS) Advisory Group. Among the key organizations involved were the Green Finance Institute (GTAG Secretariat), financial institutions, asset managers, banks, industry associations, NGOs, academic institutions, regulators, and professional bodies. Consultation respondents identified potential uses for the taxonomy as guiding investment decisions, supporting shareholder engagement, supporting green bonds and other sustainable finance products, supporting sustainability reporting, and supporting broader climate and environmental policies. Following a public consultation conducted between November 2024 and February 2025, the UK government concluded that the UK Green Taxonomy would not be pursued and would not form part of the UK sustainable finance framework.

Green Finance Strategy 2019

The development and abandonment of the British green taxonomy

The UK's green taxonomy is a case in which significant policy design and development work was undertaken before the final decision was made not to implement the instrument. Available documentation shows that this process relied on extensive consultation involving financial institutions, industry representatives, trade associations, NGOs, academics, regulators, and government bodies. The Green Technical Advisory Group (GTAG) played a central role in providing expertise and recommendations throughout the development process. However, the consultation revealed differing views on the added value of a UK taxonomy: while some participants considered it a useful common framework, others questioned its practical advantages compared to existing sustainable finance policies and frameworks already used by market participants.

Chronology of the instrument

2020

The Chancellor has announced plans for a
UK green taxonomy for the first time, with the intention of implementing it.
Initial timelines suggest implementation by 2023.

2021

UK Government established the Green Technical Advisory Group (GTAG) to provide independent advice on the development of a UK Green Taxonomy.

2021 – 2023

GTAG produced a series of advisory reports covering taxonomy design, reporting, governance, interoperability and implementation.

2022

The GTAG publishes its first formal opinion, recommending that
technical selection criteria (TSCs) remain science-based and warning against lobbying activities that could weaken environmental standards.

2023

March: The government reaffirms its commitment to the
taxonomy and promises a consultation in the fall of 2023.

April: The Land, Nature and Adapted Systems (LNAS) Advisory Group was launched following a GTAG recommendation.

October: The consultation promised for autumn 2023 does not materialize
. In February 2024, the Environmental Audit Committee writes to the Treasury to
express its concern that the promised consultations on the UK green taxonomy are "significantly behind schedule" and that deadlines are "slipping".

2024

February: Consultation postponed to the first quarter of 2024. November 14, 2024: The consultation is finally launched.

2025

February: The consultation receives 150 responses. Feedback is mixed, with 55
% expressing neutral or negative opinions on the effectiveness of the taxonomy.

July: HM Treasury publishes its response to the consultation, concluding
that a UK taxonomy "would not be the most effective tool" to
ensure the green transition.

The government announces that it will not pursue the policy, opting instead for other instruments such as the UK Sustainability Reporting Standards (UK SRS) and mandatory transition plans.
