UK transition finance guidelines go to consultation as City pushes for a global benchmark

The UK has opened consultation on UK transition finance guidelines, a draft playbook designed to unlock capital for heavy-emitting sectors as they move away from fossil fuels. The draft, published today by the Transition Finance Council, co-founded by the City of London and the UK Government, invites feedback from investors, banks and regulators until 19 September.

“High-emitting sectors urgently need finance to decarbonise,” said council chair Lord Alok Sharma, who called the draft “a critical piece” in building an investable UK market that can also set a “global benchmark”.

At the heart of the draft is a simple proposition: if capital is going to flow at scale to transition activities in cement, shipping, transport or agriculture, investors need a common way to judge what’s credible and what isn’t. The voluntary framework sets principles and factors for company-level finance (rather than one-off projects), and is designed to be flexible across asset classes and geographies, including emerging markets.

That emphasis on credibility reflects where global rule-making has landed. Companies raising transition finance are increasingly expected to publish decision-useful transition plans aligned to the UK’s Transition Plan Taskforce approach (see the government-backed framework here) and to disclose climate risks and opportunities under ISSB standards (IFRS S2 overview here). On the investor side, guidance from international alliances has pushed for clearer definitions of “transition” activities and portfolio-level pathways (see a practical primer on transition financing concepts here).

There is money to be mobilised. Global investment in decarbonisation topped the trillion-dollar mark again last year, with clean-power build-out racing ahead while harder-to-abate sectors lag behind. A high-level snapshot of where the money is flowing, power, transport, industry and grids, is available in the latest energy-transition investment trends summary (overview). The UK’s draft aims to narrow that gap by helping lenders and asset owners distinguish credible transition pathways in complex industries from mere re-labelling.

Vanessa Havard-Williams OBE, a senior leader at the council, said too much capital is “on the sidelines” because of uncertainty over what truly counts as transition finance. The draft, she argued, is meant to be “flexible, proportionate and practical”.

For the City, the stakes are commercial as well as climate-driven: a trusted benchmark could help London capture issuance, advisory work and secondary trading linked to transition-labelled loans and bonds. It would also sit alongside the UK’s wider green-finance plumbing, from taxonomy work to supervisory expectations, that is gradually being stitched together (background on the UK’s green finance strategy here).

What happens next: this first consultation runs to 12:00 on 19 September 2025 and focuses on content, structure and usability. A second draft reflecting feedback is due in November, with a final set of guidelines targeted for 2026. Practitioners who want to see how the UK supervisory approach is evolving can also scan the Bank of England/Prudential Regulation climate resources (overview), which increasingly shape how banks and insurers assess transition risk.

If you’re a treasurer or portfolio manager eyeing the transition label, the key practical questions remain the same: is the company’s plan science-aligned, is the capex schedule funded, and are governance and incentives tied to delivery? The council’s draft doesn’t replace those checks but tries to make them easier to compare.
