Carbon Credits Enter Regulated Finance: How the UK Carbon Registry and Archax Are Tokenising a New Asset Class

On 6 May 2026, the UK Carbon Registry announced a partnership with Archax, the FCA-regulated digital asset exchange and custodian, to launch a new regulated note structure that brings institutional investors into the voluntary carbon credit market through tokenised securities. The partnership is the first regulated structure of its kind to integrate verified carbon credits with UK digital securities infrastructure, and it opens a category that has long struggled to attract institutional capital because of an absence of regulatory legibility.

For a sector watching tokenisation move from financial instruments into physical world assets, this is a meaningful development. Carbon credits have historically suffered from opacity, fragmentation and a lack of standardisation that has kept large pools of capital on the sidelines. Tokenisation combined with regulated issuance infrastructure is one mechanism for resolving that.

How the Structure Works

The partnership uses a regulated note structure rather than a token representing the underlying carbon credit directly. Archax provides custody and distribution through its FCA-regulated infrastructure, enabling institutional and professional investors to access the product via established market frameworks. The note is structured in collaboration with GenTwo, issued as a tracker certificate with an ISIN and listed on the SIX Swiss Exchange.

The first issuance is backed by PURE Carbon, a high-impact water conservation and emissions reduction project. Emissions data is captured at source and processed securely before being structured into the note. This approach addresses one of the core criticisms of voluntary carbon markets: the absence of verifiable, auditable data linking the underlying environmental project to the financial instrument.

Why Archax and Why Now

Archax has been building a track record as the UK's most active regulated digital asset custodian for institutional-grade tokenised securities. Its prior transactions include a tokenised UK Gilt purchased by Lloyds Banking Group using tokenised deposits on the Canton Network, and a partnership with Federated Hermes to tokenise UCITS money market funds. The UK Carbon Registry partnership extends this infrastructure into a new asset class.

The timing reflects a broader shift in how institutional capital is approaching the voluntary carbon market. MiCA's implementation across the EU, combined with the FCA's increasingly detailed guidance on digital securities, has created a window in which regulated note structures can give institutional investors carbon exposure within compliance frameworks they already understand.

The Market Context

The voluntary carbon market has been under pressure since investigative reporting in 2023 and 2024 raised questions about the verifiability of credits from several major standards bodies. Institutional appetite never disappeared but became more selective. Structures that offer verifiable emissions data, regulated distribution and secondary market potential are precisely what sophisticated allocators have been waiting for.

For UK institutions with net zero commitments and restrictions on holding unregulated instruments, a tokenised regulated note with an ISIN and exchange listing resolves the compliance barrier cleanly. For carbon project developers, access to institutional capital at regulated market terms is a meaningful improvement on the fragmented over-the-counter market that has historically characterised voluntary carbon trading.
