SIX doesn't just buy carbon removal. It bought into the company that verifies it.
In one sentence: SIX Group, the operator of the Swiss Exchange and Switzerland/Spain's financial-market infrastructure, is both a buyer of DACCS/biochar removal credits and, since a September 2024 strategic investment, Carbonfuture's lead equity backer, making it the only entity we've reviewed sitting on both sides of the same market; SIX also ships a real, working llms.txt (the file AI assistants read first) and a genuine HackerOne-backed security.txt, ahead of every other company we've reviewed on agent/security discovery.
Relationship, stated plainlyEcoWealth is not affiliated with SIX Group, the Swiss Exchange, SIX Digital Exchange, or Carbonfuture in any way: not a client, listed issuer, or investment counterparty. No contact has been made with SIX Group or Carbonfuture on its behalf. Everything here is independent, unsolicited desk research built from SIX Group's own public pages plus our own earlier, independently-verified research on Carbonfuture (SIX Series A2 investment).
Read this first. Independent research by EcoWealth Corporation. Not requested, produced, reviewed, or endorsed by SIX Group or any named affiliate. Every figure below is drawn from SIX Group's own public pages plus a small set of independently re-verified HTTP checks: no scanning, fuzzing, application, sign-up, or contact anywhere. Staged locally, noindex, not sent to anyone without explicit operator review.
The whole thing, plainly
We read SIX Group's own public pages and found two real credits: a working AI-discovery file most peers don't have, and a genuine buyer-plus-investor stake in the carbon-removal verifier it uses, plus one precise correction on a widely-cited claim. This is independent desk research, not sent to SIX Group and built on no relationship with them. Next: read the four findings below, or jump straight to the brief.
Four facts from the public record
Credit-first: SIX Group's own agent-discovery hygiene and its dual buyer/investor role are both real and independently checkable. One precise correction on a widely-cited claim, one own-target credit.
A real, working llms.txt, rare among the sites we've reviewed
www.six-group.com/llms.txt returns live, hand-written content (governance, sustainability, product-line links), not a fallback page. Paired with a genuine security.txt naming an active HackerOne bug-bounty program with a stated expiry date.
Buyer AND lead investor in the same trust layer
A Feb 2025 multi-year DACCS + biochar removal agreement with Carbonfuture (“securing a portion of its carbon removal needs today, increasing volumes annually”), on top of a September 2024 strategic (Series A2) investment in Carbonfuture itself, confirmed in our own earlier research on Carbonfuture.
Precise correction: SIX itself wasn't a party to the Switzerland-Norway Article 6.2 deal
Carbonfuture (its portfolio company) was one of several named service providers in that pilot (with Neustark, Climeworks, Inherit, Carbon Centric, ClimeFi). SIX's link runs through its investor/buyer relationship with Carbonfuture, one hop removed, not a direct treaty-level signature.
SBTi near-term targets + net zero by 2050
6.8% GHG reduction vs. 2023 (2025 reporting), 100% renewable electricity across Swiss and Spanish locations, verbatim from SIX's own sustainability page.

Relationship framing, four facts, and the one honest EWP concept: everything needed in sixty seconds.
Capability brief
A capital-markets operator vertically integrating into trust infrastructure
Four evidenced findings: SIX's own working llms.txt and security.txt credited plainly, the buyer+investor dual role sourced to SIX's own sustainability page and Carbonfuture's press release, and one precise correction distinguishing SIX's real role from an over-broad claim about the Switzerland-Norway Article 6 deal.
Isn't: a partnership pitch, a proposal, or a claim of affiliation, contract, membership, procurement relationship, or contact with SIX Group or any named partner.
Is: credit-first, evidence-led desk research plus one honest, clearly-labeled EWP intersection concept, never a claim that SIX Group has seen, requested, or endorsed any of it.
An exchange-infrastructure operator that already treats trust infrastructure as an investable asset class is exactly the kind of buyer positioned to recognize what an on-chain work-receipt asset class looks like early. EWP's settle-in-one-transaction design (fund → claim → prove → approve → on-chain settlement) is a smaller-scale version of the same instinct SIX already acted on.
