Your organization is going to keep using AI, and it also wants to take AI's environmental cost seriously. Until now the choices were to ignore that cost or to overclaim about addressing it. R3CKON is the third option: an honest estimate of your usage-phase footprint with stated error bars, environmental certificates retired in response every month, and a record that says exactly what you can claim.
Free tier: estimates for up to 10M billable tokens a month. Email address only, no card. No API? Estimate from a few questions: for yourself or your whole organization.
Free accounts are open; paid tiers are not yet on sale, and the demo console below runs on demonstration data. Footprint figures are modeled estimates with stated 90 percent ranges, not measurements. Claims are activity claims: certificates record the restoration, reduction, and renewable generation you funded, identified by project and vintage. They never assert a neutrality status, and the certificate says exactly what statements it supports.
We count your AI usage from metadata alone: which models, how many tokens, which regions. Your prompts and outputs never reach us; anything content-shaped is rejected at the API boundary.
No one outside the providers can know AI's environmental cost exactly, so we estimate it honestly: a public, versioned methodology turns your usage into water, carbon, and energy figures, each shown with its full range of uncertainty.
Every month, real money goes to work against the conservative end of that estimate (P90): third-party-issued certificates for water restoration, carbon reduction, and renewable energy are retired for your benefit, whole units only.
You receive a certificate naming exactly what was funded and retired (projects, vintages, supplier references), the estimate that sized it, and the precise statements you can publish on the strength of it.
On the left, our best estimate of what your AI usage consumed, stated with its uncertainty because no one can know it exactly. On the right, the projects your subscription funded in response. Two columns, related but never equated, and never blended into one score.
LEFT SIDE OF THE LEDGER
Providers do not disclose enough for anyone to know this exactly. This column is our best estimate of it, built from your token counts, with the error bars kept visible.

A ledger, not an equation. The right side responds to the left. It never equals it, and no claim we support says it does.
RIGHT SIDE OF THE LEDGER
Real money into projects that restore water, reduce carbon, and add renewable generation. The work happens where those projects are, which may be far from your compute, and the certificate says where.
Whole registry instruments, identified by project and vintage on every certificate. Categories never mix: no combined score, no cross-category totals, and RECs are never presented as carbon credits.
The ledger needs token metadata and nothing else. Every path in is designed around one rule: we never accept a credential that could change anything in your account.
npm install @r3ckon/sdk, wrap your client once. Exact cache and reasoning counts, and a failed report can never break your AI calls. Covers OpenAI-compatible gateways such as OpenRouter.Full trade-offs on Connecting usage.
Most integrations are wired in by a coding agent now, so the documentation is written for one. Paste one instruction block into Claude Code or Cursor and it reads the docs, picks the path, and verifies its own work. Install the skill once and every future session already knows how.
Once connected, agents can read the live ledger over MCP: estimates with their ranges, retirement records, and the exact approved claim sentences, so the sustainability copy your agent drafts is the language the record actually supports. Read-only by design; no tool can push usage or change your account.
