A different set of rules.
The same arithmetic, finished.
The construction industry has measured carbon for thirty years. Most of the measurement systems stop counting at the edge of a tree. The Divergent Resource Logic framework, set out in the documents on this site, finishes the count — adds soil carbon, end-of-life methane, and foregone sequestration to the boundary that already exists for steel, concrete, and aluminium. This is the work.
Four doors
The site is organised around four things you can do here. They are listed in the order most readers want them.
The argument in plain language, with the boundary-comparison graphic. Fifteen minutes. Written so a ten-year-old could follow it.
Award-winning buildings recomputed under full-boundary accounting. Their numbers, recomputed. Each page carries a downloadable Reproduction Sheet.
The full DRL Thesis Codex v4.3.0 (136 pages, PDF). The scientific argument with every citation. The work that everything else on this site rests on.
Every major carbon calculator, standard, regulator, and certification scheme in one place. Side by side. So the divergence is visible.
The boundary did not move by accident
Aluminium gets counted to the gram. Steel is counted from extraction to the recycled-content credit at end-of-life. Concrete is counted including carbonation re-uptake. Timber, alone among major construction materials, both starts late — the soil and the standing forest are outside the boundary — and ends early, because most of the end-of-life methane is assumed away.
That asymmetry is documented in the standards themselves: EN 15978, ISO 21930, the Environmental Product Declaration regime that every national repository implements. It is not contested. It is, in the standards' own words, the consequence of methodological choice. The DRL framework does not invent new science. It applies measurements that already exist in one part of the regulatory apparatus — soil organic carbon monitoring, end-of-life methane research, foregone-sequestration counterfactuals — to the part that does not currently use them.
Three things follow from that. First, every recomputed building on this site comes out with a different number than its public disclosure shows. Second, the recomputation is reproducible — every input, every emission factor, every citation is on the site and can be challenged line by line. Third, the disclosure boundary is the policy lever. Move the boundary and the entire materials hierarchy re-ranks. That is the policy ask, in its most general form.

Four documents form the core of the public record. Each is downloadable in full. Each carries its own citations.

Auditor's voice. Auditor's posture.
The voice throughout this site is the voice of a senior environmental auditor delivering an exit memo. It is patient, specific, numerical. It is not indignant. It names configuration; it does not characterise intent. The verbs are disclosed, classified, reported, funded, authored, participated. The verbs the work avoids are concealed, hid, lied, conspired. The configuration is described from the documents that produced it. The reader is trusted to draw their own conclusion.
None of this work was commissioned. It is not funded by an advocacy group, a competing industry, or a law firm. It began as the research file for a separate product-development project and grew into a publication when the underlying gap turned out to be larger than the original research required.
