Biochar
Research vault for biochar science, production, applications, carbon markets, policy, and industry. Notes synthesize primary literature and registry documents (see Key Sources). Report date context: 2026-09-16. User rule: every data claim should carry an outbound https://… or https://doi.org/… in the note body—not only [[wikilinks]].

Prefer these live pages for markets, registries, and standards; keep claim-level citations inside topic notes (see Key Sources).
How to use this vault
- For numbers from heavily cited papers and reports, the source note is the checked home (index in Key Sources); Quantitative Benchmarks is a cross-source cheat sheet. Add new source notes with
content/templates/Source Note.md. - For Puro, prefer the deep cluster under Carbon Markets Hub — chapters, not stubs.
- Cross-link permanence science (Permanence, Permanence Science for Credits) when reading any methodology note.
- New folders use hub MOCs for empty domains; expand with sources before inventing facts.
- Do not invent papers, DOIs, or market figures beyond Key Sources.
