Standard

EN 16449 — Calculation of biogenic carbon stored in wood

Clause 4. Biogenic CO2 stored = mass of dry wood × carbon fraction (default 0.5) × 44/12. For a dry density of 450 kg/m³ this gives roughly 0.82 t CO2 per m³ of timber. The figure is a stored quantity, not an emission credit; EN 15804 module boundaries must state whether it is reported in A1–A3 and reversed in C3/C4.

How edges in this graph are derivedWI-GRAPH v1.0.0

Species → agent edges come from the WI-SL resistance profile (0–100 ordinal scale derived from EN 350 durability class, extractive chemistry and movement). ≥70 is read as "resists well", 45–69 as "moderately resists", below 45 as "is vulnerable to".

Climate → agent edges fire when a climate's driver value (UV, humidity, salt or freeze-thaw load) is 60 or above, read directly from the climate dataset.

Treatment → agent / standard edges come from the paraphrased standards corpus used across the site (EN 927-1, EN 351-1, EN 350 clause 4, EN 13501-1).

Species → standard edges reuse the exact source list already published for each Global WoodIntel Score sub-score.
