For ABC regional partners
ABCDEX is yours to fill
In its first months ABCDEX grows mainly from its partner regions — and you don’t fill in forms, you send us sources. Drop your region’s best reports, studies and project pages; we extract the crops, products, projects and policies and connect them. A curator confirms the figures before they publish.
Policy benefits
What a stakeholder concretely gets under your region's instruments — value, eligibility, how to claim.
Biobased materials
Construction-grade materials with lambda, density, fire class and EPD-backed carbon figures.
Buildings
Real projects where the farm-to-construction chain ends — with stored-carbon figures.
And it learns from you as you use it
Hover over any part of this site and a small feedback balloon appears in its corner — or use the button at the bottom-right of every page. Tap it to jot a note or leave a voice memo: something that’s wrong, a source we’re missing, an idea. Every note feeds straight into our working board, so ABCDEX becomes a self-learning system — corrected and sharpened in fast iterations rather than waiting on a yearly review. While the project ramps up, this is open to everyone.
Ask the data
Ask ABCDEX a question
Natural-language questions, answered with AI — grounded in the project’s certified crops, materials, regions and policies. Every answer shows its sources.
Ask about crops, biobased materials, landscapes, partner regions and policies — coverage is partner-contributed and grows as regions add their data.
A few numbers
European biobased construction carbon-storage potential
CO₂ stored per year in new buildings — scenario trajectory
Estimated current share: Metabolic / Built by Nature, Impact Scan for Timber Construction in Europe (2023). Storage trajectory (~80%-wood scenario): Amiri et al., Environmental Research Letters(2020) — an ambitious-adoption scenario for 2040, not current performance.
