The carbon math that matters
Every structural panel has a carbon story. For wood OSB the story is approximately neutral — softwood absorbs CO₂ while growing, releases it when kiln-dried, then re-absorbs a portion over the panel's lifetime. For BAMOSB the story is different: bamboo absorbs carbon roughly five times faster than softwood, the manufacturing chain is shorter, and the panels themselves are denser than typical wood OSB. The result: BAMOSB panels store more carbon per cubic meter than they emit during production. Verified cradle-to-gate, they are carbon-negative.
Verified carbon footprint (ISO 14025, EPD)
BAMOSB's third-party verified EPD reports:
- −1.41 kg CO₂e per kg of panel (cradle-to-gate, including raw bamboo cultivation, strand production, resin, pressing, packaging)
- −680 kg CO₂e per cubic meter of finished 18 mm panel
- Carbon stored in the panel itself: 425 kg CO₂e per cubic meter
How this compares to wood OSB
Typical wood OSB EPDs report cradle-to-gate emissions of +0.45 to +0.85 kg CO₂e per kg of panel (positive number = emissions). A 18 mm wood OSB panel of 11 kg/m² emits roughly 5–9 kg CO₂e per m² in production. A BAMOSB panel of the same thickness removes about 16 kg CO₂e per m².
Net contribution to a building
For a typical 200 m² residential build using BAMOSB as wall sheathing, the embodied carbon balance is approximately −3.2 tonnes CO₂e. This single material switch can offset the equivalent of one passenger flight per household per year.
What "carbon-negative" means for certification
Verified carbon-negative panels qualify for:
- EU Taxonomy alignment for sustainable construction (climate change mitigation criteria)
- BREEAM and LEED credits under Materials & Resources and Low-Carbon categories
- Net-zero building certification under Passive House, DGNB, and WELL frameworks
