Cork

Bark harvested without felling the tree — renewable every 9 years.

What it is

Cork is the outer bark of the cork oak (Quercus suber), stripped by hand every ~9 years without harming the tree. Trees live 200+ years and sequester more carbon after harvest.

Why it matters

Cork forests (montados) are biodiversity hotspots that depend on continued harvesting for their economic survival. Buying cork directly funds their preservation.

Upsides

  • Harvest doesn't fell trees; the same tree is harvested for centuries
  • Cork oaks store more carbon after stripping
  • Naturally water-resistant, hypoallergenic, antimicrobial
  • Fully biodegradable

Trade-offs

  • Most cork comes from Portugal — shipping footprint outside EU
  • Cork composite (agglomerated) often glued with synthetic binders
  • Not all 'vegan leather cork' is pure cork — may have PU backing

What to look for on the label

FSC-certified cork, ideally from Portuguese montado forests with disclosed binder type.
