Aside from Cork Oak’s economic benefit for the local communities, it is also a species of trees that is particularly known to be very good at capturing and storing CO₂ from the air. Lifecycle studies have shown the Cork value chain to be carbon negative (net removal of CO₂ from the air for storage in the tree and soil). Unlike other trees, Cork’s uniqueness ensures the longevity of the CO₂ that is captured and stored by the tree.

Cork Oak’s uniqueness allows Quercus Suber Heritage to produce high-quality carbon credits. It undergoes strict certification and verification procedures by the most reputable global standard, Gold Standard^®.
