Cork oak forests play a vital role in the circular carbon economy by combining environmental, economic, and social benefits. These trees, predominantly found in Mediterranean regions, absorb 3 to 5 times more CO₂ when harvested, as the process of bark regeneration increases carbon uptake. Spanning over 2.2 million hectares worldwide, cork oak forests act as crucial carbon sinks and biodiversity hotspots, supporting endangered species and promoting ecological balance. With a lifespan of up to 200 years, cork oaks provide long-term environmental benefits, including soil stabilization, water conservation, and improved air quality. Their sustainable harvesting process ensures the tree remains unharmed, aligning perfectly with renewable and waste-free principles. As a renewable and biodegradable resource, cork embodies sustainability while fostering rural economies and combating climate change.
