Sustainability Score
72%
While Kosterina demonstrates commitment to sustainable farming practices and uses organic methods in their olive groves, there's room for improvement in transparency regarding their complete supply chain and packaging sustainability. They maintain fair labor practices and support small-scale farmers, but their carbon footprint from international shipping and limited information about their complete environmental impact affects their score. Their recent initiatives in eco-friendly packaging show promise, though comprehensive sustainability reporting would strengthen their position.
