Sustainability Score

62%

While Growers House promotes sustainable growing practices through their products, their own corporate sustainability practices lack transparency. They have made some efforts in sustainable packaging and energy-efficient shipping practices, but there's limited information about their supply chain ethics and environmental impact. The company could improve by implementing clear sustainability reporting and establishing concrete environmental goals.
