Sustainability Score
62%
While HTG Supply promotes sustainable growing practices through their products, their corporate sustainability practices show room for improvement. They lack transparent reporting on their environmental impact and supply chain practices. Some positive initiatives include LED lighting programs and packaging reduction efforts, but their overall environmental commitments and social responsibility programs remain limited. Their energy efficiency measures in retail locations are commendable, though documentation of labor practices and supplier standards needs enhancement.
