Sustainability Score

62%
While Hydrobuilder promotes sustainable growing practices through their products, their corporate sustainability practices show room for improvement. They have basic recycling programs and some energy-efficient warehouses, but lack transparency in supply chain management and comprehensive environmental reporting. Their packaging could be more eco-friendly, and their carbon footprint reduction goals are not clearly defined. Limited public information about labor practices and supplier standards affects their overall rating.
