Opt for suppliers who provide transparency across their supply chain, support take-back or recycling programs for end-of-life breakers, and offer certification documents confirming compliance with ISO 14001 environmental management, green building codes (LEED, BREEAM), or eco-labels. These attributes not only lower environmental risk but can provide a competitive edge in tenders, as sustainability credentials are increasingly weighted alongside price and technical performance.

Furthermore, buyer due diligence should include verification of working conditions and labor practices in the value chain—ensuring that manufacturers abide by ILO conventions and are free of human rights abuses. As ESG (Environmental, Social, Governance) standards tighten worldwide, circuit breaker procurement strategies should integrate supplier audits, demand for published sustainability reports, and preference for products with clear eco-design features such as reduced hazardous content, recyclability, and minimal packaging.
