What requirement is associated with Leadership Credit 5 for vendors?

Taking back all products and packaging is a critical requirement associated with Leadership Credit 5 for vendors. This initiative is designed to promote a circular economy, where materials are reused and recycled rather than ending up in landfills. By ensuring that vendors commit to take back their products and packaging, it emphasizes accountability and responsibility in waste management. This not only minimizes environmental impact but also encourages sustainable practices throughout the lifecycle of a product.

On the other hand, the other options do not align with the core focus of Leadership Credit 5. Providing discounts to customers, developing new marketing plans, and increasing online sales focus more on marketing and business strategies rather than addressing responsibility toward waste and sustainability. These aspects, while beneficial for business growth, do not specifically contribute to the environmental goals associated with taking responsibility for product lifecycle management.
