Unilever has implemented a sustainability plan called the Unilever Sustainable Living Plan. The document discusses Unilever's plan and analyzes its competitive environment using Porter's Five Forces model. It finds that entry barriers are high for the sustainability market and supplier bargaining power is low. However, rivalry is intense and buyer bargaining power is strong. The plan aims to improve sustainability across Unilever's operations, source materials sustainably, and enhance the livelihoods of millions. The document also compares Unilever's sustainability commitments to competitors like P&G.
