Heineken uses a Product-Service System (PSS) business model that is product-oriented and focused on creating value. The company's sustainability program called "Brewing a Better World" integrates sustainability into its strategy. This includes making the supply chain more sustainable by helping suppliers, especially in Africa, become more efficient and adopt practices like new seed varieties. It also focuses on reducing resources used in brewing like water, CO2 emissions, and electricity through initiatives like its Total Productive Maintenance Program. While Heineken works to build sustainable supplier relationships, it could better communicate and market these efforts to increase visibility and trust with stakeholders.
