Only ten G20 countries, representing the world's largest economies, have comprehensive national legislation specifically designed to prevent food waste, according to Economist Impact. A significant number of these nations are without binding legal frameworks to tackle a pervasive global problem impacting both environmental health and food security. Without such mandates, substantial food loss continues unchecked across major economies.
Around three-quarters of G20 members seek to address food loss in a national strategy, yet only half of the top-performing countries in sustainability have comprehensive food waste legislation. This creates a fundamental tension between high-level commitments and actionable policy. Bridging this gap between strategic intent and enforceable action is crucial for sustainable sourcing in the food industry by 2026.
Without stronger legislative mandates and integrated policy frameworks, the global food industry will likely continue to struggle with widespread food loss and unsustainable agricultural practices, despite voluntary targets.
Defining Sustainable Food Systems: Where We Stand
Sweden, Japan, Canada, Finland, and Austria possess the most sustainable food systems globally, based on the 2021 Food Sustainability Index, according to Economist Impact. This index identifies leaders across various metrics, including food loss and waste. Food loss among these top 20 performing countries stands at just 3% of total food production, significantly below the FSI average of 6%. The low percentage (3%) of food loss in leading nations highlights the potential for substantial waste reduction when effective systems are in place.
While these nations demonstrate strong performance in reducing food loss, household food waste also remains below the FSI average of 85kg per head per year in all but two of the top 20 countries. The Food Sustainability Index (FSI) measures how countries address environmental, societal, and economic challenges in their food systems. Even with these leaders, the global average still indicates substantial room for improvement across food systems, suggesting that even top performers face ongoing challenges in consumer-level waste.
