Do you make a conscious effort to reduce the amount of food wasted in your home?

The UN marked the seventh International Day of Awareness of Food Loss and Waste to address the 13 percent of food lost post-harvest and the 19 percent wasted at the retail or household level. These losses contribute significantly to global environmental strain while 645 million people faced hunger in 2025.

Why it matters

Reducing food waste is a primary strategy for addressing both food insecurity and climate change, as current inefficiencies account for up to 10 percent of global greenhouse gas emissions. Managing household waste diversion can help lower these emissions while maximizing the availability of existing food supplies.

Official reporting from the FAO and UNEP identifies that 13 percent of food is lost before retail, while 19 percent is discarded in homes and shops. These figures demonstrate a persistent global inefficiency that remains an active focus of international policy and measurement frameworks.

The players

FAO

The Food and Agriculture Organization leads international efforts to defeat hunger and improve nutrition through sustainable food systems.

UNEP

The United Nations Environment Programme is the leading authority on the global environment, setting the agenda for sustainable development.

The details

Food waste acts as a major driver of methane emissions when organic matter decomposes in landfills without oxygen. To combat this, the FAO and UNEP have introduced new measurement tools and the Youth for Food, Not Waste facilitation guide. These resources provide structured frameworks for local campaigns to optimize food processing and implement organic waste diversion strategies that effectively capture nutrients rather than venting greenhouse gases.

In 2025, 645 million people experienced hunger.
September 29, 2026, marked the seventh International Day of Awareness of Food Loss and Waste.

Health Landscape

This initiative aligns with global efforts to optimize food systems and stabilize climate patterns. It follows the precedent established by the UNEP Limiting Overshoot report in prioritizing systemic reduction of environmental footprints.

Reducing household food waste is a practical way to manage your personal carbon footprint and support local resource efficiency. Consider reviewing your grocery planning habits to minimize spoilage, which can also help you save on food costs.

The takeaway

The significant volume of food lost between harvest and the table remains a critical intersection of human health and environmental stability. Individuals can contribute to solutions by adopting better storage practices and participating in local organic waste diversion programs to reduce methane emissions.
