Reporting Period: 2019

Environmental Metrics

Waste Generated:931 million tonnes/year

ESG Focus Areas

  • Food Waste

Environmental Achievements

  • Reduced global food waste estimates by providing a new estimate of global food waste.

Social Achievements

  • Improved understanding of the scale of food waste and its impacts, highlighting the need for action in low-, middle-, and high-income countries.

Governance Achievements

  • Published a methodology for countries to measure food waste, enabling consistent reporting under SDG 12.3.

Climate Goals & Targets

Long-term Goals:
  • Halve food waste at the retail and consumer level and reduce food loss across supply chains by 2030.
Medium-term Goals:
  • Encourage widespread adoption of a Target-Measure-Act approach to food waste reduction.
Short-term Goals:
  • Support member states in developing food baselines and strategies.

Environmental Challenges

  • Low global food waste data availability and highly variable measurement approaches.
  • Uneven distribution of data between regions and income groups.
  • Key data gaps at the household level in low-income countries, small island states, Central Asia, and Northern Africa, and at the food service and retail levels more broadly.
Mitigation Strategies
  • Developed a three-level methodology for food waste measurement (Levels 1, 2, and 3), increasing in accuracy and resource requirements.
  • Provided a framework for countries to transition to a common global measurement approach.
  • Offered guidance on appropriate measurement methods for different sectors (manufacturing, retail, food service, households).
