Food Loss GHG Calculator

An emerging markets-focused tool to estimate GHG emissions associated with crop loss

About the Tool

When food is lost between farm and fork, the energy, water, fertilizer, and other resources along the value chain that went into producing this food are also wasted. In addition, food that is discarded often decays generating methane a strong greenhouse gas. With support from GAFSP, IFC, in partnership with Carbon Trust, developed a first-of-its-kind tool to estimate the GHG and cost savings associated with reducing food losses. The tool reported GHG emissions broken down by value chain phase (production, transport, storage, processing, retail, and landfill) for 50 crops/foods in 117 emerging countries. The tool was peer-reviewed by FAO and Cranfield University.

Our Methodology



of the food produced in the world is lost or wasted

One effective way to meet the demand for more food is to reduce the significant food loss and waste
