Food systems, which encompass all stages from production to consumption and waste management, are one of the main drivers of climate change. According to United Nations data, approximately one third of global greenhouse gas emissions come from this system as a whole.

In particular, emissions associated with agriculture and land use stand out, such as methane from livestock farming, the impact of fertiliser use and changes in land use. Added to this is a particularly significant factor: food waste, which accounts for between 8% and 10% of global emissions, highlighting the inefficiency of producing food that is ultimately not consumed.
