The food system accounts for roughly one-third of global emissions.1 The transition to a sustainable food system represents an incredible opportunity to drive progress against climate change. Emissions attributed to the food system are projected to increase between 60-90% between 2010 and 2050 unless transformative measures are taken.2 Despite this, a sustainable food system transformation remains chronically underfunded, making up only approximately 4% of climate finance.3 This primer on the opportunity aims to help investors and the financial sector reorient climate finance towards food and agriculture to combat climate change, generate positive social impacts and economic returns.
