The global agrifood system has been largely overlooked in the fight against climate change. Yet, greenhouse gas emissions from the agrifood system are so big that they alone could cause the world to miss the goal of keeping global average temperatures from rising above 1.5 centigrade compared to preindustrial levels. Greenhouse gas emissions from agrifood must be cut to net zero by 2050 to achieve this goal. 'Recipe for a Livable Planet: Achieving Net Zero Emissions in the Agrifood System' offers the first comprehensive global strategic framework to mitigate the agrifood system's contributions to climate change, detailing affordable and readily available measures that can cut nearly a third of the world's planet-heating emissions while ensuring global food security. These actions, which are urgently needed, offer three additional benefits: improving food supply reliability, strengthening the global food system's resilience to climate change, and safeguarding vulnerable populations. This practical guide outlines global actions and specific steps that countries at all income levels can take starting now, focusing on six key areas: investments, incentives, information, innovation, institutions, and inclusion. Calling for collaboration among governments, businesses, citizens, and international organizations, it maps a pathway to making agrifood a significant contributor to addressing climate change and healing the planet.
