Today, Food Systems greenhouse gas emissions contribute to roughly a third of global emissions. For a successful transition to happen, the global food systems would, in the next decade (2020s), need to implement cost-effective mitigation practices and technologies, supported by improvements in countries’ governance and technical assistance, innovative financial mechanisms and research focused on making affordable technologies in the following two decades (2030–2050).
Although the impressive commitment to the net-zero agenda of countries and the world’s biggest food companies, guidance offering multiple options for achieving net-zero emissions in global food systems and informing the effectiveness of pledges and catalyze meaningful climate action is still needed. To date, most studies have focused on estimating global food systems emissions and evaluating potential mitigation through a few and aggregated pathways using complex models and none has proposed a roadmap towards net-zero food systems, which has lately been highly demanded by several food systems actors. This work provides options and a vision to guide global food systems to achieving net-zero by 2050.
