This chapter presents the needs, current state and options for accelerating a food system transformation. It focuses on GHG emissions and climate change, but also discusses important synergies and trade-offs with the environmental, health, and economic/equity dimensions throughout the chapter. The chapter will present and discuss transformative solutions that can decrease emissions in the supply and demand side of food systems along with examples of initiatives already in place in various parts of the world. It will also discuss how further actions can be accelerated to ensure that food systems contribute their share to fulfilling the goals of the Paris Agreement.
