Policy Mix for a Low-Carbon Food System

This perspective article examines how policy innovation can accelerate the transition toward a low-carbon food system by combining “hard” policy tools such as carbon pricing and emissions trading systems (ETS) with “soft” behavioral interventions such as nudges and reflective behavioral tools (“nudge+”). The authors argue that current food systems contribute approximately one-third of global greenhouse gas emissions, with animal-based foods generating substantially higher emissions than plant-based foods.
