  A third of greenhouse gas emissions are attributable to the food sector. A
shift in dietary habits could reduce these by half. Engaging and empowering
consumers is vital to this critical shift; yet, if we get the framing wrong, we
might cause distress or eco-anxiety, impeding initial engagement as well as
longer-term diet change. Evoking joy is a powerful yet under-explored motivator
to overcome psychological barriers and support pro-environmental attitudes.
This pictorial presents the outcomes of a one-day workshop as a series of
speculative ideas in the form of an annotated portfolio, highlighting design
qualities and interaction mechanisms that afford joy and sustainability in food
choices. Our contribution will inspire HCI researchers and designers to
reposition joy as a fundamental value to sustainability communication
