Abstract
Tracking and goal setting are popular approaches in the personal health and fitness industry. In this
paper we use a similar approach to assist users in their journey for a more sustainable lifestyle, starting
with food. We employ Action Design Research (ADR) methodology to develop an application and
subsequently propose design principles for developing blockchain-based applications for assisting users
on their path to eating environmentally friendly food. The path to a sustainable lifestyle can be hard as
individuals often do not realize their personal impact towards achieving a net zero carbon future. To
address this shortcoming, this study conducts an ADR experiment to create affordances for users to
learn, create impact and realize that they are not alone in this journey thus motivating users to a
sustainable lifestyle. The design principles that emerged from the project are design for categories and
labels, design for measuring collective impact, and design for rewards and redemption.
