Whether we work for a startup, agency, or large organisation, we constantly make decisions about what and how we design and who we involve. Driven by short-term goals, it is easy to miss how our decisions cause ripples that can negatively affect ecosystems and future generations. Drawing on global trends, academic research, and decades of experience as designers and educators, Martin Tomitsch and Steve Baty demonstrate how we can leverage strategic design tactics to drive positive change. Packed with case studies, tools, and strategies, the book offers a practical guide for designers, decision-makers, leaders, and anyone looking for ways to shift their planetary impact.
