Background: This paper aims to extend the application of social marketing to social and environmentally beneficial behavior change providing a three-step process—Co-create-Build-Engage (CBE). The key strength social marketing brings to the social change space is the development of something of value that moves and motivates people to voluntarily change their behavior; in turn benefitting themselves, the planet and society at large. Method: Using a case study method, this paper identifies how up to eight marketing principles, initially penned to distinguish social marketing from public health, are applied in the three step CBE process, using first time program development and implementation examples. First, programs are co-created (C) with people at the heart of the problem and built (B) to create and embed lasting solutions and finally communities are engaged (E) to partake in these programs. This linear process is applied in first time program development and stages blur following first time implementation as CBE steps become continuous when programs are embedded into communities. This paper outlines four cases demonstrating when and where key marketing activities were applied to co-create, build and implement social marketing programs that achieved behavioral change. Results: Included is a roadmap of the activities that occurred in first time program development and implementation across each stage of the three step CBE process. During co-creation competition is assessed and groups are identified (segmentation). Formative research programs are theoretically underpinned and human centred (customer orientation) and solely aimed at identifying insights to guide program build and engagement. Elements of the marketing mix focus program build ensuring that a valued exchange offering is built. Engagement represents the initial implementation phase and encompasses the set of activities that focus on ensuring people are aware of and can adopt the program. Recommendations for Research or Practice: Many of the foundational techniques that distinguish social marketing from other behavioral science approaches are not widely adopted. This paper offers a roadmap to demonstrate how and when core social marketing activities can be applied to effect voluntary behavior change. Volitional change avoids stigmatization, alienation, reactance and community divides, which occur when behaviors are mandated or when people are told what to do. The CBE process provides a process, outlining social marketing’s key principles and the set of activities that are applied to build more effective marketing programs.
