Environmental governance occurs through and is shaped by communication. We propose a typology of public communication, classifying it by directionality (one-way or two-way) and objective (informational or operational). We then review how communication types influence individuals’ conceptual frames, values, and environmental behaviors. Though one-way communication is common, its impact is often limited to influencing conceptual frames. Research on two-way informational communication demonstrates a greater ability to align conceptual frames and values among individuals, and research on two-way operational communication demonstrates the greatest impact on conceptual frames, values, and environmental behaviors. Factors that affect the impact of communication include the medium through which it occurs, trust, timing, and social-material context. Among these, our review considers new directions in public communication research that focus on the role of digital platforms, misinformation, and disinformation. We conclude by synthesizing research on deliberative communication, a case of communication among citizens guided by democratic ideals.
