Pezzullo has brought attention to the modern issues of environmental justice in a world of consumerism and political economics. She discusses and analyzes these topics in terms of communication and social effects in her book, Toxic Tourism: Rhetorics of Travel, Pollution, and Environmental Justice, and in many of her published articles. Toxic Tourism won the Jane Jacobs Urban Communication Book Award, the James A. Winans-Herbert A. Wichelns Memorial Award for Distinguished Scholarship in Rhetoric/Public Address, the Christine L. Oravec Research Award in Environmental Communication, and the Book of the Year Award for the Critical and Cultural Studies Division. With Robert Cox she coauthored Environmental Communication and the Public Sphere, 4th Edition, a textbook in the environmental communication field. The book discusses the history and development of the field of environmental communication, the modern implications of the field, and the ways humans and the environment interact with and influence each other. It also talks about how human beings react to environmental issues or problems, and how we choose to act in relation to these perceived problems. Environmental Justice and Environmentalism: The Social Justice Challenge to the Environmental Movement, which Pezzullo edited alongside philosophy professor Ronald Sandler, discusses the tensions and angles of two intertwined movements of environmentalism and environmental justice. The former has been criticized by the latter for perceived racism, elitism, and lack of humanitarian concern. The text also analyzes both sides in context of changing climate, environmental laws, and attitudes in the US. Related to Pezzullo's environmental focus is her concern with "pinkwashing", a phenomenon discussed in her article "Resisting 'National Breast Cancer Awareness Month': The Rhetoric of Counterpublics and their Cultural Performances". The idea of pinkwashing centers on businesses' disingenuous participation in National Breast Cancer Awareness Month not out of concern for health, but for purposes of cosmetic targeting, gendered performance, and public relations. Pezzullo says these campaigns fail to address environmental pollution as a large cause of breast cancer, possibly because the corporations in question contribute to this very pollution. Pinkwashing a campaign is a way for businesses to appear moral while earning more money from consumers who believe they are contributing to a just cause, as the campaigns increasingly focus on gendered images of beauty, breasts, and pink imagery.
