The authors evaluate the potential of green marketing and its limitations in solving society’s environmental problems. The streams of research in the green marketing area are reviewed and their assumptions and efficacies are discussed. While green marketing has some positive societal outcomes, on its own it is an insufficient solution to societal environmental problems in general and to humanity’s existential threat from climate change in particular. The authors analyze and discuss the roles and responsibilities of business, citizen-consumers, and government in contributing environmental solutions.
