Introducing Environmental Communication offers a critical and interdisciplinary introduction to the field, designed primarily for undergraduate students in both specialist and general courses, as well as for postgraduate and professional learners. Its modular structure allows chapters to be used independently across a wide range of teaching, training, and coaching contexts. The book addresses underrepresented themes, including intercultural communication, postcolonial studies and social psychology, while combining theory with real-world application through staggered tasks, discussion prompts, case studies, and projects. Each chapter is supported by up-to-date examples and structured to guide learners from foundational concepts to more complex analysis. Adopting a critical lens, power and justice inequalities are highlighted and perspectives from the Global South are amplified, conveying both the urgency and complexity of the field. Short videos with accompanying discussion points are available online, enhancing the book's multimedia resources.
