This book provides an accessible introduction to environmental politics through a powerful, discourse-centred approach which analyzes how environmental affairs are constructed and interpreted through language. It recounts developments beginning with the arrival of environmental crisis in the late 1960s, which yielded dire warnings about global shortages and ecological collapse. It moves through subsequent decades to the Paris Agreement on climate change, the UN’s Sustainable Development Goals, and the anti-environmental backlash of denial and “Gray Radicalism”. The book develops an innovative approach to understanding contemporary environmental discourses, covering ecological limits and planetary boundaries, pragmatic problem-solving, sustainability, ecological modernization, and green radicalism, as well as radical anti-environmentalism. It analyzes key developments in environmental affairs alongside many examples that illustrate how discourses shape past and current debates on the environment. It concludes by examining the radical implications of the Anthropocene concept.
