Five decades after the United Nation's first conference on the environment in 1972, the IPCC warned that ‘any further delay in concerted anticipatory global action on adaptation and mitigation will miss a brief and rapidly closing window of opportunity to secure a liveable and sustainable future for all’. Faced with steeply rising greenhouse gas emissions, accelerating biodiversity loss and continued degradation of oceans, forests and soil, the situation appears increasingly baffling. Why do we not see effective measures to turn these developments around? As the situation grows dire, it becomes more mysterious: what exactly is this crisis and why has it proven so difficult to solve? If the problem persists, is it because it is not properly understood? Yet, the environmental question has been studied for decades and diagnoses are legion: capitalism, colonialism, overpopulation, economic growth, humanity's inherent short-sightedness, patriarchy, the private property system – or the tragedy of the commons, the disconnect from nature in Western culture, corporate anti-environmental campaigns, the Neolithic adoption of agriculture – or its more recent industrialisation, the miscommunication of environmentalists and scientists, Christianity and neoliberalism have all been proposed as fundamental causes of the crisis. Despite this long and rich history of debate, it may be, as Pierre Charbonnier argues, that we need a more precise understanding of the ‘ecological question’ to find a way out of the present impasse. In line with Katrina Forrester and Sophie Smith's argument, we are convinced that such rethinking of the environmental must be historical, but also that it must pay special attention to economic aspects. Since the end of the Second World War, economics has risen to prominence as a form of expertise in governance at the expense of other kinds of knowledge, and the environment has become closely intertwined with the economic in the ways it has been governed. In that light, it is not surprising that current discussions among scholars, climate scientists, politicians and social movements hold that the environmental crisis calls for a reevaluation of the economic. History is central to this endeavour and can be ‘usable’ in the current crisis, as it, in Deborah Coen's words, can ‘reveal the contingent and often contradictory traces of the past in the present – and to provide clarity for the future’. In this introduction we discuss three partially overlapping ways in which historical perspectives can be helpful to the effort of constructing an ecologically stable society. In contrast to the general tendency in the twenty-first century academy to divide into ever more specialised fields, we call for a broader conversation among historians of the economic and of the environmental to reveal the paths that brought us here – and the ones not taken. We need new histories of thought, institutions, movements and governance that combine the economic and the environmental to reach a better understanding of the present crisis, decode the specific mechanisms of inaction in the face of looming catastrophe, and strive towards more apt formulations of the environmental. We wish to contribute to an emerging conversation located at the intersection of history of economic thought, intellectual history and political history more generally by pointing to strands of research that could be drawn together and that this special issue is meant to engage in dialogue.
