Abstract: The transition to sustainability will be difficult. Environmental sustainability entails living within the Earth’s limits, yet the majority of scientific studies indicate a condition of overshoot. For mainstream economists sustainability means perpetuating economic growth. Consequently, environmental and economic sustainability are incompatible in the present institutional context. This paper seeks to develop a new theory of sustainability based upon historical and institutional contexts, the role of economic crises, as well as focusing upon energy quality and meaningful work. Mainstream economics, which emphasizes market self-regulation and economic growth, is not a good vehicle for a theory of sustainability. Better insights are to be found in the literature of heterodox political economy and political ecology. Political ecology is based upon the theory of monopoly capital. Monopoly capitalism exhibits a tendency towards stagnation, because the economic surplus cannot be absorbed adequately in the absence of system-wide waste. The Monthly Review School continues this tradition in the context of the metabolic rift, while the Capitalism, Nature and Socialism School develops the idea of a second contradiction of capitalism. The Social Structure of Accumulation school pursues the idea of long swings of economic activity based upon institutional structures that aid or inhibit capital accumulation.
