The New Prometheans: Technological Optimism in Climate Change Mitigation Modelling

Technological change modelling (TCM) is quietly transforming the landscape of environmental debate. It provides a powerful new basis for technological optimism, which has long been a key battleground. The technique is at the heart of mainstream climate change mitigation policies and greatly strengthens environmentalism over ecologism. It seems to show that technological change can solve the problem. I argue that the models employ a flawed understanding of technological change and that policies based on them are a major gamble. The article aims to begin a wider debate on TCM, offering a defence of ecolo-gism rooted in the history of technology and SCOT literatures.
