Climate change presents the largest global challenge in human history. In order to achieve ambitious climate goals, we need a rapid worldwide decarbonization of all sectors enabled by a socio-technical transformation. Previous research argues that the transition is hindered due to researchers’ disciplinary lock-in that only addresses one piece of the complex phenomenon. This article contributes to this discussion by developing an integrated decision-making model for climate change action. The framework builds on climate change literature from multiple disciplines. It identifies key conditions (stages) influencing people’s decisions about climate action. In order to achieve the transition towards a low-carbon society, a variety of climate policies is needed that address different stages of the decision-making model. These consist of a mix of short-term fix policies such as incentives and carbon pricing, and long-term policies fostering social change by addressing our deeper societal values that redefine social well-being and happiness. https://doi.org/10.1016/j.cosust.2021.10.003
