In this chapter, we introduce how gender and affect can be co-thought in studies of mobilities and transport, and in particular masculinity and transport practices as this is our main field of expertise. From our perspective, affect in this context implies how people feel and act as a consequence of aroused emotion experienced within an affective economy such as the mobility and transport system (Ahmed 2004; Sheller 2004; Balkmar and Mellström 2020). The affective economy of transport and mobility regulates and channels how travel and mobility patterns organize and include individual, group and societal structures with human and non-human elements. We argue that it is analytically vital to separate affect and emotions with regard to the mobility and transport system in order to outline the systemic dimensions of many ecological and societal challenges of our present time. In the larger land- scape of contemporary challenges, the transport and mobility system is key to halt planetary warming, the endemic traffic congestion of major metropolises and decrease carbon dioxide emissions on a global scale, to mention a few. Our present transport and mobility systems are pressing the planet to a core boundary (Steffen et al. 2011) where the passing of such a limit would drive the planet into a less sustainable level of human life.
