Many high-carbon activities are also highly routinized. From a psychological perspective, this bears the hallmarks of habitual behavior, in that environmentally significant actions are often stable, persistent, and an automatic response to particular contexts (159), e.g., commuting by car repeatedly over many months or years. Theories of social practice offer a contrasting account in which routines coevolve with infrastructures, competencies, conventions, and expectations (160). For example, developments in urban infrastructure, everyday routines, and the shifting social significance of private transport have culminated in the car becoming a dominant mode of mobility (161). Elsewhere, coordinated developments across spheres of production and consumption have led to the freezer becoming regarded as a domestic necessity (162), and changing patterns of domestic labor and shifts toward sedentary recreation have contributed to the rise in indoor temperature control (163). Although such assemblages shift over time, policy and action intended to reduce emissions have been ineffective in coordinating changes throughout these social and material configurations. As a consequence, routinized, commonplace, and largely unconscious behaviors remain mostly unaffected, with many high-carbon activities even growing and expanding (e.g., frequent flying).
