[Comment] Commercial determinants of active travel: a crucial but overlooked barrier to health and sustainability

Active travel (walking, cycling, and other non-motorised transport) is an important component of active lifestyles and plays a crucial role in improving physical and mental health, reducing greenhouse gas emissions and air pollution, and offering social and economic benefits.1 However, despite its well-documented benefits, active travel remains considerably underutilised in many countries.
