Although it is often stated that the transportation system is a socially, economically important sector that is particularly vulnerable to climate change, there is still little research on its adaptation. Thus, the object of study of this paper is the vulnerability and adaptability of the urban transport system to climate change. The objective is to identify the level of current and potential contribution of Urban Mobility Plans to reduce the vulnerability of the transport system to climate change. The study starts by analyzing the mobility plans of the cities of Belém, São Luís and Manaus. For this, the methodology follows the guidelines of a qualitative research, anchored in the bibliographical survey, as well as in the analysis of documents and journalistic news, analyzed using the content analysis technique. In summary, it can be highlighted that in the cities analyzed, climate change is not yet perceived as a problem of local relevance. Even though actions for mitigation are present in the guidelines of mobility plans, these are not specific to climate change, being only a standard measure for reducing pollution in cities. And when it comes to adapting the transportation system to reduce socio-climatic vulnerability, public policies hardly direct specific actions.
