As one aspect of religious tourism, pilgrimage tourism can be considered as a powerful force to mitigate climate change and to promote sustainability in general. However, the existing literature on the relationship between pilgrimage tourism has tended to and sustainability focuses on either demand or supply-side perspectives apart from one another. Thus, there is a dearth of understanding about the interaction between religious organizations and pilgrims and how this type of tourism can be harnessed to tackle climate change and ensure sustainability. Drawing from a dynamic capabilities approach, this study aims to: 1) explore how pilgrimage tourism assists to curb climate change, and 2) assess factors that strengthen the dynamic capability of the pilgrimage tourism in combating climate change in the context of Ethiopian Orthodox Church. Draws from in-depth and semi-structured interviews with religious figures and pilgrims, the results of this study indicate that awareness of sustainability by itself is not enough, rather the combination of teaching and practice matter efforts to curb climate change but also to reinforce sustainability. The study highlights the potential of pilgrimage tourism to ensure SDG (Sustainable Development Goals) in the less-developed world context.
