Abstract
The complex interwoven crises of climate disruption and biodiversity loss demand not only rapid technological innovation for sustainable development but also major shifts in consumption and behaviour, implying a need for responses rooted in ethical values and a reorientation of attitudes towards the more-than-human world. In this context, given the global significance of faith communities and institutions as motivators and moral authorities, it is important that faith leaders state the challenges for sustainable development and suggest pathways forward to protect the environment and people that live in it. Building on his landmark encyclical of 2015, Laudato Si’, Pope Francis issued Laudate Deum, an apostolic exhortation on the climate crisis, and followed this up with a message to COP 28 for leaders to show leadership in facing up to the climate challenge. We argue that the interventions of Pope Francis point to the crucial importance of an approach to sustainable development that can integrate faith perspectives on social and ecological ethics with the knowledge generated by the natural sciences and by environmental systems science. The interdependence revealed by the emerging scientific understanding of human, animal, and ecosystem life implies the bioethics of care and stewardship, which have the potential to bring people together across religious and disciplinary divides. Unlike other analyses, we argue that it is important to understand how life was created if we are to care for it effectively and sustainably. We also put forward the case for more sustainable land use and the production of more sustainable foods. This article is written from the perspective of the Catholic Church, including its approach to moral theology, but we argue that the implications of the analysis are relevant to all faith communities and religious institutions seeking to promote sustainable development.
