Barriers and enablers around radical sharing.

Multiple social and ecological crises are currently unfolding, the tackling of which requires a thorough understanding of their interlinkages and root causes. More sharing of essential resources while increasing access to valuable goods and services, especially for the most vulnerable in society, has been proposed as an effective strategy to reduce environmental and social damage. However, a more reflective approach to sharing is needed to make sure that it does not worsen some of the issues that it aims to address. In this Personal View, we outline the principles of radical sharing, which highlight the salience of environmental limits, access to essential goods and services, and non-exploitative relationships. Furthermore, we discuss key enablers and barriers to radical sharing and a more successful integration into sharing practices that prioritise needs satisfaction for all within planetary boundaries. Critical perspectives on the sharing economy need to account for the role of power, politics, capitalism, and citizenship alongside the more widely discussed issues around exploitation, discrimination, and greenwashing.
