This document consists of a summary of best practice standards for coal mine closure and aftercare, complemented by a practitioner's guide. In combination, these two modules can be used by coal enterprises, line ministries, technical agencies, as well as development partners, looking towards mine closures some 5-10 years ahead, to inform plans for closure, repurposing, and transition that have yet to be drafted. The document aims to serve as a benchmark and reference for the World Bank's coal transition engagements, providing global good practice guidance for coal enterprises and line ministries, as well as development partners. At the same time, the two modules serve as a risk-management tool in a type of engagement that is by its very nature characterized by a high environmental and social risk baseline. The two modules are designed to support the planning and implementation of mine closures, repurposing, and transitions in a forward-looking manner over the next 5-10 years. Additionally, the document functions as a risk-management tool, ensuring thorough understanding and management of environmental and social risks associated with coal mine closure and post-closure aftercare. These standards and guidance will be integrated into the World Bank's systematic coal transition approach, available to staff and clients. In conjunction with the Environmental and Social Framework (ESF), this work underscores the World Bank's commitment to proportionate due diligence and global knowledge sharing in coal mine closure practices.
