Earlier this year, TDi Sustainability was asked by Mining 2030 to work on a new definition of mining legacy, to support companies and investors in achieving positive legacies in mining operations. This work is part of Mining 2030’s vision to enable a socially and environmentally responsible mining sector by 2030.  

Report now available

This TDi report for Mining 2030 provides a definition of positive mining legacy based on both literature and practice and some guiding principles for positive legacies alongside real-life case studies.
Mining 2030 report

To arrive at a definition for positive mining legacy, the TDi team reviewed both literature and practice. The concept of  is variously referred to as ‘closure’, ‘post-closure,’ and, more recently, “legacy”, reflecting changing understandings across the mining sector. The varied definitions that exist  further reflect the complexity of the term “mining legacy,” shaped by differing legal responsibilities, sites’ status, and impact scopes. While institutional frameworks tend to prioritise environmental remediation and regulatory compliance, academic and civil society perspectives place greater emphasis on social dimensions, community well-being, and the need for inclusive and long-term remedial approaches. As environmental, regulatory and socioeconomic conditions evolve, so too does the nature and significance of mining legacies – making their recognition and management essential to just, future oriented transitions.

The definition developed by TDi considers multiple dimensions of mining legacy, including:

  • Temporal aspects that extend beyond mine closure to consider enduring impacts;
  • Spatial considerations that look beyond the mine site to communities, landscapes, and supply chains;
  • Risk perspectives encompassing environmental, economic, social, human rights, and cultural aspects;
  • Responsibility and governance frameworks for legacy management and transition.

The draft definition produced by the team underwent consultation in 2025 and the final report has now been published.

The TDi team would like to thank the Mining 2030 Working Group for their discussion and input into the report. The development of the report was overseen by the Secretariat for Mining 2030 (Chronos Sustainability Ltd.) and the Mining 2030 Working Group on Legacy chaired by Jill Cooper (Orion Resource Partners) and Zak Wood (Thoreau consulting). We would also like to thank the stakeholders who participated in the public consultation.
