ICMM is an international organisation dedicated to a safe, fair and sustainable mining and metals industry. Bringing together 27 mining and metals companies and over 35 regional and commodity associations, we strengthen environmental and social performance. We serve as a catalyst for change, enhancing mining’s contribution to society. Every ICMM company member adheres to our Mining Principles which incorporates comprehensive environmental, social and governance requirements, robust site-level validation of performance expectations and credible assurance of corporate sustainability reports.

“ICMM and its members – representing about a third of the global industry – have an unwavering commitment to safer tailings facility management. ICMM’s Council welcomes the new Global Industry Standard on Tailings Management as a significant step forward in achieving this commitment. Through effective implementation of this Standard, ICMM members will set the bar for all mining companies to work together to make all tailings facilities safer.

“The Standard will be integrated into ICMM’s existing member commitments, which includes third party assurance and validation, and we are in the process of developing supporting guidance. Members have committed that all facilities with ‘Extreme’ or ‘Very high’ potential consequences will be in conformance with the Standard within three years of today, and all other facilities within five years.”

United Nations Environment Programme (UNEP)

The United Nations Environment Programme is the leading global environmental authority that sets the global environmental agenda, promotes the coherent implementation of the environmental dimension of sustainable development within the United Nations system, and serves as an authoritative advocate for the global environment. UNEP’s mission is to provide leadership and encourage partnership in caring for the environment by inspiring, informing, and enabling nations and peoples to improve their quality of life without compromising that of future generations.

“The approach to mine tailings facilities must place safety first by making environmental and human safety a priority in management actions and on-the-ground operations. The Global Industry Standard on Tailings Management is an important milestone towards the ambition of zero harm to people and the environment from tailings facilities. Its impact will depend upon its uptake and UNEP will continue to be engaged in its rollout. We are encouraged by the ICMM role and commitments on Standard implementation and call on the rest of the mining industry, and those that finance and invest in the mining industry, to make a similar commitment. In order to maintain the integrity of the Standard, it is crucial that a non-industry organisation identify and pursue the most effective implementation model such as the establishment of an independent entity. To this end, UNEP will continue to engage in dialogue with other interested stakeholders to explore potential solutions.”

The Principles for Responsible Investment (PRI)

The PRI is the world’s leading proponent of responsible investment. It works to understand the investment implications of ESG factors and to support its international network of investor signatories in incorporating these factors into their investment and ownership decisions. The PRI acts in the long-term interests of its signatories, of the financial markets and economies in which they operate, and ultimately, of the environment and society as a whole.

“Alongside our investor representatives – the Swedish Council of Ethics and the Church of England Pensions Board – the PRI is very pleased with the appointment of Professor Oberle to chair the independent mail tailings review. The Professor’s experience and expertise will be a tremendous asset in this role, and we hope to see robust investor engagement around an international standard for the safe management of tailings storage facilities in the near future.”

Fiona Reynolds, CEO: PRI


“For decades people have called for a global standard that can drive best practice. It is tragic it has taken the Brumadinho disaster to make this happen, but a unique partnership has come together to address a systemic challenge faced by the mining sector and we are now as committed to make this common practice in all operations. For the first time we have a global standard that goes beyond existing best practice and establishes the most comprehensive Standard that Investors will hold companies accountable for in their implementation. I look forward to working with all parties to establish an independent entity which will oversee the implementation of the Standard”

Adam Matthews, Director Ethics & Engagement, Investment Team: Church of England Pensions Board (representing PRI)


“In January 2019 we called for there to be a new industry standard that drives best practice to address the risk of tailings facility failure, and we have been assured by the Global Tailings Review’s independent expert panel that if this standard had been in place, the disaster at Brumadinho would not have happened. We expect all mining companies to comply with this framework, and responsible investors looking to address the risks of tailings failure now have a responsibility to drive implementation, incorporating the Standard into stewardship and active ownership strategies.”
