GTMI – Global Tailings Management Institute

Making Mine Tailings
Facilities Safer

For People &
The Environment

INTRODUCING THE GLOBAL TAILINGS MANAGEMENT INSTITUTE

On 25 January 2019, a tailings dam disaster in Brazil’s Brumadinho claimed 272 lives.

This, and other tailings facility failures, led to decisive action by ICMM, the United Nations Environment Programme (UNEP) and the UN-backed Principles for Responsible Investment (PRI) to make mine tailings facilities safer.

Together, they co-convened the Global Tailings Review, and in 2020 developed and published the Global Industry Standard on Tailings Management (GISTM).

The Goal

To achieve zero harm to people and the environment, with zero tolerance for human fatality.

“The Global Tailings Management Institute has been established to enhance the safety of mine tailings facilities, by promoting widespread adoption and implementation of the GISTM”

WHAT IS THE GTMI?

An Independent Institute To Drive Responsible Mine Tailings Management

The Global Tailings Management Institute oversees the implementation of and conformance with the Global Industry Standard on Tailings Management (GISTM).

With ICMM, UNEP and PRI as founding partners, the GTMI is an independent institution that operates on a non-profit basis.

Companies seeking to meet the GISTM are required to prioritise safety, and enhance accountability through public disclosures at all tailings facilities.

The GTMI is responsible for overseeing the independent auditing, verification and certification against the GISTM.

“Our vision is for all tailings facilities to be responsibly managed across all phases of their lifecycle, with the aim of achieving zero harm to people and the environment.”

THE GTMI BOARD

The GTMI Is Governed By A Multi-Stakeholder Board

It is composed of representatives from industries and communities who have experience with or are potentially affected by tailings facilities.

DEPUTY CHAIR

Vicente Mello

Senior Vice President, AECOM
Brazil

Vicente Mello is a technical and environmental expert and executive with over 30 years of experience leading complex projects in Brazil, Latin America, and Africa. He has worked across the mining, infrastructure, and consulting sectors, holding senior roles including CEO, Director of Strategy, Director of Operations, and Senior Consultant. His expertise lies in environmental risk management, strategic planning, and the implementation of high-complexity projects.

Vicente led Brazil’s Independent Mining Audit Program—reporting to state and federal authorities on the response to the Fundão and Brumadinho tailings facility disasters—making it the largest formal mining audit programme globally. He led the Independent Technical and Environmental team to audit the Rio Doce Agreement between Vale, BHP, Samarco, and Brazilian authorities, the world’s largest environmental and social restoration agreement signed after the failure of a tailings dam. He has advised federal judges on topics ranging from ecological risk and water safety to housing, food contamination, and biodiversity recovery.

He has also led the team which supported Brazil’s National Mining Agency in inspecting 229 high-risk dams and contributed to policy development for upstream tailings dam closure. Vicente serves on multiple expert panels, including for the UN Environment Programme.
