Sherritt recognizes the critical role businesses play in addressing global climate-related challenges. We implement a robust management system that is underpinned by global best practices and is designed to ensure strict compliance with regulations and our operating licences. We continually seek ways to minimize the impacts of our operations on the environment.

Climate

Sherritt recognizes the critical role businesses play in addressing global climate-related challenges and acknowledges that transitioning to a low-carbon future implies a significant increase in demand for responsibly sources metals such as nickel and cobalt. Sherritt supports the international climate change goals outlined in the United Nations Framework Convention on Climate Change and the Paris Agreement. To reflect this, Sherritt has established a climate change strategy informed by our four guiding principles: Adapt, Mitigate, Innovate and Enable.

Our approach is informed by four guiding principles:

Sherritt continues to collect independent information on the carbon intensity of our operations, complete independent climate risk assessments, assess and refine our absolute emissions reduction targets and plans accordingly, and prepare for alignment with reporting guidelines. As we progress on the development of our decarbonization strategy, Sherritt expects to incorporate a combination of both abatement tools and offsetting opportunities.

For more information on our climate risk and opportunities approach and a summary of our performance in 2024, please see our 2024 Climate Report.

Water

Sherritt recognizes that water is an important shared resource, integral to the well-being of communities, essential for ecosystems and a vital input for our business. Sherritt’s operations are continually taking steps to identify how to optimize practices and minimize the amount of water we use.

Water management at each of our sites is tailored to specific technical requirements, local climate, water bodies and stakeholder interests – all governed by our overarching Water Management Standard. Through implementation of the Water Management Standard, our sites are able to effectively:

Tailings

Sherritt’s goal is that its joint venture operates and maintains its tailings management facilities in accordance with global best practices for safety. We continually review our facilities and procedures and are committed to pursuing the highest standards at our operations.

There are several tailings management facilities (TMFs) at Moa Nickel. A geotechnical engineer is employed to provide oversight of design, construction and operation of the tailings facilities. Third-party engineering firms are utilized in the design and monitoring of tailings facilities, and an Independent Tailings Review Board (ITRB) provides third-party audit and assurance activities and issues binding recommendations.

An annual Tailings Action Plan is established at Moa Nickel, based on inputs from the ITRB, operational staff and third-party engineers to document targets for advancing reclamation on facilities undergoing closure, retrofit historical TMFs to better meet today’s standards and maintain long-term storage capacity aligned with the Moa Nickel life of mine. We continually review our facilities and procedures and are committed to pursuing the highest standards at our operations.

As a member of MAC, Sherritt is committed to implementing and achieving the highest standards contained in the TSM Tailings Management Protocol. Sherritt recognizes MAC’s guidance documents on tailings management as a benchmark of good management practice.
