Our Sustainability Approach

The ASI aims to create sustainability and transparency throughout the aluminium industry. It has developed the world’s first global Responsible Aluminium Standard, used to assess environmental, social and governance practices across the aluminium supply chain for responsible sourcing. We were the first company in the world to receive certification under the Aluminium Stewardship Initiative (ASI).

The BGA aims to solve environmental challenges in ways that create and maintain quality jobs and build a stronger, fairer economy. We are on the Advisory Board of the BGA.

BSR is a global non-profit organisation that works with its network of more than 250 member companies and other partners to build a just and sustainable world. As a member, we share information on sustainable practices.

We are a founding member of the EITI and have played an active role in this global standard since 2003. The EITI promotes open and accountable management of natural resources to make sure our activities benefit the many, not the few. We are transparent about the taxes and royalties we pay – publishing an annual Taxes paid report since 2010.

GRI is an international independent organisation with an international framework and standards for sustainability reporting. Our Group-level sustainability reporting is informed by the GRI Sustainability Reporting Standards (Core option) and the GRI Mining and Metals Sector Supplement.

We participate in the Kimberley Process (KP) through our involvement with the World Diamond Council (WDC). The KP is a joint initiative between governments, diamond industry bodies and civil society organisations, mandated by the United Nations and the World Trade Organization, to stem the flow of “conflict diamonds”.

The LBMA has renewed Rio Tinto Kennecott’s responsible gold and silver certificate, which guarantees that the precious metals produced from Kennecott’s refinery are accepted and traded globally. The certificate is one of the requirements for precious metals refineries to be placed on the LBMA’s Good Delivery List, an internationally recognised standard for quality and responsible production. Many precious metal exchanges will accept gold and silver bars only from refiners who appear on the GDL.

We are a founding member of the Natural Diamond Council whose mission is to advance the integrity of the diamond and jewellery industry to inspire, educate and protect the consumer.

The OECD Guidelines for Multinational Enterprises are recommendations by governments to multinational enterprises operating in or from adhering countries. They include non-binding principles and standards for responsible business conduct in a global context consistent with applicable laws and internationally recognised standards. These guidelines are a multilaterally agreed and comprehensive code of responsible business conduct that governments have committed to promoting.

The Proteus Partnership was formed in 2003 as a collaborative effort between leading extractive companies and the United Nations Environmental Programme World Conservation Monitoring Centre (UNEP-WCMC) to improve accessibility to biodiversity data for better decision making and support the further development of global biodiversity resources. As a Proteus Partner, we have access to the UNEP-WCMC online biodiversity assessment tool, which allows us to scan for potential sensitive areas in places where we are seeking tenure before major investments are made.

The RJC is an international non-profit organisation that promotes transparent and responsible ethical, human rights, social and environmental practices throughout the jewellery industry – from mine to retail. We are a founding member and were the first mining company to be certified in 2012. Since then, we have continued to uphold the ESG standards and maintained RJC certification, which needs to be renewed once every three years. We were re-certified in 2021 against the RJC Code of Practice Standards. RJC certification covers operations or activities of our businesses that produce diamonds, gold or gold in concentrates that contribute to the jewellery supply chain. This includes our diamond mines – Diavik in Canada and Argyle in Western Australia – and our Kennecott copper mine in the US, for gold.

We are a signatory to The B Team Responsible Tax Principles, developed by a group of cross-sector, cross-regional companies to define what leadership in responsible tax looks like. The disclosures in our Taxes Paid Report, available on our website, demonstrate our approach to the B Team’s seven Responsible Tax Principles.

We participate in the TSM programme through our membership of the Mining Association of Canada (MAC). TSM is a sustainability certification scheme that applies to members of MAC operating in Canada.

The UNGPs are a global reference point for preventing and addressing the risk of adverse impacts on human rights linked to business. We seek to operate in a manner consistent with the UNGPs.

The SDGs are a set of 17 goals and 169 targets endorsed by the UN in 2015. These present a broad sustainability agenda focused on the need to end poverty, fight inequality and injustice and respond to climate change by 2030. In 2016, our chief executive signed a public statement of support for the SDGs.

The UDHR is a milestone document in the history of human rights which sets out, for the first time, fundamental human rights to be respected. We respect and support all internationally recognised human rights consistent with the UDHR.

The VPSHR guide extractives companies on how to maintain the safety and security of their operations in line with respect for human rights. Participants, including governments, companies and non-government organisations, agree to proactively implement or support the implementation of the VPSHR. We published our VPSHR report for the first time in 2018 (previously only provided to other participants) and have committed to doing this each year.
