The way we do business is increasingly important to our stakeholders who want assurance that we not only conduct ourselves responsibly and ethically, but also that suppliers and customers across our value chain do so as well. We look for opportunities to improve transparency about our business practices and work to ensure our people understand and fulfil their obligations. We participate in assessment and accreditation programs to verify our performance and identify opportunities for improvement so our stakeholders can have confidence in the way we work.
We expect our people to uphold the highest standard of integrity, act ethically and do the right thing. This expectation extends to our partners, that they behave and operate in a way that aligns with our values and priorities.
Our code of conduct, The Way We Work, sets clear expectations on how we should conduct our business, and ourselves, no matter where we work or where we are from. We want everyone to have the courage to speak up when something is not right, to show integrity and take decisive action where needed. This is not always easy but being courageous means doing it anyway. Our Code applies to everyone who works for Rio Tinto, including our Board, Executive Committee, employees and third parties working under the direction of Rio Tinto.
We know that our reputation to act ethically and with integrity depends on the actions and decisions we make each day across our business. We empower and equip our people to seek guidance when faced with an ethical or business integrity dilemma – both to prevent incidents from occurring, and to protect them and others from harm.
Our ethical decision-making model helps us to pause, reflect and consider our choices and their potential impact when making decisions.
Our Ethics and Compliance program, which is managed by our Ethics and Compliance function independently from our business operations, is designed to identify and actively support in management of our compliance risks and regulatory requirements in the jurisdictions where we operate. We continuously evolve the program to align to the current risk profile of our assets and business activities and to enable timely and targeted intervention to prevent issues from occurring.
Our Business Integrity Standard and Procedure require our employees, core contractors and any third parties acting for, or on behalf of, the company to not commit, authorise or be involved in bribery, corruption, fraud or other economic crimes. We also have clear rules regarding third-party benefits, managing conflicts of interest, facilitation payments, sponsorships, donations and community support, mergers, acquisitions and joint ventures, and engaging third parties.
Supporting the country’s continued growth and development through tackling corruption is a significant priority in Mongolia. As the largest international investor in Mongolia, we are committed to supporting the country’s efforts to promote transparency, business ethics, and corporate governance.
We have partnered with the Mongolian National Chamber of Commerce and Industry (MNCCI) and Transparency International, to establish a dedicated Business Integrity Centre. The Centre offers professional training, resources, and advisory support to approximately 5,000 Mongolian companies to embed global standards in ethical business practice. By working in partnership, the Centre is helping to build the capacity of Mongolia’s businesses and enhance the country’s position as an attractive location for international investment.
The Centre has provided business ethics and compliance training to around 110 private-sector employees from 30 companies across various industries.
Business integrity is core to how we build trust with our stakeholders and the foundation of our ability to run our operations and maintain an ethical culture. Our Ethics and Compliance program is continuously evolving to align with leading industry practice, the regulatory landscape and specific business integrity risks we face across the countries where we operate.
We have continued to develop our Ethics and Compliance program to align with our risk profile and to changes in the regulatory landscape across the countries where we operate. During the year, we undertook a maturity assessment of our program, which concluded our program has a higher level of maturity than benchmarked peers.
In 2025, we:
Our reputation as a business that operates with high levels of integrity depends on the actions we take and decisions we make each day. We expect our people to uphold the highest standard of integrity, act ethically, and do the right thing for each other, for our partners and for the communities where we operate.
We empower our people to seek guidance when faced with ethical or business dilemmas – both to prevent incidents from occurring, and to protect them and others from harm. The way we treat our people, our partners, the environment and the communities where we work, and how we conduct business, is what makes us a responsible partner of choice.
Our employees are required to complete annual mandatory training on The Way We Work, our Code of Conduct. In 2025, we tailored the training to employee needs through adaptive learning. This training sets the foundation for how we work, guiding ethical decision making and reflecting the safe and respectful environment we want to achieve for our people. The annual training incorporates topics across all areas of the Code and is designed to help employees and contractors understand what’s expected of them, providing guidance for making decisions consistent with our values of care, courage and curiosity.
The 2025 annual online training was released in September and has been completed by 21,693 employees. The offline version has been completed by 17,182 employees. Our Executive Committee attended an immersive face-to-face session on the Code.
In addition to annual mandatory Code training, the Ethics and Compliance team delivered additional risk-based face-to-face training on anti-bribery and corruption, data privacy, anti-trust and trade sanctions. A total of 7,519 employees received this training in 2025. We also provided business integrity training to our third parties on a risk basis.
myVoice is our whistleblower and confidential reporting program.
A respectful and inclusive workplace, with a strong ethical culture that reflects our values, must include a safe space where individuals can speak up with confidence and without fear of retaliation.
A strong culture of speaking up enables us to identify and address potential issues swiftly, respond appropriately, minimise risk, and ensure care for our people and the communities where we operate.
myVoice is available to anyone who has concerns or information relating to misconduct or improper circumstances or behaviours connected to Rio Tinto.
These can include concerns about business activities, or behaviours of individuals, including suspicion of violations of our Code of Conduct, policies and standards, human rights, safety, environment, financial reporting, fraud or other business integrity issues.
myVoice lets you choose to submit a report confidentially or anonymously. It is important to know that the content discussed and the right to anonymity may be subject to local laws.
The number of reports received to myVoice1 continues to increase yearly, with 1,9422 reports in 2025 (2024: 1,920). The reporting rate per 100 headcount was 3.4 in 2025 (2024: 3.4), with 51% (2024: 54%) of reporters willing to reveal their identity. The percentage of anonymous reporters has increased each year since 2022. Of the 608 reports investigated and closed in the year, the substantiation rate was 43% (2024: 44% of 642)3.
We remain committed to eliminating harmful behaviours. Behaviours leading to harm are encouraged to be reported to myVoice. In 2025, we substantiated 88 allegations4 of bullying and harassment, 66 allegations of sexual misconduct, and 17 allegations of discrimination.
Disciplinary outcomes from myVoice reports closed in 2025 resulted in 126 employees leaving the business (dismissal or resignation), 85 of these related to harmful behaviours.

This year we continued to embed the Care Hub, which is a confidential service to access support, and explore non-investigative resolution options. Care Hub helps manage psychosocial risks, address systemic hazards and prevent harm. The service is available to anyone directly or indirectly impacted by disrespectful or harmful workplace behaviours, such as bullying, harassment, sexual harm, racism and discrimination. Care Hub supported 702 individuals in 2025 (up from 568 in 2024). 208 non-investigative resolutions were facilitated during the year, an increase from 167 in 2024.
