Reporting our performance

Our materiality assessment records the

threshold at which an issue or topic becomes

important enough for us to report on

externally. The importance of a topic is based

on the significance of its impacts on, and

risks and opportunities for, stakeholders. Our

ESG materiality assessment considers our

impacts externally and, conversely, the effect

of external factors on our business.

As an ICMM member, we commit to

reporting on our ESG performance against

the Global Reporting Initiative (GRI)

standards and implementing the ICMM

Performance Expectations (PEs). The ICMM

Mining Principles framework focuses on the

implementation of systems and practices

related to a broad range of ESG areas. In

2022, we disclosed that we prioritised 26 of

our 29 operating assets for validation within

the 3-year cycle (2023-2025). There are now

30 operating assets and we have prioritised

one additional asset for validation in 2025,

thereby resulting in a total of 28 out of our 30

operating assets being prioritised for

validation. Since 2022, we have been

progressing the validations according to plan.

In 2024, on-site third-party validations were

completed for 12 of our priority operating and

refining assets. The validation reports

demonstrate a high level of alignment

between the self-assessment and validation

outcomes, with identification of relevant

areas for improvement. Information for the

2023 and 2024 validation results is

presented in the ICMM PE Summary tab in

the 2024 Sustainability Fact Book. In 2024,

we have also introduced a new tab showing

the Towards Sustainable Mining (TSM)

outcomes for 3 of our Canadian sites and all

of our Pilbara iron ore sites. We have

continued to improve our reporting to meet

additional disclosure requirements, including

the ICMM Social and Economic Reporting

Framework (SERF). In 2024, we have

disclosed our performance against the SERF

indicators in the ICMM SERF tab.

The majority of our ESG reporting is

incorporated into this Form 20-F and

supplemented by our 2024 Sustainability

Fact Book, containing current and historical

data on topics including health, safety,

environment, climate, communities, human

rights, responsible sourcing, ICMM PEs

and transparency.

Governance and assurance

The Sustainability Committee oversees

strategies to manage social and

environmental impacts, risks and

opportunities, including management

processes and standards. The Sustainability

Committee reviews the effectiveness of

management policies and procedures

relating to safety, health, employment

practices (apart from remuneration, which is

the responsibility of the People &

Remuneration Committee), relationships with

neighbouring communities, environment,

tailings, security and human rights, land

access, political involvement and sustainable

development. Given its strategic significance,

climate change is overseen directly by the

Board.

For more information about our Sustainability Committee see pages 117-118.

This year, the Group’s auditor, KPMG, was

engaged to provide the Directors of Rio Tinto

with assurance on selected sustainability

subject matters. KPMG’s limited assurance

statement satisfies the requirements of

subject matters 1 to 4 of the ICMM

assurance procedure.
