Governmental regulations

Rio Tinto is subject to extensive governmental regulations affecting all aspects of its operations and consistently seeks to apply best practice in all of its activities. Due to Rio Tinto’s product and geographical spread, there is unlikely to be any single governmental regulation in effect that could have a material effect on the Group’s business.

Rio Tinto’s operations in Australia and New Zealand are subject to state and federal regulations of general application governing mining and processing, land tenure and use, environmental requirements, including site specific environmental licences, permits and statutory authorisations, workplace health and safety, trade and export, corporations, competition, access to infrastructure, foreign investment and taxation. Some operations are conducted under specific agreements with the respective governments and associated acts of parliament.

In addition, Rio Tinto’s uranium operations in the Northern Territory, Australia and Namibia are subject to specific regulation in relation to mining and the export of uranium.

US and Canada-based operations are subject to local, state, provincial and national regulations governing mining and processing, access to infrastructure, land tenure and use, environmental aspects of operations, product and workplace health and safety, trade and export administration, corporations, competition, securities and taxation. In relation to hydroelectric power generation in Canada, water rights, as well as power sales and purchases, are regulated by the Quebec and British Columbia provincial agencies.

Rio Tinto’s operations in Europe are subject to national and European rules and regulations governing general and specific aspects of current and planned operations, notably land tenure and use, workplace health and safety, environmental issues, including applicable regulations in case of sale or closure of industrial sites and permit requirements concerning activities listed for environmental protection purposes, chemical risks management (REACH), competition requirements including compliance with antitrust rules, trade and export, corporations, intellectual property, labour requirements (including personal data protection), investment and taxation.

Rio Tinto’s South African-based operations are subject to black economic empowerment legislation which includes the requirement to transfer (for fair value) 26 per cent of the Group’s South African mining assets to historically disadvantaged South Africans by 2014.

Environmental regulation

Rio Tinto measures its performance against environmental regulation by rating incidents on a low, moderate, high, or critical scale of likelihood and consequence of impacting the environment. High and critical ratings are reported to the executive management team and the Committee on social and environmental accountability, including progress with remedial actions. Prosecutions and other breaches are also used to gauge Rio Tinto’s performance.

In 2010, there were 18 environment incidents rated high at Rio Tinto managed operations compared with 12 in 2009.

These incidents were of a nature to affect the environment or to concern local communities. Of these, nine resulted from water discharge, six were spills and three related to air emissions. Examples of these include:

  • discharge standards for water being exceeded and also the overflow of leachate from a landfill to an adjacent water course at Alucam, Cameroon.
  • leakage of unleaded petrol from a storage tank at Gove, Australia.
  • a spill of alumina and coke waste from the loading dock at the port for Alucam, Cameroon.
  • recorded levels for dust and tar in air emissions which exceeded permitted amounts on a number of occasions at Rotterdam, Holland.
  • flooding during a storm event which led to the overflow of water from the red mud retention dam onto land adjoining the facility at Gardanne, France.
  • overflow from a retention pond into local waterways during a high rainfall event at Kitimat, Canada.
  • flooding of sediment-laden water off site onto nearby land and creeks following heavy rainfall at Northparkes, Australia.
  • a pump failure at a weir during a storm resulted in an overflow of mine water into the local river at Palabora, South Africa.
  • recording of levels of SO2 in air emissions above permitted amounts on a number of occasions at Palabora, South Africa.

During 2010, 13 operations incurred fines amounting to US$540,328 (US$80,150 in 2009). Several fines paid in 2010 relate to incidents that occurred in 2008 and 2009. An amount of US$262,046 relates to an incident that occurred in September 2008 at a plant in Saguenay, Canada. An amount of US$174,697 relates to an incident that occurred in April 2009 at a port facility in Saguenay, Canada. An amount of US$48,527 relates to an incident that occurred in August 2008 at a plant in Saguenay, Canada.

Australian corporations that exceed specified thresholds are required under the Australian National Greenhouse and Energy Reporting Act 2007 to register and report on greenhouse gas emissions and energy use and production. Three Rio Tinto entities, Rio Tinto Limited, Alcan Gove Pty Limited and Pechiney Consolidated Australia Limited are separately covered by the Act. All three companies submitted their reports by the required 31 October 2010 deadline.

The same three Rio Tinto entities have obligations under the Australian Energy Efficiency Opportunities Act 2006 (EEO). All three completed the required annual public reporting for 2010. Eight operations undertook EEO assessments in 2010. This completed the first five year cycle of assessments for Rio Tinto corporations. EEO requirements continue to be communicated to all sites covered by the Act, with internal reporting and compliance systems augmented.

Further information in respect of the Group's environmental performance is included throughout this Annual report, and in the Sustainable development section.

The Group carries out exploration and research & development in support of its activites as described more fully under Exploration, and Technology & Innovation.

Research and development costs were US$187 million (2009: US$193 million).

Auditors

PricewaterhouseCoopers LLP and PricewaterhouseCoopers are the auditors of Rio Tinto plc and Rio Tinto Limited respectively. PricewaterhouseCoopers LLP have indicated their willingness to continue in office as auditors of Rio Tinto plc and a resolution to reappoint them as auditors of Rio Tinto plc will be proposed at the 2011 annual general meetings. The resolution will also seek authority for the Audit committee to determine their remuneration. PricewaterhouseCoopers will continue in office as auditors of Rio Tinto Limited.

A copy of the declaration given by PricewaterhouseCoopers as the Group’s external auditors to the directors in relation to the auditors’ compliance with the independence requirements of the Australian Corporations Act 2001 and the professional code of conduct for external auditors is set out in the Auditors independence declaration in the financial statements.

No person who was an officer of Rio Tinto during 2010 was a director or partner of the auditors at a time when the auditors conducted an audit of the Group.

Each person who held the office of director at the date the board resolved to approve this report makes the following statements:

  • so far as the directors are aware, there is no relevant audit information of which the auditor is unaware;
  • the directors have taken all steps that he or she ought to have taken as a director to make him or herself aware of any relevant audit information and to establish that the auditor is aware of that information.

Financial instruments

Details of the Group’s financial risk management objectives and policies and exposure to risk are described in note 33 to the 2010 financial statements.

Value of land

Most of the Group’s interests in mining properties and leases, and in other land and buildings have been included in the financial statements at cost in accordance with its accounting policies. It is not possible to estimate the market value of such interests in land as this will depend on product prices over the long term which will vary with market conditions.

Creditor payments

It is the Group’s policy to agree terms of payments with suppliers when entering into contracts and to meet its obligations accordingly. The Group does not follow any specific published code or standard on payment practice.

At 31 December 2010, there were 23 days’ (2009: 24 days) purchases outstanding in respect of the Group based on the total invoiced by suppliers during the year.

UK Financial Reporting Review Panel

Following discussions with the UK Financial Reporting Review Panel (FRRP), Rio Tinto has agreed to include certain additional information in the 2010 Annual report at the FRRP’s request. This information includes in the Social wellbeing section, additional details of the potential health risks posed by exposure to workers and communities surrounding uranium mines and details of the sensitivities the Group faces in dealing with local communities, such as at the La Granja copper development in Peru and the Eagle project in Michigan in the United States; in the Environmental stewardship section, an example of the potential for the Group's projects to impact on biodiversity, with information relating to biodiversity projects associated with the Group’s activities in Madagascar; in the Economic prosperity section, additional details of the nature of the Group’s interests in the non-managed Grasberg mine in Indonesia, the nature of the environmental risks and social issues relating to that mine; and reference to the sale of shares by the Norwegian Government Pension Fund in 2008 as an example of the possible impact of the reputational risks faced by the Group in relation to its non-managed operations.

Going concern

The directors, having made appropriate enquiries, have satisfied themselves that no material uncertainties that cast significant doubt about the ability of the Companies and the Group to continue as a going concern have been identified, and they have a reasonable expectation that the Group has adequate financial resources to continue in operational existence for the foreseeable future. Therefore, these financial statements have been prepared on a going concern basis.

The Directors’ report is made in accordance with a resolution of the board.
