In addition to the above, during 2011, 0.1 kilotonnes (kt) of CO2e were emitted through the consumption of A1 jet fuel at the Vaal River operation. A1 jet fuel use was reported as 0.2kt for 2010. At the Vaal River operation 39kt of CO2e were emitted during the consumption of coal.

In 2010 this use amounted to 49kt of CO2e. Approximately 0.7 kilotonne of CO2e was generated annually over 2011 at CC&V as a result of combusting lubrication oil for heating the heavy mining equipment (truck) workshop.

In addition, 0.14kt of CO2e were emitted from liquified petroleum gas (LPG) use in 2011 at CC&V. At AGA Mineração 0.59kt of CO2e were generated owing to the consumption of LPG.

Refrigerants were lost at the South African operations 840 kg of R11 lost at West Wits in 2011 equivalent to 3 kt of CO2e. In addition, 6.8 t of R134a was lost at West Wits and 3.5 t of R134a at Vaal River, equivalent to 9.7 kt CO2e and 4.9kt CO2e respectively. During 2010, 9.4t of R134a refrigerant was lost at Vaal River and 25t at West Wits equivalent to 14kt CO2e and 35kt CO2e respectively.

EN17

Global Compact ICMM

The information below provides disclosure under the Global Reporting Initiative (GRI) indicator EN17: Other relevant indirect greenhouse gas emissions by weight.

During 2008 and 2009, AngloGold Ashanti carried out a detailed and independent GHG emissions assessment. Scope 3 emissions were included in this assessment and were found to be 0.4% of the group’s total emissions. The company’s emissions profile has not changed substantially since the assessment was carried out. Consequently, these other indirect GHG emissions are deemed to be immaterial.

The information below provides disclosure under the Global Reporting Initiative (GRI) indicator EC2: Financial implications and other risks and opportunities due to climate change.

Financial implications of climate change

A comprehensive risk assessment was carried out during 2008/9 to determine the level of risk to which the company is exposed as a result of climate change. Various risk categories including financial and investment risk, risk owing to government policies and legislation, and physical risk, including local community vulnerabilities were considered. Key points include proactively assessing these risks and how being proactive could be used to the company’s competitive advantage. Also considered was the fact that, while regulatory requirements will become stricter in the near future, there will be differences in regulatory requirements across jurisdictions, which may in turn present both opportunities and challenges.

Some of the regulatory risks have already resulted in increased compliance costs for AngloGold Ashanti’s power suppliers whose costs are passed through to the company in the form of price increases. For instance, in South Africa, AngloGold Ashanti pays a levy of ZAR0,025 (recently increased to ZAR0.035) per kWh for electricity generated from fossil fuels. In February 2012, the South African Minister of Finance announced his intention to introduce a carbon tax in 2013, with a draft discussion paper setting out proposed details to be published in 2012.

The Australian government approved legislation for the Clean Energy Future Scheme in November 2011. Under the applicable requirements, approximately five hundred of Australia’s biggest emitters, including AngloGold Ashanti, will pay A$23 per tonne of carbon dioxide they generate from July 2012. The charge will increase by 2.5% each year until 2015, when it will be set by the market under a trading scheme.

In addition, AngloGold Ashanti’s operations could be exposed to a number of physical risks from climate change such as increased rainfall, reduced water availability, higher temperatures and extreme weather conditions. Events such as flooding or inadequate water supplies could disrupt the company’s mining and transport operations, mineral processing and rehabilitation efforts, and could increase health and safety risks on site. Such events could also have adverse effects such as increased incidence of pests and disease prevalence in the company’s workforce and in communities in close proximity to the company’s operations.

Ozone-depleting emissions

Ozone-depleting substances totalling 3,864 kg (R11) were accidentally emitted from the West Wits operations during 2011. During 2010, 1,198kg (R11) were accidentally emitted from the West Wits operations.
