Direct and indirect greenhouse gas emissions by weight

The data below provides disclosure under the Global Reporting Initiative (GRI) indicator EN16: Total direct and indirect greenhouse gas emissions by weight.

* Restated from 2009, due to a calculation error

In addition to the above, during 2010, 0.2 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 2009. At the Vaal River operation 49kt of CO₂e were emitted during the consumption of coal. In 2009 this use amounted to 41kt of CO₂e. One kilotonne of CO₂e was generated annually over 2009 and 2010 at CC&V as a result of combusting lubrication oil for heating the heavy mining equipment (truck) workshop. In addition, 0.18kt of CO₂e were emitted from liquified petroleum gas (LPG) use in 2010 at CC&V. At AGA Mineração 0.56kt of CO₂e were generated owing to the consumption of LPG.

Refrigerants were lost at the South African operations. 1,198 kg of R11 lost at West Wits in 2010 equivalent to 6kt of CO₂e. In addition, 25t of R134a was lost at West Wits and 9.4t of R134a at Vaal River, equivalent to 35kt CO₂e and 14kt CO₂e respectively. During 2009, 10.7t of R134a refrigerant was lost at Vaal River and 22t at West Wits equivalent to 15kt CO₂e and 32kt CO₂e respectively.
