recycled for the 2010 financial year was 139,3 Mm$^{3}$, compared with 130,5 Mm$^{3}$ in 2009. Quantitative data on the water usage at each of our separate business units is provided in the operting reviews in this report. 

In addition to managing water use inside the factory fence, we recognise the importance of playing a meaningful role in supporting water resource management in the broader catchments within which we operate. Approximately 80% of the group’s total water requirements comes from the Vaal River system in South Africa, where our demand represents about 4% of the total off-take from this system. Following a water supply shortfall that was identified in this area in 2004, the R2,7 billion Vaal River Eastern Sub-system (VRESAP) pipeline project, in which Sasol has a 40% share, was commissioned to provide an additional reliable supply of water from the Vaal Dam to our Secunda operation and for use by the electricity utility, Eskom. This year VRESAP was declared operational by the Department of Water Affairs, although the project is not yet entirely completed. 

We appreciate the need for collective efforts – across sectors and stakeholder groups – in addressing the water challenge, and have been very active in various collaborative engagements (these are reviewed in more detail in our separate sustainable development report). In addition to our usual annual reporting on Sasol’s water footprint and risks, this year we also participated voluntarily in the Carbon Disclosure Project’s new water disclosure questionnaire. A publicly available report of the outcome of this initiative will be made available later in 2010. 

## Minimising our atmospheric pollutants 

The majority of our atmospheric e missions come from our two largest facilities in South Africa, Sasolburg and Secunda, both of which are situated in priority areas as defined by the recently promulgated National Environmental Management: Air Quality Act. Signifi cant investments will be required, and are being investigated, to ensure compliance with the minimum point source emission standards and ambient air quality standards required by the legislation. 

SD F urther details on our atmospheric emissions are provided in our online sustainable development report.

We have made progress this year in further reducing some of our atmospheric emissions throughout the group, with reductions achieved in our emissions of volatile organic compounds (VOCs), hydrogen sulphide and nitrogen oxides. As noted elsewhere in this report, we have also seen a reduction in the intensity of our greenhouse gas emissions.
