Limiting the impact on the environment  
   
 
   
   
 

Environmental performance is managed as an integral part of our governance structure, from the board sustainability committee, to the executive management committee (Exco) sustainability and safety subcommittee. Accountable environmental managers and environmental practitioners ensure the effective implementation of environmental management systems throughout our business.

The current focus on securing continuity of supply, executing the build programme and responding to climate change provides us with environmental opportunities. These include introduction of renewable technologies, expansion of our nuclear programme, identification and implementation of internal energy-efficiency projects, further expansion of water conservation programmes, and conservation of land as a biodiversity offset.

Through this commitment, our objective is to ensure continual improvement in our environmental performance by setting environmental performance indicators and management systems and ensuring the use of balanced criteria in our decision-making processes. These commitments are set out in our safety, health and environment policy.

Our environmental commitment continues to be based on the efficient use of natural resources while controlling our activities that impact on the environment.

Performance

Environmental performance is co-ordinated at an organisational level and an overall picture of environmental performance is maintained.

We continue to measure our performance against a number of environmental parameters. Four of the most significant of these are linked to targets set annually in the Eskom business plan. Alarms and standards are set and measured against these four measures as part of the operational health dashboard.

 
Key environmental performance indicators   Unit of measure  Target

Actual 
2008 
Actual 
2007 
 Result 
Relative particulate emissions1,2   kg/MWh sent out  ≤0,21  0,21  0,20   Achieved 
Specific water consumption3   L/kWh sent out  ≤1,29  1,32  1,35   Not achieved 
Enhanced PreCare/MaxiCare environmental component   score ≤80,00  97,21  100,80   Exceeded 
Reported legal contraventions per the operational health dashboard4   number   Not achieved 

 

Over and above these indicators, performance against other significant environmental aspects of our operations is set out in the table below. The process of identifying our significant environmental aspects involves: 

  • identifying the environmental aspects and impacts associated with our activities
  • determining the significance of the environmental impacts
  • determining the significance of the impacts on business  ranking these aspects

  1. 1 Figures are calculated as a 12-month moving index.
  2. 2 Amount of ash emitted per unit of generated power sent out (excluding Camden and Grootvlei power stations –   correlation tests on environmental indicators not yet completed).
  3. 3 Volume of water consumed per unit of power sent out by all generating stations (excluding Camden and Grootvlei    power stations).
  4. 4 Under certain conditions, contraventions of environmental legislation are classified in terms of the Eskom   operational health dashboard index. These include instances where censure was received from authorities, legal   contraventions were not reported to government and internally, if it is a repeat legal contravention or where the   contravention was not addressed adequately. Managing directors can escalate any significant contravention to   Exco if deemed appropriate.
  5. 5 Calculated annual figures based on coal characteristics and power station design, but excludes gas-turbine
       power stations.
  6. 6 National Nuclear Regulator limit.
  7. 7 The reporting date of legal contraventions is based on its classification at the ELC. This may result in legal   contraventions from one year being reported in the following year.
