Sustainable Development Matrix<br />

Indica<strong>to</strong>r Score Comment<br />

Water: Water quantity: This indica<strong>to</strong>r is used <strong>to</strong><br />

evaluate the project’s contribution <strong>to</strong> water<br />

availability and access locally and regionally.<br />

Number of people with access <strong>to</strong> water supply in<br />

comparison with the baseline.<br />

Water quality: This indica<strong>to</strong>r is used <strong>to</strong> evaluate<br />

the contribution of the project <strong>to</strong> water quality<br />

locally and regionally in the project’s area in<br />

comparison with the baseline. Water quality will be<br />

measured using concentration of main pollutants<br />

(including BOD and others) in any effluents<br />

generated by the project activity and their<br />

contribution, if any, <strong>to</strong> local water quality.<br />

Dependent on the result of the EIA, both quantity<br />

and quality assessment should discuss seasonal<br />

variation of availability and quality in addition <strong>to</strong><br />

mean annual data due <strong>to</strong> the fact that mean<br />

annual data might not be sufficient <strong>to</strong> provide full<br />

understanding of impacts of the project activity<br />

against the baseline.<br />

Air quality: This indica<strong>to</strong>r is used <strong>to</strong> evaluate the<br />

contribution of the project <strong>to</strong> local air quality. Air<br />

quality will be measured by comparing the<br />

concentration of most relevant air pollutants (e.g.:<br />

SOx, NOx, particulate matters etc.) generated by<br />

the project activity with the baseline.<br />

Other pollutants: This indica<strong>to</strong>r is used <strong>to</strong> evaluate<br />

the contribution of the project activity <strong>to</strong> reducing<br />

the flow of pollutants not already considered <strong>to</strong> the<br />

environment, including solid, liquid and gaseous<br />

wastes.<br />

Soil condition: This indica<strong>to</strong>r is used <strong>to</strong> evaluate<br />

the contribution of the project activity <strong>to</strong> local soil<br />

condition. Soil condition will be measured by<br />

1 The water quality is affected in a positive<br />

way. Wood chips that are used for firing of<br />

the boilers originate from the processing of<br />

sawdust that currently accumulates on large<br />

heaps. According <strong>to</strong> local fishermen,<br />

effluent of these heaps through leaching<br />

has an adverse impact on the water quality.<br />

This can be considered a minor positive<br />

impact.<br />

0 Several studies 8 . show that the Project<br />

Activity (biomass burning) emits similar if<br />

not less amounts of relevant air pollutants<br />

(e.g.: SOx, NOx, particulate matters etc.)<br />

than the baseline (coal burning). An<br />

indica<strong>to</strong>r of 0 is therefore conservative.<br />

1 At present the ash from the boilers at<br />

<strong>Letaba</strong> is landfilled on the property. In the<br />

Project Activity less waste will be produced<br />

(because the coal has a 14% ash content<br />

and the biomass only 3%) and it will be<br />

landfilled as before. If all peels are dried<br />

and none are landfilled, methane formation<br />

will be further avoided on the <strong>Letaba</strong> landfill<br />

(no VERs will be claimed for this).<br />

0 Soil erosion and land use changes are not<br />

impacted, since the biomass in the form of<br />

Eucalyptus and Pine sawdust is renewable<br />
