The generation of power within Southern Africa is reviewed. A study is described in which the emission factors for CO2 and NOx were determined experimentally across a wide range of power stations and technologies, and compared to the IPCC default factors. It was found that the CO2 emission factors tended to be at the upper end of the IPCC default range, whereas the NOx emission factors were generally below the low end. The results from South Africa tend to dominate the regional picture at present, but this is likely to change in the near future, as Botswana has announced plans to introduce over 4 000 MWe of coal-fired power stations.

Keywords: SADC, climate change, power sector, emission factor, greenhouse gas
