The Cape Town Brown Haze Study report attributed 65% of the visible pollution to vehicular emissions, of which 49% is caused by diesel driven vehicle emissions. In a business as usual scenario, air pollution is projected to increase by 48% over the next decade. When these results were released, the Cape Metropolitan Council, being the authority responsible for the control of air pollution within the CMA, immediately set about devising an action plan to reduce the incidence of brown haze. These actions were divided into objectives that can be implemented locally and those that require national input. The local objectives were all successfully implimented. The objectives that require national input, such as fuel reformulation and reviewing the legislation was brought to the attention of the various national ministers. Action on these aspects has been slow.
