In these proceedings of the 24th International Conference on Modelling, Monitoring and Management of Air Pollution, international academics and air pollution practitioners contribute to the evolving understanding of the science and policy contexts of air pollution.The management of air pollution is one of the most challenging problems facing the international community. A particular strength of the series has been the attention given to regulatory and, market solutions to air pollution management. The Air Pollution series of conferences has consistently acknowledged that science remains the key to identifying the nature and scale of air pollution impacts and reaffirmed that science is essential in the formulation of policy relevant information for regulatory decision making. The conference series also acknowledged, at a very early stage, that science alone will not improve a polluted atmosphere. The scientific knowledge derived from well-designed studies needs to be allied with further technical and economic studies in order to ensure cost effective and efficient mitigation. In turn, the science, technology and economic outcomes are necessary but not sufficient.
