Millions of tonnes of building materials are transported each year across the UK from quarries to major towns and cities, which are essential for maintaining our economy and lifestyles. However, the transportation of such materials (aggregates) causes constant concerns in regards to pollution and carbon emissions. Reducing this significant carbon footprint in the face of accelerating demand for these construction materials is a major challenge facing the aggregates industries and its regulators over the next 30 years. The research aims to Improve our knowledge and understanding of the environmental implications of the transport of aggregates and hence improve the sustainability of the transfers of aggregates (i.e. reducing carbon emissions). The aims of this thesis is to describe the construction of a spatial planning support system for evaluating the sustainability of aggregates minerals supply and transportation options, and to establish a framework for evaluation of policy alternatives for the sustainable provision of aggregates in the future. The planning support system is made up of a GIS containing a set of spatial models, including a transport model, a spatial interaction model (SIM), a series of spatial impact models and a multi-criteria evaluation (MCE) framework, underpinned by a detailed network of road and rail routes across the UK. The transport model generates the Origin-Destination (O-D) cost matrix for the SIM; then the SIM estimates the flows of aggregates between every pair of origin and destination; the spatial impact models are used to evaluate carbon emissions and other environmental, socio-economical impacts associated with both the production and transportation of aggregates; then the MCE framework is used to evaluate each policy based on the spatial impact indices generated by the spatial impact models. A series of what-if scenarios are then set up which look at how changes in any part of the transport process will impact on carbon emissions and other environmental and socio-economical concerns. These scenarios include: changing in supply side (i.e. open or closing quarries), demand side (i.e. new infrastructure project) or transport policies (i.e. reducing rail price).
