Land Use and Transport Integration in Scotland (LATIS): A National Carbon Footprint

The interest in carbon emissions associated with the transport sector has intensified in recent years. The impact on carbon levels now forms a key indicator for the implementation of potential transport infrastructure, policy and land use interventions. The assessment tools available for calculating the environmental impact or benefits of transport decisions are becoming an important aspect in the appraisal process. Transport Scotland’s Land use and Transport Integration in Scotland (LATIS) service provides a land use and transport modeling framework which covers the whole of the Scottish strategic road and public transport network. The framework forecasts changes in land use, traffic levels and travel patterns over time, and can appraise impacts associated with the introduction of transport schemes or policy decisions. It can also forecast changes in traffic and travel levels associated with different economic or demographic scenarios. The framework uses a combination of traffic levels and traffic speed data to generate a ‘National Carbon Footprint’ which covers road transport-related emissions. These calculations also include forecast changes to engine and fuel efficiency over time along with an ability to vary composition of the vehicle fleet. This ‘footprint’ offers a national perspective and provides a mechanism to assess the potential for transport interventions to help deliver the challenging targets proposed for reducing carbon emissions. This paper will describe how the LATIS framework calculates a national carbon footprint and discuss comparisons to other carbon calculation methods. It will also demonstrate how the various interactions between land uses, demographic changes, transport interventions and technology are combined to predict the potential changes to the level of Scottish road transport-related carbon emissions over time.
