The 'Travel Emissions Profiles' project was centered around a report, published as part of the EFFORT project. It was based around an exploratory yet innovative approach to travel auditing, using the methodology of self-assessment of travel characteristics from personal car-based travel. The output is a series of personal and household annual emission budgets which identify the sources and distribution of emissions for car-based travel and show the proportion of residents contributing to emissions at each level. These budgets are supplemented with some attitudinal data to aid the identification of opportunities for less polluting travel patterns. Funding for SMART was provided by the European Commission, Nuclear Electric, Oxfordshire County Council and PowerGen.
