The calculator element of the REAP Petite tool is very detailed and covers more sectors than many other tools. Increasing the level of detail of questions should make for an accurate estimation of the individual's footprint. The visual representation of data in the analysis section is very clear and useful to enable comparisons across community members, average households in different regsions and with UK averages. However, there are limitations in the accuracy of the carbon and ecological footprint calculations partly owing to the use of averages and 'are you above/below average' type questions. Furthermore, the travel related questions were found to be confusing. The tool is not available online so there may be logistical difficulties in getting data for many households into the system without duplicating data entry from a survey and it also does not allow data to be shared once it is compiled. Any updates of emission factors or other assumptions would require updates to the standalone tool.
