9	This tool calculates the CO2, CH4 and N2O emissions from: n Vehicles that are owned/controlled by you, including freight lorries. n Public transport by road, rail, air and water. n Mobile machinery, such as agricultural and construction equipment.		The tool uses default emission factors, which vary by country. Currently, separate sets of emission factors are available for the UK and US. For other countries, if more specific emission factors are not available, companies should select the ‘Other’ category. This category uses either global default values or UK-specific values -- it will therefore lead to less accurate calculations. On the settings tab, users can supply custom emission factors or adjust the default global warming potentials.
10	What data do I need? Fuel use data are most accurate for calculating CO2 emissions, while distance-traveled data are most accurate for calculating CH4 and N2O emissions. So, for non-public transport sources, the recommended approach is to provide both fuel use and distance data. Where one type of data is unavailable, the tool uses fuel economy information (where available) to convert between these data types. Because CO2 contributes most to GHG emissions (>95%), companies should first strive to improve their fuel use records. Please note that the emission from on-road freight transport can be calculated using vehicle distance or weight-distance data.

18		The emission factors used in this tool come from the UK Dept. for Environment, Food and Rural Affairs (DEFRA), the US Environmental Protection Agency (EPA) and the Intergovernmental Panel on Climate Change’s (IPCC) 2006 Guidelines for National Greenhouse Gas Inventories. The tool was developed by Clear Standards Inc. in collaboration with WRI. Please cite this tool using the following format: World Resources Institute (2015). GHG Protocol tool for mobile combustion. Version 2.6. While the worksheets are largely self explanatory, for questions or suggestions on its contents, please contact the GHG Protocol at: ghgquestions@wri.org Other tools can be downloaded from the GHG Protocol website.
