The Sustainability Report (Fuel & Energy ( ) > Sustainability) displays fleet carbon emissions to help you monitor output across locations to set more accurate targets and track progress toward your annual sustainability goals.
To refine the scope of the report results, use the date selector or filter by Tags or Attributes.
At the top of the Sustainability Report is a Total Emissions chart that provides a view of the emissions output of your fleet over time. By default, the report displays the date range of This Year, which enables you to track Current versus Projected carbon emissions output to stay on course with annual sustainability goals. To view average emissions for a specific period of time, hover over the data on the chart. You can also change the visual of the chart to a line graph or a bar graph with the widget selector in the top right corner.
The Sustainability Report includes a table that enables you to compare emissions output by vehicle or tag to identify the largest CO2 contributors in your fleet. You can view the following emission details, as applicable:
|
Field |
Description |
|---|---|
|
Vehicle or Tag |
The name of the vehicle or tag. |
|
Emissions or Total Emissions |
The emissions output of a vehicle, or the total emissions output of all vehicles in a tag. Total Emissions are calculated by multiplying fuel consumed (liter or gallon) by a defined emission factor based on the fuel type of the vehicle. See the Emission Factor table for more details. |
|
Average Emissions |
Average emissions calculated by dividing Total Emissions by Distance for a vehicle, or by Total Distance driven for all vehicles within a tag. This number makes it easier for you to compare fleet emissions by tag and identify areas of improvements. For example, if fleets are organized with tags based on locations, you can identify which location has better average emissions and coach more efficient driving behavior, and plan for more efficient routes. |
|
Distance or Total Distance |
The distance driven by a vehicle, or the total distance driven by all vehicles within a tag, as calculated in the Fuel & Energy Report. |
An emissions factor is the ratio between the quantity of pollutant emitted, and the activity conducted to release that pollutant. For example, kilograms of particulate emitted per gallon of gasoline burned. Samsara uses defined emissions factors from the EPA GHG Emissions Factor Hub to calculate the Emissions, Total Emissions, and Average Emissions in the Sustainability Report. Vehicles with other fuel types not listed in the following table will default to the CO2 emissions factor for gasoline. All emissions calculations are in kilograms (kg) for all regions.
The following emission factors from the EPA GHG Emissions Factor Hub are used in the Sustainability Report and Fuel & Energy Report to estimate CO2 emissions:
