There are three Employee Commute calculation methods to choose from:
Distance travelled per commuting type uses the total distance travelled per commuting type, including bike or foot, public transportation, car, motorcycle, electric bike, electric car, electric motorcycle, or electric scooter. The distance travelled refers to the total distance of all employees' round trips (to and from work) per mode of transport in the selected timeframe. This is our recommended calculation method as it provides the most accurate results.
Number of commuters per mode of transport uses the number of (absolute, not FTE) employees commuting by each mode of transportation (public transport, private cars, and bike/foot). Please note that electric and hybrid vehicles are not yet supported by this method.
Bring Your Own Emissions allows you to upload your own pre-calculated emissions to the Plan A platform. For more information, see here.
We recommend calculation methods based on their accuracy but ultimately you should choose a calculation method that fits the data you have access to.
Calculating Work From Home Emissions
According to the GHG Protocol, Work From Home emissions fall under the category, Scope 3, Category 7 'Employee Commute'.
The data you provide about your employees' Work From Home patterns, however, can also impact calculations for other emissions categories. For instance, when you use national averages for Purchased electricity, Purchased heat, or Waste generated in operations, we utilise your Work From Home patterns to estimate consumption levels of electricity, heat, and waste per employee working in-person at the facility. This helps us to make sure our national average estimations most closely reflect the reality of your organisation's operations.
Therefore, because of it's wide usage across categories, your data is uploaded as part of the Organisational Data template, and not through the Employee Commute 'Collect and Update' page. Nonetheless, your Work From Home emissions can be found on the Employee Commute dashboard on the Measure page, as per the GHG Protocol's categorisation.
Calculating Work From Home Emissions through Organisational Data uses the average number of work from home days per week, working days per week, number of employees, number of employees who work from home at least 1 day per week, and average working hours per day.
National Averages
When specific data is unavailable, National Averages can be used to calculate emissions. National Averages represent the average values for a given type of activity data within a specific country.
National Averages will be shown automatically when you have uploaded Organisational Data and haven't uploaded any data for Employee Commute.
If you don’t want to use National Averages to calculate emissions you can upload a template with the value set to 0 for the respective time and facility.
