How can a small company estimate employee commuting emissions?
Run a short survey: how each person travels, how far and how many days a week. Multiply distance by a factor for each mode and add up. Commuting is Scope 3 category 7, optional for most MSMEs, but buyers sometimes ask and a one-page survey answers it.
The survey
- Mode: two-wheeler, car, bus, company bus, walk or cycle.
- One-way distance.
- Days a week on site.
The calculation
Distance times two times working days times a factor per km for each mode. Published factors such as the UK government's are a reasonable start; label them as defaults.
Company buses
A bus you own or lease and fuel is Scope 1, not commuting. A contracted bus service is commuting.
What Senseible does here
Senseible reads your fuel, electricity and purchase documents into dated, fingerprinted records, so the figure you send a buyer can be traced to its source.
