Scope 3 business travel and employee commuting: how to log both

Scope 3 business travel and employee commuting are the two value-chain categories Karbon360 covers today. They are the ones customer questionnaires and bank templates ask for first, and every report states the boundary honestly as two of fifteen categories.

Scope 3 business travel (category 6)

  1. Go to Scope 3, then Business travel, then Add trip.
  2. Choose the mode: flight, rail, bus or car.
  3. For flights choose the haul (short, medium or long) and the class (economy or business).
  4. Enter distance in km, or the number of trips, and repeat for each month of travel.

Sources: travel agency statements, expense claims and booking confirmations. A monthly total per mode is fine.

Employee commuting (category 7)

  1. Go to Scope 3, then Commuting, then Survey.
  2. For each facility, enter how many employees commute by each mode (car, bus, walking or cycling), the average one-way distance and the working days.
  3. Karbon360 calculates annual commuting emissions and spreads them across the period.
  4. Repeat the survey once a year, or when headcount changes significantly.

The source is a short staff survey or HR data. Survey-based figures are marked as estimated.

The other thirteen categories

Purchased goods, transport, waste and the other categories are on the roadmap, prioritised by customer demand. If a questionnaire asks for them, answer that they are outside the current boundary. See all fifteen in Scope 3 categories explained.
