Employee commuting is Scope 3 Category 7. It covers your staff travelling between home and work, and in most frameworks the energy they use working from home.

You need two things: how your people travel, and how often.

Keep it short. A long survey gets a low response rate, and a low response rate is a bigger problem than a rough question.

Ask for:

That is enough to calculate. Anything else is optional.

Home postcode. Staff object, and you only need the distance. Ask for the distance instead.

Exact vehicle detail. A generic car factor is close enough for a category this size.

Name or email, unless you need to chase non-responders. If you do, say why you are collecting it.

People who commute between two sites. A single question asking which sites they travel between catches this. Otherwise their travel is understated.

Company vehicles. Staff driving a company car are already in your Scope 1. Ask, and exclude those responses from Category 7 so you do not count them twice.

Mixed modes. Most people vary by day. Asking for days per week per mode is more accurate than asking for a single usual mode.

Run the survey however suits you. Avarni does not need to host it.

Once you have the responses, prepare a spreadsheet and upload it against a Method configured for commuting, or send the responses to your Avarni lead.

You will not get everyone. Apply the average result of your responders to the rest of your workforce, and record the response rate.

This is an estimate and it needs documenting. See Estimate what you cannot measure.

Working from home is energy used in someone's house on a working day, usually calculated per person per day.

Two decisions to make and record:

Staff in other countries need a factor for that country, not an Australian one.

Annually is enough. Run it at a representative time of year, not during a holiday period, and use the same month each year so your figures stay comparable.
