Services examples
Calculating the carbon footprint of services follows
exactly the same steps as for goods: PAS 2050 specifies
a method that can be applied equally to services and
goods. However, correctly identifying and
understanding the service ‘product’ definition and the
life cycle stages in the process map may be more
challenging and may require extra effort to define.
When choosing a service to footprint, try to define it in
a way that would be most useful to the company and
others using the footprint, i.e. make it:
• easily comparable to other services within your or
your competitors’ offering
• likely to generate actionable opportunities to reduce
emissions
• relatively easy to understand and describe supply
chain/process map
Example 1: one night’s hotel
stay
Consider a hotel chain that wants to calculate the
carbon footprint of one night’s stay.
First, define the functional unit. Assuming the hotel has
different types of rooms, e.g. standard, deluxe, suite, it
is likely that each class or size of room has a different
footprint. To make a meaningful product definition, the
hotel company chooses to assess its typical standard
