Summary
This section provides an overview of the methodology that will be applied to the GHG assessment. It defines why the specific data is relevant, how it will be measured, and what categories or frameworks are used.
Why consider emissions from miscellaneous services?
Purpose: This is one of the main source of emissions for companies that aren’t producing goods. It is also a type of emissions that have always been difficult to assess precisely.
Here, we take into account the full upstream impact of the service company, through benchmarks
Type of raw data
Purpose: The model is based on a number of worked days per type of service
Granularity: Type of service, with some information about the travels or equipment purchase to refine the calculation
Measurement: The results is calculated per worked day General information
The model is based on benchmarks calculated using Greenly’s assessment between 2022 and 2024 (to ensure having sufficient data), filtered on scope 1+ scope 2 (location-based) + scope 3 (upstream), on the following company types:Security service: SecurityGuardingAndConciergeServices
Cleaning service: CleaningService
Audiovisual agency: AudiovisualProductionAndGraphicDesign, PhotographersAndVideographers
Lawyers: LawFirm
Training and teaching: TrainingAndAwareness
The module has been build around these 5 types of services since it was the ones for which it was possible to find similarities between companies inside Greenly’s data, and filter out outliers. The goal is to update these benchmarks annually, always based on three years of data.
Processing between methodologies
General information The only difference is that we count one average meal per worked day in BEGES, and not in GHG Protocol. The rest of the processing is the same.Comparison with the monetary and supplier approaches
Historically, we only had two ways to measure emissions from services: The monetary approach and the supplier specific approach.
Monetary approach: The emission factors used in this approach come from databases like ADEME one, also using industry benchmark but on a much larger scale. They’re applied to our categories, but are more generic than the ones calculated here, and there isn’t any precision possible like we do with the sub-types. We estimate the monetary approach to be less precise than this study
Supplier specific approach: The emission factors used here are calculated specifically for one company. They should be more precise than our benchmark approach, and should be favored (as long as the quality of the supplier’s assessment is validated)
Types of emission factors
General information
The emission factors used are calculated from our internal benchmarks
