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 waste?
Waste emissions are representing the last step of a product life. It covers the waste collection, and usually the processing of this waste.
The main type of waste processing are:
- Landfill: Disposal of waste by depositing or burying on or in the ground.
-Incineration: Energetic valorization
-Recycling: Any recovery operation by which waste, including organic waste, are reprocessed into substances, materials or products for their original function or for other purposes
-Composting, Methanisation: (an)aerobic transformation process of fermentable materials
Type of raw data
Purpose: Type of waste
Granularity: Weight
Measurement: Tonnes General information Lightweight module
3 different lightweight modules are available:BEGES (For BEGES methodo only)
GHG P (Used for all GHG P companies except UK)
UK (Only used for UK companies)
They’re used the same way, but are using different databases (ADEME, EPA and UK), since these database don’t measure exactly the same perimeter:Base Empreinte ADEME: This is the database to be used for a BEGES client. All the EFs are taking into account the full waste management process.
EPA(United States Environmental Protection Agency): Used for all GHG P clients except the UK ones. Emission factors from EPA take into account the transportation to recycling facility and first sorting of waste. For landfills, they also take into account the waste management phase.
UK GHG Conversion Factors: Used for UK clients only, this database takes into account the transportation of the waste only, except for the landfill EFs, where waste management is also included.
Since we’re using different database, the list of emission factors isn’t exactly the same in each lightweight. The EF selection should be done on the closest match, without looking for an exact match everytime, knowing these databases have a limited set of emission factors.
Advanced module
The advanced module is also based on these 3 databases, but with an extended list of emission factors, taking into account more types of waste
Processing between methodologies
General information
Lightweight module
Data processing is exactly the same, whether the assessment’s referential is GHG Protocol or BEGES. Only the EFs are changing.
