EMBEDDED IMPACTS METHODOLOGY
Info
Embedded impacts include the impacts occurring during raw material extraction, manufacture, transport and end of life phases.
Components impacts
Variable components impacts
The impacts of variable components are assessed from the component characteristics.
Warning
For now end of life is not taken into account.
Fixed components impacts
The impacts of fixed components are set by default
Warning
For now end of life is not taken into account.
Device & services impacts
The data and methods are specified for each device or service in their dedicated page.
Two strategies exist
1. Bottom-up approach
Embedded impacts are assessed at component level and aggregated at device level with a bottom-up approach.
Warning
In this case, end of life is not taken into account for now.
2. Fix impacts factors
If component impacts cannot be assessed, we use non-specific impacts factors at device level.
Warning
In this case, all the life cycle is taken into account including end of life.
Allocation
Embedded impacts can be reported with several allocation strategies.
Over the lifecycle
When no specific duration is given, the total embedded impacts of the asset are given.
embedded_impacts = total_impact
Over a specific duration
When a duration is given as a query parameter, we allocate the embedded impacts linearly on this duration.
embedded_impacts = total_impacts * (duration/life_duration)
