Editorial scope guide. The points are also available as readable text below.
Деталь из углеродного волокна не следует называть экологически устойчивой только потому, что она легкая. Спросите, с чем проводится сравнение, какие этапы жизненного цикла учитываются и какими доказательствами подкрепляется заявление об экологичности.
Define the claim before requesting data
Distinguish recycled content, reduced manufacturing waste, lower use-phase energy and end-of-life recovery. These describe different things. Record the component boundary and the service assumptions behind a comparison so the result can be interpreted rather than repeated as a general claim.
Keep missing evidence visible
A supplier may have material records without having a completed life-cycle assessment for the final part. State that limitation clearly. Ask for the source, calculation boundary and relevant configuration when a quantified saving is offered. Do not transfer a result for another vehicle, material grade or recycling route to the part being purchased.
Example scenario
A proposed part contains recovered fibre, but no life-cycle comparison has been completed. Report the documented recycled-content statement on its own. Do not turn it into an unsupported claim that the whole product has a lower carbon footprint.
Points to record
| Claim type | Separate recycled content, waste reduction and life-cycle impact. |
|---|---|
| Comparison basis | Identify the baseline part, scope and service assumptions. |
| Доказательства | Record the source, calculation method and limitations. |
