What is NOT a consideration under a whole-life carbon assessment?

Whole-life carbon assessment is an approach that evaluates the total carbon emissions associated with a building or infrastructure project throughout its entire lifecycle. This includes various stages such as raw material extraction, transportation, construction, operation, maintenance, and deconstruction.

The consideration of operational emissions is crucial because it represents the carbon emissions generated during the building's use phase, which can have a significant impact on overall carbon footprint. Maintenance emissions are also important, as ongoing maintenance activities can contribute to additional carbon outputs over time. Construction emissions are a key aspect as well, as they account for the carbon produced during the physical building process.

In contrast, the option regarding only renewable energy sources does not fit within the framework of whole-life carbon assessment. While the use of renewable energy is beneficial for reducing operational emissions, having a focus exclusively on renewable sources overlooks the broader scope of a whole-life carbon assessment, which includes all emission types from the project's inception to its end of life. Thus, it is not a consideration under this comprehensive evaluation approach.
