# End-of-Use (C2)

The End-of-Use Stage (C2) refers to the transportation of deconstructed or demolished building materials from the site to a waste processing facility. 

**C2 - Transport to Waste Processing**: This stage encompasses the transportation of deconstructed or demolished building materials from the site to a waste processing facility.

**Waste Segregation and Collection**: Building materials must be segregated and collected before transport. Some materials can be recycled or reused, while others need to be disposed of properly. The efficiency and accuracy of this process can significantly influence the emissions during the transport stage.

**Transport of Materials**: This sub-stage involves the actual transportation of these materials from the demolition site to the waste processing facility. The distance travelled, the mode of transportation, and the efficiency of the load can all affect the emissions associated with this stage.

**Emissions from Vehicles**: This involves the emissions produced by vehicles used in transportation. These can include exhaust emissions from the combustion of fossil fuels and any indirect emissions associated with the production and distribution of these fuels.

Efficient planning and management during this stage can help reduce its environmental impact. This can include efforts to minimize the distance materials need to be transported, optimising load efficiency, or using more sustainable transport modes. Additionally, efforts to maximize the reuse or recycling of materials can help to reduce the overall emissions associated with the end-of-life stage of a building.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.betterbuilding.io/user-guide/workflows/carbon/end-of-use-c2.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
