# What is a Product Carbon Footprint (PCF)?

The PCF measures the carbon equivalent emissions attributable to a product. It is not linked to a specific timeframe, and include all the lifecycle stages and by-products involved in producing a product

It estimate the total emissions of greenhouse gas (GHG) associated with a specific product throughout its life cycle

**Cradle-to-gate PCF** includes product related emissions of scope 1, 2and of upstream Scope 3 emissions

**Cradle-to-grave PCF** includes product related emissions of all scopes (1, 2 et all of scope 3including downstream emissions)

## 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://knowledge.co2ai.com/provide-product-emissions-data/what-is-a-product-carbon-footprint-pcf.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.
